well drilling rigs for saletunability, low energy consumption (about 1/3 of the rock drill pneumatic); efficiency ; ease of automation and computer control of the work environment improved considerably. Hydraulic rock drill works: The machine is mainly composed of oil supply and oil distribution systems, energy storage systems, energy conversion system, damping hydraulic drill rigs for sale and support system, and operating tools system components. The impact cyclic process can be divided into four stages. The first stage: by the high-pressure oil source to the hydraulic oil into the lower end of the plunger, push the plunger up. Second stage: the plunger in the increase in the process, the valve sleeve pushed upward, until the designated position, then the high-pressure oil through the valve sleeve and the plunger between the calibration inlet to the oil supply to the cavity, while the nitrogen gas reservoir Connectors diaphragm compressed nitrogen up energy storage. Third stage: When the plunger on the end face by the fluid pressure exceeds the lower end of the liquid pressure, the force imbalance of the plunger accelerate the downward movement, water well drilling machine while the energy storage device to provide the amount of the oil required by the rapid movement. In the process of the downward movement of the plunger will throttle apertures open, so that the valve sleeve also decline. The plunger downward movement until the date borehole drilling rig suppliers collide with broken tools produce blow. Fourth stage: the valve sleeve in a downward movement of the process, cutting off the oil supply to the chamber, and communicating it with the low pressure return passage, so that the whole process has to return to the initial position. Again and again, so that can be automatically pummeled. The advantages and disadvantages of the of Chapter hydraulic rock drill The cycle of high-pressure hydraulic rock drill using oil as a driving force to overcome a series of problems and defects pneumatic rock drill. Than pneumatic rock drill, has the following advantages: (1) less power consumption, high energy utilization.
