Hydraulic torque wrenches are powered by hydraulic pump stations, providing large torque output, used for the installation and disassembly of bolts and nuts, professional bolt locking hydraulic tools, often used to lock and dismantle bolts larger than one inch. The maximum output torque value of the hydraulic torque wrench can reach 160000Nm, which not only provides work efficiency, reduces the labor intensity of on-site operators, but also greatly improves the quality of installation, and is also conducive to on-site safety management!
The use of hydraulic torque wrenches is very wide, in wind power generation, thermal power generation, hydroelectric power generation, nuclear power, shipbuilding, petrochemical, metallurgy, steel structure building, mining, cement and other industries in construction, maintenance, emergency repair and other work, hydraulic torque wrenches are a very important hydraulic tool for the installation and disassembly of large-sized bolts!
The hydraulic torque wrench is not only easy to use and lightweight, but also provides a very accurate torque value, with a torque repeatability of about 3%! According to relevant statistics, 50% of the equipment operation failures are caused by bolt problems, and because the torque of bolt fastening and dismantling is relatively strict in most cases, it is difficult to achieve the required accuracy if you use ordinary wrenches! For large torques, a hydraulic torque wrench is more ideal.
The hydraulic torque wrench working head is mainly composed of three parts, frame, cylinder and transmission parts, cylinder output force, cylinder piston rod and transmission part to form a motion pair, the distance from the center of the cylinder to the center of the transmission part is the hydraulic wrench amplification arm, the cylinder processing multiplied by the force arm, is the theoretical output torque of the hydraulic torque wrench, due to the existence of friction resistance, the actual output torque of the hydraulic torque wrench is less than the theoretical output torque!
Hydraulic torque wrenches have two series: driven hydraulic torque wrenches and hollow hydraulic wrenches! The driven hydraulic torque wrench is used with a standard socket, which is a general-purpose hydraulic wrench with a wide range of uses! The hollow hydraulic torque wrench has a thin thickness, especially suitable for places where space is relatively tight!
Hydraulic torque wrenches are widely used in electric power (nuclear power, wind power, hydropower, thermal power), shipbuilding, metallurgy, transportation, cement, construction, aviation and other fields.
Because the hydraulic torque wrench is often used in the construction process of small spaces and very inconvenient transportation, the volume and weight of the hydraulic torque wrench are the most important indicators! In order to reduce the size of parts, it is common to use high-strength alloy materials and heat treatment!
