High exhaust temperature of screw air compressor

Screw air compressor exhaust temperature is often high, what are the reasons for the high exhaust temperature, as follows:

lack of lubricating oil in 1;

the 2. oil filter is blocked;

3. oil cooler is blocked;

4. fuel cut-off valve core stuck;

the above four cases are due to lack of oil and lead to air compressor host exhaust temperature is too high.

5. the valve core fails, the lubricating oil is directly injected into the main engine of the air compressor without cooling through the cooler, causing the oil temperature to be too high;

6. it is caused by excessive friction force of the bearing of the main engine of the air compressor, it can be judged indirectly by observing the current value or measuring the vibration, or by carefully listening to the running sound of the bearing with a probe.

The above six cases are the main reasons for the high exhaust temperature of the air compressor. From this point of view, the maintenance and maintenance of the air compressor is necessary.
