Abstract

The invention relates to the technical field of centrifugal pumps, in particular to an integrated rotor axial force self-balance centrifugal pump, a control method and a terminal so as to solve the problems that abrasion exists, fluid leaks and the service life of equipment is not long. The integrated rotor axial force self-balance centrifugal pump comprises a pump body, an impeller, a rotor, a pump shaft, a bearing and a spacer sleeve. The spacer sleeve covers the outer side of the rotor and the outer side of the impeller and is provided with a hollow boss stretching into a rotor cavity, and the pump shaft stretches into the hollow boss. The bearing is located in the cavity and arranged on the pump shaft in a sleeving manner and can slide along the pump shaft, and an overflowing groove is formed between the end portion, close to the impeller, of the bearing and the rotor. A first fluid loop and a second fluid loop are further arranged. When axial force points at the pump body, the first fluid loop is opened, and the second fluid loop is closed; and when axial force points at the spacer sleeve, the first fluid loop is closed, and the second fluid loop is opened. Thus, the impeller is in a self-balanced state all the time. According to the technical scheme, abrasion can be reduced, fluid leakage is reduced, and the service life of the centrifugal pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to an integrated rotor axial force self-balancing centrifugal pump, a control method and a terminal. Background technique [0002] A centrifugal pump is a pump that transports liquid by the centrifugal force generated when the impeller rotates. Centrifugal pumps are widely used in industrial production. The structure of the centrifugal pump in the prior art is briefly described as follows: it includes a pump body and an impeller, and the impeller is installed in the cavity of the pump body. The fluid enters the water inlet of the impeller from the water inlet of the pump body, flows out from the water outlet of the impeller to the pump cavity, and flows out through the water outlet of the pump body. [0003] For example, if figure 1 As shown, an impeller mouth ring 2' is set at the water inlet end of the impeller, a pump body mouth ring 1' is set on the inner wall of the...
