Hydraulic filtration tanks


Hydraulic filtration tanks, or hydraulic filters, are key components in hydraulic systems that work to remove harmful particles by forcing hydraulic oil through a porous filtration element. These filter elements trap contaminants, preventing them from re-entering the fluid flow and damaging other equipment downstream.


The position of the hydraulic filtration tanks in the hydraulic system can be adjusted as needed to capture contaminants generated at different points. For example, a suction filter is typically placed at the pump inlet to ensure that no contaminants enter the pump. Pressure filters, on the other hand, have a high-pressure capability that removes internal contaminants generated within the system, protecting individual components.


When using hydraulic filtration tanks, you need to pay attention to the following points:

1. Regularly check and replace the filter: With the growth of the use time, the filter will gradually clog, affecting its filtration effect. Therefore, it is necessary to check the status of the filter regularly and replace the filter as needed.

2. Keep the filter box clean: The inside of the hydraulic filter box should be kept clean to avoid the entry of dust and impurities. At the same time, the tightness of the filter box should be checked regularly to ensure that there is no leakage.

3. Follow the operating procedures: When replacing the filter or carrying out other maintenance work, it should be carried out in strict accordance with the operating procedures to avoid equipment damage or safety accidents caused by improper operation.


Regularly inspecting and replacing the hydraulic filter box is a key step to ensure the proper operation of the hydraulic system, let's take a look at how to check and replace the hydraulic filter box.

1. Inspection cycle: First, determine the appropriate inspection cycle. This usually depends on how often the hydraulic system is used, the operating environment, and the degree of contamination of the hydraulic fluid. In general, it is advisable to have check-ups at regular intervals (e.g., weekly, monthly, or quarterly).

2. Prepare tools: Prepare the required tools, such as gloves, wiping cloths, screwdrivers, new filter elements, etc. Make sure you have the appropriate replacement filter and that its specifications match the filter currently in use.

3. Close the system: Before checking and replacing the filter, make sure that the hydraulic system has been completely shut down and the pressure has been released. This can be achieved by closing the relevant valves and switches.

4. Disassemble the old filter: Open the lid or panel of the hydraulic filter box to find and remove the old filter. This usually involves loosening the fixing bolts or clips and then carefully removing the filter from the system.

5. Check the inside of the filter box: After taking out the old filter, check the inside of the hydraulic filter box. Watch for unusual wear, corrosion, or dirt. If a problem is found, it should be cleaned or repaired in a timely manner.

6. Install the new filter: Install the new filter into the hydraulic filter box. Make sure it's properly aligned and secured in place. Install according to the manufacturer's instructions or as directed in the device's manual.

7. Cleaning and sealing: After installing the new filter, clean up any residue or dirt in and around the filter box. Then, reinstall and seal the filter box lid or panel to make sure there are no leaks.

8. Restart the system: After completing the above steps, restart the hydraulic system. Make sure the filter is working properly and check the system for any abnormalities or leaks.


Hydraulic filtration tanks are an indispensable part of the hydraulic system, and the proper use and maintenance of hydraulic filtration tanks is of great significance to ensure the normal operation of the hydraulic system.
