Abstract

The invention discloses a trolley-type fire extinguisher cylinder pressure alternating and blasting test device, which includes a fire extinguisher cylinder sample, an explosion-proof chamber, a measuring device, a pressurizing pipe and a pressure relief pipe. The fire extinguisher cylinder sample is placed in a closed In the explosion-proof room, there are measuring devices around the inner wall of the explosion-proof room. The measuring devices include a non-contact ultrasonic thickness gauge and a total station. The top of the fire extinguisher cylinder sample is connected to one end of the water inlet pipe, and the other end of the water inlet pipe passes through the explosion-proof chamber and the booster pipe. Connection, the booster pipe is connected to the bottom of the capacity cylinder through the booster pump, the water inlet pipe is connected to the pressure relief pipe, the pressure relief pipe is connected to the storage tank, the storage tank circulates the water back to the volume cylinder through the upper water pipe, and the outlet end of the upper water pipe is installed with ultrasonic water depth temperature tester. The present invention reduces manual operation and improves automation degree and test accuracy.

Description

technical field [0001] The invention relates to the technical field of fire protection product detection, in particular to a cart-type fire extinguisher cylinder pressure alternating and blasting test device. Background technique [0002] The cart-type fire extinguisher refers to a fire extinguisher equipped with wheels that can be pushed or pulled by one person to the fire site. Return to zero and cycle 6 times per minute. After a total of 1000 tests, the cylinder should be free of defects such as cracks and leaks. Then, the blasting test should be carried out. The value is not less than 2 times the test pressure and not less than 5MPa, the volumetric deformation rate when the cylinder is ruptured is not less than the relevant regulations, the rupture of the cylinder should not produce fragments, and the blasting hole should not occur on the head, longitudinal weld and fusion line. On the upper and girth welds, the blasting opening should be a plastic fracture, and the fra...
