It can also transport liquids, gaseous mixtures and liquids containing suspended solids. The technical parameters of water pump performance include flow rate, suction range, head, shaft power, water power and efficiency, etc.

According to different working principles can be divided into positive displacement pumps, vane pumps and other types. Positive displacement pump is to use the change of its working volume to transfer energy; Vane pump is the use of rotary vane and water interaction to transfer energy, centrifugal pump, axial flow pump and mixed flow pump types.

The working principle of

1, positive displacement pump: use the working chamber volume cycle change to transport liquid.

2, blade pump: the use of blade and liquid interaction to transport liquid.

A centrifugal pump

General characteristics of centrifugal pump

(1) the flow direction of water along the centrifugal pump is axial suction along the impeller, perpendicular to the axial outflow, that is, in and out of the flow direction of each other at 90°.

(2) because the centrifugal pump forms a vacuum suction by the impeller inlet, so before starting must be poured into the pump and suction pipe water diversion, or vacuum pump pumping, in order to exhaust air to form a vacuum, and the pump shell and suction pipe must be strictly sealed, no air leakage, otherwise formed a vacuum, also suction water.

(3) since it is impossible to form an absolute vacuum at the impeller inlet, the suction height of the centrifugal pump should not exceed 10 meters. With the loss of water flow along the suction line, the actual allowable installation height (the height of the pump axis from the suction surface) is much less than 10 meters. If the installation is too high, it will not absorb water; In addition, because the mountain area is lower than the atmospheric pressure of the plain, so the same pump in the mountain area, especially in the high mountain installation, the installation height should be reduced, otherwise the water can not be sucked.

Advantages

Structure advantages

Simple structure, small volume, light weight, large amount of oil. Cycloidal rotor pump system with internal and external rotor meshing structure, the number of teeth, compact structure size, without the help of other isolation elements can form a seal chamber, the number of its parts are small.
