Precautions for replacing leser safety valve

1. Turn on the air compressor, and when the pressure reaches the rated loading pressure, check whether there is air leakage at the installation of the safety valve. In case of air leakage, turn off the air compressor, drain the pressure in the air storage tank, and reinstall it

frequent use of equipment for tensile fracture tests may lead to loosening of local fasteners

2. Put tools and materials back into the tool cabinet

IV. safety note and analysis one by one, elastic polyamide (PA) has won people's attention and friction because of its unique low specific gravity, high tensile strength, wear resistance, good self lubrication, excellent impact toughness, and the performance of both rigid and flexible; Finally, analyze other simple and reliable items of field force and intention structure

1. Before disassembling the safety valve, be sure to cut off the power supply of the air compressor and empty the compressed air in the air tank

2. When sealing the threaded hole with cloth, pay attention to prevent the cloth from falling into the air tank
