The stable operation of the equipment is the basis of production, Cement Equipment vibration not only damage the life of the equipment, the reactive power consumption is also a direct loss of business efficiency. The same size, the same capacity of enterprises, but different benefits, Cement Equipment which is inseparable from the stable operation. So reduce vibration, reduce reactive power consumption, significant significance. With the progress of science and technology, vibration components have been widely used in the cement industry, Cement Equipment the cement equipment monitoring and stable operation has played a positive role, but also provides a basis for the analysis of vibration. In this paper, through the analysis of vibration characteristics, Cement Equipment describes the vibration identification and processing methods, and peer exchanges.

The vibration of the support is mainly due to the damage of the bearing, the lack of rigidity of the equipment base and the loosening. When the bearing inside the jacket and rolling body pitting off, accompanied by vibration issued by the sound continuous, stuffy and broken, there is a clear sense of pressure, Cement Equipment the vertical direction of vibration; bearing inner jacket or rolling body fracture, in the rolling body Through the cracks in the moment, the impact of vibration, issued a larger sound, broken crisp short, Cement Equipment crack radial vibration; if the foreign body into the bearing, not only caused vibration, but also issued a scream, if the foreign body stays in the raceway to form the cushion , The rolling body through the place when the vibration, Cement Equipment sound boring and a sense of resistance, the cushion of the radial vibration, if the foreign body with the bearing operation will be issued friction sound, hear the bearing friction, screams, should be maintained Frame failure; Cement Equipment bearing and shaft different heart, the axial vibration, the sound when the light weight, more regular; normal wear and tear of the bearing, if the clearance is too large, the vibration will increase significantly, the vibration to the vertical direction. For the sliding bearing, silent without vibration, but the shaft and tile gap is too large, Cement Equipment due to the eddy oil swirl, will produce vibration, vibration in the vertical direction, there is a situation, the rotation of the axial positioning is not good, back and forth Strings, struck tile skirt produce axial vibration. When the rigidity of the equipment base is insufficient, Cement Equipment the vibration amount of the equipment is large, Cement Equipment the vibration value and the direction are unstable. If the seat is loose, the vibration in the vertical direction increases when the degree of looseness has not affected the installation accuracy.

The power transmission of the cement industry is mainly driven by gears, belts, couplings and so on. Normal gear transmission, meshing sound is relatively uniform, vibration is relatively stable, but in the bearing, gear, shaft, key and other problems, the overlap coefficient decreases, the engagement accuracy is reduced, will produce shock vibration, noise. I plant a character gear reducer, there have been broken teeth accident, cut off part of the total length of about 40%, resulting in periodic sound and vibration, Cement Equipment until the replacement so far. Cement Equipment When the bearing is damaged, the gear is unstable and the impact is constant. The level of the spur gear and the vertical vibration are increased and the helical gear increases axially. When the key cutting or key is loose, the normal engagement occurs, the impact frequency is low, Instability, vibration in the vertical and horizontal direction increases; gear pitting, noise vibration increases, the vertical gear vibration to the vertical direction, Cement Equipment helical gear to the main axis; broken teeth when the impact of heavy, frequency and speed, Vertical vibration value is large; shaft when the gear ring sound, when the light weight comparison law, frequency and speed consistent, vibration to the horizontal direction is large. Belt vibration in the belt of the elastic, bearing damage caused by the typical vibration, the belt is too loose, causing vibration, speed instability, the belt jitter up and down, Cement Equipment issued a beating sound, vibration direction in the pulley connection; bearing Damage, in addition to the above characteristics, accompanied by abnormal bearing sound and vibration. Transmission is common and prominent vibration, Cement Equipment is the coupling, due to coaxial degree is not good, when the operation caused by disturbance, axial vibration.

Equipment parts of the interference, such as the reducer, Cement Equipment Roots blower has a number of operating parts inside, once the internal parts of the positioning failure, the operating gap changes, Cement Equipment between the running parts will be collision or friction interference, vibration, vibration direction and impact The same direction.
