Prevention method of drilling tool breaking of water well drilling rig
1. All pipes, joints and couplings shall be stored and used according to the new and old degree. Check the bending and wear of drilling tools by lifting and lowering drilling tools, correcting hole depth and relocation time.
2. It is forbidden to use a sledge hammer to knock the drill pipe and its joint when screwing and unloading the drilling tool.
3. When the rotary resistance is too large during reaming or drilling, it is not allowed to start the machine forcibly.
4. Master reasonable WOB, and do not blindly pressurize drilling.
二十六，转盘的重要性
我们在选择打井机转盘的时候，其转盘一定要选择大扭矩的以及一定转速的。这样才能够保障打井机能够正常的运行和保障工作效率。 然而，大家应该明白的是对于打井机转盘的选择要选择具有抗震性能的转盘，以及要能够耐受冲击和防止腐蚀的能力。这样的转盘才能够在打井机运行的时候提高工作效率，增加使用寿命。由于打井机在运行的时候需要循环的转动，因此对于转盘的选择一定要注意选择能够正反旋转的。如此一来就能够保障打井机的正常运行，另外对于在选择转盘的时候还要注意其密封性如何，选择密封性好的以及润滑效果好的转盘。以免在运行中泥浆或者其他的脏东西进入到转盘中。如果不小心进入脏东西，那么就会影响到转盘的正常转动，使打井机停止运行
When we select the rotary table of the drilling machine, we must select the rotary table with high torque and a certain speed. Only in this way can we ensure the normal operation and work efficiency of the drilling machine. However, it should be understood that the rotary table of drilling rig should be selected with anti-seismic performance and the ability to withstand impact and prevent corrosion. Such a rotary table can improve the working efficiency and increase the service life when the drilling rig is running. Since the drilling machine needs to rotate circularly during operation, the rotary table must be selected with positive and negative rotation. In this way, the normal operation of the drilling machine can be guaranteed. In addition, when selecting the rotary table, attention should be paid to its sealing performance. Select the rotary table with good sealing performance and good lubrication effect. To prevent mud or other dirt from entering the rotary table during operation. If you accidentally enter the dirt, it will affect the normal rotation of the rotary table and stop the drilling machine.
二十七，水井钻机在工矿铁路施工应用中的特点
1、水井钻机分为立柱架和座架两种钻架形式，可以根据煤的巷道高低和使用选择不同的钻架。
2、水井钻机在打孔同时能把网孔导管顶入孔内，这对于在打孔不成形的及松软煤层的高瓦斯矿井的瓦斯抽放解决了关键性的难题。所以该钻机又叫做导管钻机或顶管钻机。
3、水井钻机选用了高压密封钻杆和底孔马达，就能将钻进能力大大提高(避免了钻机扭动钻杆自身重量的强大扭矩力)，所以该钻机又称作底孔马达钻机。
4、水井钻机在配备一台高压水发生器和选用高压密封钻杆就能对透气性低的煤层进行割缝，从而提高瓦斯抽放效率和大大缩短抽放时间。该钻机采用液压传动机构，具有钻进能力大、速度快、操作简单、工作稳定可靠、移动安装方便等特点。
Characteristics of 1 well drilling rig in industrial and mining railway construction
1. The water well drilling rig is divided into two types of drill frames: column frame and pedestal frame. Different drill frames can be selected according to the height and use of the coal roadway.
2. The water well drilling machine can push the mesh pipe into the hole while drilling, which solves the key problem of gas drainage in high gassy mines with unformed holes and soft coal seams. So this drill is also called pipe jacking drill or pipe jacking drill.
3. The high-pressure sealed drill pipe and bottom hole motor are selected for the water well drilling rig, which can greatly improve the drilling capacity (avoiding the strong torque force of the drill pipe when the drill rig torques its own weight). Therefore, the drilling rig is also called bottom hole motor drilling rig.
4.When equipped with a high-pressure water generator and a high-pressure sealed drill pipe, the water well drilling rig can slit the coal seams with low permeability, so as to improve the gas drainage efficiency and greatly shorten the drainage time. The drill adopts hydraulic transmission mechanism, which has the characteristics of large drilling capacity, fast speed, simple operation, stable and reliable operation, convenient movement and installation, etc.
