每台压铸机上都装有几块甚至十几块普通压力表。压铸机频繁的启动、合模、压射、开模 ,与其相应的管道内部液压在瞬间真空与最大值之间急剧变化 ,造成压力表指针回零过猛 ,撞击限位钉 ,使表针弯曲变形、折断 ,有时将限位钉打掉也是常有的事。因此 ,在很短的时间内 ,压力表即失 Each die-casting machine is equipped with a few even a dozen ordinary pressure gauge. Die-casting machine frequent start-up, clamping, injection, mold, and its corresponding pipeline within the hydraulic pressure between the instantaneous vacuum and the rapid change between the maximum, causing the gauge pointer back to zero too much, impact limit nail, the needle bending deformation , Broken, and sometimes limit the nail knocked down is also common. Therefore, in a very short period of time, the pressure gauge is lost
