The water well drilling rigs for sale timely adjustment propulsion size, to make hydraulic rock drill rotary resistance timely down torque of the rotating mechanism slightly lower. Performance of hydraulic rock drill rotary speed is another important parameter, which affects the impact crusher each time breaking rocks the size of, but also affect the size of the rotary twist cut the amount of rock breaking, so that the chisel-speed changes. The turning mechanism of the hydraulic rock drill are almost independent of the impact mechanism, its performance parameters punctured speed impact, mainly because it will enable the variation of the propulsion force. We summarize the truck mounted drill rigs experimental laws: (1) Impact performance parameters, the rotary speed is constant, the thrust force is increased, rotation torque increase, within a certain range, the punctured speed increased, but the optimum propulsive force up to a maximum point later, then increase in the propulsive force slowdowns make the punctured. Hydraulic drilling machine having a rotary torque value, i.e., can reach the level of the maximum torque value on the rock drilling process to blast hole drill rigs for sale ensure optimum propulsion role. (2) hydraulic rock drill propulsive force constant impact performance parameters and drilling, hydraulic crawler drill for sale hydraulic rock drill Best Drilling speed best speed and torque with engine speed to improve and improve. (3) transfer the braze speed and drilling hydraulic rock drill propulsion unchanged by the impact energy has little effect on the actual output torque. Raise awareness of the importance of crawler drill rig rotary hydraulic rock drill performance, should be in product development, manufacturing and use of hydraulic rock drill the rotary performance as an important indicator of.

The drilling rigs can fully meet the well-drilling- process requirements by adoption of flexible driving designs- mechanical drives (high-speed diesels, hydraulic transmission box, angle gear box or middle-speed diesel hydraulic transmission, chain combination box), compound transmission and electrical drives (VFD or SCR) etc. * The whole unit is very compact and a quick whole transportation and installation of the whole drilling rig can be realized due to a utilization of a skid-mounted structure. In addition, the drilling rig requires a small working site due to its high integration and compact configuration. * Masts and substructures have various structures, such as: perpendicular-hoist sectional mast, whole-hoist K-type mast, telescopic substructure, spirally hoisted substructure and folding - frame substructure. * A standard and module design and various ways of combination have been adopted in order to boost up the universal and exchangeable performances of the drilling rigs and to meet the user different requirements. * Disc brake or band brake can be applied as main brake and air brake or FDWS brake can be used as auxiliary brake and the energy-consumption braking can be available for electrical-drive-rig auxiliary brake. The drawworks can be equipped with bit-feed motor and control system. * The Internet and communication techniques have been used on the drilling rigs, which can realize an integral display for power, air control, hydraulic control, and monitoring and the intellectual and safe control of the driller. * The perfect configurations of the solid control system, well control system, high-pressure pipe manifold system, the generator house, the engine pump house, doghouse and other auxiliary facilities can meet the user different requirements. Safety and inspection measures are strengthened under the guidance of the design concept of ° Humanism Above All¡± to meet the requirements of HSE.
