Q: Fire pump and shower pump flow head selection, high resolution.: Selection of flow head of fire pump and spray pump:1, the volume is greater than 5000 is less than 10000, the minimum water consumption of indoor fire hydrant is 10L/s

Q: Why can the centrifugal pump hold down the pressure?: Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. Vertical centrifugal pump is referred to as submerged pump, molten salt pump and submerged pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work.

Q: The main factors affecting the performance of centrifugal pumps: The specific speed is deduced by the law of hydraulic similarity, and the similarity between the hydraulic characteristics of centrifugal pumps is similar. In centrifugal pumps, the specific speed is often interpreted as: the pump works at the highest efficiency, generating a lift of LM, a flow rate of 0.075m, and the power consumed by the /s at 0. 735kW

Q: What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.: The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.

Q: Is the sewage pump the same as the mud pump?: No. the main functions are different:1, pump two main performance parameters is the displacement and pressure, displacement from a number of liters per minute, with the diameter and the drilling fluid requirements from the hole on the back end of the speed, the larger aperture, the greater the displacement

Q: How many square cables does the submersible pump for 7.5KW need?: I=P/ (1.732Ucos phi) =7.5/ (1.732X0.38X0.85) =13A (calculated according to three-phase city power, power factor 0.85).

Q: Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why: Centrifugal pump, and is a very common method of centrifugal pump, flow with the head (or pressure) increases, off a small valve resistance increases, the pump head should be increased, then the flow decreased, whereas open valve flow increase

Q: When the water pump is started, why should it start when the outlet valve is closed? Thank you: When the valve is closed, the flow of the pump is close to zero, the power of the pump is very small, which reduces the load that the motor starts to bear and has a protective effect on the motor. Therefore, the valve closed to start the pump.

Q: Metering pumps related matters: 1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal

Q: Significance of water pump model ISO50-160: According to different working principles can be divided into volumetric pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
