ST400 Water Well Drilling Rig Features:
1.The series of drill rig adopts a excavator crawler chassis and has strong off-road performance.
2. independent module design allows the drill to be mounted on the truck to increase its mobility. Two speeds of rotating and advancing speed can meet the different needs of soil and rock drilling. Combined positioner, the positioning disc can be adjusted and replaced according to different types of drill pipe and impactor, so as to ensure the accuracy and reliability of the positioning and centering.
3.The hoisting mechanism is convenient for hoisting of drill pipe and impactor, so as to reduce the labor intensity.
4.This machine can be applied to various strata, used in water well engineering, geothermal well, anchor pile hole and so on, and can be used with follow-pipe drilling. It has the advantages of whole machine hydraulic control, automatic loading and unloading drill pipe, crawler type chassis, large horsepower diesel engine, four hydraulic support leg balance, stronger terrain application ability and so on.
Structure and working principle
1. Chassis rubber wheel chassis. Drag to walk.
2. The frame of frame welding structure is welded on the chassis.
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.
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 can we do a good job in the maintenance of well drilling rig? Today, I'll talk about the five steps of well drilling rig
1. Pay attention to check whether the bolts and nuts of water and gas pipelines and various accessories of the drilling rig are firm at any time
2. . Always check the lubricating oil condition of the wind motor
3. . When the working face is immersed in water, a large-diameter drill head shall be used to insert the drill pipe when opening the hole, so that the drill pipe is 1-2 meters above the water surface to prevent mud and rock slag from falling into the hole
4. . The drilling rig is not allowed to reverse during drilling operation, so as to prevent the drill pipe from falling into the hole
5.. When the drilling rig stops working for a short time, a small amount of air pressure shall be given to prevent sediment from invading the interior of the percussion device of the drilling rig. If the drilling rig stops working for a long time, the percussion device shall be lifted 1-2m away from the hole bottom for fixation
