Compressor unit lubricating oil station tank temperature
Thread Content
Currently, the oil temperature in the tank remains at around 70°C for extended periods of time, which is very detrimental to the quality of the oil; it’s as if the entire tank of oil is constantly exposed to high temperatures near 70°C. Conventional lubrication system designs keep the oil tank temperature at 40-50°C. Therefore, it is very meaningful to further improve the cooling effect of the lubrication system. To improve the lubrication performance of air compressors and extend the service life of lubricating oil. Do anyone have any technical improvement suggestions to lower the oil temperature in the fuel tank?
Methods: 1. Check whether the oil cooler at the outlet of the lubricating oil pump is functioning properly (e.g., whether the inlet and outlet valves for the cooling water are fully open, and whether the cooling water pressure is too low). 2. Recalculate the parameters related to the oil cooler at the outlet of the lubricating oil pump and increase its capacity. 3. Thirdly, consider that there may be issues with the lubricating oil system of the unit, and technical support from the manufacturer is required.
Connecting a dry gas to maintain positive pressure in the tank allows fumes to be expelled quickly! Suspect that your fuel tank is a confined space
Cooling water, as well as raising the oil pressure within a certain range
70 degrees, what about the bearing shell temperature? What is the effect of the oil cooler?
Installing a separate fuel tank cooling system can lower the temperature of the fuel in the tank.
1. Check the design parameters of the oil tank to determine whether it is a design issue (which should generally not be the case) or a equipment problem. As the original poster mentioned, the temperature usually does not exceed 50°C (in our air compressor, the oil temperature in the tank is below 60°C, and the temperature at the outlet of the oil cooler is below 50°C).
2. The oil tank should be equipped with an exhaust fan; check whether it is functioning properly.
3. Inspect the oil cooling system, including whether the temperature, pressure, and flow rate of the cooling water used in the heat exchanger are normal, as well as whether there is any blockage in the tubes of the heat exchanger (which are typically filled with cooling water)

If the tank temperature reaches 70, it’s no longer something that the oil cooler can address; check whether the compressor bearing temperatures are normal and whether the oil return is proper
The fuel tank is maintained at a slight negative pressure, and the oil fumes are expelled through an oil mist fan
The oil supply temperature is fine; it is controlled at 45°C through the oil cooler and bypass valve.
Adjusting the pressure using a self-acting PCV valve should provide some improvement, but it will not lower the oil return temperature much
