What causes the loud sound of the screw machine

There may be many reasons for the loud sound of the screw machine. The following are some possible reasons:

host imbalance: When the screw compressor is running, if the rotor of the host is unbalanced, vibration and noise will be generated. This may be due to rotor design or manufacturing problems, or rotor wear after a long period of use.

Bearing wear: The bearing of the screw machine may wear after long-term use, resulting in unstable operation and noise.

Poor gear meshing: If the gears in the screw machine are poorly meshed, they will also produce noise during operation. This may be due to the lack of accuracy of the gear, or the wear of the gear after long-term use.

The oil and gas separator is blocked: If the oil and gas separator is blocked, the internal pressure of the screw machine will increase, resulting in noise.

Loose fasteners: During the operation of the screw machine, if the fasteners (such as screws, nuts, etc.) are loose, noise will also be generated when the machine is running.

Motor problems: Abnormalities in the motor, such as damage to the motor bearing, short circuit of the internal coil of the motor, etc., may cause the noise of the screw machine to increase.

In order to solve the problem of loud sound of the screw machine, you can try the following methods:

regular maintenance and maintenance of the screw machine, timely replacement of worn parts, such as bearings, gears, etc.

Check and adjust the balance of the main engine to ensure its smooth operation.

Clean the oil and gas separator to ensure that it is unobstructed.

Check the fastening condition of the fasteners to ensure that they are firm and reliable.

Check and repair the motor to ensure its normal operation.

If the above methods still cannot solve the problem, it is recommended to contact professional maintenance personnel for inspection and repair.
