Use of hydraulic wrench on construction machinery Posted by : admin / Posted on : Nov 26, 2021

Construction machinery is an important part of the equipment industry. The mechanical equipment necessary for comprehensive mechanized construction projects required for earth and stone construction projects, road construction and maintenance, mobile lifting and loading and unloading operations and various construction projects are mainly used for national defense construction projects, transportation construction, energy industry construction and Production, mining and other raw materials industrial construction and production, agriculture, forestry and water conservancy construction, industrial and civil construction, urban construction, environmental protection and other fields.

The application of hydraulic puller tensioner in construction machinery can save a lot of manpower and material resources. Overcoming the pressure relief of the pressure relief valve when the traditional pump reaches the torque, the pump continues to work, resulting in back pressure in the oil circuit, which is easy to kill the wrench. Equipped with a reset button to prevent jamming during work and affect work efficiency. Another: The pump stops automatically when the torque is reached, which solves the problem of wrench death caused by the back pressure in the system.

The use of hydraulic wrench on construction machinery can ensure the safety of personnel and equipment, and its triple protection device can prevent potential safety hazards caused by improper operation. The hydraulic wrench is very convenient to use and simple to operate. Digital adjustment of hydraulic pump station, torque setting and change is very convenient. Tighten automatically, and automatically stop working when the set torque is reached.

The work efficiency is high, the hydraulic wrench automatically switches the shuttle valve to realize the conversion between the oil circuits and accelerate the advance and retraction of the oil cylinder. A digital pressure switch is used to control the work of the motor and hydraulic pump. When the set pressure and torque are reached, the pump stops automatically, thus avoiding the increase of oil temperature caused by the pressure relief of the hydraulic valve, thus ensuring long-term continuous work.
