The wear period of hydraulic wrenches is divided into three stages: initial wear, normal wear and abnormal wear. Many people do not know what to do when they encounter wear of hydraulic wrenches. It is not easy to continue to use. No worries, we still have a solution to the small wear of hydraulic wrenches.
In the initial wear stage, when the hydraulic wrench parts are manufactured, its metal appearance will have some unevenness, so when working, the parts move at high speeds, and it is easy to produce fine friction. This process belongs to the initial wear stage.
When the hydraulic wrench is adapted to the electric pump after a period of running-in, a new and higher-precision roughness is generated during the friction process. At this time, the wear rate is slowed down and a longer period of stable application is entered. It is a normal stage of wear.
In the abnormal wear stage, the service life of metal raw materials has reached and the appearance has also changed. Under the action of high temperature and high pressure, the appearance of metal drops, and the wear time will be long, which will cause the failure of parts.
The hydraulic wrench adapts to the electric hydraulic pump station to produce wear between the related parts of the static pressure bearing during the relative activity in operation, making the cracks between the parts larger, the leakage in the pump increases, and the oil temperature also increases accordingly. The hydraulic wrench transitions from the initial running-in period to the stable application stage and then to the severe wear stage. The length of these three stages mainly depends on the cleanliness of the hydraulic oil. Therefore, the hydraulic oil should be replaced regularly to ensure that the hydraulic oil is used during the use of the hydraulic wrench At the same time, it should also pay special attention to whether the bolt is within the torque limit, to prevent knocking during use.
