Q: Know flow and lift how to calculate the pump power?: The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.

Q: 5 floor water pressure is too low, what kind of water pump is better?: The location of the pump is too far away from the pumping pool, the suction of the pump is not enough, cavitation phenomenon, pumping water, this water pump manufacturers, the pump will be placed in a reasonable position

Q: Brief description of centrifugal pump on / off operation: First, the preparation before the start(1) carefully check the inlet and outlet pipe line, valve, flange and pressure gauge joint of the pump, whether the installation is safe, comply with the requirements, whether the flow is correct, whether the anchor bolt and other connecting parts are loose or not.(2) add lubricating oil to the bearing case, and the oil level is 2/3 of the gauge of the bearing box.

Q: Operating procedures for measuring pumps: First, preparation and inspection before starting1. Check to make sure that the drain line is equipped with a safety valve with the correct set pressure.2. Check the screws for the liquid end parts.

Q: Rules for operation of centrifugal pumps: 3, start the pump, wait until the speed reaches the normal speed, slowly open the outlet valve, observe the ammeter at the same time, and control the current in the rated current range of the motor.4, the operation requires smooth operation of water pumps, no abnormal noise, no pressure fluctuations. The abnormal situation should be stopped in time.

Q: What is the difference between centrifugal pump and positive displacement pump?: The centrifugal pump is to rely on high-speed rotation of the impeller to do work on the fluid. These two types of pumps are also the most widely used.

Q: What does centrifugal pump mean horizontally?: Centrifugal pump: centrifugal pump is a centrifugal force on the impeller rotates to transport liquid pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work. The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.

Q: Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?: Household automatic booster pump is not started by pressure, it is induced water pump, that is boiled water faucet

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: Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?: The centrifugal pump at a fixed speed, the head is fixed, adjust the outlet valve to adjust the diversion area
