According to the type of waste water, the building drainage system can be divided into three categories:
1. Living drainage system
2. Industrial waste water drainage system
3. Storm water drainage system
The diameter of the suction pipe of the pneumatic diaphragm pump shall not be less than the diameter of the inlet end of the pump, such as the diameter of the suction pipe is better than that of the pump inlet.
Self priming pump is a special kind of vane pump. Compared with the vane pump which do not need to install the valve, do not need irrigation before the start, can automatically discharge the air inlet pipe, the water absorption characteristics of the.
The replacement of the pump material due to excessive loss of operation of traditional material pump, improve the pump efficiency pump replacement material used in western countries, including the United States the Simms composite effective pump
High speed pipeline pump should be small flow, high lift occasions, can be used to transport a variety of corrosive. Viscosity of small -500mPa, s and liquid containing a certain concentration of solid particles.
The efficiency of centrifugal pump is the product of three kinds of efficiency, mechanical, volumetric and hydraulic. The efficiency of the pump group is the product of pump efficiency and motor efficiency.
Water pump is one of the most important equipment in the sewage treatment industry, and how to improve the performance of the sewage pump under the condition of ensuring the normal operation of the sewage pump?
The choice of deep water pump if you choose to model the lift is too high and the actual use of a large gap in the head, it will cause the motor over current, there will be heat and even burn the motor.
