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.

對于空氣壓縮機(jī)來說，爬行將會對其造成很大的危害，因此要排除。但是同樣是爬行，其故障現(xiàn)象是有區(qū)別的：有規(guī)律的爬行；有無規(guī)律的爬行；有的爬行無規(guī)律且振幅大；有的爬行在低的速度下產(chǎn)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.

如何來理解空氣壓縮機(jī)的爬行現(xiàn)象

How to understand the crawling phenomenon of air compressor

空氣壓縮機(jī)產(chǎn)生這些不同現(xiàn)象的爬行，其原因各有不同的側(cè)重面：有些以機(jī)械方面的原因為主、有些以空壓方面的原因為主、有些以油中進(jìn)入空氣的原因為主、有些以潤滑不好的原因為主。維修人員要不斷總結(jié)歸納，迅速查明產(chǎn)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.

為了有用解決空氣壓縮機(jī)的爬行問題，需要解決運(yùn)動部件的摩擦狀態(tài)和機(jī)器運(yùn)動的平衡性。而造成這方面出現(xiàn)問題的原因有很多，比如導(dǎo)軌精度差，導(dǎo)軌面嚴(yán)重扭曲；導(dǎo)軌面上有銹斑；導(dǎo)軌壓板鑲條調(diào)得過緊，導(dǎo)軌副材料動、靜摩擦因數(shù)差異大；導(dǎo)軌刮研不好、點(diǎn)數(shù)不夠，點(diǎn)子不均勻；導(dǎo)軌上開設(shè)的油槽不好，深度太淺，運(yùn)行時已磨掉，所開油槽不均勻，油槽長度太短等等。

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.

除了空氣壓縮機(jī)的導(dǎo)軌不符合要求之外，還有機(jī)器上的空壓缸的問題，比如空壓缸軸心線與導(dǎo)軌不平行；缸體孔內(nèi)拘捕段銹蝕和拉傷；空壓缸體孔、活塞桿及活塞精度差；空壓缸及安裝精度差，活塞、活塞桿、缸體孔及油缸蓋孔的同軸度差等。

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.

由此可見，要想從根本上避免空氣壓縮機(jī)爬行，土工布就得讓它的導(dǎo)軌和空壓缸的設(shè)計、制作和安裝都得嚴(yán)格按照標(biāo)準(zhǔn)進(jìn)行，同時在后期的使用過程中還要做到機(jī)器的維護(hù)和保養(yǎng)。

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.
