Hydraulic wrench has driven type hydraulic torque wrench and hollow hydraulic wrench series. Hydraulic wrench generally adopt the method of high strength alloy material and heat treatment to the size and weight of the parts is reduced. Drive type hydraulic torque wrench used with standard socket, as the universal hydraulic wrench, wide application scope. With thin thickness of the hollow hydraulic wrench, especially suitable for the space is narrow. Applicable to electric power (nuclear power, wind power, hydropower and thermal power), shipbuilding, metallurgy, transport, cement, construction, aerospace and other fields.
Driven by hydraulic wrench features:
A integrated fuselage, using high strength light metals, comprehensively strengthen body strength and toughness;
Low to 360 x 180 o o rotary tubing connector, without the use of space limitation, free operation;
Low lock easily press the trigger type, can be fine-tuning will follow one's inclinationsly 360 o type reaction arm positioning on the strong team;
Using precision ratchet, precision up to + / - 3%;
Unique plugging check pawl, overcome the bolt deformation caused by springback wrench reversal phenomenon, which can realize hydraulic wrench two synchronous or four synchronous operation;
Lubrication design, can work long time.
The characteristics of the hollow hydraulic wrench:
A integrated power head, using high strength metal, comprehensively improve the strength and life;
When a power head can be equipped with a variety of working head, wide scope of work;
Low to 360 x 180 o o rotary tubing connector, the closest no tubing design, completely without using space limitations;
Best work head all inclusive design, security, super light, thin, large torque, to adapt to a variety of "difficult" space.
, looking for to the difficulty of the high strength material is not very big, to hope to achieve more than 1000 mpa components strength and stability, and to the uniformity of material strength is highly demanding (is mainly due to the hydraulic drive wrench is influenced by the irregular internal parts), the current domestic enterprises is difficult to the strength of the internal parts for hydraulic drive wrench reached more than 1000 mpa, even can achieve individual, it is hard to achieve the stability of hydraulic wrench in bulk. You also need to learn a lot from the same products abroad, in a long period of time, put in more manpower and money, in terms of material and heat treatment of how to grope and experiment.
