Product Description

Product Description

The lifting of the drilling frame, drilling rod unloading, rotation and feeding, support legs, hoisting, walking and other actions of the Zhengyuan series drilling rig are all implemented by hydraulic systems, greatly reducing labor intensity, improving construction efficiency and engineering quality. The telescopic tower type drilling rig reduces the length of the drilling frame by twice and can directly lower 6/7 meters of drill rods or casing, further shortening the drilling assistance time. The updated rotary control panel can be used for different working conditions.

 
Advantages and On site Construction

1. Low cost. Drilling on rocks is mainly carried out using the down the hole hammer drilling technique, which has high efficiency and lower cost per meter. And the whole machine is sturdy and durable, with a low failure rate and high reliability. Significantly reduce your maintenance costs in the later stage.
2. High leg track type. High support legs are convenient for loading and transportation, and can be directly loaded without the need for a crane. Crawler walking is more suitable for moving on muddy sites.
3. The unique positive and negative axial pressure adjustment of the fully hydraulic drilling rig. The optimal impact efficiency of various impactors has its matching optimal axial pressure and rotational speed. During the drilling process, as the number of drill rods increases, the axial pressure on the impactor also increases. Therefore, during construction, the positive and negative axial pressure valves are adjusted to ensure that the impactor can obtain a more matching axial pressure. At this time, the impact efficiency is the highest.

 

4. Oil mist generator and oil mist pump with patented technology. Lubricate the high-speed impactor at all times during the drilling process to maximize its service life.
5. Drilling rig chassis. It can be a tracked self-propelled chassis, a vehicle mounted self-propelled chassis, or a trailer mounted chassis.
Within the same industry, second tier smartphones have higher value. Due to the use of imported brands for the main components of the drilling rig, as well as the use of high-quality high-strength low-carbon alloy steel for the main frame, the overall strength is increased and it is super wear-resistant. In addition, there is a heavier hydraulic system, which is very valuable.

Advantages of fast drilling
High speed drilling performance
The 400m water well drilling rig adopts a high-speed power head design, significantly improving drilling efficiency. By increasing the rotation speed and accelerating the contact frequency between the drilling tool and the formation, rapid penetration can be achieved, especially in soft formations.
Save drilling time
Compared with traditional drilling rigs, the 400m water well drilling rig can increase drilling speed by about 30% under the same geological conditions, significantly shorten the construction period, and reduce construction costs.
Comparison of drilling speed
The efficient drilling capability and optimized operation process significantly shorten the single drilling cycle, effectively saving overall project time and accelerating project progress.
Efficient rock breaking ability
The drilling rig is equipped with reinforced drilling tools to enhance the rock breaking effect. By utilizing the high hardness characteristics of alloy drill bits, rocks can be effectively cut, reducing the energy required for a single drilling operation and improving overall operational efficiency.

Efficient drilling technology system

1. Principle of Positive and Negative Circulation Technology

Positive circulation refers to the process where mud is pumped from the mud pump into the drill pipe, causing drilling debris to rise along the borehole wall and overflow into the mud pit; Reverse circulation refers to the flow of mud into the hole through the orifice, while the sand and gravel pump sucks up the slag at the bottom of the drill rod, causing the drilling slag to rise along the drill rod with the mud and be discharged from the faucet into the mud pit.

1. Drilling speed in hard rock formations

In hard rock formations, the drilling speed of water well drilling machines using forward and reverse circulation technology is generally 3-5 meters per day. For example, in actual drilling of granite formations, the forward circulation technology has a drilling speed of about 3 meters per day, while the reverse circulation technology is slightly faster, reaching 4-5 meters per day.

 

Principles of modular design
Modular design is the process of decomposing a water well drilling machine into multiple independent modules, each with specific functions that can be combined and adjusted according to different environments and requirements.
-45 ºC extreme cold environment application data
In an extremely cold environment of -45 ºC, the modular design of the water well drilling machine ensures the normal operation of the equipment through special insulation materials and heating systems. For example, in a polar scientific research project, the drilling rig operated continuously for 10 days in an environment of -45 ºC, and the equipment failure rate was less than 5%.
Application data for high temperature environment at 50 ºC
In a high temperature environment of 50 ºC, modular design of heat dissipation modules can effectively reduce equipment temperature. In a drilling project in a desert area, the drilling machine worked continuously for 20 days at a high temperature of 50 ºC, with stable equipment performance and no significant impact on drilling efficiency.
Advantages of adaptability to extreme environments
Modular design enables water well drilling machines to adapt to different extreme environments, expand the range of equipment use, improve equipment reliability and stability, and provide strong support for drilling operations in complex environments.
