Junction Box Of Oil Pump

The above junction box can be used in the case of flammable and explosive, but there are still some shortcomings: the top seal of the junction box does not have the hidden danger of water intruding into the box, and the cover plate needs to be opened to disassemble when the box is removed, and the operation is inconvenient.

Junction Box Of Oil Pump



Product Overview

  The locomotive transformer oil pump is a fully sealed pump used to force oil circulation in the traction transformer of the locomotive. The locomotive transformer oil pump has high requirements on the sealing performance, and the protection level of the oil pump casing is required to reach IP67.

   At present, the common method for the protection of the oil pump junction box is to use the junction box and the cover plate, and the studs are penetrated from the inside of the junction box, the top surface of the junction box is covered with a cover plate, and the cover plate is fastened with a nut.   The Chinese Patent Publication No. CN206259789U discloses an explosion-proof junction box for an oil pump, which comprises a cover and a box body. The cover is arranged on the box body, and a bolt mounting hole is arranged on the box body; the first bolt passes through the cover. The through hole is connected; the cover is connected with the box body 2; the right side of the box body is provided with a wiring hole, and the outer portion of the wiring hole protrudes outside the box body, and is integrally formed with the box body.

   The above junction box can be used in the case of flammable and explosive, but there are still some shortcomings: the top seal of the junction box does not have the hidden danger of water intruding into the box, and the cover plate needs to be opened to disassemble when the box is removed, and the operation is inconvenient.

   The junction box of the oil pump solves the technical problem that the top seal of the existing junction box is insufficient for the intrusion of water into the box, and the cover needs to be opened when the box is removed, and the operation is inconvenient. The junction box of the oil pump comprises a box body penetrating up and down, the bottom surface of the box body is provided with a plurality of mounting holes, and the top surface of the box body is provided with a plurality of mounting holes 2, and the outer side wall of the box body is provided with a hole for receiving the bolt The groove has an opening of the inner groove facing the outer side of the casing, and the inner groove is separated from the inner cavity of the casing, and the mounting hole 1 and the mounting hole 2 are both connected to the inner groove. The junction box of the oil pump improves the convenience of disassembly and assembly, and also avoids the accumulation of water and liquid.

  As shown in FIG. 1-4, the junction box of the oil pump includes a cast aluminum case 1 which is vertically penetrated, and the case 1 has a rectangular parallelepiped shape, and four mounting holes are arranged at four corners of the bottom surface of the case 1 in the circumferential direction. 2, the top surface of the casing 1 is provided with four mounting holes 2 corresponding to the mounting holes 2, and the outer side wall of the casing 1 is provided with four inner grooves 4 for accommodating bolts, and the inner groove The opening of the opening 4 faces the outer side of the casing 1, the inner groove 4 is isolated from the inner cavity of the casing 1, and the mounting hole 2 and the mounting hole 2 are in communication with the inner groove 4. The bottom end opening edge of the casing 1 is circumferentially opened with a sealing groove 5, the sealing groove 5 is annular, and the mounting hole 2 is located at the periphery of the sealing groove 5. The top open edge of the casing 1 is circumferentially opened with an annular sealing groove 2, and the mounting hole 2 is located at the periphery of the sealing groove 26. A seal ring 7 having a circular cross section is embedded in the seal groove 5 and the seal groove 2, and preferably, the seal ring 7 is an O-ring.
