Which is a professional manufacturer of water pump

1. First, find out whether the motor burns the bearing (mechanical fault) or the coil (electrical fault). If it is the fault of burning coil, it is mainly caused by overcurrent, sometimes too high or too low voltage will also cause the coil to heat and short circuit, so check that the voltage when running is too different from the rated voltage.There may be several reasons for over-current short-circuiting: A. the equipment is overloaded to make the motor run for a long time at rated or over rated current. In particular, the starting current of the motor is 3-5 times that of the rated current. Therefore, we should try to avoid running with load or full load when starting the equipment (mainly depending on the matching allowance of rated current and normal operating current of motor). B, the motor works in a wet working environment. The insulation of the coils should be checked before the motor starts. The insulation requirements of different voltage grades are also different. May r...

1,Chilled water pump: a device that drives the circulation of water in a chilled water loop. The end of an air conditioning room (such as a fan coil unit, an air handling unit, etc.) requires cold water from the chiller. However, refrigerated water does not flow naturally due to the limitation of resistance, which requires the pump to drive the cooling water for circulation to achieve the purpose of heat transfer. 2,The cooling water pump in cooling water loop drive water device for circulating cooling water. As we know, take part in the refrigerant heat chiller, cooling tower and flows into the heat release. The cooling water pump is responsible for driving the cooling water circulating in the cooling tower and the unit closed loop shape. With the chilled water pump. 3,Feeding water pump: air conditioning water supply device, responsible for the treatment of soft water into the system. The commonly used pumps are horizontal centrifugal pumps and vertical centrifugal pumps, which can ...

These problems often occur when you work at regular work and debug the equipment： 1 . When the converter of the heat exchange station is opened , the pressure transmitter shall jump ; 2 . using frequency converter to control the water supply , the voltage transformer is used as a signal for collecting pressure , and the voltage transformer is interfered by the frequency converter ; 3 . When the frequency converter starts up the motor , the voltage change signal is unstable and the jitter is great ; 4 . The voltage transformer ( 4 – 20mA ) shall jump after the frequency converter is started , and the integrated thermal resistance ( 4 – 20mA ) nearby is not affected , and the signal line is not shielded . These phenomena are due to the interference of the frequency converter. Why does the inverter produce interference The inverter comprises a rectifying circuit and an inverter circuit , wherein the input AC power is converted into a DC voltage through a rectifying circuit and a wave loo...

1. Overload protection When the motor runs over the rated current for a long time under the overloaded fault, it will cause the motor to overheat, reduce the insulation and burn down. The protector calculates the thermal capacity of the motor according to the heating characteristics of the motor. The characteristics of different tripping levels corresponding to the protection of the motor by simulating the heating characteristics of the motor and the overload protection. 2 . Underload protection When the load of the motor is the pump type load , the motor no – load or under – load transfer is harmful , the protector provides under – load protection , and when the percentage of the average current of the three – phase and the rated current is lower than the set value , the protector shall operate within the action ( delay ) setting time or alarm within the alarm time . 3, blocking / blocking protection When the motor is starting or running, if the electric timing shaft is jammed be...
