Centrifugal pump with anti-blocking function

Abstract

The invention provides a centrifugal pump with an anti-blocking function, and relates to the technical field of pumps. Two lower bearing seats are arranged on the left upper part of an installation plate, and are correspondingly hinged to the lower ends of second transmission rods, and upper transmission wheels are arranged at the upper ends of the two second transmission rods; an upper guide railseat is arranged on the right lower part of an upper plate body, and the upper transmission wheels are slidably arranged in the upper guide rail seat; two lower guide rail seats are arranged on the installation plate, lower transmission wheels are slidably arranged in the lower guide rail seats, and are connected with the lower guide rail seats through a transmission shaft, and first transmissionrods are arranged at the two ends of the transmission shaft; an upper bearing seat is arranged on an upper plate body, and the upper ends of the first transmission rods are hinged to the upper bearing seat; the center points of the first transmission rods are hinged to the center points of the second transmission rods; and a pump body is arranged on the upper plate body, and a filtering barrel isarranged at the water inlet of the pump body. According to the centrifugal pump, the adjustability of the device is improved, installation and disassembly of the device are convenient, and the maintenance of the pump body is convenient; the problem that the pump body is prone to being block is solved; and the safety and stability of the pump body using are improved, meanwhile the self-cleaning effect of the device is improved, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a centrifugal pump with an anti-blocking function. Background technique [0002] The centrifugal pump works by using the rotation of the impeller to make the water centrifugally move. It is mainly composed of the impeller, the pump body, the pump shaft, the bearing, the sealing ring and the stuffing box. Its main features include: compact structure, wide range of flow head, uniform flow, stable operation, small vibration, low equipment installation, maintenance and repair costs, etc. Before the centrifugal pump is started, the pump casing and the suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and the water to rotate at a high speed, and the water undergoes centrifugal motion and is thrown to the outer edge of the impeller, passing through the volute pump casing. The flow channel flows into the pressure water pipeli...
