The use of filters in hydraulic systems is crucial, mainly for the following reasons:
1、 Protect system components
During the operation of hydraulic systems, various impurities such as metal particles, dust, sludge, etc. are inevitably generated or mixed in. If these impurities are not filtered in a timely manner, they can cause wear and tear on precision components such as hydraulic pumps, motors, valves, and even lead to component jamming or failure. The filter effectively protects system components and extends their service life by intercepting these impurities.
2、 Ensure stable operation of the system
Impurities not only wear down components, but may also block pipelines and throttling holes, affecting the flow and pressure control of hydraulic systems, leading to a decrease in system performance or failure. Filters can maintain the cleanliness of the oil, prevent blockages, and ensure the stable operation of the hydraulic system.
3、 Improve system efficiency
Clean oil helps reduce internal leaks and friction, lower system energy consumption and heat generation. Filters help maintain the excellent performance of oil by filtering impurities in the fluid, thereby improving the overall efficiency of the hydraulic system.
4、 Monitoring and diagnostic functions
During the filtration process, the filter will accumulate pollutants in the system. By analyzing these pollutants, the wear and tear of system components can be determined, the operating status of equipment can be monitored, potential faults can be detected in a timely manner, and a basis can be provided for equipment maintenance and upkeep.
5、 Filter type and selection
There are various types of filters used in hydraulic systems, which can be classified into coarse filters, fine filters, etc. according to their filtration accuracy; According to the structural form, it can be divided into mesh type, wire gap type, paper core type, etc. Choosing a suitable filter requires consideration of factors such as system pressure, flow rate, oil viscosity, as well as the requirements for filtration accuracy and flow capacity.
