ST 260 Pneumatic Drilling Rig Features
1. The engine uses a high-power engine;
2. Walking device: the walking motor is equipped with a gear box, which is durable and has a long life;
3. Hydraulic oil pump; parallel gearbox design with separate oil pump units, sufficient power supply and reasonable distribution, unique hydraulic system design, simple maintenance and low cost;
4. Power head device; gearbox is cast in one piece, dual motors provide power, large torque, durable, and low maintenance cost;
5. Drilling rig chassis; professional excavator chassis, durable, large load-bearing, wide chain plate, little damage to hard roads;
6. Lifting force; patented design composite boom, the boom is small in size, long stroke, double cylinder lifting, large lifting tonnage;
7. The lifting boom of each drilling rig is equipped with a stopper to protect the safety of the oil cylinder and ensure the safety of work;
8. Each hydraulic oil pipe is covered with a protective jacket to make the service life of the oil pipe longer.
1. After the drilling structure of the drill bit of the water well drilling rig is drilled, the central drilling tool needs to be replaced in time. First, the hole bottom needs to be cleaned, and then the residue at the hole bottom needs to be blown away. After the drill bit stops rotating, the drilling tool in the water well drilling rig can be lifted up slowly. When the lifting force is just enough to lift the drilling tool, it is the most appropriate.
2. During the drilling process, the drill bit of the water well drilling rig shall be summarized. It is also necessary to carefully observe the follow-up situation of the casing, timely understand the specific situation in the hole, and keep the hole clean when necessary. Moreover, the drill bit in the water well drilling rig shall not be pulled out by force during the drilling process.
3. Sometimes there will be more residual rock slag at the bottom of the hole of the water well drilling rig, and the rotating part of the eccentric bit will be stuck by the rock slag, which will affect its retraction and production. At this time, it is necessary to transport air pressure, clean the hole again, make the DTH hammer work in a short time, and then lift the central drilling tool again.
