Hydraulic support jacks offer, Anhui hydraulic jack stand, good quality Big Star Coal Mine Machinery

 Big Star hydraulic mining machinery engineering from five parts: the cylinder and cylinder head, piston and piston rod seals, buffer device, exhaust. Hydraulic system is the most important executive power of the original, the hydraulic energy into mechanical energy. When one hole into the oil, the piston is pushed out of the oil to make another hole to achieve the principles of the rod back and forth. Big Star Coal Mine Machinery Co., compact hydraulic engineering structures, smooth, has a self-locking effect, it is widely used. Specialized in manufacturing various models hydraulic engineering, high quality hydraulic jack stand, trustworthy! Welcome to inquire Order! Engineering or giant mine supply cylinder is hydraulic energy into mechanical energy, and do a linear reciprocating motion (or swing movement) of the hydraulic actuator. Simple structure, reliable work. Use it to achieve a hydraulic jack the price bracket can be removed from deceleration devices small hydraulic jack stand reciprocates, and no transmission gap, smooth movement, and therefore widely used in various mechanical hydraulic system. Hydraulic cylinder output force and the effective area of ??the piston and the pressure is proportional to both sides; consisting essentially of hydraulic cylinders and cylinder head, piston and piston rod, seals, cushioning device component and exhaust. Cushioning device and the exhaust depending on the specific application may be, other devices are essential.
