During use, excavator compressors may experience several malfunctions. Here are some common problems and their troubleshooting methods:
1. Compressor fails to start: Check the power supply, fuses, starter, etc., for proper function. Replace any damaged components immediately.
2. Compressor exhaust temperature is too high: Check the cooling system for proper operation, such as the radiator and fan. Check if the engine oil level is too high or too low, and if the oil is too dirty.
3. Compressor makes excessive noise: Check for foreign objects inside the compressor, such as screws or metal pieces. Check the wear of components such as pistons, cylinders, and crankshaft. Replace any severely worn parts immediately.
4. Compressor leaks oil: Check if oil seals, gaskets, and other seals are aged or damaged. Replace any damaged parts immediately. Check if the engine oil level is too high.
