Hydraulic wrench with drive hydraulic torque wrench and hollow hydraulic wrench two series. Method of hydraulic wrench generally uses high strength alloy materials and heat treatment to reduce component size and weight of the. Driving hydraulic torque wrench with the use of standard sleeve, which is universal hydraulic wrench, applicable to a wide range of. The thickness of the hollow hydraulic wrench is thin, particularly applicable to space is narrow. Applicable to electric power (nuclear power, wind power, hydropower, thermal power, metallurgy, ship), transportation, cement, construction, aviation and other fields.
The characteristics of hydraulic wrench:
● unibody, ultra high strength light metal, to comprehensively strengthen the body strength, toughness;
● tubing joints 360o × 180o rotation, without space restrictions, free operation;
● trigger type lock easily pressed, can arbitrarily be 360o trimmer type reaction arm positioning in the strong support;
● 采用精密棘輪，精度高達±3% ；
● adopt precision ratchet, high precision is up to ± 3%;
Reverse the check pawl prevent the unique, overcome bolt deformation wrench reversal phenomenon rebound led, can realize hydraulic wrench two or four synchronous operation;
The gas hole design, can continuously work for a long time.
The characteristics of hollow hydraulic wrench:
The integrated power head, using ultra high strength metal, and comprehensively improve the strength and life;
● a power head can be equipped with a variety of working head, wide working range;
● tubing joints 360o × 180o rotation, the closest non tubing design, completely without space restrictions;
The working head all inclusive design, best security, ultra light, ultra-thin, large torque, adapt to the "difficulty" of space.
目前，尋找到高強度材料的難度并非很大， 對于希望部件強度達到1000MPa以上并且穩定，并且對于材質強度的均勻性也要求極高（主要是由于液壓方驅扳手內部零件的不規則所影響），目前國內企業還很難對于液壓方驅扳手內部零件的強度達到 1000MPa以上，即使能個別達到，也很難達到液壓扳手批量的穩定性。還需要多向國外同類產品學習，在一個較長的時期內，投入較多的人力與資金，在材質與熱處理的方面多加以摸索和實驗。
At present, the difficulty of finding high strength material is not great, hope for the parts strength above 1000MPa and stable, and also the requirements for uniformity of material strength (mainly due to the irregular hydraulic driving wrench the internal parts of the affected), in our country enterprise is difficult for the internal parts of the hydraulic driving spanner strength more than 1000MPa, even if the individual to achieve stability, it is very difficult to achieve mass of hydraulic wrench. Also need to change the foreign products of the same kind of learning, in a longer period of time, manpower and money more, in the material and heat treatment many aspects to explore and experiment.
