The screw pump is a pump that uses the rotation of the helical blades to make the fluid rise in a spiral shape along the axial direction. It consists of a shaft, a spiral blade and a casing. When the motor drives the screw pump shaft to rotate, the fluid enters the blade and rises along the helical flow channel until it is transported out.
①Low speed (generally 20r/min~90r/min), small mechanical wear and no cavitation.
The screw pump is widely used in the transportation of water, wet sludge and flocculant liquid in sewage treatment plants because of its characteristics of variable amount transportation, strong self-priming ability, reversibility, and the ability to transport liquids containing solid particles. .Choosing a reasonable and reliable screw pump according to the actual needs of production can not only ensure the smooth progress of production, but also reduce the repair cost.
