What is the function of pump pressure tank in frequency conversion water supply equipment?

2019/10/11


The volume of the pressure tank determines the sleep time of the pump.
 
1. The amount of pressure tank determines that the water supply network is in a certain pressure range;
In the case of leakage flow (L / s), the size of the pressure tank determines the restart time of the pump. The larger the volume is, the longer the interval time is.
Therefore, choosing a larger pressure tank can prolong the sleep time of the pump.
 
2. Correctly understand the volume of pressure vessel.
Too large volume of pressure tank will increase capital investment, inconvenient maintenance and long inflation time.

Structure of centrifugal pump


2023-06-29

The basic components of a centrifugal pump are a high-speed rotating impeller and a fixed worm-shaped pump casing. Usually centrifugal pumps have a number of (usually 4-12) backward curved vane impeller fastened to the pump shaft, and with the pump shaft driven by the motor for high-speed rotation.

The working principle of centrifugal pump

After the centrifugal pump starts, the pump shaft will drive the impeller together for high-speed rotational movement, forcing the pre-filled liquid between the blades to rotate, under the action of inertia centrifugal force, the liquid from the center of the impeller to the periphery for radial movement.
