How to troubleshoot insufficient exhaust volume?
Answer: 1. The air demand is too large. Check whether the gas equipment and the compressor exhaust volume are suitable.
- High-pressure air leaks. Check the air supply pipeline and valves to see if there are any leaks.
- The air filter is clogged. Check whether the instrument displays a maintenance signal and replace the filter element if necessary.
- The oil and gas separator filter element is clogged. Replace the oil separator filter element, oil filter element and oil.
- The pressure regulating valve is out of adjustment or damaged. Adjust the pressure regulator.
- The diesel engine speed is too low, adjust the speed, or check the diesel engine fuel filter.
- If the compressor rotor is worn, please ask service personnel to check it.
- The intake valve is not opened enough, check the control pipeline.
How to troubleshoot insufficient air supply pressure?
Answer: 1. The air demand is too large. Check whether the gas equipment and the compressor displacement are suitable.
- The air filter is clogged. Check whether the instrument displays a maintenance signal and replace the filter element if necessary.
- High-pressure air leaks. Check the air supply pipeline and valves to see if there are any leaks.
- The pressure regulating valve is out of adjustment or damaged, adjust or replace it (spare parts are available).
How to troubleshoot compressor overheating?
Answer: 1. The oil level in the oil barrel is too low. Refuel and check for leaks.
- The oil cooler is too dirty or blocked. Clean the cooler core fins.
- The fan belt is loose or damaged. Adjust the tensioner or replace the belt.
- The thermal element of the temperature control valve fails. Replace the thermal element.
- The oil pipe from the temperature control valve to the machine head is blocked. Clear the oil pipe.
- The main oil inlet joint of the machine head is clogged. Clear the joint.
- The oil filter is clogged, replace the filter element.
- The secondary oil return pipe is blocked. Clean the filter and orifice of the oil return pipe.
- Hot air refluxes. Move the machine and change direction to avoid reflux.
- The ambient temperature is too high, improve the ventilation environment.
How to check if there is oil in the air filter?
Answer: 1. Without unloading, the machine will shut down directly under high pressure. Please unload and then shut down after the pressure drops below 4bar. 2. The intake valve sealing ring is damaged, replace the intake valve.
How to troubleshoot excessive compressor oil consumption?
Answer: 1. The secondary oil return pipeline is blocked. Clean the oil return check valve and oil return pipe.
- If the lubrication system leaks, check the pipelines, joints and system components, and repair or replace them.
- The oil and gas separator filter element is damaged, replace the filter element.
- The system pressure is too low, check the minimum pressure valve and the muffler orifice.
- If there is too much oil, drain some lubricating oil.
- There is too much condensation water, drain the condensation water.
How to troubleshoot if the pressure is too high or the safety valve is open?
Answer: 1. The pressure setting of the pressure regulating valve is too high. Adjust the pressure setting.
- The overpressure vent valve is faulty, clean or replace it.
- Control air pipe leakage and check the control pipeline.
- The intake valve cannot be closed (stuck), maintain or replace the intake valve.
- The control system is blocked, check the control pipeline.
- The pressure regulating valve is out of adjustment or damaged, adjust or replace it (spare parts are available).
- The safety valve fails and needs to be replaced.
