A gas station refueling equipment explosion-proof motor end cover pressure test tool

Abstract

The invention relates to the technical field of pressure-resistant testing of motor end caps, in particular to a tooling for pressure-resistant testing of explosion-proof motor end caps of gas station refueling equipment, including a base, a test bench, a pressing mechanism, a positioning mechanism and a water supply mechanism. The pressing mechanism adopted in the present invention can simultaneously fix a plurality of motor end covers on the placement platform, and the motor end covers placed on the placement platform are separated from the protective cover by a baffle, a partition, a heating rod, and the placement platform, so as to facilitate Multiple motor end caps are subjected to withstand voltage tests at the same time, which avoids the problem of low test efficiency caused by a single test, and also reduces the number of times to fix the motor end caps, thereby reducing the workload of the operator. When the cover is placed, the positioning mechanism is used to ensure the accuracy of the placement position of the motor end cover, which avoids the deviation of the test results caused by the inaccurate placement of the motor end cover.

Description

technical field [0001] The invention relates to the technical field of withstand voltage testing of motor end caps, in particular to a tool for withstand voltage testing of explosion-proof motor end caps for refueling equipment at gas stations. Background technique [0002] Explosion-proof motor is a kind of motor that can be used in flammable and explosive places. It does not generate electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. Among them, the fuel dispenser in the gas station refueling equipment is The explosion-proof motor is used as the driving motor, and the frame, end cover and junction box of the explosion-proof motor have high requirements for strength and thickness. These parts should be tested for withstand voltage before use, and can be assembled and used after passing the test. [0003] At present, when testing the withstand voltage of explosion-proof motor end caps, t...

AI Technical Summary

Problems solved by technology

[0004] However, there are the following problems in the process of the above-mentioned explosion-proof motor end cap withstand voltage test: 1. A single motor end cap is subjected to a withstand voltage test, resulting in low efficiency of the withstand voltage test of the motor end cap. It is necessary to fix the motor end cover when testing the cover, which increases the workload of the operator

[0005] 2. When the motor end cover is placed on the test bench for testing, it is easy to cause a gap between the motor end cover and the test bench due to the inaccurate placement of the motor end cover, resulting in inaccurate test results for the motor end cover
