Abstract

The invention discloses a sewage pump suitable for a sludge environment in the technical field of pumps. The sewage pump comprises a pump body, a pump shaft vertically penetrates through the top of the pump body, a filling cavity is arranged between the pump body and the pump shaft, a sealing filler is filled in the filling cavity, a pressing mechanism is arranged in the filling cavity, and the end, extending out of the pump body, of the pump shaft is connected with a coupler. By electrifying an electromagnet block, a check block can be attracted to the electromagnet block, and the situation that the check block moves downwards when the temperature of the pump shaft begins to drop, so that a vent hole is partially blocked again, and a pump shaft body cannot be well cooled continuously canbe avoided; and when the pump body stops working and the temperature of the pump shaft is reduced, the electromagnet block is powered off, and an air bag is not expanded due to heat, so that the checkblock can move downwards to block the vent hole, external water vapor can be prevented from entering the hollow pump shaft body, and the interior of the pump shaft body can be protected against corrosion.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a sewage pump suitable for sludge environments. Background technique [0002] Sewage pump is a kind of centrifugal impurity pump, which has various forms. Among them, when the vertical sewage pump works in sewage containing a large amount of sludge, the resistance and friction encountered by the pump shaft will be greater than when it is not in the sludge environment. , the friction will cause the temperature of the pump shaft to rise, and then the sealing packing will be deformed by heat and leakage will occur, and the pump shaft with a higher temperature will also accelerate the aging speed of the sewage pump. Therefore, we propose a sewage pump suitable for sludge environment Pump. Contents of the invention [0003] The purpose of the present invention is to provide a sewage pump suitable for sludge environment, to solve the problem that the vertical sewage pump proposed in t...
