Bedroom cold water pump

Abstract

The invention discloses a bedroom cold water pump comprising a motor part assembly, a volute assembly, a circulating cooling filter assembly and a cutting assembly. One part of water of a sewage outlet of a water outlet base of the volute assembly is introduced into a cooling sealing cavity in the motor part assembly through the circulating cooling filter assembly, sewage is used for circularly cooling a motor in a motor sealing cavity, energy utilization of resources is achieved, and the motor can be rapidly cooled. The cutting assembly is arranged in the volute assembly, arc tool slots are arranged on the two sides of the bottom end of a cutting tool bit in a mirror image mode, the rotary cutting efficiency of the two ends of the cutting tool bit can be improved through the arc tool slots, hard impurities can be rapidly cut, and the cutting effect is good. A thread protruding ring is in clamped connection with the interior of a ring-hook-shaped avoiding groove and is fixed through aconnection bolt, and connection firmness between the cutting tool bit and a cutting port ring part can be effectively ensured. By means of up-down matching arrangement of the cutting tool bit and thecutting port ring part, impurities are not likely to be clamped in the cutting assembly to caused faults and damage.

Description

technical field

[0001] The invention relates to the technical field of fluid mechanical equipment, in particular to a bedroom cold water pump. Background technique

[0002] With the development of cities, urban subways, hotels, restaurants and environmental protection requirements, horizontal cold water pumps are more and more widely used in my country, which directly drives the development of small integrated pump stations in China, and at the same time drives the supporting integrated pump station cylinders , valves, mechanical seals and automatic control industries. The structure design of the existing bedroom cold water pump is unreasonable, and the internal parts of the motor are usually burned and damaged due to overheating after use, which affects the overall operation. At present, to solve this problem, those skilled in the art have developed a method to pass oil through the oil injection pipeline and the oil outlet pipeline. Cool the motor, but there are many proble...
