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

Abstract

The invention provides a centrifugal pump, comprising a pump body, an auxiliary ground insertion device, a water inlet unit and a water outlet unit; the left end side wall of the pump body is equipped with a water inlet unit, and the right end side wall of the pump body is installed with a water outlet unit, The lower end of the pump body is equipped with an auxiliary ground insertion device through bolts; the invention can solve the problem that the centrifugal pump is placed in water or in oil, and the vibration generated during the working process causes the pump body to tilt sideways, thereby affecting the work of the pump body; and the pump body A large number of fixed particles in the water or oil are absorbed into the pump body and affect the normal operation of the pump body. After long-term use, it affects the impeller rotation inside the pump body; The water spray pressure generated by the pump body can easily cause the aqueduct to fall off, affecting the work of the pump body and other problems.

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; ...
