End suction pump with silencing effect

Abstract

The invention discloses an end suction pump with the silencing effect. The end suction pump comprises a base, a motor, a heat dissipation tile, a pump body, a water inlet, a water outlet, a rotation shaft and an impeller. The motor is fixedly arranged at one end of the upper surface of the base. The heat dissipation tile is fixedly arranged on the surface of the motor. The pump body is detachablyfixed to the other end of the upper surface of the base. The water inlet is fixedly formed in one side of the pump body. The water outlet is fixedly formed in the top of the pump body, and the impeller is movably arranged in a pump body inner cavity. Guided water is injected into the water tank through a water injection port, and the water outlet dismounting frequency can be reduced; meanwhile, through a check valve in the water inlet, the guided water adding frequency is reduced, and using is more convenient; a silencer can be used for lowering noise sent during rotation of the impeller in the pump body; meanwhile, a silencing cover can lower noise sent through a heat dissipation fan at one end of the motor, and noise generated during device usage can be effectively lowered; and the end suction pump is suitable for being widely popularized and used.

Description

technical field [0001] The invention relates to an end-suction pump, in particular to an end-suction pump with mute effect. Background technique [0002] End suction centrifugal pump is a kind of centrifugal pump. Same name: end suction pump, with back pumping structure, impeller, main shaft and bearings can be installed and replaced without removing the pump casing. Sturdy structure minimizes misalignment and deformation of water pipes. Horizontal end suction pump is a commonly used mechanical equipment, widely used in high-rise building water supply and drainage, fire protection, sprinkler irrigation, water treatment, food and other industries. The existing horizontal end-suction pump can operate under 50HZ or 60HZ 2-pole or 4-pole conditions with the assistance of additional equipment such as frequency converters. However, the power delivered by the same pump is about 14 times different under the two conditions of 50HZ 4 poles (1450RPM) and 60HZ 2 poles (3500RPM). [0...

AI Technical Summary

Problems solved by technology

[0003] Horizontal end-suction pumps with a single suspension structure have exposed many problems during use. During use, the outlet pipe needs to be removed frequently to add water, which is more troublesome to use. At the same time, it will generate huge noise during operation, which is not conducive to city ​​use
