SNR400C multifunctional crawler mounted water well drilling rig
SNR-400C is a kind of light and high efficient multi-functional water well drilling rig with steel track,it is widely used in engineering construction for drilling wells,monitoring wells and ground-source heat pump air-conditioner and also applied in hole blasting,bolting and anchor cable,etc.Top drive rotary power head and a hydraulic rotary disk rotating mechanism,hydraulic motors,hydraulic winch chain propulsion for deep hole drilling in institutions and mast.The driller adopts the rotary drilling technology of reverse circulation drilling technology,mud,compressed air DTH hammer drilling technology,can finish cover layer,sand gravel,sand,rock layer stratum,large diameter deep hole construction.The drill,drill pipe rack lift unloading,leveling supporting legs,lifting,walking and other auxiliary movement by the hydraulic system,not only can improve the working efficiency,and reduces the labor intensity of operators.
1. Rig type of optional equipped with high leg for self loading Crawler and truck type, optional diesel engine or motor power.
2. The combined pump transfer case, hydraulic rotary power head, the motor chain propeller, wa ter pump, mud pump parts such as hydraulic configuration, reasonable power matching, speed, pressure regulating block stepless adjustment, achieve a variety of drilling parameters, meet a variety of drilling technology, adapt to the whole formation drilling requirements.
3. Multiple drilling technology: the soil and sand pebble bed reverse circulation drilling. Moisture rock combination of large diameter DTH hammer drilling composition, All air leakage formation drilling a hole deep casing to follow up. Deep hole water, gas, three complex strata combination DTH hammer drilling mud.
4. Patent method: rock hole diameter of 600 mm, moisture combination of DTH hammer drilling, save 50% use air compressor, improve the efficiency of 20%. 300mm diameter drill 800 m deep water, gas, DTH hammer drilling mud three medium combinations, alternative roller rock drilling, improve the speed by 200%.
5. High pressure mud pump, positive and negative circulation pumps, drilling frame lifting, drilling platform opening and closing, the drill pipe discharge, leveling, winding, drill leg walk all with auxiliary motion of the controlled by hydraulic, such as improving construction efficiency.Reduce the intensity of the operator work.
6. Hydraulic system equipped with separate air-cooled hydraulic oil cooler, and can optional install water cooler to ensure hydraulic system keep continuous and efficient operation under the high-temperature weather conditions of different regions.
