Hydraulic wrench is a flexible operation, easy to use hydraulic tools, can bring a lot of convenience for machining. In the daily use, due to improper operation method will also be a machine failure, affecting the performance of hydraulic wrench play, making the device can not play the greatest value. So those operations will affect the performance of equipment to play, as engineers have to understand the necessary knowledge.

First, improper operating methods, resulting in hydraulic wrench failure. For mechanical maintenance, according to the operating environment to correctly determine the size of the output torque, if the operation does not understand the principle of hydraulic wrench operation, it will cause the hydraulic wrench operation failure.

Second, the hydraulic wrench maintenance is not guaranteed. In the use of hydraulic wrenches, experienced master will generally be a simple check to understand whether the corresponding problem of hydraulic wrench, but many people do not care when using the maintenance or ignore the hydraulic wrench maintenance, this will cause the use of the process The hydraulic wrench is damaged.

Third, the daily maintenance and maintenance of the cycle is not in place, there is no timely lubrication or damage to parts replacement, resulting in the use of hydraulic wrench failure.

In general, the hydraulic wrench safe operation need to be familiar with the relevant information, and make routine maintenance, familiar with the working principle of hydraulic wrench, so that in the event of failure to deal with in a timely manner, so as to allow its maximum value.
