Q:What is a water pump coupling device?: The automatic coupling device of the water pump coupling device has compact structure and small occupation area. The sump pump works because it is submergedThe utility model can be directly installed in a sewage pool, and no special pump house is needed to install a pump and a machine, thereby saving large amounts of land and infrastructure expenses

Q:What are the basic technical parameters of the pump?: The basic parameters of the pump, the basic parameters of the main performance parameters of pump are the following: first, water pump flow Q flow is the amount of liquid in the pump unit time delivery out (volume or quality). The volume of flow with Q that the unit is: m3/s, m3/h, l/s and so on. The quality of flow unit is expressed in Qm. T/h, kg/s and so on. The relationship between mass flow and volume flow is Qm= P Q density in P - liquid (kg/m3, t/m3), room temperature water P =1000kg/m3.

Q:Why can the centrifugal pump hold down the pressure?: 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:Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.: One possibility is the automatic type household booster pump used for a period of time, automatic failure phenomenon, it is mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging. Can be re used. But that's not why if your booster pump isn't working properly all the time.

Q:Excuse me, what is the water pump from the lotus root?: The utility model relates to a self coupling sewage pump, which is composed of a base, a self coupling frame, a guide rod, a guide rod, a support seat, etc., and the utility model does not need bolt connection

Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?: Centrifugal pumps require a vacuum to produce negative pressure, which allows atmospheric pressure to lift the water surfaceAxial flow pump impeller is thrust on water

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?: Submersible pump cable or motor insulation is damaged.3) motor water solution

Q:How to calculate the motor power of metering pump?: The total mechanical power and hydraulic power, divided by the overall efficiency of pump, and the pump head and the utilization rate of pump mechanical efficiency, and then multiplied by 1.1 times (API675), you can get a metering pump motor need more power.

Q:How many square cables does the submersible pump for 7.5KW need?: According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.

Q:Rules for operation of centrifugal pumps: 5, before you stop, you should gradually close the outlet valve, then turn off the power supply.6, with the check valve line, in ensuring the check valve intact, without closing the outlet valve, check the pump cavity, no air can be directly switched on.
