摘　　要：BE energy storage impact pneumatic trigger is a mechanical hand tool for disassembling bolts and nuts, which is widely used in petrochemical industry, electric power industry, transportation industry, shipbuilding industry, smelting industry, etc. This product can play a very prominent role in the overhaul of various industries, and a bolt and nut can be tightened or removed in a few seconds, thus greatly shortening the overhaul period of various lines, and it is also very safe and simple to use. As the power source of this product is compressed air, it is especially suitable for use in some explosion-proof places. It is one of the main components of the air cylinder impact pneumatic wrench, and its function is to drive the impeller inside the cylinder to rotate after compressed air enters the cylinder, thus generating rotational power. Its shell is made of aluminum alloy, and special steel material is used in the impact mechanism, which improves the strength of the drive shaft, strengthens the impact energy and output torque, and effectively alleviates the inherent defects of the machine such as easy jamming. This paper introduces the solutions to the problems of BE-30 impact pneumatic wrench cylinder cover crack, cylinder leakage, insufficient output torque and insufficient rotor speed, which cause the wrench to be weak in use. The related problems are solved by technical transformation, and the use effect is good, which accumulates valuable experience for repairing the problems of pneumatic wrench cylinder cover in the future.
