1. The small machine can be rotated by hand; to admit whether it can rotate smoothly. Check that the project has poor work due to foreign matter, scars and indentation; the equipment is not stable due to poor equipment; If the gap is too small, the equipment is wrong, the torque caused by the seal is too large, etc. If there is no abnormality, the power can be started. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2, large machinery can not be manually rotated; so the empty load immediately after the interception of the power; mechanical idling; see if there is oscillation, noise, rotating parts can touch, etc.; recognize no abnormalities; enter power work. Power work; Carrying low speed start; slowly progressing to the extra work of the specified conditions. Check the items in the test work; whether there is abnormal sound, TIMKEN imported bearing temperature change, smoothing agent leakage or discoloration, etc. If abnormality is found; Intermittent work; view the machine; remove the bearing if necessary.
Bearing temperature; generally can be estimated according to the external temperature of the bearing housing. However, the oil hole is used to directly measure the temperature of the outer ring of the bearing. The bearing temperature is gradually increased from the beginning of the work; the temperature is stable after 1~2 hours. If it is a bearing device Bad; temperature will rise sharply; abnormal high temperature occurs. The reasons are such as excessive smoothing agent, too small bearing clearance, poor equipment, excessive conflict of sealing equipment, etc. High-speed rotation; imported bearing layout, smooth selection of faults, etc. It is also the reason.
The transition sound of TIMKEN imported bearings is viewed with a stethoscope, etc.; there are strong metal noise, abnormal sounds, irregular sounds, etc. to clarify abnormalities. The reasons are poor smoothness, poor accuracy of shaft or bearing housing, bearing damage, foreign matter intrusion, etc.
