There may be many reasons for the slow speed of the screw air compressor, the following are some common reasons and corresponding solutions:
1. motor problem
- motor damage or lack of lubrication: If the motor of the screw air compressor is damaged or lacks lubrication, it will cause slow speed.
- Solution: Check whether the motor is working normally, if there is any fault, it needs to be replaced or repaired. At the same time, check the lubrication of the motor to ensure good lubrication.
2. driveline problems
- the gear box, timing belt, coupling and other parts are damaged or the clearance is too large: Damage or excessive clearance of these components will cause a decrease in transmission efficiency and slow down the speed.
- Solution: Check whether all parts of the transmission system are damaged. If there is any damage, replace or repair it. At the same time, pay attention to regularly check the clearance of these parts, and adjust the tightness in time.
3. rolling bearing damage
- rolling bearing failure: If the rolling bearing fails, it will cause the machine to rotate unsteadily and the speed will drop.
- Solution: Check whether the rolling bearing is damaged. If it is damaged, it should be replaced in time to ensure the stability of the machine rotation.
4. air system problems
- failure of gas inlet and outlet, cylinder block, synchronizer and other components: The failure of these components may also cause the speed to slow down.
- Solution: Check whether the various parts of the air system are faulty, if there is a fault, replace or repair it in time.
5. electrical problems
- circuit fuse blown or burned: A problem with the circuit fuse will cause the device to start slowly or fail to start.
- Solution: Check whether the circuit fuse is blown or burned. If there is any problem, replace it with a new fuse.
- Abnormal power supply voltage or wiring problem: Unstable power supply voltage, loose terminals or poor contact may also cause slow speed.
- Solution: Check whether the power supply voltage is normal and whether the connector is firm and reliable.
- Fault of relay, sensor and frequency converter: The failure of these electrical components may also affect the speed of the air compressor.
- Solution: Check whether the relay, sensor, inverter and other electrical components are working normally. If there is any problem, it should be replaced or repaired in time.
6. other factors
- air filter clogged: The clogging of the air filter will cause poor air intake and affect the speed of the air compressor.
- Solution: Clean or replace the air filter regularly to keep the air intake unblocked.
- Gas consumption increases or gas circuit system leaks: If the air circuit system leaks or the air consumption increases, it will cause the air compressor to have insufficient air supply and the speed will drop.
- Solution: Check whether the gas circuit system leaks, and repair it in time if there is any leakage. At the same time, coordinate the use of gas, to ensure that the air compressor supply sufficient.
7. maintenance
- inadequate regular maintenance: The screw air compressor needs regular maintenance, such as replacing lubricating oil, cleaning filter, filling grease, etc. If the maintenance is insufficient, it will cause the equipment performance to decrease and the speed to slow down.
- Solution: According to the requirements of the equipment manual, regular maintenance shall be carried out to ensure that the equipment is in good condition.
In summary, the reasons for the slow speed of the screw air compressor may involve many aspects, and it is necessary to investigate one by one and take corresponding solutions. If the problem is complicated or cannot be solved, it is recommended to contact professional maintenance personnel for maintenance.
