LDZ-300礦用指針式錨桿拉力計(jì)工作原理:
液壓泵站在開始工作時,液壓油被柱塞吸入高、低壓吸油單向閥,通過高、低壓排油單向閥壓入工作空心千斤頂,當(dāng)壓力升到1.5MPa時,則低壓溢流閥打開,低壓油溢回油箱;升壓工作:在上述基礎(chǔ)上,高壓柱塞繼續(xù)工作,壓力逐漸升高,推動空氣千斤頂工作,從而實(shí)現(xiàn)對錨桿的拉拔。當(dāng)壓力直過63MPa時,則高壓閥打開,高壓油從高壓閥溢回油箱,壓力始終保持在63MPa。
錨桿拉力計(jì)根據(jù)拉力又分為:10T錨桿拉力計(jì),20T錨桿拉力計(jì),30T錨桿拉力計(jì)等三種型號。您可以根據(jù)自己的需要選擇訂購
