Abstract

The invention discloses a self-priming centrifugal pump capable of handling gas-liquid mixed media, which includes an outer casing; a group of water inlet casings are fastened to the right side of the outer casing, and a group of water outlets are arranged on the top of the outer casing for the water inlet. The right side of the water shell is provided with a group of water inlets; the right end of the outer shell is provided with a set of outer shell water inlet connecting flanges, and the left end of the water inlet shell is fixedly connected with a set of water inlet shell connecting flanges; the left end of the outer shell There is a group of impeller bodies rotatingly connected to the side; the left end surface of the impeller body is coaxially fixedly connected with a group of impeller drive shafts; the inner part on the right side of the outer shell is fixedly connected with a group of piston cylinders; the inner circumference of the piston cylinders is arranged in a sliding manner and connected with Five sets of piston rods and piston chambers; a set of water inlet filter nets are crimped and connected inside the right side of the outer shell through the filter net pressure ring. The invention can deal with different media such as gas and liquid, has strong adaptability and self-priming ability, and can provide high head while ensuring sufficient flow.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a self-priming centrifugal pump capable of handling gas-liquid mixed media. Background technique [0002] A centrifugal pump refers to a pump that delivers liquid by the centrifugal force generated when the impeller rotates. The basic structure of the centrifugal pump is composed of six parts: the impeller, the pump body, the pump shaft, the bearing, the sealing ring, the stuffing box, and the centrifugal pump. Compact structure, uniform flow, stable operation, low vibration, low cost of equipment installation, maintenance and overhaul are widely loved by people. [0003] Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pum...
