DRLF large flow rate return line filter series
Introduction to DRLF large flow rate return line filter series
The DRLF series high flow return oil pipeline filter is mainly installed at the hydraulic system return oil pipeline to filter out impurities such as metal powder and rubber caused by component wear in the oil, ensuring that the oil flowing back to the tank remains clean. The filter element of this filter is made of synthetic fiber filtering material, which has various advantages, such as high filtration accuracy, large oil flow capacity, small original pressure loss, and large pollutant capacity.

Characteristics of DRLF large flow rate return line filter series
1. High filtration accuracy: The DRLF large flow rate return line filter series adopts advanced filtration technology, which can effectively filter out small impurities in the oil and ensure the normal operation of the hydraulic system.
2. Large oil flow capacity: This filter has a large oil flow capacity, which can meet the needs of high flow hydraulic systems, reduce system pressure loss, and improve system efficiency.
3. Small original pressure loss: Due to the use of high-quality materials and advanced manufacturing processes, the DRLF large flow rate return line filter series has a smaller original pressure loss, which helps to reduce system energy consumption.
4. Large pollution capacity: The filter element of the filter adopts a high pollution capacity design, which can accommodate more impurities, extend the service life of the filter element, and reduce maintenance costs.

Performance of DRLF large flow rate return line filter series
1. Equipped with differential pressure transmitter and bypass valve: When the filter element is blocked to a certain extent, the differential pressure transmitter will send a switch signal to remind operators to clean or replace the filter element in a timely manner. If the machine cannot be shut down in a timely manner or no one comes, replace the filter element, and the bypass valve will automatically open to protect the system from damage.
3. Check valve design: When the filter is placed on the side and bottom of the fuel tank, the check valve can prevent oil from flowing out of the tank when replacing the filter element.
4. Liquid flow diffuser: The filter is equipped with a liquid flow diffuser, which can allow the return oil to flow smoothly into the oil tank, reduce the generation of bubbles, reduce the possibility of air re entering the system, and weaken the disturbance of deposited pollutants.
5. Visual indication and electrical signal two in one transmission device: When the filter element is gradually blocked, the operator can observe the blockage of the filter element on the visual gauge, and can also connect to the electrical signal (with a signal value of 0.35MPa).

Scope of use of DRLF large flow rate return line filter series
The DRLF series high flow return oil pipeline filters are widely used in hydraulic systems in heavy machinery, mining machinery, metallurgical machinery, and other fields, providing strong guarantees for the normal operation of these equipment.
