Automatic cooling device for submersible sewage pump

Abstract

The invention discloses an automatic cooling device for a submersible sewage pump, and relates to the technical field of submersible sewage pumps. According to the technical scheme, the automatic cooling device comprises a three-way pipe mounted between a water outlet and a drain pipe of the submersible sewage pump, and two of three ports of the three-way pipe are separately connected with the water outlet and the drain pipe; a mounting pipe is connected to the other port of the three-way pipe, a connecting pipe is connected to the mounting pipe, and a spray head is connected to the end, awayfrom the mounting pipe, of the connecting pipe; and a switch used for controlling the spray head to spray water is arranged at the joint of the mounting pipe and the connecting pipe. By adoption of the automatic cooling device, the problems that part of the submersible sewage pump is exposed out of water due to the decrease of the water level in the place where the submersible sewage pump is used,and the dissipation speed of heat generated by the submersible sewage pump in the operation process is smaller than the heating speed of the submersible sewage pump are solved; and by mounting the automatic cooling device on the submersible sewage pump, the submersible sewage pump can be cooled more conveniently when working above water.

Description

technical field [0001] The invention relates to the technical field of submersible sewage pumps, in particular to a self-cooling device for submersible sewage pumps. Background technique [0002] The submersible sewage pump is a kind of pump product that connects the pump and the motor and submerges into the liquid at the same time. Compared with the general horizontal pump or vertical sewage pump, the submersible sewage pump obviously has the following advantages: 1. Compact structure, small footprint. The submersible sewage pump can be installed directly in the sewage tank because it works submerged in the liquid. There is no need to build a special pump room for installing pumps and motors, which can save a lot of land and infrastructure costs. 2. Easy installation and maintenance. Small submersible sewage pumps can be installed freely, and large submersible sewage pumps are generally equipped with automatic coupling devices for automatic installation, and installation ...

3. Long continuous operation time

[0005] However, there is a deficiency in the existing submersible sewage pumps when they are in use. The places where the submersible sewage pumps are used (such as pools, rivers, etc.) sometimes cause part of the submersible sewage pumps to emerge from the water due to the drop in water level, and when the submersible sewage pumps continue to During operation, the submersible sewage pump itself will generate a certain amount of heat, and the speed of this heat is lower than the speed of heat generation, so when the heat reaches a certain level, it may cause burns to the components inside the submersible sewage pump
