Q:What is the difference between centrifugal pump and self suction pump? Which is better?

In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.

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:How many kilograms of water pump are there in the automatic washing machine on the market?

High pressure pump pressure can reach 4--8kg, flow 5 liters, work current 4 or so.

Q:If the calculation of the required pump flow is 45, lift 110, and the actual pump flow 100, head 125, what will happen in operation? Can I use it properly?

The air pump.The pump itself is mechanical failure.The pump outlet valve core off.Low voltage power.

Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?

Rated flow refers to the flow under the rated speed and rated pressure input to the motor.Due to leakage loss, the actual flow of the input motor must be greater than its theoretical flow. Actual flow of motor (i.e. inlet flow) leakage flow = theoretical flow of the motor.

Q:What does "efficiency" mean in a water pump catalog?

General pump efficiency is 60% ~ 85%. high efficiency of the pump, indicating the same work, the pump consumes the lowest energy, and vice versa

Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?

(1) pump connected outside pipes, containers, pipes, joints and other leakage test instrument, large leakage, rotary gas plug exhaust sound big, and the gas and oil mist discharge, should find leakage cancellation.(2) the assembly of rubber of intake pipe is not proper, damage or aging should be adjusted or replaced.(3) plug hole, the vacuum degree can be decreased, put the oil, remove the tank, loosen the nozzle plate, pull out the oil inlet nozzle, dredge oil hole, try not to use cotton wipe parts.(4) the vacuum system has serious pollution, including containers, pipes and so on. It should be cleaned.(5) the spring of the vane is broken and should be adjusted.

Q:How does the centrifugal pump pump and cut the pump?

Turn on the motor, observe the motor current, turn from high to low, observe the pump outlet pressure, and the pressure rise;Slowly open the outlet valve, so that the pressure drop slowly, the current slowly rising to the stable, the outlet valve to the maximum;Check the pump operation, stuffing box leakage, current, whether or not the rated current, motor, bearing temperature is normal, whether or not abnormal sound.

Q:What is the pumping property of concrete?

Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement
