The difference between the fresh water pump and water pump, sewage pump, and what is the difference between fresh water pump

Literally understanding, fresh water pump and water pump for pumping medium by different in terms of sewage pump is pumping water, sewage pump is pumping sewage. Fresh water pump and water pump belongs to the scope of a centrifugal pump, the structure and principle are centrifugal pump is the same. So where is the difference between fresh water water pump and water pump? Then mainly from the structure design, purpose, classification, type, etc, go ahead.

sewage pump and centrifugal pump type difference:

1, fresh water pump: belongs to a kind of centrifugal pump.

2, sewage pump, belongs to a kind of centrifugal pump impurity.

sewage pump and centrifugal pump classification difference:

1, fresh water pump: discrete fresh water pump, horizontal centrifugal pump, single-stage centrifugal pump, multi-stage centrifugal pump, centrifugal pumps, self-priming pumps.

2, sewage water pump, sewage pump can be divided into submerged sewage pump, pipes, sewage pump, submersible sewage pump, vertical sewage pump, corrosion resistance, acid sewage pumps, self-priming sewage pump pump.

fresh water pump and water pump design structure difference:

1, the flow design of difference: sewage pump has its own structure characteristics of sewage pump in order to avoid congestion, with large flow channel design is given priority to, such natural lead to efficiency is relatively low, so head generally is not high, and the fresh water pump flow is small, clearance is small, head is relatively high. Sewage pump, the efficiency is lower than the fresh water pump of the main reason is that their circulation road widening. Efficiency decline in the value of the main related to widen the extent of the sewage pump flow channel widening is to prevent blocking.

2, impeller design difference: sewage pump lift is not high, due to impurities in the water is more, the clearance between the impeller is bigger than fresh water pump. Sewage pump is prone to failure, and the general centrifugal pump is also similar, because smoke sewage, so the impeller wear faster, in order to prevent, sewage pump impeller design than the fresh water pump more simple, without retaining ring is equipped with jagged pieces, fabric, etc can be sundry break after pumping, and the fresh water pump impeller is give priority to in order to improve the work efficiency, its design is more complex, the efficiency will than sewage pump efficiency has improved significantly. Common centrifugal pump was designed to obtain the highest efficiency, that is to say, the fresh water pump of hydraulic structure parameters is to obtain the best combination of highest efficiency. The sewage pump, pump of this kind of special requirement its efficiency can not be more than the same period of the fresh water pump efficiency.

3, the pump body design difference: sewage pump pump pressurized water chamber is designed in the body, impurities from pressurized water chamber, pump flow channel open, when the impeller rotates wastewater will produce strong axial vortex effect, blowdown effect is remarkable. Directly connected, the fresh water pump pump body and motor transport is speak or similar water type liquid. Water pump room and suction chamber adopts hydraulic model designed, already beautiful with high efficiency.

fresh water pump and water pump USES the difference:

fresh water pump head high, sewage pump is low; Fresh water pump flow is relatively small, relatively large sewage pump; Sewage pump can transport clean water, fresh water pump can't conveying sewage.

1, the structure of the fresh water pump is a combination of motor and water pump, can transport water and physical and chemical properties of similar Yu Qingshui other liquid, used in industrial and urban water supply and drainage, pressurized water supply in high-rise building, garden sprinkler irrigation, fire pressurization, long-distance transmission, hvac refrigeration cycle, cold and hot water circulation pressurization in farmland irrigation, bathroom, etc, and form a complete set of equipment.

2, sewage pump: used for conveying is containing solid particles and the length of fiber impurities, can be widely used in the drainage engineering, studied the breeding, light industry, papermaking, textile, food, chemical industry, electric power, fiber, paste and mixed suspension chemical medium.

overall, fresh water pump and water pump is the main difference is their structure, the impeller and the flow field in the different design, as well as other parts of configuration, the causes of these different also because their usage and function of occasions are not the same. Precisely because they use situation is really good, on the other hand, so that they in the manufacturing structure is a significant difference between the two.
