Filter element MG00.21.13.01: High-Precision Filtration for Hydraulic System Reliability

As the first line of defense for a high-pressure oil station system, the MG00.21.13.01 inlet filter element plays a vital role. Acting as the system’s "gatekeeper," it effectively intercepts external impurities to protect the safe operation of oil pumps and hydraulic circuits.

Below is a detailed technical translation of its working principles and maintenance highlights.

1. Core Functions: Precision Protection

The primary purpose of the inlet filter is to remove various impurities from the oil before they enter the pump and hydraulic circuits. Its impact is seen in three key areas:

• Intercepting external contaminants: Blocks dust and metal particles from the environment.

• Filtering residual impurities: Removes contaminants inherent in the oil itself.

• Blocking wear debris: Traps particles generated during system operation.

By eliminating these at the source, the filter prevents damage to precision components. In high-pressure oil stations, the fit clearance of components like oil pumps and proportional relief valves is extremely small; even micron-sized impurities can cause valve core sticking or pump scouring.

2. Triple-Design for High-Efficiency Filtration

The MG00.21.13.01 ensures high-level protection through three specific design features:

1. High-Precision Media: Utilizes 10μm filtration material to capture minute particles, fully meeting the NAS1638 Class 8 cleanliness standards required for high-pressure systems.

2. Depth Filtration Structure: Offers high dirt-holding capacity and low flow resistance, ensuring it does not restrict the oil pump’s maximum output of 14.8 L/min.

3. Superior Sealing: Features a tight seal at the inlet, paired with 0Cr18Ni9 stainless steel welded pipe connections to prevent any bypass leakage of impurities.

3. Operational Workflow and System Synergy

Once oil is added to the tank via the air breather, it must pass through the MG00.21.13.01 before entering the pump. The filter acts as a "sieve," allowing clean L-HM46 anti-wear hydraulic oil to pass while trapping contaminants on the surface. Furthermore, this element works in synergy with the duplex filter system, ensuring that even during filter replacement, the oil flow remains uninterrupted, guaranteeing continuous operation of the station.

4. Technical Specifications and Monitoring

The MG00.21.13.01 is designed strictly according to the 20MPa pressure rating of high-pressure oil stations, offering high structural strength and a long service life.

Key Performance Data

The system is equipped with a differential pressure indicator. When the pressure drop across the filter reaches 0.35 MPa, an alarm is triggered to alert maintenance personnel to replace the element, preventing system pressure abnormalities caused by clogging.
