Air exhausting device for motor hydrostatic test tank for deepwater submersible electric pump

Abstract

An air exhausting device for a motor hydrostatic test tank for a deepwater submersible electric pump comprises an end cover, a double-head bolt, a flange disc, nuts, a high pressure pipe, a stop valve, a lens cushion and a protection cover. The high pressure pipe is of a cylindrical structure, and the flange disc is arranged at the lower end. Mounting holes formed in an arrayed mode are formed inthe flange disc, the nuts comprise the first nut and the second nuts, and the double-head bolt is mounted in the mounting holes of the flange disc, the lower end is mounted on the end cover through threaded connection, the upper end is fixed to the flange disc through the first nut, the stop valve is arranged at the upper end of the high pressure pipe, the second nuts are arranged at the upper endand the lower end of the stop valve correspondingly, and the stop valve is fixed through the second nut at the upper end. The lens cushion is mounted at the joint of the high pressure pipe and the end cover, and the protection cover is mounted on the upper surface of the end cover. The air exhausting device overcomes the defects of the prior art, and can adapt to load frequency variation by adopting the lens cushion, sealing is durable and reliable, meanwhile, the structure is simple by adopting the stop valve, a sealed face is not liable to be worn and scratched, the sealing property is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of hydraulic test tanks, in particular to an exhaust device for motor hydraulic test tanks used in deep water submersible electric pumps. Background technique [0002] The hydraulic test tank is used for the hydraulic test of the mining submersible drainage equipment, to verify the diving depth, to ensure that the equipment can operate normally when the equipment is submerged to the specified depth, to analyze and verify the cause of the failure of the diving drainage equipment, and to exhaust the existing hydraulic test tank The sealing performance of the device is poor, the pressure resistance is weak, and the service life is short. Therefore, a motor hydraulic test tank exhaust device for deep water submersible electric pumps is designed. Contents of the invention [0003] The object of the present invention is to provide an exhaust device for a motor hydraulic test tank for a deep-water submersible ele...
