The appearance of the hydraulic wrench should be as small as possible!Air chainsaw manufacturer
source:Industry News release time:2021-11-05 Article author:Rosit Popular:Air band saw
Due to the limitation of the working space, the appearance of the hydraulic wrench should be as small as possible, and the scale value determines the width of the wrench, and the value of d determines the thickness of the hydraulic wrench. This requires that neither of these two values is too large. For larger torque output values, the pressure P of the hydraulic source should be increased as much as possible. This should be considered in the design of the hydraulic source. For a hand-cranked pump, its output pressure P is proportional to the length of the arm and manual action, and inversely proportional to the piston diameter of the hand-cranked pump. In order to obtain high-pressure output, these three The parameters are designed to be weighed to ensure sufficient pressure output, but also cannot require too much artificial force, and the output flow rate must be appropriate.
The hydraulic tensioner is the world's advanced bolt pre-tightening and disassembly tool. The hydraulic bolt tensioner is widely used for the pre-tightening of large-diameter bolts due to its simple operation, convenient use and high safety. Practice has proved that the hydraulic tensioner has little damage to the equipment, the connection components are evenly stressed, and the reliability of the bolt connection is high.
Hydraulic bolt tensioner is abbreviated as hydraulic tensioner, which has the function of bolt fastening and disassembly. It can be widely used in metallurgical mining, petrochemical industry, shipbuilding industry, power system, rolling stock, heavy machinery and other industries. With the help of the hydraulic power provided by the ultra-high pressure pump and the allowable elasticity of the material, the bolt is stretched in its elastic deformation zone to achieve the purpose of tightening or disassembling the bolt. In addition, it can also be used as a device for hydraulic interference connection to apply axial force for top pressure installation. Especially in the working environment with serious pollution or restricted space area, the use of hydraulic stretching device is difficult to replace by any other tools, and it is an ideal process equipment for the assembly of large and medium-sized mechanical products and equipment maintenance. Greatly improve the efficiency of construction work.
