The value of β10 is ≥ 2000, indicating that the filtration effect is high. Additionally, it has a dirt-holding capacity of 180 g, which is 63% higher than similar products in the industry. This means it can trap more contaminants before needing replacement, reducing maintenance frequency and costs.

2. Excellent Fluid Characteristics

The filter element is designed to ensure smooth fluid flow and minimum pressure loss. At 25℃, it has a rated flow of 280 L/min, with an initial pressure loss of ≤0.08 MPa. After accumulated operation for 2000 hours, the pressure loss is still ≤ 0.18 MPa, and the power attenuation of the hydraulic system is ≤ 0.5%. This ensures that the hydraulic system of the excavator maintains the best performance during the whole operation process.

3. High Temperature and Durability Resistance

The 800175537 Main Filter Element can withstand a wide range of temperatures, from -45℃ to 135℃. After 30 high and low temperature cycle tests (-45℃ for 4 hours, and then 135℃ for 4 hours), the integrity and sealing performance retention rate of the filter material is ≥ 98%. In mine – related simulated tests, it has an average Mean Time Between Failures (MTBF) of 2500 hours, indicating its high reliability in harsh working conditions.

4. Solid Structural Strength

The structural integrity of the filter element is very important for its performance. The bonding strength between the end cover and skeleton is ≥ 3.0 MPa, and the bursting pressure is ≥ 4.5 MPa (ISO 2941:2020). After a 200-hour test of 15 g (10-500 Hz) vibration acceleration, there is no delamination or skeleton deformation, ensuring its durability in vibration environment.

5. Accurate Bypass Valve Characteristics

The opening pressure of the bypass valve in the filter element is 0.20±0.02 MPa, and the reset precision error is less than or equal to 3%. At the extremely low temperatures of -45℃, the opening response time is less than or equal to 0.3 seconds, so as to prevent the system from being short of oil due to high viscosity of hydraulic oil in cold start.

Core Component Technology

Gradient Composite Filter Material Assembly

The core filtration layer of the 800175537 Main Filter Element adopts a three-layer gradient structure of “coarse filtration – fine filtration – adsorption”. the outer layer is a polyester fiber coarse filtration layer that intercepts sand and gravel ≥ 50 μm and sealing debris. The middle layer is a high-silica glass fiber fine filtration layer with a 10 μm absolute filtration precision, capturing micron-sized abrasive particles. The inner layer is a nano-magnetic adsorption layer that adsorbs magnetic impurities such as iron oxide and iron filings in the hydraulic oil, achieving dual purification of “physical interception+magnetic adsorption”.

The glass fiber in the material is added with 15% basalt fiber and 10% high-temperature-resistant resin, with a tensile strength of ≥ 1.2 kN/m and a 50% improvement in resistance to hydraulic oil aging. The magnetic adsorption layer is coated with nano-ferrite, and the magnetic adsorption efficiency is 40% higher than that of the ordinary magnetic filter elements.

Magnetic Anti-backflow Check Structure (Patented Core)

Inside the filter element’s cavity, there is an integrated permanent magnet assembly (surface magnetic field strength ≥ 1200 Gs) paired with a “blocking umbrella” check valve at the lower end cap. When the system stops, the check valve automatically closes to prevent the magnetic impurities adsorbed in the cavity of the filter element from flowing back into the hydraulic oil tank. When the system is started, the oil pressure pushes the one-way valve to open, allowing normal hydraulic oil to flow.

The permanent magnet is made of NdFeB alloy (nickel plated on the surface for corrosion resistance), and the check valve disc is made of fluororubber (Shore hardness of 75 A), which has excellent oil resistance and high and low temperature resistance.

Integrated Bypass Valve and Sealing System

The bypass valve is integrated into the upper end cover of the filter element, and adopts a spring-type structure, so that the opening pressure is accurate and controllable, and the hydraulic system is prevented from being short of oil when the filter element is blocked. The spring is made of 304 stainless steel, and its anti-fatigue life is more than 100,000 times.

The upper and lower end covers are made of double-lip nitrile rubber sealing rings (temperature resistance: -45℃ to 120℃), which are matched with a ring groove seal design. When the sealing compression is 30%, under the pressure of 0.4 MPa (ISO 2942: 2019), the leakage is ≤ 1mL/min.

FAQs

Q 1: If the hydraulic system pressure rises abnormally after installing a filter element, how should I troubleshoot the issue?

A: ① Check the installation direction of the filter element (the arrow on the housing must align with the direction of hydraulic oil flow; installing it backward will result in filtration failure and a sudden spike in pressure). ② Clean the upstream coarse filter screen (this component is prone to clogging in high-dust environments and requires periodic removal and cleaning). ③ Check if the bypass valve is stuck (remove the valve and flush it with clean hydraulic oil; if the valve is severely stuck, the filter element must be replaced).

Q 2: What is the standard tightening torque for replacing the filter element?

A: The standard tightening torque is 35 ± 5 N·m. A torque wrench must be used for this operation; insufficient torque can easily lead to seal leakage, while excessive torque can damage the threads on the end cap.

Q 3: How should the filter element replacement interval be adjusted for different operating conditions?

A: ① High-dust mining environments (sand content ≥ 50 mg/L): Replace every 2,000–2,200 hours. ② General mining environments: Replace every 2,500 hours. ③ Infrastructure construction environments: Replace every 2,800–3,000 hours. ④ If the cleanliness level of the hydraulic oil falls below ISO 4406 18/15/12, the filter element must be replaced 500 hours earlier than the standard schedule.

Q 4: Can filter elements be cleaned and reused?

A: Cleaning and reusing filter elements is not recommended. The fiber structure and magnetic adsorption layer of the gradient composite filter material are damaged during the cleaning process, resulting in a filtration efficiency reduction of over 70%. This can lead to excessive wear on the hydraulic pump and directional control valves; the cost of a single repair can exceed 150,000 RMB—far exceeding the cost of purchasing a new filter element.

Q 5: If the hydraulic system is difficult to start in extreme low-temperature conditions, could this be related to the filter element?

A: It may be related. If the bypass valve becomes stuck due to low temperatures and fails to open in a timely manner, the high viscosity of the hydraulic oil can result in insufficient oil supply to the system. Solution: Replace the filter element with the original manufacturer’s part number 800175537 (designed for low-temperature operation down to -45°C), or add an anti-gelling agent to the hydraulic oil to reduce starting resistance.

Q 6: If a leak occurs while the filter element is in use, how can I identify the cause?

A: ① Inspect the sealing ring for signs of aging or damage (it is recommended to replace the sealing ring every two filter element replacements; Original Part No.: 800175537-01); ② Verify whether the end cap is deformed (this is often caused by exposure to high temperatures or overtightening during installation; the filter element must be replaced); ③ Check if the system pressure exceeds 4.5 MPa (excessive pressure can cause the filter element to rupture; the system pressure must be adjusted to within the rated operating range).

Conclusion

As a critical “consumable” precision component within excavator hydraulic systems, the 800175537 filter element directly benefits from the aforementioned industry trends. Selecting a reliable machinery parts supplier is a pivotal decision for equipment managers seeking to reduce costs, enhance efficiency, and safeguard asset value.
