Application scope and characteristics of drilling rig
All drilling rigs here are multifunctional, it can be used with air compressor, mud pump, even we can just use the dry hydraulic drilling method.
The drilling rigs are not only designed for water drilling. They can be used in all conditions based on pore-forming purpose.
They are widely used in industrial and agriculture water project, testing well and other exploration borehole. In particular, drilling hole for geothermal heating, it can also meet the engineering basis for reinforcement, loose gravel drilling rock formation connected with a variety of engineering.
Our drilling rigs are more efficiency and with low failure rate, more economic and durable, and with a high comprehensive cost performance.
Host structure and working principle
1. Chassis rubber wheel chassis. Drag to walk.
2. The frame of frame welding structure is welded on the chassis. When the carriage is erected, it can be connected with the frame with bolts
As a whole, improve the rigidity of the carriage.
3. The carriage with welded structure adopts hot-rolled carbon channel steel and square steel pipe as the guide rail of the swivel head,
The oil cylinder is controlled to rise and fall smoothly through the one-way throttle valve. The verticality is controlled by the level and angle gauge on the console.
4. The slewing mechanism is composed of hydraulic motor and slewing reducer. Two high-performance low-speed high torque hydraulic horses
To drive the rotary reducer, you can obtain different torque and speed.
How to maintain water well drilling rig?
The manufacturer of water well drilling rigs said that when we use water well drilling rigs, we should not forget to maintain them. What should we pay attention to? Pay attention to check the lubricating oil condition of the wind motor at any time. Pay attention to check whether the water and gas pipelines and the bolts and nuts of all accessories of the drilling rig are firm at any time. When the working face is immersed in water, use a large-diameter drill head to insert the drill pipe when opening the hole, so that the drill pipe is 1-2 meters above the water surface, so as to prevent mud and rock debris from falling into the hole. It is not allowed to reverse during the drilling operation of the water well drilling rig, so as to prevent the drill pipe from falling into the hole, When the water well drilling rig stops working in a short time, a small amount of air pressure should be given to prevent sediment from immersing into the interior of the drilling rig impactor. If the drilling rig stops working for a long time, the sound of the impactor and the operation of the reducer should be checked. If abnormal sounds and phenomena are found, the machine should be shut down immediately and checked in time.
