Precautions for the transmission of fuel gas by rotary joints

When installing hydraulic rotary joints , we should not neglect to find the direction of rotation in the joint. If it is installed upside down, it may cause the machine to burn. Therefore, at the beginning of installation, it is necessary to keep the hydraulic rotary joint and the connecting shaft concentric.
　　1. The fuel gas must flow from the sleeve side to the plug side, and the rotary joint uses external thread sealing material that controls the thread;
　　2. When installing the joint thread, do not exceed the maximum tightening torque to prevent damage;
　　3. The rotary joint should not exceed the maximum pressure Limit and temperature range to prevent the sealing material from wearing or leaking;
　　4. When using the rotary joint, it is forbidden to damage it by man, and do not use it in a place with dust or debris to prevent leakage;
　　5. Do not use the rotary joint in or near Use the rotary joint in the open flame;
　　6. When tempering, replace the new joint in time;
　　7. When installing the hose on the rotary joint, do not get oil in order to avoid natural fire. When installing the hose again, cut off the end of the hose by 3 cm.
　　Gas can be transported long distances through pipelines without polluting the environment. When using a rotary joint for transmission, the above seven points must be paid attention to to ensure the safety and efficiency of the transmission.
