Sany And Zoomlion Concrete Pump Skeleton oil seal 60 * 80 * 7 \ 5.5 (for 190 main oil pump)

The skeleton oil seal in the concrete main hydraulic pump A11VLO190LRDU2/11R-NZD12K0 serves an important function in maintaining the integrity and performance of the hydraulic system. Here is a description of the function and role of the skeleton oil seal:

1. Sealing: The primary function of the skeleton oil seal is to provide a reliable and effective seal between moving parts in the hydraulic pump. It prevents the leakage of hydraulic fluid, such as oil, from the pump's internal components. The seal ensures that the pressurized hydraulic fluid remains contained within the pump, preventing loss of pressure and maintaining the efficiency of the pump system.

2. Contamination Prevention: The skeleton oil seal also serves to prevent the entry of contaminants, such as dirt, dust, and moisture, into the hydraulic system. It forms a barrier that keeps external elements from entering and potentially damaging the pump's internal components. By maintaining a clean and contaminant-free hydraulic system, the oil seal helps to ensure the longevity and reliability of the pump.

3. Lubrication Retention: In addition to sealing and contamination prevention, the skeleton oil seal helps to retain lubricating oil within the hydraulic system. It helps to maintain a proper lubrication film between moving parts, reducing friction and wear. This contributes to the smooth operation and extends the lifespan of the pump's internal components.

4. Temperature and Pressure Resistance: The skeleton oil seal is designed to withstand the high pressures and temperatures typically encountered in hydraulic systems. It is made from materials that can withstand the demands of the hydraulic environment without deforming or failing. The seal's ability to maintain its shape and sealing properties under these conditions ensures the reliability and performance of the hydraulic pump.

Overall, the skeleton oil seal in the concrete main hydraulic pump plays a crucial role in sealing, preventing contamination, retaining lubrication, and withstanding high pressures and temperatures. It contributes to the efficient and reliable operation of the hydraulic system, ensuring the longevity and optimal performance of the concrete pump. Proper maintenance and replacement of the oil seal are essential to prevent hydraulic fluid leakage and maintain the integrity of the hydraulic system.
