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(xiàng)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(shí)針方向）進(jìn)行切削工作，（反轉(zhuǎn)做卸鉆桿時(shí)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(shí)，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(shí)開啟閥門，關(guān)閉3PNL漿泵，大泵出水正常就可正常工作。（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(shí)互換。同時(shí)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(shí)向后移動合適的位置，視機(jī)架上副額頭吊鉤對準(zhǔn)樁孔中心為準(zhǔn)，同時(shí)卷揚(yáng)就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 valve of the pressure pump through the pipeline, and it is required to be served on the executive body, so that it can complete the action.
2.The reducer will power transmission is transmitted to the output shaft, drive drill and cyclotron motion, complete forward (clockwise) carry on the work of cutting and (reversal unloading the drill pipe) in normal drilling ban reversal (reversal will cause the drop of drill pipe, drill bit accident)
3.positive and reverse circulation operation:
3.1 in construction such as encountered strata or clear hole and need replacing the positive and reverse circulation, take the positive cycle, for example, hydraulic operation handle large mud pump pressure valve closed, start small 3pnl mud pump, mud through a pipeline, after pump, drill pipe, into the bottom of the bit, mud by water hold up along the pipeline flow into the mud pool. After precipitation of water into the 3PNL mud pump, the formation of circulation.
四、鉆機(jī)的安全操作規(guī)程
