The three stages of physical wear characteristics of lifts升降机有形磨损的三个阶段分别的特征

    升降机在工作的时候会发生摩擦,只要发生就会有磨损,这些磨损会对升降机日后的使用造成影响,所以充分认识升降机有形磨损的几个阶段对于预防升降机磨损至关重要。下面就来看看升降机有形磨损的三个阶段分别的特征都是什么?

    作为机械设备,升降机在很多场合被使用,经过长期使用之后,升降机各部件之间相互摩擦,总会受到大大小小的磨损,长此以往,升降机就会遭到贬值。升降机上容易磨损的部件比较多,想升降机密封圈、轮胎、油缸、支杆、泵站等,都是升降机易磨损的部件,而升降机经过长期磨损之后,很容易产生故障,影响工作。升降机的磨损可以分为有形磨损和无形磨损,两者均能引起机械设备原始价值的贬低,下面我们就来说一下有形磨损吧。

有形磨损:

1、初期磨损阶段:新升降机设备或大修理后的升降机设备在早期故障期的磨损状态,磨损速度快,主要原因是零件加工粗糙表面在负载运转中的快速磨损,低可靠度零件在负载下的迅速失效,安装不良,操作人员对新使用设备部熟悉等。随着粗糙表面被磨平,失效零件被更换,安装经过磨合调整,操作者逐渐熟悉设备,升降机设备的磨损速度逐渐减小。

2、正常磨损阶段:磨损速度缓慢,升降机还能处于最佳技术状态。这时应注意维护保养,采用正确的操作技术和使用规程,加强点检,预防偶发故障恶劣化。这时应注意维护保养,尽量延长该阶段的使用时间。

3、剧烈磨损阶段。当主要零部件的磨损程度已经达到正常使用极限时,继续使用,磨损就会急剧上升,造成升降机设备精度、技术性能、作业效率明显下降,故障率急剧上升。升降机设备使用中应及时发现正常使用极限,及时进行预防修理,更换磨损修理,更换磨损零件,防止故障发生。

    磨损在使用中是不可避免的,重要的是懂得维护,这样可以有效减少磨损程度,例如:定期在升降机链接轴销之间打磨润滑油,减少部件之间的磨损程度;定期检查升降机滚轮、中间轴及轴承、油缸销轴及轴承,臂架轴销及轴承等有无磨损。

    因此,在处理升降机的磨损时,必须先了解自己升降机设备磨损的状态,再去选择一个更为经济的处理方法。升降机有形磨损的每一个阶段的特征都不一样,一旦发现之后要立即按照上述的方法进行处理,防患于未燃。

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.
Visible 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.
