Six reasons for high temperature failure of screw air compressor

The normal operating temperature of an air compressor is usually between 75°C and 95°C. High temperature alarm or shutdown; so what is the reason for the high temperature phenomenon of the air compressor? The air-cooled air compressor is taken as an example to introduce below.

Causes of high temperature of the air compressor 1. The cooler is blocked

First, determine if the cooler is clogged externally or internally. Internal blockage can be determined by checking the temperature difference between the inlet and outlet pipes of the cooler. If the temperature difference is too large, it is internally blocked. External blockages can be determined by looking at the amount of dust that has accumulated on the outside of the cooler.

Solution: Jammed inside. Need to find a professional air compressor repair service provider to deal with. Typically, you'll need to disassemble the cooler and soak both sides of the cooler and oil lines in a professional cleaner. After 20-30 minutes, clean it with a high-pressure water gun and install it after cleaning. Pay special attention to the oil in the oil circuit of the cooler, and don't forget to replenish the oil after installation. Blow out any blockages outside with low-pressure air to remove debris. If you can't blow it off, take it apart and clean it with a high-pressure water gun or put clogs inside to clean it.

The reason for the high temperature of the air compressor 2. Insufficient lubricating oil for the air compressor

Check the oil level glass on the oil and gas barrel. If the lube oil level is below the red line below, the lube oil is low.

Solution: Add an appropriate amount of lubricating oil between the upper and lower marks on the oil level glass.

The reason for the high temperature of the air compressor is three: the oil filter is clogged

Solution: Replace with a new oil filter.

Four reasons for the high temperature of the air compressor: The oil circulation pipeline of the oil and gas barrel is blocked.

Solution: Remove debris from oil and gas drums.

Five reasons for the high temperature of the air compressor: the cooling fan does not work

Normally, the cooling fans are turned on at 85°C and turned off below 75°C. If the temperature is too high, the cooling fan may not work and may be damaged, or the cooling fan contactor may be damaged.

Solution: Replace with new cooling fan, contactor or repair.

Solution: Replace the temperature sensor with a new one.

In addition to the above fault reasons, it is also necessary to check whether the temperature of the inverter module is too high. The solution is to clean the cooling part of the inverter (blow with low-pressure air). Even if the panel shows that the motor coil is hot, the solution is to blow the motor with low-pressure air the cooling part. In particular, it should be noted that the temperature of the air compressor operating environment is too high, and the temperature of the equipment will also rise. The solution is to use an exhaust fan to discharge the heat and reduce the ambient temperature.
