It is important to fully understand the stages of physical wear of lifts in order to prevent the wear and tear of lifts. What are the three stages of physical wear and tear of the elevator?
As a mechanical equipment, the elevator is used in many occasions, after a long period of use, the elevator parts of the friction between each other, there will be large and small wear, a long time, the elevator will be devalued. Easy to wear parts on the lift more, like the lift seal ring, tires, cylinder, rod, pump station, are easy to wear parts of the lift, and lift after a long period of wear, it is easy to produce fault, affect the work. Elevator wear can be divided into tangible wear and intangible wear, both can cause the degradation of the original value of mechanical equipment, the following we have a physical wear.
Initial wear stage: the new elevator equipment or after the big repair elevator equipment in early failure period of wear condition, wear speed, the main reason is that parts processing rough surface in the load running rapid wear and tear, low reliability of parts under the load of failure quickly, installation, operation personnel familiar with new use of all equipment, etc. As the rough surface is worn out, the failed parts are replaced, and the installation is adjusted through running-in, the operator gradually gets familiar with the equipment, and the wear rate of the elevator equipment gradually decreases.
Normal wear stage: wear rate is slow, lift can be in the best technical condition. At this time should pay attention to maintenance, the use of correct operating techniques and procedures, strengthen the point inspection, prevent accidental fault deterioration. At this time should pay attention to maintenance, as far as possible to extend the period of use.
Severe wear phase. When the wear degree of the main parts has reached the limit of normal use, continue to use, wear will rise sharply, resulting in the elevator equipment precision, technical performance, operating efficiency significantly decreased, failure rate sharply increased. In the use of lift equipment, the normal operating limit shall be found out in time, and the preventive repair shall be carried out in time.
Wear in use is inevitable, it is important to know the maintenance, so as to effectively reduce the degree of wear, such as: regularly between the elevator link shaft pin polish lubricating oil, reduce the degree of wear between parts; Check regularly whether the roller, intermediate shaft and bearing, cylinder pin shaft and bearing, arm shaft pin and bearing are worn.
Therefore, when dealing with the wear and tear of lift equipment, it is necessary to first understand the wear and tear state of lift equipment, and then choose a more economical method. The physical wear of the lift is different in every stage. Once found, it should be treated according to the above method immediately to prevent fire.
