Centrifugal pump

Abstract

The invention provides a centrifugal pump. The centrifugal pump comprises a pump body, an auxiliary ground inserting device, a water inlet unit and a water outlet unit, wherein the water inlet unit isinstalled on the side wall of the left end of the pump body, the water outlet unit is installed on the side wall of the right end of the pump body, and the auxiliary ground inserting device is installed at the lower end of the pump body through bolts. According to the centrifugal pump, the problems that when the centrifugal pump is placed in water or oil liquid, vibration is generated in the working process, so that the pump body is inclined and inclined, and then the work of the pump body is influenced can be solved; the problems that when the pump body is placed in the water or the oil liquid, a large number of fixed particles and the like existing in the pump body are adsorbed into the pump body, then normal operation of the pump body is influenced, and rotation of an impeller in the pump body is influenced after long-time use are solved; and the problems that when a water outlet of the pump body is connected with a guide pipe, a water guide pipe is prone to falling off due to thewater spraying pressure generated by the pump body, and then the work of the pump body is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a centrifugal pump. Background technique [0002] A pump is a machine that moves or pressurizes a fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport liquids such as water, oil, acid and alkali liquid, emulsion, suspoemulsion and liquid metal, and can also transport liquid, gas mixture and liquid containing suspended solids. Pumps can usually be divided into three categories according to their working principles: positive displacement pumps, dynamic pumps and other types of pumps. At present, the centrifugal pump has become the most widely used and the largest output pump in modern times. [0003] The current centrifugal pump is put into water or oil liquid during use; however, it has the following problems when it is placed in water or oil liquid directly; ...

AI Technical Summary

Problems solved by technology

[0003] The current centrifugal pump is put into water or oil liquid during use; however, it has the following problems when it is placed in water or oil liquid directly; the vibration of the centrifugal pump during work causes the pump body to tilt sideways, Then affect the work of the pump body; and the pump body is put into water or a large number of fixed particles in the oil are absorbed into the pump body and affect the normal operation of the pump body, and affect the rotation of the impeller inside the pump body after long-term use; And when the water outlet of the pump body is connected to the conduit, the water spray pressure generated by the pump body can easily cause the water conduit to fall off, affecting the work of the pump body
