1. Stop using: If the rubber compensator bulges in the middle, stop using it immediately to prevent further damage.
2. Find out the reason: check the pressure, temperature and flow rate in the system to determine the specific reason of the bulge, which is excessive pressure, overheated medium or system failure.
3. Repair or replacement: according to the specific situation, you can choose to repair or replace the rubber compensator. It's not a big problem. You can try to fix it. If the problem is serious or beyond repair, a new rubber compensator needs to be replaced.
4. Check other parts: At the same time, check whether other related parts, such as pipe fittings and supports, are damaged or loose and need to be replaced or repaired in time.
5. Preventive measures: In order to avoid the recurrence of similar problems, it is recommended to check and maintain the rubber compensator regularly to ensure the normal operation of the system. In addition, according to the characteristics of the working environment, choose the appropriate rubber compensator and ensure that it can withstand the pressure and temperature changes in the system. Rubber compensator, also known as rubber joint or rubber expansion joint, is an elastic connector used in pipeline system, which consists of inner rubber or neoprene, reinforcing layer (reinforced with steel wire or fabric) and outer rubber.
