如何防止空气进入液压系统?

发表时间:2017-06-17 10:27  责任编辑:申博sunbet官网设备  点击: 次

  厂家介绍,通常情况下,液压系统中所使用的油液只具有很小的压缩性。而且很多时候其的影响都是忽略不计。不过,由于低压空气的可压缩性很大,大约可达到油液的一万倍,因此即使系统中仅仅含有及少量的空气,都有可能会带来很大的影响。如果有空气进入到液压系统之后,那么有一部分的空气会溶解在油液中。当系统压力降低的时候,这些空气又会跑出来,产生气泡,形成形成空穴现象,而在高压区这些气泡在压力油的作用下又瞬间被击碎,受到急剧压缩,就会引起系统中出现较大的噪声。

  Shandong hydraulic cylinder manufacturers are introduced, usually under the hydraulic system used in the oil has only a small compression. And most of the time, the impact is negligible. However, due to the compressibility of low-pressure air, about ten thousand times the amount of oil, so even if the system contains only a small amount of air, it may have a great impact. If air enters the hydraulic system, a portion of the air is dissolved in the oil. When the system pressure is reduced, and the air will run out of air bubbles, the formation of cavitation, and the high pressure area of the bubbles under the effect of the pressure oil and instantly crushed by the sharp compression, it will cause larger noise in the system.

  当然,这些空气一旦混入到液压油当中,还非常容易引起液压油的变质,因此我们必须要注意防止空气进入液压系统。申博sunbet官网油缸厂家建议,从空气进入系统的不同原因进行分析,那么我们在使用的时候,需要注意的问题有:1、经常检查油箱中的液面高度,保持其的高度适合;2、尽可能防止系统内各处的压力低于大气压力,同时应保证密封装置性能良好。

  Of course, once these air mixed into the hydraulic oil, but also very easy to cause deterioration of hydraulic oil, so we must pay attention to prevent air into the hydraulic system. Shandong hydraulic cylinder manufacturers recommend, carries on the analysis from the different causes of air into the system, so we need to pay attention when in use, the problems are: 1, always check the liquid level in the tank, maintaining its height; 2, as far as possible to prevent the pressure below the atmospheric pressure throughout the system, and ensure the sealing device performance is good.

  申博sunbet客户端厂家认为,最好还要在油缸的上部设置相应的排气阀,这样的话,就可以及时将进入到系统内部的空气排出去。

  Hydraulic cylinder manufacturers believe that it is best to set up the corresponding exhaust valve in the upper part of the cylinder, so that you can promptly enter the system inside the air out.
