Chemical environmental protection screw pump

Chemical environmental protection screw pumpIt is a rotary pump that relies on the volume change and movement of the meshing space formed by the pump body and screw to transport liquid or increase its pressure. Screw pumps are divided into single screw pumps, twin-screw pumps, and triple screw pumps according to the number of screws.

When the active screw rotates, it drives the engaged driven screw to rotate together, and the volume of the screw engagement space at one end of the suction chamber gradually increases, resulting in a decrease in pressure. The liquid enters the meshing space volume under the action of pressure difference. When the volume reaches its maximum and forms a sealed chamber, the liquid continuously moves axially in each sealed chamber until it is discharged from one end of the chamber. At this point, the volume of the screw engagement space at one end of the discharge chamber gradually decreases, and the liquid is discharged.

1) Wide range of pressure and flow. The pressure is about 3.4-340 kgf/cm2, and the flow rate can reach 18600 cm3/min;

2) The types and viscosity range of liquids transported are wide;

3) Due to the low inertia force of the rotating components inside the sludge screw pump, a high rotational speed can be used;

4) Good inhalation performance and self-priming ability;

5) Uniform and continuous flow, low vibration, and low noise;

6) Compared with other rotary pumps, it is less sensitive to incoming gases and pollutants;

7) The structure is solid and easy to install and maintain.

Chemical environmental protection screw pumpBy using a deceleration mechanism or a continuously variable speed mechanism to reduce the speed and keep it within a reasonable range of less than 300 revolutions per minute, the service life can be extended several times compared to high-speed screw pumps.
