Explosion-proof performance test device and test method for explosion-proof permanent magnet electric roller

Abstract

The invention discloses an explosion-proof performance test device and test method for an explosion-proof permanent magnet electric roller. The test device comprises an explosion-proof test tank, a tension device, a built-in pressure measuring device and a signal protection device, the tension device, the built-in pressure measuring device, the signal protection device and the roller are arrangedin a closed explosion-proof test tank body; the tension device is arranged on an outer rotor of the explosion-proof roller to simulate the field stress condition; the built-in pressure measuring device is mounted in the electric roller, and the two ends are separately arranged; the signal protection device is used for tension signal monitoring. According to the invention, rated load and overload are applied to the shell of the explosion-proof permanent magnet electric roller, and the explosion-proof permanent magnet electric roller is respectively subjected to an internal ignition non-explosion-propagation test, so that the stress direction and the test method are determined. By simulating the internal ignition non-explosion-propagation test of the permanent magnet electric roller in the actual stress state, compared with a traditional no-load state test method, the method is more accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof testing, and specifically designs an explosion-proof performance testing device and testing method of an explosion-proof permanent magnet electric drum. Background technique [0002] The shaft of the traditional explosion-proof motor rotates, but the shell does not rotate. The shell and the web bear the torque and do not bear the radial external force. The existing method is mainly aimed at rotating equipment similar to traditional motors. The sensor is directly installed on the shell wall of the explosion-proof shell, and the internal explosive gas mixture is ignited in the static and rotating states respectively, and the explosion pressure is measured as a reference pressure. At the same time, the internal explosive gas is ignited under static and no-load conditions, and the internal ignition non-explosion test is carried out to evaluate its detonation performance. [0003] The existing...
