SNR500 drilling rig is a kind of medium and high efficient full hydraulic multifunctional water well drill rig for drilling up to 500m and is used for water well, monitoring wells, engineering of ground-source heat pump air-conditioner, blasting hole, bolting and anchor cable, micro pile etc. Compactness and solidity are the main characteristics of the rig which is designed to work with several drilling method: reverse circulation by mud and by air, down the hole hammer drilling, conventional circulation. It can meet the drilling demand in different geological conditions and other vertical holes.
The drilling machine is driven by diesel engine, and rotary head is equipped with international brand low-speed and large-torque motor and gear reducer, feeding system is adopted with advanced motor -chain mechanism and adjusted by double speed. Rotating and feeding system are controlled by hydraulic pilot control which can achieve step-less speed regulation. Breaking out and in drill rod, leveling the whole machine, winch and other auxiliary actions are controlled by hydraulic system. The structure of rig is designed to reasonable, which is easy to operate and maintenance.
The speed, torque, thrust axial pressure, reverse axial pressure, thrust speed and lifting speed of the drilling rig can be adjusted at any time to meet the requirements of different drilling conditions and different construction technologies.
It is convenient to take over and unload the drill pipe, shorten the auxiliary time, and is also conducive to follow-up drilling.
All kinds of drilling techniques can be used on this kind of drilling machine, such as down the hole drilling, through air reverse circulation drilling, air lift reverse circulation drilling, cutting drilling, cone drilling, pipe following drilling, etc. The drilling machine can install mud pump, foam pump and generator according to the needs of users. The rig is also equipped with a variety of hoists to meet the different needs of customers.
Due to full hydraulic drive and top drive rotary propulsion, it is suitable for all kinds of drilling technology and drilling tools, with convenient and flexible control, fast drilling speed and short auxiliary time, so it has high operation efficiency. The down the hole hammer drilling technology is the main drilling technology of the drilling rig in the rock. The down the hole hammer drilling operation efficiency is high, and the single meter drilling cost is lower.
The high outrigger is convenient for loading and transportation, and can be loaded directly without crane. Crawler walking is more suitable for muddy field movement.
Efficient and durable oil mist device and oil mist pump. In the process of drilling, the high-speed running impactor is lubricated all the time to extend its service life to a greater extent.
The best impact efficiency of all kinds of impactors has its best matching axial pressure and speed. In the process of drilling, with the increasing number of drill pipes, the axial pressure on the impactor is also increasing. Therefore, in the construction, the positive and negative axial pressure valves can be adjusted to ensure that the impactor can obtain more matching axial pressure. At this time, the impact efficiency is higher.
The rig can be mounted on crawler chassis, truck chassis or trailer chassis.
Frequently Asked Questions
Q: What is the maximum drilling depth of the SNR500 drilling rig?
The SNR500 drilling rig is designed to reach a maximum drilling depth of up to 500 meters, making it ideal for deep water wells and monitoring wells.
Q: Which drilling methods are supported by this rig?
This multi-functional rig supports multiple drilling technologies, including down-the-hole (DTH) hammer drilling, conventional circulation, and reverse circulation by both mud and air.
Q: How does the top drive rotary propulsion system benefit operations?
The top drive rotary propulsion system makes connecting and unloading drill pipes highly convenient, significantly reducing auxiliary non-drilling time and facilitating follow-up drilling.
Q: Can the SNR500 operate in muddy or difficult terrain?
Yes. The rig can be equipped with a high leg crawler chassis. The crawler system is highly suited for movement in muddy fields, and the high outriggers allow for direct loading and transport without needing a crane.
Q: How is the impact efficiency optimized in changing geological conditions?
The rig features adjustable positive and negative axial pressure valves. As the number of drill pipes increases, operators can adjust these valves to keep the axial pressure and speed perfectly matched, ensuring maximum impact efficiency.
Q: What optional accessories can be integrated with this machine?
Based on operational requirements, users can install optional accessories such as a mud pump, foam pump, centrifugal pump, generator, and various hoists to meet different custom drilling demands.
