Excessive mesh size of the filter can have the following effects on the hydraulic system:

1. * * Easy to clog * *: Due to the small pore size, it is more likely to be clogged by impurities during the filtration process. Once blocked, it can cause obstruction of oil flow and affect filtration efficiency. If the equipment is in operation, it may affect its normal operation, such as causing unstable hydraulic system pressure.

2. * * Low flux * *: Excessive mesh size will slow down the speed of oil passing through the filter, resulting in a decrease in flux. In some scenarios where a large amount of oil needs to pass through the filter quickly, a filter with a high mesh size may not be able to meet the demand because it cannot process a large amount of oil in a short period of time, which may reduce the overall efficiency of the system.

3. * * High cost * *: Generally speaking, the larger the mesh size of an oil filter, the higher its price. This is because producing high mesh filters requires more precise processes and better materials, and their service life may be relatively short due to issues such as easy clogging, thereby increasing the cost of use.

In summary, a high number of filter mesh will have a series of adverse effects on the hydraulic system. Therefore, when choosing a filter, it is necessary to comprehensively consider the specific requirements of the system, filtration efficiency, cost, and other factors to find the most suitable filter configuration.
