When the screw air compressor oil cooler is in normal operation, when the temperature of the lubricating oil separated from the oil and gas separator exceeds 77 degrees, the thermal valve will open, so the oil cooler will start cooling the lubricating oil. The cooling oil can ensure the ability to participate in the heat exchange of the compressor host.
If the screw air compressor oil cooler fails to meet the requirements during the operation, when the oil temperature of the oil and gas separator is raised to 113 ℃, the air compressor will automatically alarm and shutdown. The equipment needs to ensure the oil cooler to maintain a good working state.
How to remove the internal oil dirt of the screw air compressor oil cooler
If the oil dirt is not very thick, the special cleaning agent can be used. Add the cleaning agent, run for 50 hours without stopping, then discharge the oil completely, replace the new oil, and then do the maintenance after 500 hours. If the oil dirt is serious, and cause the equipment can not run, the air-conditioner wing cleaning agent or appropriate concentration NaOH solution can be used for cleaning (Please pay attention to safety during operation!)
The maintenance of the screw air compressor oil cooler
Screw air compressor oil cooler needs to be cleaned in the use according to the environment, so that the compressor can work at the normal temperature. In order to ensure the machine has a long service life, when there is block caused by foreign mater, the compressor exhaust temperature will rise. Generally, the outside of the air-cooled cooler should be cleaned every 1500 hours.
1. The regular cleaning of the screw air compressor oil cooler will have many advantages. It can make the unit always work under the ideal working temperature, which will benefit the performance and life of the machine.
2. The cleaning solution can be used to remove the dirt, otherwise, when the dirt is thicker, the cleaning work is quite troublesome, which will need to remove the cooler, and use the mechanical method to complete the cleaning work.
