Embodiment Construction

[0014] In order to further understand the features and technical content of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. However, the accompanying drawings are only provided for reference and illustration and are not used to limit the present invention.

[0015] Such as figure 1 As shown, the hydraulic test device for the explosion-proof motor junction box of the present invention includes a pressure plate 1, a sealing gasket 2, an upper pressure plate 3, a lower pressure plate 4, a connecting screw 5, a pressure block 6, a bolt 7 and a nut 8. The pressure plate 1 is pressed between the inner lead hole (that is, the upper surface) of the junction box and the power interface hole (that is, the plane of the end of the base), and the pressure plate 1 has holes that match the junction box for connection, fastening, and sealing. The gasket 2 is placed between the explosion-proof surface 10 of the junction ...

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...
