Maintenance for Lubrication System of Water Cooled Chiller Plant

When the chiller is below 80 ℃ ~ 30 ℃ below zero in the running system, people pay more attention to refrigerator, frozen water cycle system and electric control system, so the lubrication system is often overlooked. However, this system is also very important to the chiller. The maintenance of the chiller is indispensable, now we are going to tell you something about it.

1. Observe the normal oil surface, oil temperature and oil pressure in the daily inspection.

2. Regularly check the oil quality according to the oil change index stipulated in the frozen lubricating oil, and replace or supplement the filtered new oil.

3. Pay attention to check and adjust the end face clearance of the oil pump in the middle and overhaul, and replace the pump when necessary. The end face clearance of the pump varies from 0.03 to 0.08mm. Please refer to the assembly technical requirements and factory regulations of the pump for concrete value.

4. Regularly replace or clean the filter core, pipeline, and crankcase.

The maintenance of the lubrication system of the chiller requires techniques, which mainly involves the performance of the compressor's main engine. It is recommended to be operated by professionals to avoid unnecessary losses.
