[Abstract]:
Perhaps there are many manufacturers have encountered such a problem, in the use of a period of time, the hydraulic cylinder presents the problem of leakage. For this case, if the choice of maintenance, may need to spend a lot of money, in fact, as long as we can replace the seal ring, you can solve the problem. Let's talk about the replacement procedure. First of all, we need to carefully check whether the new seal ring is abnormal, mainly to see whether the appearance of its Flash, Burr, cracks, trimming, porosity or porosity and other defects. Secondly, it is necessary to ensure that its geometric size and accuracy are satisfied with the operation of hydraulic cylinder requirements. It should be noted that, in general, if the hole with a combination of seals, which mainly include o-ring and wear ring. As we all know, in general, the o-ring is very elastic, so in the device can be relatively easy to finish. However, the elasticity of the wear-resistant ring is poor, so in the device at the time of the need to be careful not to damage, so as not to affect the hydraulic cylinder sealing effect. At this point we need to take certain measures to avoid its damage. Generally speaking, the wear ring is mainly made of polytetrafluoroethylene material, so we can put it into 100 °C oil for 20 minutes to make it gradually soft, and then the device. Obviously, different standard seals in the device at the time, needs to use different tools to complete, so as to ensure the role of the device. After the device is installed, it is necessary to see if the application requirements can be satisfied. It should be noted that the top of the seal ring shall not be wrinkled, distorted, scratched, more not allowed to install the reverse. Of course, in practice to replace the time, we will find that there are some other categories of seals, but no matter which type of seals, we should pay attention to the replacement of time, in accordance with the correct order to operate, ensure excellent sealing, ability to ensure the normal operation of hydraulic cylinder.
