Description

Centrifugal pump convenient to maintenance

Technical Field

The invention relates to the technical field of centrifugal pumps, in particular to a centrifugal pump convenient to maintain.

Background

The centrifugal pump is a pump for conveying a liquid by a centrifugal force generated when an impeller rotates, and operates by causing water to centrifugally move by the rotation of the impeller. Before the water pump is started, the pump shell and the water suction pipe are filled with water, then the motor is started, the pump shaft drives the impeller and the water to rotate at a high speed, the water is thrown to the outer edge of the impeller to be thrown into a water pressure pipeline of the water pump through a flow channel of the volute-shaped pump shell. However, existing centrifugal pumps are not convenient to maintain at present.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides a centrifugal pump convenient to maintain, and the specific technical scheme is as follows:

a centrifugal pump convenient for maintenance, which comprises a base, a motor, a rotating shaft, an impeller and a shell,

the motor is arranged on the base, one end of the rotating shaft is connected with the motor, the other end of the rotating shaft is connected with the impeller, the lower surface of the shell is connected with the base, and the shell is provided with a water inlet pipe and a water outlet pipe;

the casing can be opened along inlet tube or outlet pipe, the opening part corresponds the department along radial direction and passes through hinge connection's mode and connect, and opening part and opening correspond the department all be provided with the sealing member on the surface, inlet tube or outlet pipe outer wall on the cover have a sealing tube, guarantee the leakproofness of inlet tube or outlet pipe, open the casing, can install impeller and pivot and dismantle, conveniently maintain and the part replacement inside the centrifugal pump.

Further, the opening is fixedly connected together through bolts.

Furthermore, the sealing tube is provided with an opening corresponding to the bolt.

Furthermore, a bearing box is arranged outside the rotating shaft, the bearing box is connected with one end of the shell through a fixing frame, and the bearing box is used for protecting a bearing.

Furthermore, the sealing tube is made of elastic material, and is sleeved on the water inlet pipe or the water outlet pipe after the shell is closed, so as to play a role in further sealing and connecting.

Furthermore, the centrifugal pump outside be provided with filter screen panel, keep off impurity outside, prevent that large-scale solid from blockking up the pump body.

The invention has the beneficial effects that: the centrifugal pump is simple in structure and reasonable in design, the whole centrifugal pump can be split into multiple sections, maintenance is facilitated, maintenance difficulty is reduced, work efficiency is improved, and the centrifugal pump is convenient to disassemble and install and convenient to decompose and transport.
