What is the range of the vibration value of the air compressor host?

Generally, the vibration value and vibration speed of the motor will be measured when the motor is empty. The general vibration range of the motor is within 3 channels (that is, less than or equal to 0.03).

75kw air compressor standard vibration value: vibration intensity standard ISO2372(10-1KHz) range:

allowed: 4.5-7.0(mm/s)

comparison: 2.0-4.5(mm/s)

good: 0.45-1.8(mm/s)

----------------------------------------

there is no standard for the vibration standard of the screw air compressor, and there is no such test standard in the national standard of the screw air compressor.

screw compressor profile:

screw compressor is a working volume for rotary motion of the volumetric gas compression machinery. The compression of gas depends on the change of volume, and the change of volume is achieved by the rotary motion of a pair of rotors of the compressor in the casing.

The basic structure of the screw air compressor: in the body of the compressor, a pair of spiral rotors meshing with each other are arranged in parallel. Usually, the rotor with convex teeth outside the pitch circle is called male rotor or male screw. The rotor with concave teeth in the pitch circle is called the female rotor or the female screw. Generally, the male rotor is connected with the prime mover. The male rotor drives the female rotor to rotate the last pair of bearings on the rotor to achieve axial positioning and bear the compressor. Axial force. The cylindrical roller bearings at both ends of the rotor enable the rotor to achieve radial positioning and withstand the radial forces in the compressor. At both ends of the compressor body, orifices of a certain shape and size are respectively opened. One is for suction, called the intake port; the other is for exhaust, called the exhaust port.
