三、工作原理
?1.鉆機(jī)的油壓系統(tǒng)均由油泵將壓力油泵通過管道經(jīng)多路閥控制，根據(jù)需要在送達(dá)各執(zhí)行機(jī)構(gòu)，使它完成各項動作。
?2.減速機(jī)將動力經(jīng)變速傳至輸出軸，帶動鉆桿和鉆頭進(jìn)行回旋運(yùn)動，完成正轉(zhuǎn)（順時針方向）進(jìn)行切削工作，（反轉(zhuǎn)做卸鉆桿時用）正常鉆孔中禁止反轉(zhuǎn)。（反轉(zhuǎn)會引起掉鉆桿，鉆頭事故）
3.正、反循環(huán)的操作：
?3.1在施工中如遇到地層或洗井原因需要更換鉆孔工法時，其操作步驟是，以正循環(huán)為例，操作液壓手柄，關(guān)閉大泥漿泵上的壓閥，啟動3PNL小泥漿泵，水經(jīng)管道經(jīng)大泵、鉆桿、進(jìn)入鉆尖底部，使孔中的切削泥渣被水流托起順井管流到沉淀池。經(jīng)沉淀水又進(jìn)入3PNL泥漿泵，形成循環(huán)。
反循環(huán)工法，主機(jī)旋轉(zhuǎn)，關(guān)閉大泵閥門，啟動3PNL漿泵，給大漿泵灌泵，使空氣排空，啟動大漿泵同時開啟閥門，關(guān)閉3PNL漿泵，大泵出水正常**可正常工作。（如果鉆桿中的空氣未排空，或有地方漏氣，將影響大泵出水）。正反循環(huán)可隨時互換。同時反循環(huán)可做正循環(huán)鉆孔完成清孔（清除沉淀）工作。
3.2鉆機(jī)的下籠及灌灰
樁孔完成后，提出鉆桿，鉆頭，鉆機(jī)同時向后移動合適的位置，視機(jī)架上副額頭吊鉤對準(zhǔn)樁孔**為準(zhǔn)，同時卷揚(yáng)**可下籠和灌注商品灰。
Three, working principle
1 the hydraulic system of the drilling machine is controlled by the multi way va*e of the pressure pump through the pipeline, and it is required to be served on the executive body, so that itcancomplete the action.
