Cooling Principle and Application Condition of Screw Air Compressor Cooler

- Jun 04, 2018-

Screw air compressor cooler is a device specially used to regulate the oil temperature of screw air compressor. It can be mainly divided into water-cooled cooler and air-cooled cooler. It is generally installed at the top of the air compressor. Or side, that is, on the compressed air line.


The working principle of the air-cooled model of the screw-type air compressor cooler is such that the cooling air is drawn in through an axial fan, blows through the cooling fins of the cooler, and performs heat exchange with the compressed gas and the lubricating oil. The effect of cooling. The maximum allowable ambient temperature for this cooling system is 45°C. If the system exceeds the limit, the system may cause interlocked parking.


The water-cooled screw air compressor cooler design must pay special attention to the cooling water temperature, to meet the compressor cooling water temperature reference temperature. In particular, the quality of cooling water must be in line with the general industrial water standards, and groundwater should be avoided as much as possible.


If the long-term oil temperature of the screw-type air compressor is too high and the oil quality is deteriorated, the air compressor oil will not achieve the lubrication effect, which will increase the wear of the equipment. In this case, the temperature of the oil needs to be reduced by the screw type compressor cooler. In order to obtain the desired cooling effect, certain conditions must also be met.


The number of lubricants for screw-type air compressor coolers is 13 engine oils in winter. In the summer, the engine oil is l9, and the oil tank oil is marked with 40 engine oil. When selecting the lubricating oil, if the conditions permit, good quality lubricating oil should be selected to ensure that the oil quality reduces carbon deposition.


At the same time, to maintain the smoothness of the screw-type air compressor cooler, the use of the cooler should be inspected regularly. It should be noted that the oil cooler should be cleaned in time to ensure the cooling effect of the oil cooler and the normal operation of the equipment. If the color of the oil in the oil window becomes thin and whitish, check the oil condition promptly. If the viscosity of the oil is reduced, it is necessary to replace the new oil or add some new oil in time. Usually, the new oil should be replaced within 3 to 6 months.
