800m Depth SNR800C Crawler Type Water Well Drilling Rig Machine For Monitoring Wells

SNR800C drilling rig is a kind of high efficient full hydraulic multifunctional water well drill rig for drilling up to 800m 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. 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.

SNR800C 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.Rotating and feeding system are controlled by hydraulic pilot control which can achieve step-less speed regulation.

Main performance parameters of SNR800C water well drilling rig machine :

Features of SNR800C water well drilling rig machine :

1. SNR800C water well drilling rig can be used for multi-function 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.
2. Full hydraulic control is convenient and flexible. 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.
3. High efficiency and low cost. 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.
4. SNR800C water well drilling rig can be equipped with high leg crawler chassis. Four hydraulic support jacks can level rapidly undercarriage to ensure the drilling accuracy. The support jack extension as optional can be easy to make the rig load and unload on truck as Self-loading by itself, which save more transportation cost
5. Optional rig chassis. The SNR800C water well drilling rig can be mounted on crawler chassis, truck chassis or trailer chassis.
6. The positive and negative axial pressure can be adjusted. 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.
