There are two types of hydraulic wrench, one is a hollow hydraulic wrench, and the other is a drive hydraulic wrench. We usually use drive hydraulic wrench will be more, therefore, the hollow hydraulic wrench is not very clear. In order to make you better use of the hollow hydraulic wrench, the following Xiaobian will introduce it to you.
First, the application range of hollow hydraulic wrench
1, the hollow hydraulic wrench can be in the transportation, energy, chemistry, metallurgy and other industries in the assembly of mechanical equipment, in the maintenance work, the connection of some key bolts installation and disassembly, can be very convenient and fast to help us complete the installation and disassembly of bolts.
2, some bolts in the space is very small space can not use the length arm, or can not be tightened by the hammer method to disassemble the bolts.
3. Some equipment is used in places with more moisture for a long time, and the bolts are too corroded to be manually disassembled, so the maintenance is difficult. This requires the use of hollow hydraulic wrench.
4, in the air structure and high-altitude equipment structure, because the staff is difficult to use the safety belt, even if the belt is difficult to force, it is difficult to safely complete the work. This can also be done using a hollow hydraulic wrench.
5, according to the statistics of the relevant departments of equipment management, more than half of the equipment failure is caused by bolt problems. It is also alarming that the number of major equipment accidents caused by bolt problems is very high, so the new equipment installation and maintenance specifications require more stringent torque bolt fastening, which better ensures that the desired torque value is difficult to achieve with manual methods.
