Products Description

70Mpa Hydraulic Torque Wrench is a bolt fastening and removal tool, with the following features and advantages:
Working principle: It transmits the power generated by the hydraulic pump to the working head through the high pressure oil pipe, and drives the working head to rotate, so as to realize the tightening or loosening of the nut. The working head is mainly composed of the frame (shell), the cylinder and the transmission parts, the cylinder output force, the cylinder piston rod and the transmission part of the motion pair, the distance from the center of the cylinder to the center of the transmission part to form the moment arm, the cylinder output multiplied by the moment arm is the theoretical output torque, but because of the friction resistance, the actual output torque will be less than the theoretical value.
Performance characteristics:
Large output torque: can provide a powerful torque output, can be used to tighten and remove large-diameter bolts, in some scenarios with high bolt torque requirements, such as large mechanical equipment, bridge construction, electric power facilities and other installation and maintenance operations, can efficiently complete the task.
High accuracy: the torque accuracy can usually reach ±3%, which can accurately control the tightening degree of the bolt, ensure the reliability and safety of the bolt connection, and avoid equipment failure or safety hazards caused by too much or too little torque.
Application: 70Mpa Hydraulic Torque Wrench is widely used in electric power (nuclear power, wind power, hydropower, thermal power), shipbuilding, metallurgy, transportation, cement, construction and other industries. For example, in the power industry, bolts used to install and overhaul large transformers, generators and other equipment; In shipbuilding, it is used for the assembly and maintenance of hull structures; In the metallurgical industry, it is used for the installation and maintenance of blast furnace, rolling mill and other equipment.
