Hydraulic fracturing machine for high volume fracturing, the drilling machine shall be equipped with a punch to the first division aniseed. When drilling machine drilling, each splitting machines to be equipped with two sets, in order to improve production efficiency splitting machine. When pre-drilled holes to release the single-head hydraulic fracturing, start the motor, when the hydraulic cylinder piston rod push the wedge down movement, observe, when you see the stone that cracks along the orifice (also available from pressure gauge on the observation, when the pressure rises to a certain value commanded suddenly Bian drop) reversing valve, then the reverse movement of the wedge, splitting device when it is reset after an angle of rotation, repeat the splitting process, so can be multi-directional split in a hole, the stone split into multiple pieces, reduce the workload of the borehole. China's stone production accounts in the world, in mining requires a lot of large rocks on the secondary disintegration. Stone splitting, always rely on manual knock mason chisel, not only inefficient, but also labor-intensive. Hydraulic fracturing machine is used for the second solution of rock `body, low-cost, high re-creation of value, a good solution to the problem of stone secondary Solutions' body. Since the compressive strength is far greater than most rock tensile and shear strength, the ratio is about 10: 1. Therefore, splitting large rocks from the inside, is one of the most effortless way. Hydraulic fracturing machine simple structure, easy to operate, safe and reliable, splitting speed, high efficiency, low cost, significant economic and social benefits. The machine can replace the use of proven baopo, a chunk of rock twice Solution? One ideal method body.
