对于空气压缩机设备的执行元件,常需要很低的速度,例如每分钟移动几毫米甚至不到1mm或者每分钟几转的转动。此时,往往会出现明显的速度不均,断续分时动时停、一快一慢、一跳一停的现象,空压机这种现象成为爬行,空压机运行过程中就会出现类似的问题,属于低速平稳性的问题。
For the actuator of air compressor equipment, a very low speed is often required, such as moving a few millimeters or even less than 1mm per minute or rotating a few revolutions per minute. At this time, there is often obvious uneven speed, intermittent time-sharing, moving and stopping, fast and slow, and jumping and stopping. This phenomenon of the air compressor becomes crawling, and similar problems will occur during the operation of the air compressor, which belongs to the problem of low-speed stability.
对于空气压缩机来说,爬行将会对其造成很大的危害,因此要排除。但是同样是爬行,其故障现象是有区别的:有规律的爬行;有无规律的爬行;有的爬行无规律且振幅大;有的爬行在低的速度下产生。
For the air compressor, crawling will cause great harm to it, so it should be eliminated. But it is also crawling, and its fault phenomenon is different: crawling regularly; Regular crawling; Some crawl irregularly and have large amplitude; Some crawling occurs at low speeds.

如何来理解空气压缩机的爬行现象
How to understand the crawling phenomenon of air compressor
空气压缩机产生这些不同现象的爬行,其原因各有不同的侧重面:有些以机械方面的原因为主、有些以空压方面的原因为主、有些以油中进入空气的原因为主、有些以润滑不好的原因为主。维修人员要不断总结归纳,迅速查明产生爬行的原因,予以排除。
The reasons for the crawling of these different phenomena of air compressor have different emphases: some are mainly due to mechanical reasons, some are mainly due to air pressure, some are mainly due to the entry of air into oil, and some are mainly due to poor lubrication. Maintenance personnel shall constantly summarize and quickly find out the causes of crawling and eliminate them.
为了有用解决空气压缩机的爬行问题,需要解决运动部件的摩擦状态和机器运动的平衡性。而造成这方面出现问题的原因有很多,比如导轨精度差,导轨面严重扭曲;导轨面上有锈斑;导轨压板镶条调得过紧,导轨副材料动、静摩擦因数差异大;导轨刮研不好、点数不够,点子不均匀;导轨上开设的油槽不好,深度太浅,运行时已磨掉,所开油槽不均匀,油槽长度太短等等。
In order to effectively solve the crawling problem of air compressor, it is necessary to solve the friction state of moving parts and the balance of machine motion. There are many reasons for these problems, such as poor accuracy of the guide rail and serious distortion of the guide rail surface; There are rust spots on the guide rail surface; The insert strip of the guide rail pressing plate is adjusted too tightly, and the dynamic and static friction coefficients of the guide rail pair materials are greatly different; Poor scraping and grinding of guide rail, insufficient points and uneven points; The oil groove on the guide rail is not good, the depth is too shallow, it has been worn off during operation, the oil groove is uneven, the length of the oil groove is too short, etc.
除了空气压缩机的导轨不符合要求之外,还有机器上的空压缸的问题,比如空压缸轴心线与导轨不平行;缸体孔内拘捕段锈蚀和拉伤;空压缸体孔、活塞杆及活塞精度差;空压缸及安装精度差,活塞、活塞杆、缸体孔及油缸盖孔的同轴度差等。
In addition to the guide rail of the air compressor not meeting the requirements, there are also problems with the air compressor cylinder on the machine, such as the axis line of the air compressor cylinder is not parallel to the guide rail; The arrest section in the cylinder block hole is rusted and strained; Poor accuracy of air cylinder bore, piston rod and piston; Poor installation accuracy of air cylinder, poor coaxiality of piston, piston rod, cylinder block hole and cylinder head hole, etc.
由此可见,要想从根本上避免空气压缩机爬行,土工布就得让它的导轨和空压缸的设计、制作和安装都得严格按照标准进行,同时在后期的使用过程中还要做到机器的维护和保养。
It can be seen that in order to fundamentally avoid the crawling of the air compressor, the design, manufacture and installation of the guide rail and air compressor cylinder of the geotextile must be carried out in strict accordance with the standards, and the maintenance and repair of the machine must be done in the later use process.
