Brief introduction of scroll pump

Scroll pump is a kind of vane pump. In terms of principle and structure, it is different from centrifugal and axial-flow pumps. It is called vortex pump because it sucks and discharges liquid by the action of vortex motion of liquid when the impeller rotates.

The main components of vortex pump include impeller, pump body, pump cover and their annular flow channel. Vortex pump impeller is different from centrifugal pump impeller. It is a disc with radial blades on the outer wheel. The liquid enters the flow channel through the suction pipe, obtains energy through the rotating impeller, and is transported to the discharge pipe to complete the working process of the pump.

The specific speed of scroll pump is usually between 6 and 50. It is a small flow and high head pump, which is suitable for conveying liquid or gas-liquid mixture with viscosity no more than 5 ° e, no solid particles and no impurities. Its flow range is 0.18 ~ 45 m3 / h, and the single-stage head can reach about 250 M.

Scroll pump is usually used in petroleum and chemical industry departments, especially in chemical fiber, medicine, chemical fertilizer and small boiler feed water.
