Causes of high temperature during the use of screw air compressor

The high temperature of air compressor is one of the common problems in the use of screw air compressor, especially for portable air compressor in outdoor work, which increases the possibility of such problems in hot summer. Generally speaking, the high temperature of air-cooled air compressor is caused by the following aspects:

high ambient temperature leads to high temperature of air-cooled air compressor, which will harm the air compressor from two aspects. A: The higher the temperature, the thinner the gas, resulting in a decrease in the working efficiency of the air compressor. The longer the load time of the air compressor, the more the load, the more the heat of the air compressor, and the higher the temperature of the air compressor.

Generally speaking, in the design of the air compressor, there is a design scheme of operating environment temperature (30-40 degrees). When the marine air compressor manufacturer operates at the operating ambient temperature of the design scheme, the high temperature is basically close to the maintenance temperature of the air compressor. If the ambient temperature of the air compressor is higher than the operating ambient temperature of the design scheme, the temperature of the screw air compressor will rise, causing the equipment to stop at high temperature.

The amount of oil in the air compressor is insufficient. The oil level of the cylinder can be checked. When the lubricating oil is stationary after shutdown and pressure relief, the oil level should be slightly higher than the high oil level mark H. During the operation of mechanical equipment, the oil level shall not be less than the low oil level mark. If the oil level is found to be insufficient or cannot be observed, stop the machine immediately to replenish.

Failure or abnormality of the stop valve. The oil blocking valve is generally a two-position two-position normally closed relay, which starts to open and terminates to close, so as to prevent the oil in the oil and gas barrel from continuously spraying into the engine and spraying from the air inlet when it terminates. If the parts are not opened during the loading process, the server will heat up quickly due to low oil, which will damage the equipment in severe cases.

Pay attention to the maintenance of screw air compressor and save a lot of money with small money. If conditions permit, it is suggested to invite professional maintenance personnel of air compressor manufacturers to carry out an air compressor maintenance to reduce unnecessary losses caused by shutdown of air compressor at high temperature.
