With the continuous development of science and technology, machinery and equipment are developing in the direction of automation, and truck-mounted drilling rig is one of them. In the drilling industry, the degree of automation and remote control technology of truck-mounted drilling rigs is getting faster and faster, which is also the general trend of future development. The advantage of the automatic production of the truck-mounted drilling rig is to improve the production efficiency of the truck-mounted drilling rig, effectively reduce the production cost, and virtually improve the production quality. Let's learn about the advantages and drilling methods of truck-mounted drilling rigs with Bian Xiao.
Advantages of 1. truck-mounted drilling rigs.
1. The mud pump of the truck-mounted drilling rig has strong self-priming ability, and the 10-level adjustable flow can meet the production requirements;
2. The drill pipe of the truck-mounted drilling rig has good performance and is self-important. When drilling, efficient production can be completed by relying on self-weight pressure;
3. The hydraulic pressure of the truck-mounted drilling rig is large, which can reduce the labor intensity of the operator and save the operator at the same time;
4. The vehicle-mounted drilling rig is equipped with four sets of hydraulic outriggers, which can adjust the extension length of different outriggers at will to adapt to different workplaces. Moreover, the positive and negative circulation work of the water well drilling rig can be realized on the operating platform, and the operation is convenient and flexible.
2. vehicle drilling method.
1. Reverse drilling method: In the production of this method, the truck-mounted drilling rig uses a ring drill bit with cemented carbide welded at the bottom to drill. When drilling, the truck-mounted drilling rig must apply a certain production pressure to ensure that the drill bit cuts into the rock and soil layer during drilling to achieve the most stable drilling intention;
2. Scour drilling method: in the production of this method, the vehicle-mounted drilling rig needs to use high-pressure water flow to impact the bottom soil layer of the hole, thus destroying the production structure of the soil layer, and the soil particles are suspended, and finally out of the hole with the water flow circulation;
3. Impact drilling method: when the truck-mounted drilling rig uses the gravity of the drilling tool and the impact force generated in the process of falling, the drill bit of the truck-mounted drilling rig impacts the rock and soil at the bottom of the hole and destroys it, so as to achieve the drilling method;
4. Oscillating drilling method: the vehicle-mounted drilling rig uses the oscillating force generated by mechanical power, and then transmits the power to the drill bit through the action of the drilling tool and the connecting rod, so that the oscillating force can make the drill bit break the earth and rock well, thereby improving the vehicle The drilling speed of the drilling rig.
