[0002] In the production of photocuring coatings, pneumatic diaphragm pumps are used. Pneumatic diaphragm pumps are a type of pump that uses compressed air as a power source. The main feature of pneumatic diaphragm pumps is that they can handle a variety of complex liquids, including corrosive media, high-viscosity liquids, media containing solid particles, and flammable and explosive media. It has good self-priming performance and can absorb liquids at a lower suction range. It is suitable for extracting liquids from liquid storage tanks at low locations or far away from the source. The structure of the pneumatic diaphragm pump is simple, reliable, and easy to maintain. It will not be damaged even when there is no liquid supply, and is suitable for operation under interruption conditions. In addition, the pneumatic diaphragm pump is also waterproof and explosion-proof, and is very reliable in flammable and explosive environments. The common pneumatic diaphragm pumps on the market have poor sealing at the connection position, and leakage is not easy to detect. In addition, during the operation of the pneumatic diaphragm pump, slight vibration will be generated, and the vibration suppression effect is poor, which can easily lead to loosening of the fixing nut.
