Screw air compressor vibration big how to return a responsibility

there are many reasons for the vibration of screw air compressor, of course, some people will have corresponding solutions!

1. The foundation design and construction quality are unqualified, resulting in insufficient rigidity and low vibration absorption capacity; or insufficient strength, and the anchor bolts cannot be fastened.

2. Improper placement of the shim during installation, or too many layers of shim and too large total thickness, resulting in poor contact and rigidity between the bottom surface of the fuselage, shim and the foundation surface

poor, causing anchor bolts to loosen.

3. The coaxiality error of the coupling between the motor and the transmission shaft is too large, resulting in large inertial force and moment of inertia, causing vibration.

4, pulley installation is not correct, the end face is not perpendicular to the axis, resulting in additional centrifugal force and centrifugal force torque, causing unit vibration.

5. The rolling bearing elements are worn, resulting in increased clearance, low movement accuracy and vibration.

6, airflow velocity and pressure fusion, triggering pulses, impact pipes, resulting in vibration.

To eliminate the vibration of air compressor generally from the following ways:

1, moving parts to school static balance and dynamic balance, otherwise it will cause congenital vibration factors.

2, air compressor and motor or diesel engine concentricity to correct.

The foundation of the air compressor should be constructed in strict accordance with the design drawings. There shall be no rigid connection between the foundation and any structure of the building.

4. Due to the vibration caused by airflow pulsation, the auxiliary equipment and pipelines must be provided with firm supports and cards. The cantilever random frames should be reinforced with brackets and plugged with shim iron.

5. The tightening force of the anchor screws of the machine should be consistent;

6. The frame (base) should have sufficient rigidity.
