The screw compressor makes a loud noise when it is just started.

Screw compressor at the start of the loud noise may be caused by a variety of reasons, the following are some possible reasons and solutions:

motor or transmission system failure: Motor or transmission system failure, such as bearing damage, gear wear or shaft shaking, may cause abnormal vibration or noise of the screw compressor. Damaged parts such as bearings or gears should be inspected and replaced.

Damage to the internal parts of the screw machine: If the screw, bearing and other internal parts are damaged, the screw machine will run unstable, resulting in abnormal vibration or noise. Damaged parts should be inspected regularly and replaced.

Improper installation of the screw machine: installation problems such as weak foundation and low levelness may also cause unstable operation of the screw compressor and abnormal vibration or noise. It should be ensured that the screw compressor is installed on a firm and horizontal foundation.

Poor use environment of the screw machine: environmental factors such as too high temperature, too low or too high humidity may also affect the normal operation of the screw compressor, resulting in abnormal vibration or noise. The use environment should be improved to ensure that it operates under suitable temperature and humidity conditions.

Lubrication problems: When the screw compressor is running, if the lubricating oil is insufficient or excessive, it may cause abnormal noise. It should be ensured that the amount of lubricating oil is moderate and regularly checked and replaced.

Seal failure: If the seal in the screw compressor fails, it may cause the internal pressure of the compressor to drop, causing vibration and noise. Failure seals should be checked and replaced periodically.

In order to reduce the noise when the screw compressor starts, the following measures can be taken:

regularly maintain and inspect the screw compressor to ensure that it is in good working condition.

Pay attention to the installation and use environment of the screw compressor to ensure its stability, level and appropriate temperature and humidity.

Add lubricating oil in strict accordance with the prescribed standards to avoid too much or too little.

If the screw compressor is found to have abnormal noise, it should be stopped in time to check and take corresponding measures.
