The hydraulic cylinder sealing kit is an important component in the hydraulic system, used to prevent hydraulic oil leakage and protect the pistons and rods inside the hydraulic cylinder.

The main cause is the random vibration signal. It is generally possible to have these three frequency structures in the power spectrum of a normally operating gearbox, but the amplitude is relatively small. With the occurrence of gear failure (such as gear wear), if the linear spectrum gear is faulty during operation, the temperature, the content and shape of the wear in the lubricating oil, the vibration of the gearbox and the noise of the radiation, some signs are extracted. It is not easy to achieve with analysis, and some conditions reflect the state of the situation is not sensitive.
Choosing the correct hydraulic cylinder sealing kit can extend the service life of the hydraulic system and improve work efficiency.
The following are some key points for purchasing a hydraulic cylinder sealing kit:
1. Determine the model and specification of the hydraulic cylinder: The size and model of the hydraulic cylinder sealing kit must be completely matched with the hydraulic cylinder, otherwise it may cause poor sealing or damage to the sealing components.
2. Choose appropriate sealing materials: The sealing materials for the hydraulic cylinder sealing kit should be selected based on factors such as the type of hydraulic oil, temperature, pressure, etc. The commonly used sealing materials are fluororubber, Butyl rubber, polyurethane, etc.
3. Choose a reliable supplier: Choose a legitimate hydraulic cylinder sealing kit supplier to ensure product quality and after-sales service.
4. Pay attention to installation and maintenance: Proper installation and maintenance of the hydraulic cylinder sealing kit can extend its service life and reduce maintenance costs.
The following is a description of the commonly used analysis method - power spectrum analysis. Power spectrum analysis can determine the frequency composition of the gear vibration signal and the distribution of vibration energy in each frequency component. It is an important frequency domain analysis method. There are generally three kinds of frequency structures in the power spectrum, which correspond to different reasons, as shown in Figure 1. A port crane hoisted a strong vibration during the earthwork. Initial inspection found that during the lifting process, if a hoist was started, one of the gearboxes vibrated the most.
