The oil cooler in air separation equipment is a critical component that ensures stable lubricant temperature and the safe operation of core power units (such as compressors and expanders). During use, the following key aspects must be closely monitored to maintain its heat exchange efficiency and operational reliability.
First, strictly control oil temperature and operating conditions. Continuously monitor the lubricating oil temperature to ensure it remains stable within the optimal range of 40-55°C, preventing oil degradation and lubrication failure due to excessive temperatures or reduced fluidity from excessively low temperatures. Additionally, prohibit overloading to avoid overheating system failures caused by insufficient heat exchange capacity.
Second, ensure the supply of cooling medium. For water-cooled systems, maintain stable cooling water pressure and flow rate, strictly control water quality pH and hardness to prevent pipe scaling and corrosion; for air-cooled systems, ensure smooth airflow at the intake port without obstructions, and avoid the impact of high ambient temperatures on heat dissipation.
Furthermore, strictly prevent leakage and contamination. During routine inspections, focus on checking the sealing conditions. If oil or water leakage is detected, immediately stop the equipment and replace the seals to avoid coolant mixing with the oil and causing emulsification, or lubricant contaminating the cooling medium.
Finally, standardized maintenance and operation. Regularly clean the heat exchange surfaces and promptly clear pipeline blockages; strictly follow the startup sequence of "cooling medium first, then lubricating oil" and the reverse shutdown procedure. In case of sudden temperature rise or abnormal pressure, immediately stop the operation for inspection and prohibit running with faults.
