液压缸作高速往复运动时,具有很大的动量,这样在行程的终端,如果活塞与端盖产生机械碰撞,将会产生很大的冲击和噪声。这种机械冲击的产生,不仅会引起液压缸各部分的损坏,而且严重影响与之连接管路及阀类。因此,液压缸设置缓冲装置极为重要。目前较多采用改变油路的通流面积,来实现缓冲目的。下面介绍一种加工工艺中容易保证的缓冲装置。 Hydraulic cylinder reciprocating at high speed, with great momentum, so that in the end of the trip, if the piston and the end cover of a mechanical collision, will have a great impact and noise. This mechanical shock generated, not only will cause damage to various parts of the hydraulic cylinder, but also seriously affect the connection with the pipeline and valves. Therefore, the hydraulic cylinder buffer device is extremely important. At present, more use of the change of oil flow area, to achieve the purpose of buffer. The following describes a processing technology easy to ensure that the buffer device.
