The classification of the bearing seal and maintenance repair and exception handling

The classification of the bearing seal repair and maintenance and exception handling source: bearing | last updated: - 2020 08 - 04 the classification of the bearing seal bearing seal can be divided into two categories, own seal and seal. The so-called bearing with seal is made bearing itself into a sealing device. Such as bearing with dust cover, sealing ring, etc. This seal take up the space is small, easy installation and disassembly, cost is low. Alleged bearing and sealing device, it is inside the installation end cover manufacturing into a sealing device has a variety of performance. Bearing and seal is divided into the non-contact seal and contact seal. The non-contact seal is suitable for high speed and high temperature occasion, such as clearance type, labyrinth and gasket type different structure forms. Contact seal is suitable for the medium and low speed working conditions, commonly used have felt seal, cup sealing structure, etc. According to the bearing working condition and working environment requirement for sealing on the engineering design is often integrated use of various seal form, in order to achieve better sealing effect. Bearing maintenance and repair, and exception handling: as long as possible to keep the original function of bearing, the need for maintenance and repair, to prevent accidents, to ensure the reliability of operation, increase productivity and efficiency. Regular maintenance very good corresponding mechanical operation conditions of operating standards. It includes checking operating conditions, supplement or replace lubricating oil, remove on a regular basis. As maintenance project in the operation, the bearing rotation noise, vibration, temperature, lubrication condition and so on. For more information about it. Generally speaking, if used correctly, the bearing can be used to its fatigue life. But there will be a premature failure accident, will not tolerate usage. In contrast to the fatigue life, the early damage limit is called the use of quality failure or accident. Many of installation, use, lubrication and lead to don't pay attention to the invasion of foreign body from outside, study the heating effect of the shaft, the shell is not enough, and so on. The damage status of bearings, such as: roller bearings flange damaged, as the reason for considering, lubricating oil is insufficient, not suitable for oil and gas structure defects, the invasion of foreign body, installation error, bearing axis flexible music is too big, these reasons will overlap. Therefore, it is only through the investigation for bearing damage, can know the true reason of injury. However, if you know the conditions of use, bearing mechanical conditions of use, bearing structure, understand the situation before and after the accident combining bearing damage and check for several reasons, can prevent the similar accidents from happening again.
