Centrifugal pump with sand draining device

Abstract

The invention discloses a centrifugal pump with a sand draining device, and belongs to the field of centrifugal pumps. According to the scheme of the centrifugal pump with the sand draining device, sand draining work is realized through a capturing fiber cluster and a pebble layer, under the effect of high-frequency ultrasonic waves generated by a mounting groove, and gravel can leak to the bottoms of the pebble layer and the capturing fiber cluster from the upper half parts of the pebble layer and the capturing fiber cluster, is not easy to remain in the upper gap between the pebble layer andthe capturing fiber cluster, and is not easy to influence the sand draining effect of the capturing fiber cluster and the pebble layer; specifically, through the design of an elastic fiber body and the rifling of the capturing fiber cluster, the gravel can directly slide to the bottom layer of the elastic fiber body in cooperation with high-frequency vibration of the ultrasonic waves and does noteasily slide out of the elastic fiber body, sand draining work can be conducted on a water body about to enter the centrifugal pump, the gravel or other impurities are not easily mingled in the waterbody, and the normal service lifetime of the centrifugal pump is not easily influenced.

Description

technical field [0001] The invention relates to the field of centrifugal pumps, in particular to a centrifugal pump with an asphalt device. Background technique [0002] A centrifugal pump is a pump that transports liquid by the centrifugal force generated when the impeller rotates, and works by using the impeller to rotate to cause the water to undergo centrifugal motion. 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 pump casing. The pressure water pipeline flowing into the water pump. [0003] The basic structure of a centrifugal pump is composed of six parts: the impeller, the pump body, the pump shaft, the bearing, the sealing ring, and the stuffing box. The impeller is the core part of the centrifugal pump. The main fu...

Problems solved by technology

[0004] Water bodies in nature usually contain a lot of debris. For some rivers, a large amount of gravel and other debris are easily contained in the river. These debris are directly sucked into the pump body by the centrifugal pump and will be absorbed by the impeller under the action of the impeller. Directly generate large kinetic energy, causing irreversible damage to the impeller and sealing layer, affecting the overall sealing and impeller power of the centrifugal pump, and affecting the normal practical life of the centrifugal pump
