When purchasing hydraulic oil filters, a number of important factors should be considered to ensure the effective operation and long-term maintenance of the system. Here are some of the main considerations:
1. Filtration accuracy of hydraulic oil filters
When selecting a filter, you must ensure that its filtration accuracy can meet the requirements of the system. Filtration accuracy refers to the minimum particle size that the filter can intercept. For precision equipment, such as servo valves or proportional valves, high-precision filters are needed to avoid particles entering sensitive parts and causing damage.
2. Traffic requirements
The filter selected must have sufficient flow to adapt to the needs of the system and avoid a drop in system pressure or performance due to insufficient flow. The flow rate of the filter should match the flow rate of the pump and the working pressure of the system.
3. Filter material of hydraulic oil filters
The material of the filter directly affects its service life and maintenance cycle. Common filter materials include metal mesh, chemical fiber, glass fiber, etc., of which glass fiber usually has better filtration effect and corrosion resistance.
4. Installation method of hydraulic oil filters
Select the appropriate filter type (such as oil suction filter, pressure filter or return oil filter) according to the system design, and ensure that it is correctly installed, especially the direction of the inlet and outlet should be correct to prevent misoperation leading to system failure.
5. Maintenance and replacement
Considering the ease of maintenance and replacement, it is important to choose a filter model that is easy to replace the filter element, especially for production lines that cannot be easily shut down. Check and replace the filter element regularly to keep the hydraulic system clean and efficient.
6. Environmental adaptability of hydraulic oil filters
Consider the special requirements of the working environment, such as high temperature, high humidity or corrosive chemicals, select the filter designed for the corresponding environmental conditions to ensure the performance and durability of the filter.
