Q: Why should the pump be closed when the centrifugal pump is started?: Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.

Q: How many millimeters is the diameter of the water outlet of the four inch pump?: Here is a 4 inch inch, not rural, 1 inches =25.4 mm, 4 inches is approximately 100mm, with DN100 pipeline.

Q: Operating procedures for measuring pumps: 3, discharge pipeline unimpeded.4, the pipeline should meet the positive pressure head, that is, in high flow suction conditions work.5, check the direction of the pump, strictly prohibited reverse.6. Check the oil level in the crankcase compartment. For multi cylinder pumps, check that the oil level has reached the required level.7 、 pump motor static grounding is good, meet the requirements.

Q: What are the characteristics of a vertical multistage centrifugal pump?: Vertical multi-stage centrifugal pump is cast iron, the advantage is that the price is cheap, the disadvantage is bulky and power consumption.

Q: I want to know the concrete under 60 type pump performance, it is mainly the pump long spiral bored piles, such as the diameter of the pump, transportation distance, pumping height and so on, thank you!: HBT60.13.90S performance parametersParameter name unit HBT60.13.90SMaximum theoretical concrete conveying capacity m3/h 69/43Maximum pump outlet pressure Mpa 13/7

Q: What is the difference between the ground pump and the pump in the commercial concrete?: Day pump: the pump and pipe will be placed in a position on the site, the pipe in the air like the crane arm

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: Reciprocating pump is a positive displacement pump, the volume change of flow is the unit of time, constant flow speed constant, can not rely on increased resistance to change the flow resistance increase is only leaked, only small changes in flow.

Q: What is an industrial water pump?: The pump has the different uses, conveying different liquid medium, different flow rate, different lift range, therefore, its structure of course is not the same, the material is different, in general, can be divided into:1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system

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: What is the difference between centrifugal pump and self suction pump? Which is better?: If the centrifugal pump in full before the start of the shell of the gas, then start after the center of the impeller was thrown in the gas can not be large enough to form the vacuum, so that liquid in the bath can not be sucked, so the centrifugal pump to start before using foreign liquid in the pump housing space filling
