From XiuShi, bending, losses, the vibration in the direction of crack and wear effect, to guide the direction of vibration damage is very sensitive, so, by introducing a special important compressor vibration frequency independent guidance (etc.) can measure the size, by the specific situation of the abnormal vibration frequency is not deducted. Due to find the values of the guidance or conditions of use, such as position sensor installation is different, so we must rely on the machine for each value analysis, comparative judgment standard.
Because even with guidance, either mild damage, abnormal and abnormal sound, so with sound, he knew that he found in the guidance of the operation of the global volume pressure and the size of a sound quality check, in order to prevent role before.
1. On the surface of the metal loss, add
Rolling bearing outer ring rolling body and, therefore, to add the effect of pulse cycle load cycles, thus produced
Contact stress. After the cycle, working pressure numerical value or the last, he added that in the normal production of fatigue. If the Supplier Of SKF Bearing http://www.fagbearings-hk.com/ load, thus can realize the fatigue. In addition, the installation, BuZheng compressor shaft direction also produces bending, add the phenomenon is normal. Lose the direction of fatigue, will also reduce the axial operation, organogenesis of accurate vibration and noise.
Guide 2 burns.
Burns's position, he added, on the other HuoSe scroll to the general. Burns is insufficient, the quality is a lubricating oil or does not conform to the requirement, and will be shut down direction assembly, etc.
3. Plastic deformation
Guidance and doug roller contact evenness of plastic deformation and pit direction. The reason for this is that a lot of goods or burden of correlation function, the impact pressure of working surface part of the materials, production of more restrictions
General purpose in the direction of rotation.
4. Bearing race bean
The causes of cracks in the circle of a bearing seat is powerful, the direction of foreign or loose bearing ring, including compressor, guide installation guide deformation and poor surface finish.
5. Maintains a broken
The reason is the insufficient lubrication, circle, broke the tilt, etc.
6. On the metal cage
The possible reasons are still tap or insufficient lubrication on the plane.
7. Serious wear ring doug
May be a circle of objects, in PaiHao lubricating oil is insufficient or inappropriate.
If can be directly measured oil orifice, temperature of the bearing outer ring is more suitable. In general, the temperature and comprehensive guide accelerator in the outside temperature can be predicted. Direction if appropriate lubrication, installation department, JiZhou rise to temperature and high temperature bearing, when it works, must stop take necessary precautions. Usually, face temperature rise gradually, as to reach a steady state after 1 to 2 hours. Guide SanReLiang machine normal temperature of the heat load capacity, and speed and different. When necessary, can use, Reagan in monitoring, temperature, and the correlation, realize the temperature exceeds GuiDingZhi automatic alarm, and prevent or stop the axis accident.
