Q: What is the pump lift voltage? And how to suppress the pumping voltage rise?: The elevator is mainly used by the power grid through the rectifier, filter, inverter and other transmission to the motor. The motor in high speed when the brake suddenly, but the rotor of the motor with the load (production machinery) mechanical inertia, could not stop quickly, resulting in the back EMF (EU voltage) motor is in the state of power, the reverse voltage and torque original electric state torque instead, and the motor with brake strong torque, forcing the rotor to stop fast but usually AC-DC-AC converter is the main power AC/DC rectifier circuit is irreversible and therefore cannot go back to the grid, energy will be accumulated in the filter capacitor, produce pump voltage, this phenomenon of pump voltage converter has great destructive power.

Q: What are the important parameters of the pump?: Pump parametersFlow rate QFlow is the amount of liquid (volume or mass) that is pumped out in unit timeVolume flow is expressed in Q units: m3/s, m3/h, l/s, etc.

Q: Why can't the inlet of centrifugal pump be negative pressure?: Therefore, the centrifugal pump inlet pressure can be negative, and negative number, should be used to pump cavitation margin and liquid saturated steam pressure parameters to specific calculation. Sometimes, the liquid saturated steam conveying pressure is very high, such as the 9 m water column, then the minimum pressure of the pump inlet should be equal to 4+9=13 meters, the atmospheric pressure is higher than 3 meters, not only for negative pressure, even higher than the atmospheric pressure to work properly.

Q: Concrete pump 125 pipe wall thickness: Concrete pump, also called concrete pump, consists of pump body and pipe. The utility model relates to a machine for continuously conveying concrete along a pipeline by utilizing pressure, which is mainly used for building, bridges and tunnels

Q: Why can the centrifugal pump hold down the pressure?: The centrifugal pump can hold pressure because of the suction pipe in the pump at the entrance of a non-return valve (valve).

Q: Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?: Generally slightly lower than 0.4MPa, Zai 0.35Mpa or so, if the outlet is blocked, the outlet pressure will equal 0.4MPa

Q: Is vane pump good or gear pump good?: 1) the reversible design of gear pumps can also usually reverse, but reverse after the suction port change, and the pump safety valve does not work; leaf pump is generally not allowed to reverse. 3) the single acting vane pump can be designed to change the eccentric distance by moving the stator at the constant speed, so as to achieve the purpose of variable direction.

Q: What are the problems that should be paid attention to when using vacuum pumps?: What are the problems that should be paid attention to when using vacuum pumps?

Q: What are the main performance parameters of the pump?: The main performance parameters of the pump are:The energy obtained by pumping a unit weight of liquid through a pump. In H, the unit is m.

Q: Why is the submersible pump tripped on an electrical switch?There is no electrical leakage protection, directly connected to the circuit breaker, and when the switch on, the circuit breaker jumpedI checked the line is good, the pump did not break down, is not the water pump?: Calculate or refer to the water pump nameplate that the normal operating current, according to this data exchange switch.2) with 500V shaking table, measuring the cable, motor insulation is in line with the requirements
