Volume high-pressure water pump with slide block structure

Abstract

The invention provides a volume high-pressure water pump with a slide block structure. The volume high-pressure water pump with the slide block structure comprises a pump main body, a rotor, a left side plate, a right side plate and end covers. The volume high-pressure water pump with the slide block structure is characterized in that the pump main body is provided with a water inlet, a stator, awater outlet and a transmission shaft; the stator is fixedly arranged in the pump main body; a left side plate is mounted on the left side of the stator through a side plate movable mounting device; the left side plate is provided with a left side plate inner side surface and a left side plate outer side surface; a right side plate is mounted on the right side of the stator through the side platemovable mounting device; the right side plate is provided with a right side plate inner side surface and a right side plate outer side surface; the end covers are arranged on the outer side of the left side plate and the outer side of the right side plate; and the end covers are fixed on the pump main body through end cover connecting devices. As a rotor makes a peripheral motion, a bearing in therotor can be canceled to prevent shortening of the service life of the water pump due to water erosion of the bearing in the rotor.

Description

technical field [0001] The invention relates to a volumetric high-pressure water pump with a slider structure. Background technique [0002] At present, domestic water and fire-fighting water are supplied by water pumps, but the traditional centrifugal water pumps can no longer meet the needs of the times; because the floors are getting higher and higher, and the pressure of fire-fighting water is increasing, centrifugal water pumps can only be Relay water supply, so the positive displacement pump appeared; the positive displacement pump refers to a machine that can change the volume of the space and operate continuously in a closed space at the same time. The crescent-shaped space is divided into three parts A, B, and C. When the rotor rotates in one direction, the volume of the space A communicating with the water inlet increases gradually, and it is in the process of water intake. And the volume of the space C communicating with the water outlet is gradually shrinking, j...

AI Technical Summary

Problems solved by technology

At this time, the compressed liquid exceeds the hydraulic pressure outside the outlet, and the liquid flows out from the outlet, and the continuous operation of the pump achieves the purpose of continuous pumping; since the water supply to high-rise buildings in cities is almost used for a long time, the positive displacement pump needs to be repaired or replaced frequently at present. There are five problems: 1. The rotor is installed with a bearing structure, and the bearing is easily corroded by water, which makes the overall service life of the positive displacement pump shorter; 2. The rotor is eccentrically rotated, which affects the service life of the pump; Erosion and short service life; 4. When the displacement pump is running, there will be pulse force due to the high pressure water pumping, which will cause the displacement pump to vibrate very large, and it is necessary to install an airbag damper to operate normally, which increases the cost; 5. Due to the high pressure of the displacement pump The side leakage cannot be effectively solved during operation, resulting in low head
