Conventional hydraulic wrench sets are generally composed of hydraulic wrench body, hydraulic wrench special pump station and double high pressure hose and high strength heavy duty sleeve. Hydraulic wrench special pump can be electric or pneumatic two kinds of drive.

Hydraulic wrench is widely used in Marine engineering, petrochemical, wind power, hydropower, thermoelectricity, mining, machinery, steel mills, rubber, pipelines and other industries in the construction, maintenance, repair and other work, hydraulic torque wrench for the installation and disassembly of large specification bolts are an important tool; There are other tools irreplaceable, not only easy to use, and the torque provided is very accurate, torque repetition accuracy of ±3% or so. Choose and buy hydraulic wrench strategy has: first to choose and buy according to the different specifications of the bolt, there are generally several specifications, such as M36, M42, M48, if you do not say how big the nut, is the metric bolt nut pair with the opposite side of the sleeve, M36 in the nut hexagon is 55, M42 is 65, M48 is 75. If bolt specification span is too large, and torque span is large, then preload these bolts are bound to choose two types of spanner.

Followed by bolt torque, tesco factory remind you: the specifications of the bolt, the bolt strength grade is the most key parameters on the selection of hydraulic torque wrench, bolt, torque is different, the same bolt strength grade different torque, the same bolt strength grade and different working condition of the torque is different also, used for rolling mill equipment and chemical equipment bolt torque is not the same, the general design drawings will be given torque size, such as not to give, give the corresponding standards, such as heavy machinery equipment is the gb, JB/T5000.10-2007, such as a 8.8 magnitude of M42 bolt torque of 2744 nm; The torque of M36 bolt is 1764Nm; The torque of M48 bolt is 3920Nm; Above three kinds of bolts can choose a type of wrench.

If there is no space limit, any type of spanner can be used; Drive type hydraulic wrench is the most economical; If the screw thread is longer or there is limited space above the bolt, it is better to use a hollow hydraulic wrench; If the distance between nuts is narrow, hollow hydraulic wrench can be used
