1 Definition of Clean Water Pump
In terms of the manufacturing principle and process of pumps, there is no definition of a clean water pump However, in terms of water supply, drainage, and environmental engineering, a clean water pump is a water pump used for supplying clean water, usually placed in a clean water tank after sewage treatment or tap water purification. Horizontal single-stage centrifugal pumps are commonly used.
2 Rust on the clean water pump
Rust is possible, but it may not necessarily be the rust of the water pump. Pipelines with low water pressure are prone to scaling and rusting, and they may be flushed out after being pressurized A pump power of around 100 watts should be sufficient, but the most important thing is the head. If the head of your floor is not high enough, the water cannot come up Pay attention when buying, it's good to buy ones with self-control.
As soon as you turn on the faucet, the pump will automatically turn on, and when you turn it off, it will automatically stop. It's very convenient to use
3 The difference between a clean water pump and a centrifugal pump
The main purpose of a clean water pump is to transport media such as clean water. The concepts of centrifugal pump and clean water pump are not the same category, one is the difference in media, and the other is the structural structure. Some centrifugal pumps are also clean water pumps, but the difference is that they belong to a subordinate relationship. Clean water pumps belong to the classification of centrifugal pumps, and the classification of pumps is based on the different impellers. Centrifugal pumps belong to blade pumps, which mainly use the rotation of the pump shaft driven by the motor to make the medium move centrifugally in the impeller, thereby achieving the purpose of pumping! Clear water pumps are just a small subcategory of centrifugal pumps!
Sewage pumps belong to the scope of centrifugal pumps, and their structure and principle are the same as general centrifugal pumps. Ordinary water pumps are designed to achieve high efficiency, which means that the hydraulic structural parameters of the water pump are the optimal combination for achieving high efficiency. Pumps with special requirements such as sewage pumps cannot exceed the efficiency of clean water pumps during the same period. Sewage pumps also have their own structural characteristics.
The head of sewage pumps is not high, and due to the large amount of debris in the sewage, the clearance between the impellers is larger than that of clean water pumps. The faults that sewage pumps are prone to are similar to those of general centrifugal pumps, as the impeller wears out quickly due to the pumping of sewage.
The main reason why sewage pumps have lower efficiency than clean water pumps is that their flow channels have been widened. The decrease in efficiency is mainly related to the degree of widening. The widening of the sewage pump channel is to prevent blockage
The impeller of a sewage pump is simpler than that of a clean water pump, without a protective ring, so it won't hold onto dirty grass. There is also a serrated blade under the impeller that can be adjusted up and down, which can crush and extract thread ends and cloth pieces.
