Do you know how to remove and install the rotary joint? The disassembly and assembly of many things is not simple, and the rotary joint is one of them. Today, I will tell you about the disassembly and assembly method of the rotary joint: When installing the rotary joint, you must face down, install the spring underneath, and use hydraulic pressure to support the spring and put on the ferrule. If there is no hydraulic equipment, you can use a stick of the same size. Press the spring to the position of the water inlet and insert a longer iron bar into the water inlet to reduce the chance of spring ejection and injury. After compressing the spring, put in the copper pad, flat pad, O-ring, tapered graphite and hollow bearing ferrule in sequence, so that the rotary joint is installed.
When we disassemble the rotary joint and clean up the impurities inside, some friends will be confused and don't know how to install it. The fixed bearing of the rotary joint is under the hollow shaft, and there is a semi-circular ferrule. Remove it with a caliper and hold the hollow shaft with your hand to reduce the chance of spring ejection and injury; after removing the bearing, there is a tapered graphite underneath. The seal is the main part of the seal. There is a glass-like hard film on the surface of the graphite ring. Be careful to remove it and place it with clean paper. Do not scratch the graphite surface, otherwise a small scratch will also cause it The joint is leaking; when the graphite is removed, the following are O-rings, flat washers, copper washers and springs in sequence. This will be fine. Customers and friends need to know that during installation or disassembly, improper operation or scratches or dust on the graphite seal will cause leakage during installation.
