往复式压缩机在运转中可以用一种简便而经济的技术来测量活塞杆的挠曲和位移。这种测量能指示出滑动元件的过份磨损和活塞杆因过份弯曲而引起破坏的可能性。要安全估计往复式压缩机的运行时间,必须知道两种情况:即滑动元件(活塞环、导向衬带、十字头滑履等)的情况,和在载荷下活塞杆的挠曲。任何滑动元件的过份磨损都会加速对其它滑动或固定元件的磨损和破坏。不正常的活塞杆的弯曲会引起活塞杆破坏,这不仅是一种机械破坏,而且会产生对安全的极大威 Reciprocating compressors operate in a simple and economical way to measure the deflection and displacement of piston rods. This measurement can indicate the excessive wear of the sliding element and the possibility of damage to the piston rod due to excessive bending. To safely estimate reciprocating compressor run-time, two conditions must be known: the condition of the sliding element (piston ring, guidebelt, crosshead shoe, etc.) and the deflection of the piston rod under load. Excessive wear of any sliding element accelerates wear and tear on other sliding or fixed elements. Abnormal bending of the piston rod can cause the piston rod to break, which is not only a mechanical damage, but also produces a great safety on the Granville
