The hydraulic wrench consists of the power head, the working head, the special pump of the hydraulic wrench and the high pressure oil pipe, and the quick joint. Through the high-pressure oil pipe, the hydraulic pump transfers the power to the working head and drives the screw nut of the working head to tighten or loosens.
Power head cylinder output force, cylinder life
The piston rod and the drive part consist of a moving body. The distance between the center of the cylinder and the center of the drive part is the arm of the hydraulic wrench. The output of the cylinder is multiplied by the force arm, which is the theoretical output torque of the hydraulic wrench. Due to the existence of frictional resistance, the actual output torque of the hydraulic wrench is less than the theoretical output torque.
Hydraulic wrench is divided into two categories: square hollow hydraulic wrench, hydraulic wrench. The head of hydraulic wrench with standard sleeve used for a wide range of general-purpose hydraulic wrench; the thickness of the hollow hydraulic wrench is thin, especially suitable for relatively small space of the place. It is suitable for electric power (nuclear power, wind power, hydropower, thermal power and so on).
With hydraulic wrench features: the use of high-tech aerospace materials and ultra high strength alloy steel unibody, strengthen the body strength and toughness pipe joints 360 * 180 degrees rotation, without space restrictions, free operation; the trigger button, easily pressed, can arbitrarily be 360 degrees to fine tune reaction arm due to strong fulcrum; the precision ratchet, precision up to + 3%. Hollow hydraulic wrench features: square with ultra high strength lightweight metal, thin design, double acting, high speed, large angle clamping type, interchangeable plug-in, without special tools, torque repeat precision up to + 3%, rotary hose joint 360 * 180 DEG, suitable for compact occasions to facilitate positioning, wrench strength design fully overall, reaction arm, moving parts, less durable, reliable, scalable metric and inch six angle plug and socket, can realize a dynamic head equipped with multiple plug-ins.
