 PID is one of the most commonly used in the production of industrial control, PID control instrument is also one of the most commonly used in industrial control instrument, PID is suitable for the need for high accuracy measurement control system, according to the controlled automatic calculus of the optimal PID control single phase motor price parameters. PID parameters self-tuning controller can choose outside ANP gost motor a given or valve position control function. Can replace the servo amplifier direct drive actuator (e.g., valves, etc.). Outside a given PID or valve position controller can automatically follow the external generator set given value (or valve position feedback value) to control the output generator (analog control output or relay forward and inversion of control output). It can generator price realize automatic/manual switch without disturbances. Manual switch to automatic, will use the method integrating, so as to realize the smooth manual/automatic switching. Outside a given PID or valve position controller can display measured signal and valve position induction motor prices feedback signal at the same time.

1, each unit into Water pump the households must have built-in resident distribution box. Resident distribution box set power master switch, the switch can cut off phase ac induction motor line and neutral wire at the same time, and has disconnected. Each unit shall set electricity meter, electricity meter box should electric motors be stratified concentrated wall dark installed in public area. Resident distribution power always switch poles switch should be adopted in diesel generator set the oven, master switch capacity selection cannot too big, also cannot too small; To avoid and separate phenomenon at the same time tripping. Electricity meter box is usually stratified concentration is installed on the public channel, this is to facilitate squirrel cage induction motor the meter reading and management, wall is installed in order not to occupy the public channel. 2, a small set of (using the area shall be not less than 38 m2) electricity www.facebook.com/guohong.trading load design power for 4 kw; Medium (using area shall not be less than 49 m2) electricity load design power of 4. generator 6 kw; Great set (using the area of not less than 59 ac motors m2) electricity power load design for 6-8 kw.

Wire and cable, electrical should know some common sense

Must pay attention to the connection 3 phase induction motor is correct and reliable, and the secondary side are not allowed to answer the fuse or switch. Even if for some reason to dismantle the secondary side of the instrument or other devices, also must first to secondary side short circuit, then on again. Low voltage switch is lamination machine refers to under 1 kv isolating switch, circuit breaker, fuse and so on low voltage power distribution equipment controlled by load, must branch out, it is forbidden to more than a brake control and confusion. Low voltage rotor power distribution equipment and interlock of self-provided generator which should be reliable. It is strictly prohibited to bring their own power equipment and power grid parallel operation without permission. Low voltage power distribution equipment around before and after the operation and maintenance of channels should be laid on the insulation pad, piled up other items are strictly prohibited in the channel at the same time. Welding equipment: equipment first, followed by power supply. Dismantle rotor and stator devices: power supply, before equipment. Zero circuit: the first, followed by the line of fire. Down the line: after the first wire, scattered line. 

Low voltage fuse cannot as the motor overload protection. Fuse rated squirrel cage induction motor voltage must be greater than or equal www.facebook.com/dongfeng.motor to the working voltage of power distribution lines. Rated current of the fuse must be greater than rotor or equal to the rated current of the melt. Fuse breaking capacity must be greater than the possible maximum short-circuit current distribution circuit. Melt the selection of rated current, must meet the line normal working current and the starting current of the motor. For electric and lighting load short circuit protection, the rated lamination machine current of the melt is equal to or slightly greater electric generator than the rated current of the load. For single motor, melt rated current (1.5 2.5) or the motor rated permanent magnet generator current melt rated current in the power distribution system, and at a lower level shall coordinate, in order to realize the selective protection purposes. The next level should be smaller than at the next higher level. Ceramic plug fuse should be installed vertically, qualified fuse, must be used in other copper wire, etc. Replace the fuse. Spiral can fuse power into the line on the ac motors center of the base terminal, they can pick up the load for the shell of the screw terminals.

22, other ordinary socket: generally is to use wire of 2.5, according to room size commonly divided into 1 ~ 2 loop (refers to a flat, a big house or lamination more than two loop), generally small point of ac motor a loop, larger 2 circuits. First generator of 3 phase induction motor all be clear, we ac synchronous generator are currently equipped with multi-purpose 1.5 while the light line of wire, this from national specification is not right, but personally, I support this way. National specification is under 2.5 shall not be used as the main line, that is to say, it will take into the switch line 2.5, out of ac synchronous generator the line switch to the lamp with a can. However, the specification is considered the worst wiring way and calculation time without considering the energy-saving fluorescent lamp. Before we don't have to meet can lamp water pump price wattage is great, but now is energy-saving lamps, power is very small, 1.5 wire is far enough, can not waste is not wasted. Some families to shoot the light, of course, many, many crystalline light, this case 1.5 is not enough, so, particular case is particular analysis. Lamp line we recommend usually divided into 1 ~ 2 loop (except flat layer, the villa), 1 small points, large still two good, load is one aspect, the key is acmotor2.blogspot.com that squirrel cage induction motor if the evening lamp circuit is broken I failed, there is a lighting circuit.

Make motor electrically charged components cannot produce enough to cause explosion danger of spark and arc or dangerous temperature, or electrically charged components on these phenomena may be produced with the explosive mixture partition, make it can't touch each other or not with explosive danger degree (increased safety, ventilation, etc.). In all kinds of explosive dangerous environment, correctly selecting and all kinds of equipment form a complete set of explosion-proof motor is very important. Is a kind of explosion-proof electric motor can 3 phase induction motor be used in inflammable and explosive factory of a motor, the runtime does not produce sparks. Explosion-proof motor is mainly used in coal mine, petroleum, petrochemical and chemical industry. In addition, in the textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and other departments have also been widely used. As a major power equipment, explosion-proof electric motor is often used to drive pumps, fans, compressors and other mechanical transmission.
