Water leakage warning device for sewage draining self-priming pump

Abstract

The invention discloses a water leakage warning device for sewage draining self-priming pump. The device comprises a bearing body, a first framework oil seal and a second framework oil seal, wherein openings are formed in two ends of the bearing body; the first framework oil seal and the second framework oil seal are arranged in tandem and at an interval at the opening in one end of the bearing body, and the other end of the bearing body is connected to a bearing cover; the bearing body is provided with a groove which is positioned between the first framework oil seal and the second frameworkoil seal, and leaked water can be prevented from entering the second framework oil seal through the groove. According to the device, a device through which leaked water can leak out of the bearing body is mounted at the opening in one end of the bearing body, so that water is prevented from entering the bearing body to corrode the bearing body in case of leaking due to the damage of a mechanical seal; and the problem that a user extremely inconveniently operates, controls and debug due to the corrosion in the bearing body can be solved.

Description

technical field [0001] The invention relates to the field of pumps in general machinery, in particular to a water leakage warning device for a sewage self-priming pump. Background technique [0002] There are various types of pumps in the pump industry. The basic function of the pump is to pressurize or lift the floating body. The medium includes slag water, sewage, chemical liquid, slurry, petroleum and so on. Its basic structure includes impeller type and volume type. [0003] There is only one skeleton oil seal on the front side of the front bearing of the existing sewage self-priming pump bearing body. If the mechanical seal is damaged and the medium leaks from the mechanical seal, the medium will pass over the skeleton oil seal and enter the inner cavity of the bearing body, causing the bearing body to rust. Thus affecting the operation of the bearing, and this all occurs inside the pump body, which cannot be seen outside the pump body, which greatly prolongs the time ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the object of the present invention is to provide a water leakage warning device for a sewage self-priming pump. A device for leaking water to leak out of the bearing body is installed at the opening at one end of the bearing body to prevent water from entering when the mechanical seal is damaged. The bearing body is corroded inside the bearing body, which solves the problem of extremely inconvenient operation, control and adjustment brought to the user by the corrosion of the inside of the bearing body
