800159455 Oil Return Filter Element 803409590 XE15U XE17U Hydraulic Filter Element

Product Description:

In industrial hydraulic systems, hydraulic oil is like blood, and its cleanliness directly affects the "health" and lifespan of the entire system. The hydraulic return oil filter element is the last and crucial line of defense to protect this cleanliness. It is usually installed in the return oil pipeline of hydraulic systems, responsible for capturing various pollutants carried in the oil returning to the oil tank after work.

From the product details, the structural design of the hydraulic return oil filter element is precise. Its core is the filtering material, commonly including glass fiber, metal mesh, and composite filter paper. These materials undergo special processing to form a filter layer with a large number of micro pores, which can effectively intercept solid particles. The interior of the filter element is usually supported by a metal skeleton to ensure that it will not collapse under the action of oil pressure. The two end cover plates are made of metal or high-strength engineering plastic, and are tightly matched with the filter housing through special sealing rings (such as O-rings) to prevent oil from "short circuiting" without filtration. The size and interface form of the filter element (such as threaded connection, flange connection) have been standardized in design to adapt to different types of filter housings.

Features:

1. Using multi-layer composite glass fiber or stainless steel filter materials, the filtration accuracy is usually 5-20 microns, which can effectively capture pollutants such as metal debris and rubber particles. The single filtration efficiency can reach over 99%, significantly extending the life of hydraulic oil and components.

2. The 20 filter element design has sufficient filtration area, with low resistance when oil passes through. The initial pressure drop usually does not exceed 0.08MPa, ensuring smooth oil return to the system without affecting the efficiency of the main pump and system response speed.

3. When the filter element is clogged and the pressure difference rises to the set value (such as 0.35-0.4MPa), the bypass valve automatically opens, allowing the oil to return directly to the tank without filtration. This is to prevent the filter element from crushing or causing greater damage due to a lack of oil in the system, which is a safety design. However, the filtering function is temporarily disabled when turned on.

4. An optional differential pressure transmitter can be installed. When the differential pressure reaches the warning value (such as 0.2-0.35MPa), an electrical signal or visual prompt (such as a red indicator column popping up) can be sent to remind the operator to replace the filter element in a timely manner and avoid the system being in a bypass state for a long time.

5. The filter element is supported by a metal frame inside, which can withstand pressure impact and pulsation in the return oil pipeline. The material of the end cap and seal is oil resistant and temperature resistant, with a working temperature range of usually -30 ℃ to+120 ℃. It is compatible with various hydraulic oils, fire-resistant oils, and water ethylene glycol media.

6. The filter element with a straight back design is installed at the top of the fuel tank. When replacing, simply unscrew the cover to pull out the old filter element and insert the new one. The operation is simple and not easy to spill oil. Some models are equipped with self sealing valves, which can automatically close the oil tank and oil circuit when the filter element is removed, preventing oil leakage, which is both clean and economical.
