What are the precautions for using dimethyl ether compressor?

1. Check before starting: make sure that the appearance of the equipment is not damaged, the pipelines and valves are not leaked, and the electrical system and explosion-proof device are in good condition; Check the state of self-lubricating parts, and it is forbidden to fill the air cavity with ordinary lubricating oil; Ensure that the operation area is well ventilated, fire-fighting facilities are complete, and emergency passages are unblocked.

2. Operation monitoring: real-time monitoring of pressure, temperature and vibration parameters, with the exhaust temperature controlled at 80-120℃ and the pressure not exceeding the design value; Check the leakage regularly, and stop the machine immediately if it is abnormal; Adjust the load strictly according to the process requirements to avoid sudden rise and fall.

3. Shutdown and maintenance: gradually reduce the load before shutdown, and replace the system with nitrogen until the dimethyl ether concentration reaches the standard; Replace the seals regularly, check the anti-corrosion parts, and maintain the lubrication system; Long-term downtime needs to drain the accumulated liquid and do a good job in equipment protection.
