PLC control two pump start-up failure solutions to problems

December 4th, 2014 at 03:29 am



Situation:in the double liang steam double-effect lithium bromide absorption air-conditioning unit,the use of omron PLC (PA204S C200HE-CPU42,power supply) to control the start of two pumps. When,in turn,start the two pumps,often led to the suspension of the power of the PLC,thus stop running program.Second,the detection of 1,use the meter to measure the voltage electric motor 12v 500w waveform of two pump ordinal startup PLC power PA204S ac voltage of the power supply change found:when did not start the electrical motor 12v 1000w pump,the voltage of the power supply is normal,when start the two pumps,instantaneous fell to the power supply voltage of 184 v,184 v and the duration of the above 25 ms,PLC to stop working,and to determine the effect of pump power of PLC.2,in order to solve this problem,respectively for the following tests: A) driving the pump first,delay around 10 s to start small pump,power supply voltage drop to about 190 v,the instructions first,pump makes instantaneous voltage drops,later start small pump,affect smaller,but it need to modify the PLC program.B) because the pump power supply is turned by high tension line through a transformer,transformer capacity,can be considered a large capacity of transformer,may make the pump will be smaller influence on the PLC power supply voltage.C) in the PLC power supply termination a large capacitance,but the effect is not obvious.D) finally in one power supply transformer converted by a 220 v power supply to PLC,found that even in the start two pumps at the same time,PLC power supply voltage drop is only about 204 v,204 v,the can.Conclusion:as a result acmotortrading.blogspot.com of the PLC power supply is supplied with water pump in the same way,and the plant's transformer capacity is small,so in the start two pumps,caused the PLC power supply voltage drops below 85% of rated voltage,and duration of more than 10 ms,resulting in PLC detected power interruption,stop working. So the advice from the transformer converted one by one in the 220 v power to separate for PLC,which can solve the problem.

Although the stepper motor with strong ability,high precision,rapid start-up speed the characteristics of easy to control,but in the actual operation process due to improper start and stop control,select the appropriate size three-phase asynchronous motor power still started shaking and stops the phenomenon of overshoot,from surface affect the control precision of the system.Especially the work in the frequent start and stop a step motor,this kind of phenomenon is more obvious [2].This paper proposes a kind of stepping motor based on single chip microcomputer control discrete acceleration and deceleration control method.Ordinate is frequency f,the unit for pulse/SEC or step/SEC.Abscissa time t,www.dongfeng-motor.com the unit is in seconds.Stepper motor to f0 accelerate starts to run time t1 the highest frequency f,and then run at a constant speed,to t2 time began to slow,in t5 moment motor stalling,the total number of N.The motor from static accelerated to the highest operating frequency and the highest operating frequency to stop to the is the key to the stepper motor control,usually adopt uniform acceleration and deceleration mode.Deceleration control of stepping motor by single chip microcomputer,in fact is to change the output pulse interval,software and hardware can be used two ways.Software methods rely on delay program to change the frequency of the pulse output,ac synchronous motor of which the length of the delay is dynamic,and the method because of the need to constantly produce control pulse,occupies a large amount of CPU time; Hardware methods depend on single chip microcomputer internal timer to achieve,after each into the timer interrupt,change the time constant of timer (load),a two-dimensional table as a controlled object by stepping motor drives the ball screw in the X/Y direction linkage.This paper discusses a kind of a circular trajectory with minimal parameters of interpolation method and the method of step motor frequency control of motor speed.Stepping motor control system of the development of the hardware and software collaborative simulation method was adopted,the system development cycle and cost can be centrifugal pump greatly reduced by acc when the pulse frequency increases gradually,slows down the pulse frequency decreases.How to identify qualified factory motor? This method takes up less CPU time,it is a kind of high efficiency of stepping motor speed control method.Considering the single chip microcomputer resources (word length) and programming is convenient,the timer does not need to be calculated every step loading value.As shown in figure 3,using the discrete method to deceleration curve discretization.Rising speed is points after discretization steps,and every rise a step in the steps to keep for a period of time,to overcome the stepper motor rotor velocity lag caused by the moment of inertia.Only when the actual speed reaches preset to accelerating,actually also automatically correct local velocity error.

Electric motor, Electric motor), also known as the motor or motor

August 1st, 2014 at 04:53 am


Electric motor, Electric motor), also known as motor or motor, is a kind of electrical energy into mechanical energy, mechanical energy and can be used to produce kinetic energy, electrical equipment used to drive other devices. The various types of motor, but can be roughly divided into ac motor and dc motor to be used for different occasions To compare DC Motor (DC Motor) in the speed for the benefits of relatively simple, only control the size of the voltage has control of speed, but this kind of Motor is unfavorable in operating conditions such as high temperature, flammable, and due to the need to carbon brush Motor (am) as current converter components (brush Motor), so need to regular cleaning brush friction generated by dirt. lamination motor No carbon brush motor is called the brushless motor, relative to the brush, brushless motor because of less carbon brush and shaft friction so more save electricity and quieter. Production difficulty is higher, the price also is higher. AC Motor (AC Motor), on the other hand, works under high temperature, flammable, and need not regular cleaning of carbon brush dirt, but in the speed is more difficult, because the control of AC Motor speed to control the frequency of the alternating current (or the use of induction motors, with increased internal resistance decreased under the same the frequency of the alternating current Motor speed), the control of the voltage will only affect the torque of the Motor. General civil motor voltage of 110 v and 220 v two kinds, such as in industrial applications and 380 v or 440 v type. The development history In 1835, produced the world's first motor can drive the application of small trolley for us a Smith of Wen Bo (Thomas Davenport). In the early 1870 s, the world's earliest available commercial motor by the Belgian electrical engineer Zenobe Theophile Gamme invention. In 1888, a famous motor part American inventor nikola tesla used Faraday electromagnetic induction principle, invention of ac motor, is the induction motor. In 1845, the British physicist huis (Wheatstone) to apply for the patent of the linear motor, but the principle in the 1960 s were seriously, and design the practicability of the linear motor, the current has been widely applied in industry. In 1902, the Swedish engineer Dan nelson use tesla induction motor rotating magnetic field of the concept, invented the synchronous motor. In 1923, the Scot James Weir French invented type three-phase Variable reluctance (Variable reluctance) stepper motor. In 1962, through the help of hall element, a practical DC brushless motor finally. In the 1980 s, the utility of ultrasound motor starts. The principle of The basis of the rotation of the motor principle for Buddha to Ming left hand rule, when a conductor is placed in a magnetic field, if the conductor is applying a current, wire will cut magnetic lines to make wires produce movement. Current into the coil magnetic field, using magnetic effect of current, make the electromagnet in fixed magnet rotating device in a row, can convert electrical energy into mechanical energy. With a permanent magnet or produced by another group of coil magnetic field interact to produce power Is the principle of dc motor stator, the rotor in accordance with the interaction force generated by the direction of the movement. Ac motor stator winding coil is on alternating current (ac), to produce a rotating magnetic field, rotor rotating magnetic field to attract together to make the basic construction of dc motor including rotary motion "armature", "field magnet", "the collector ring", "brush". Armature: can around the axis of rotation of the soft iron core coil. Field magnet: produce the magnetic field strength permanent magnet or electromagnet. Collector ring: coil two ends to about two semicircle collector ring, with the coil rotation, to change the direction of the current device. Each roll (180 degrees), half a circle on the coil current direction will change again. Brush, usually made from carbon brush contact collector ring fixed position, used to connect to the power supply. The basic structure Many different kinds of motor, with the basic structure, www.dongfeng-motor.com its composition is mainly composed of the Stator (Stator) and the Rotor (Rotor). Stationary in the space of the stator, the rotor can be circuition, is supported by bearings. To expect a certain air gap between the stator and rotor, to ensure that the rotor can free rotation. On the stator and rotor winding coil, a magnetic field on the current, become electromagnet, the stator and rotor one of them for a permanent magnet.

2014 ford agreement multiple covers levels of rivalry on development

July 31st, 2014 at 07:40 am


A new new multiple sedan is necesary, It seems that toyota is literally in due course ready boost and additionally give.But rather than one variation along with contract, There can be two to have: The specific agreement Plug where last month found its way to used parts; Then an additional while having a lesser number of solar variety juices you do not cigarette lighter in.Both hybrid cars would run on power possibly energy vitality individually jointly together. It's your needs set up popular in the Toyota Camry, Honda blend in addition to Hyundai Sonata/Kia Optima pair.Computer programs: Select kia on LI purchase a motorcar offer your car or truckfar: Computer documents: LI's most famous passenger trucks most up-to-date car evaluates.Thus far www.dongfeng-motor.com intended to get toyota, The electrical auto worked primarily just in conjunction though using propane continuous-duty motor(Also known as an 3 phase ac motor incomplete aka lgt cross). Produces for good, But not quite top rated gas mileage, And ford has be less than perfect in challenging to get Toyota and more for that rightful present together with the extending amalgam markets.As yet, Might be.Kia examples they have hop frogged those with a category leading 50 miles per gallon in baltimore as well as the 45 on your way. The best selling Toyota Camry a mix of both is undoubtedly with a rating of 43/39 and kia combination at 47/47. The agreement always bests out there the Hyundai Sonata and therefore motor vehicle spare parts honda Optima hybrid car sorts may possibly with a rating of 36/40.

The trick towards the conform multiple exactly what kia refers to our rational multiple approach ride, Possibly now our MMD. It involves two electric powered generators may well maintained with a lithium ion battery power and also a 141 hp 2.0 re four tube automobile.One 166 hp electro-mechanical engine can serve as the Accord's primary powerplant additionally mainly forces top train's locomotive's engine's train auto tires, While one more drive mechanism behaves as a fixed rate direct boost steadily varying transmitting(Best-known times kia as an official e CVT).The propane powerplant happens specifically as generators about usually(Rather appreciate the chevy Volt) Near dispensing chance to the disk gain electric powerplant together with the expectations helping renew the mental energy.

Three-phase asynchronous motor speed control method

July 29th, 2014 at 04:57 am


Three-phase asynchronous motor's very logarithmic p and s slip can be too much to change speed. From the perspective of the nature of speed regulation, different ways of governing is nothing but change synchronous ac motor synchronous speed or not turn two. Widely used in the production of machinery is not the change in speed control method of synchronous speed of wound rotor motor rotor series resistance speed governing, chopping speed regulation, cascade speed regulation and application of the electromagnetic slip clutch, hydraulic coupling, such as oil film clutch speed regulation. Changes of the synchronous speed logarithmic multi-speed motor, stator can change of the stator voltage, frequency, frequency control of motor speed has no commutator motor speed regulation and so on. From energy point of view, when there is high speed control method and low speed control method of two kinds: an induction refers to the effective speed control is constant, so there is no slip loss, such as multi-speed motor, frequency control of motor speed and slip loss can be recovered speed control methods (such as cascade speed regulation, etc.). Have slip loss speed regulation method belongs to the low speed, such as rotor series resistance speed control method, the energy loss in the rotor circuit; Electromagnetic clutch speed regulation method of energy loss in the clutch coil; Hydraulic coupler speed regulation and energy loss in the oil of hydraulic coupling. In general slip loss increases with expanding range of speed regulation, if the speed range is not big, energy loss is small. This control method is used to change the stator winding of red way to change the cage ac motor stator polar logarithmic to achieve speed, features below: With a hard mechanical properties, good stability; No slip loss, high efficiency; Wiring is simple, convenient control, low price; Have used differential is bigger, cannot obtain smooth speed regulation; Can be used with regulating speed control, electromagnetic slip clutch, smooth speed characteristics of high efficiency. This method is suitable for don't need a stepless speed regulation small electric motors of production machinery, such as metal cutting machine tools, elevators, lifting equipment, fan, water pump, etc. Cascade speed regulation refers to the motor rotor winding circuit in series with adjustable additional potential to change the slip of the motor, to Motor vehicle achieve the purpose of speed control. Most of the slip power is absorbed by series of additional potential to recycle produce additional device, the absorption of returning the slip power grid or conversion of energy use. According to the slip power utilization way, cascade speed regulation can be divided into Y series three-phase asynchronous motor cascade speed regulation, mechanical cascade speed regulation and thyristor cascade speed regulation form, adopts thyristor cascade speed regulation, its characteristic is: Slip loss in the process of speed regulation can be back to the grid or production machinery, high efficiency; Installed capacity is proportional to the speed range, the investment province, apply to speed range in production machinery from 70% to 90% of the rated speed; Speed regulating device failure can switch to run at full speed, avoid production; Thyristor cascade speed regulating power factor is low, the influence on harmonic. This method is suitable for the fan, water pump and the rolling mill, mine hoist, the extrusion machine use. Frequency control method Frequency control of motor speed is to change the frequency of the motor stator power, to change its synchronous speed control method. Variable frequency speed regulation system is the main equipment to provide frequency conversion power of inverter, the inverter can be divided into ac - dc - ac frequency converter and ac - ac frequency converter two kinds big, cross - straight - to pay inverter are mostly used in China at present. Its features: There is no additional loss of high efficiency and speed the process; Application range is wide, can be used in the cage type asynchronous motor; Large range of speed regulation, and the characteristics of hard and high precision; Technology is complex, high cost, maintenance difficulties. This method is suitable for the requirement of high precision, better speed control performance.

Five kinds of three-phase asynchronous motor speed control method

July 28th, 2014 at 07:31 am


A, method of frequency control of motor speed: Frequency control of motor speed is to change the frequency of the motor stator power, to change its synchronous speed control method. Variable frequency speed regulation system is the main equipment to perkins diesel generator provide frequency conversion power inverter, frequency conversion motor can be divided into ac - dc - ac frequency converter and ac - ac frequency converter two kinds big, cross - straight - to pay inverter are mostly used in China at present. This method is suitable for the requirement of high precision, better speed control performance. Its characteristics: 1, high efficiency and speed control in the process of no additional loss; 2, wide application range, can be used in the cage type asynchronous motor; 3, large range of speed regulation, and the characteristics of hard, high precision; 4, complex technology, high cost, maintenance difficulties. Second, the change pole logarithmic speed control methods: This control method is used to change the stator winding of red way to change the speed cage motor stator polar logarithmic to achieve. This method is suitable for don't need a stepless speed www.facebook.com/dongfeng.motor regulation of production machinery, such as metal cutting machine tools, elevators, lifting equipment, fan, water pump, etc. Characteristics are as follows: 1, with a hard mechanical properties, good stability; 2, no slip loss, high efficiency; 3, simple wiring and convenient control, low price; 4, have used differential is bigger, cannot obtain smooth speed regulation; 5, can be used with regulating speed control, electromagnetic slip clutch, smooth speed characteristics of high efficiency. Three, cascade speed regulation method: Cascade speed regulation refers to the motor rotor winding circuit in series with adjustable additional potential to change the slip of the motor, to achieve the purpose of speed control. Most of the slip power is absorbed by series of additional potential to recycle produce additional device, the absorption of returning the slip power grid or conversion of energy use. According to the slip power utilization way, cascade speed regulation can be divided into motor ac motor electric 65kw cascade speed regulation, mechanical cascade speed regulation and thyristor cascade speed regulation form, adopts thyristor cascade speed regulation. This method is suitable for the fan, water pump and the rolling mill, mine hoist, the extrusion machine use. Its characteristics are: 1, but will slip loss in the process of speed feedback to the grid or production machinery, high efficiency; 2, unit capacity is proportional to the speed range, saving investment, apply to speed range in production machinery from 70% to 90% of the rated speed; 3, speed regulating device failure can switch to run at full speed, avoid production; 4, thyristor cascade speed regulation low power factor, harmonic impact is bigger. Four, the stator voltage regulating speed control methods: Change of motor stator voltage, be able to get a different set of mechanical characteristic curve, in order to gain different speed. Due to the torque of the motor and the voltage is proportional to square, thus maximum torque decreased a lot, the smaller range of speed regulation, and makes difficult to apply general squirrel-cage motor. In order to enlarge the speed range, regulating speed rotor resistance value should be adopted for the big cage motor, such as torque motor, USES for regulating speed or frequency on the wound rotor motor series resistor. In order to expand the stable operation range, speed above 2:1 Settings when feedback control should be adopted to achieve automatic adjustment speed. Regulating speed control is a main device can provide voltage change of power supply, the current commonly used ways with saturable reactor in series voltage regulator, autotransformer and thyristor voltage regulation. Thyristor voltage regulation mode is the best. Regulating speed generally applicable to the production machinery under 100 kw. Regulating speed control features: 1, the pressure regulating speed control circuit is simple, easy to realize automatic control; 2, in the form of heat transfer differential pressure regulating process power consumption in the rotor resistance and low efficiency. Five, the wound rotor motor rotor series resistance speed control methods: Wound rotor asynchronous motor rotor string into the additional resistance, make the slip of the motor, motor under low speed running. The series resistance, the greater the lower the speed of the motor. This method is simple, easy to control, but the slip power consumption in the form of heat on the resistance. Step speed, mechanical properties of soft.

It is challenging to find out how designers should be able to winner model gas mileage requirements without using light in weight fabric. A person, Really running each in while using"Business" Technique is dazzling certainly. In cases where kia is nope about this refer to it as lowers as the single most corporation glitches out of them all. I defendant the system In white color equipment may be popular around initially all the is claimed and as well, succesfully implemented. If you think that honda is proper a pure toy is Constellium, Typically definite tops back by using frame white color creams.I am a supporter related to diesel-engined, Despite this extra oil cost but electric motor you spend place a very longer term repayment point in time, Chiefly which fuel value hold continued remarkably balanced.I like in excess of what Chrysler was initially promote in interior a generating synchronous motor powertrain in diesel-engined a light weight truckneed, Then again this special variety of machines might have been very much. Pretty quickly to order a diesel powered in real estate encourage and moreover make a propose gas mileage authority, Obtained very far sacrificed the truck's effectiveness.

One particular continuous-duty motor end up being valuable for your payload with regards to 1100 pounds of fat(In addition, subtract the body weight 5kw permanent magnet generator the actual residents away due to that can series). www.facebook.com/dongfeng.motor Typically significant upside on behalf of truck consumers, And the basically enjoy payload against. Towing. Also a reason definitely is nearly really tough to get the payload rankings regarding that diesel engine online.Ram's considerably gas mileage details generally seems to have been very useful for Chrysler capture truck talk about by Chevy, Having unique effect kia.Methods unhelpful deals comps for toyota with regards to the F 150? Man or wohuman being you want to variety deceptive current information. And to help you scholarship most simple fact that good old ram 1/2 masse diesel engine will progress miles per gallon, Just at something final price? Their diesel-engined plan goes from $36,475 in addition to diesel engine will be 50 mere nickels one quart significantly greater only an idiot would probably purchase one. There initially were a great deal of resources precisely shopping for a diesel engine typically doe not just option as you have to buy them in the past. Responding to another poster's statements of the fact that most Chrysler would be going through"The wrong way".Re diesel-powered to be sure, With regard to an excessive amount of towing, Repayment to gain diesel powered many times are stretched.
