壓力開關(guān)的現(xiàn)場故障分析
壓力開關(guān)在施工現(xiàn)場出現(xiàn)的故障絕大多數(shù)是由于用戶的使用和安裝方法不當(dāng)引起的，主要有以下幾個方面：
1.查看被測介質(zhì)是否符合壓力開關(guān)的使用要求，是否有因介質(zhì)帶顆粒或雜質(zhì)引起開關(guān)內(nèi)部的波紋管堵塞的情況，如果有應(yīng)及時疏通。
2.壓力開關(guān)的壓力設(shè)定值是否設(shè)置在壓力范圍的20%-80%之間，不可超出范圍設(shè)定，否則開關(guān)非常容易出現(xiàn)故障。
3.查看壓力開關(guān)的接線是否正確，電源電壓是否有過高或過低的情況，開關(guān)與設(shè)備之間的連接端子是否接觸良好。
4.未嚴(yán)格按照技術(shù)要求進(jìn)行安裝，導(dǎo)致了開關(guān)出現(xiàn)了泄漏的情況。
