Characteristics of spiral centrifugal pump

A key part of the spiral centrifugal pump is its unique spiral centrifugal impeller, which has both spiral section and centrifugal section. It combines the advantages of non clogging of the spiral pump of the traditional centrifugal pump, so it is called spiral centrifugal pump. The spiral centrifugal pump originated in Switzerland and is designed to help Peruvian fishing plants transport live fish from fishing boats. Relying on the non blocking and soft transportation characteristics of the spiral centrifugal impeller, the pump can transport live fish from the fishing net to the ship and then from the ship to the processing plant intact. With the increasing development and improvement of products, the application field of spiral centrifugal pump is gradually expanded. Compared with ordinary impurity pump and swirl pump, the structure of spiral centrifugal pump determines that it has the following characteristics:
1) No blockage, good performance
The large channel formed by the blade, coupled with the role of inlet guidance and spiral propulsion, can transport the liquid containing large particles and fiber materials, especially the long fiber objects can pass smoothly. The solid concentration transported is higher than that of other types of non clogging pumps. Compared with the traditional centrifugal impeller with similar outer diameter, the diameter can be greatly improved.
2) Soft conveying and good non-destructive performance
The solid-liquid two-phase fluid is gradually pushed forward under the action of balanced helical force, and there is no sudden change in the flow direction, so the flow is balanced. In the sludge treatment process, it is suitable for conveying sludge and can maintain the characteristics of sludge.

3) High efficiency and wide area
4) Flat power curve
5) Characteristic curve with steep drop
When the head changes, the flow changes little, which can ensure continuous and stable operation.
6) The suction performance of the pump is good
The pump blade extends forward to the suction port, so it can pump the gas containing medium. When a trace of gas is inhaled, the performance, vibration and noise of the pump basically do not change. When the gas content exceeds 40%, the pump can still operate despite intermittent vibration.
7) High solid content
