First, let's consider funding. The price of large rotary drilling rigs is in the millions. If we can have sufficient funds, we can choose this type of drilling rig. The price of small rotary drilling rigs is between 200000 and 700000, the price of square rod rotary drilling machines is generally between 200000 and 300000, and the price of machine lock rod rotary drilling machines is between 300000 and 700000. You can choose to buy them according to your own situation.

Rotary drilling rig shall be selected according to construction conditions. Large rotary drilling rig must be used for pile foundations with deep drilling depth and large hole diameter. The hole-forming depth of the square rod rotary excavator is 5-30m and the hole-forming diameter is 500-1500mm, which is suitable for soil layer construction. The hole-forming depth of the machine lock rod rotary excavator is 5-38m, and the maximum diameter is 1600mm, which can be used for strongly weathered and moderately weathered geological operations.

Decryption of Power Head Structure of Rotary Drilling Rig

The power head is the most important working mechanism of the drilling rig. Taking effective maintenance and maintenance measures can better guarantee the performance of the drilling rig and create greater economic benefits for customers. 1. the maintenance and maintenance of the power head drive device. The first oil change shall be carried out after the first 100 hours of work in the early stage. After that, the lubricating oil shall be replaced every 1000 hours or 12 months (according to the earliest one). Check the tightness of all screws and bolts at least once a month. 1. Check and add lubricating oil of driving device: A. Observe the oil level through the oil level sight hole 2 above the power head reducer to ensure that the oil level is located on the upper red mark line and the lower red

How to solve the oil leakage of power head of rotary drilling rig?

At present, there is a common phenomenon of oil leakage in the power head of rotary drilling rig. As the power drive device of rotary drilling rig, the sealing oil leakage problem seriously affects the construction environment and construction cost. If the oil leakage is serious, the sealing must be stopped and replaced, which will cause great economic losses to the construction unit and users. The sealing principle of the power box of the rotary drilling rig: the lubrication of key parts such as gear transmission and bearings in the power box of the power head of the rotary drilling rig is realized by gear oil in the box, and the sealing of gear oil is realized by the oil film in the box between the rotary seal and the rotating shaft.
