機械壓力開關的故障
今天小編為大家歸納了機械壓力開關容易出現的兩個小故障，一是設定的壓力值有變動現象，二是機械壓力開關的失靈故障。
1.當壓力開關設定的壓力值出現了變動的情況，很可能是由以下因素造成：
（1）機械壓力開關內部的彈性元件出現了變形的情況；
（2）機械壓力開關的敏感元件波紋管出現了泄露；
（3）機械壓力開關的微動開關出現了位移；
針對上述三種現象，維修人員可以進行彈性元件的更換、密封性能的檢測、調整微動開關的位置等措施進行解決。
2.機械壓力開關的測量不準確而且偶爾還出現了失靈的情況，這種情況很可能是因壓力開關使用時間過久而導致內部零件出現機械磨損，維修人員可以通過檢測、維修或者更換零部件進行解決。
