What are the characteristics of vortex impurity pump compared with other types of vortex impurity pump?

2022-05-05 16:10:03

Compared with other types of vortex impurity pump, vortex impurity pump has the following characteristics:

(1) Vortex impurity pump is a high lift pump with simple structure. Compared with the centrifugal pump of the same size, its head is 2 ~ 4 times higher than that of the centrifugal pump; Compared with the positive displacement pump with the same head, its size is much smaller and its structure is much simpler.

(2) The efficiency of vortex pump is very low (due to the large impact loss of liquid in the flow channel), which is no more than 45%, usually 15% ~ 40%. Therefore, it is difficult to make a high-power pump. Judging from the vortex pump produced today, the power is generally no more than 30 kW. However, the efficiency of centrifugal pump with low specific speed is lower than it. Therefore, there are many occasions for vortex pump to replace centrifugal pump with low specific speed.

(3) Most vortex pumps have self-priming capacity, and some vortex pumps can also pump air or steam liquid mixture, which is beyond the power of general centrifugal pumps.

Specifically, for the closed impeller vortex pump, as long as a simple additional device is set, it can be self-priming. For the vortex pump with open impeller and closed channel, it has self-priming capacity and is usually used for air extraction; The vortex pump with open impeller and open flow channel is used to transport liquid and cannot be self-priming. Usually, the two pumps are assembled together. The former is used as a vacuum pump and the latter is used as a working pump. For example, the vortex pump of the tanker and the vortex pump of other structures.
