Water pressure test device for junction box of explosion-proof motor

Abstract

The invention provides a water pressure test device for a junction box of an explosion-proof motor. The water pressure test device comprises a press plate, sealers, an end part upper press plate, an end part lower press plate, a connecting screw, a press block, a bolt and a nut, wherein the press plate is pressed between an internal pin hole and a power interface hole of the junction box; the sealers are respectively placed between explosion-proof surfaces of the junction box as well as between the upper surface of the junction box and the press plate; an end part compressing structure is composed of the end part upper press plate, the end part lower press plate, the connecting screw, the press block and the bolt so as to realize compressing of the explosion-proof surfaces. The water pressure test device provided by the invention has simple structure, is convenient to manufacture, is easy to mount and dismount, is particularly suitable for a water pressure test of the processed junction box of the explosion-proof motor, and has a significant action effect.

Description

Technical field [0001] The invention relates to an explosion-proof motor junction box, in particular to a water pressure test device for an explosion-proof motor junction box. Background technique [0002] The water pressure test device for the explosion-proof motor junction box is installed outside the explosion-proof motor junction box. It is mainly used for sealing and is used for the water pressure test of the explosion-proof motor junction box after installation. The conventional explosion-proof motor junction box hydraulic test device has the following two shortcomings: 1. The conventional explosion-proof motor junction box hydraulic test device can only be tested before the junction box is processed. For the explosion-proof motor junction box that needs mass production, the water pressure The test is extremely inconvenient and the manufacturing cycle is long. Second, the conventional explosion-proof motor junction box hydraulic test device is used. After the end flameproof...

AI Technical Summary

Problems solved by technology

The conventional explosion-proof motor junction box hydraulic test device has the following two disadvantages: 1. Using the conventional explosion-proof motor junction box hydraulic test device can only be tested before the junction box is processed. For the explosion-proof motor junction box that needs mass production, the water pressure The test is extremely inconvenient and the manufacturing cycle is long; 2. Using the conventional explosion-proof motor junction box hydraulic test device, after the end explosion-proof surface is sealed with a pressure plate, the sealing effect between the junction box cover and the junction box seat cannot be guaranteed
