1. The definition of water pump From the pump manufacturing principle and technology, there is no clear water pump this definition, but in terms of water supply and drainage and environmental engineering, water pump is used to supply water pump, usually on the sewage treatment or Clean water after the clean water pool. Multi-use horizontal single-stage centrifugal pump. 2. Clean water rusty rust will be, but not necessarily the rust of water pump, water pressure is easy to rust a small pipe, booster after being washed out of the pump power of 100 watts should be enough , But the important thing is the head, if your floor is not high enough to lift the water up.When you buy look carefully, it is best to buy with a controlled, as long as a tap the pump will automatically open, shut down automatically stop, Easy to use 3. The difference between water pump and centrifugal pump Mainly water pump is the transmission medium is water, etc., the concept of centrifugal pumps and water pumps is not a category, one is the difference between the media, a structural structure. Some centrifugal pumps are clean water pumps, the difference is that they belong to a subordinate relationship between the water pump is a centrifugal pump classification, the classification of the pump is classified according to different impeller, centrifugal pump belongs to the vane pump, mainly through the motor The rotation of the shaft drives the media to tell the centrifugal motion in the impeller, so as to achieve pumping purpose! Clean water pumps are just a small subset of centrifugal pumps.
