Detailed introduction of product materials
0500D020BH3HC is a large-sized high-pressure filter element, which focuses on enhancing the structural reliability under high flow fluid impact. The entire set of materials is benchmarked against the original BH3HC high-pressure filter material standard:
-Filter material: high-pressure multi-layer gradient resin bonded glass fiber, with a large unfolded filter material area, balancing 20 μm filtration accuracy and large oil flow rate; The high-pressure solidification process of the filter material ensures that it does not crack or shed fibers under high flow and high-pressure fluid flushing, and has a large pollutant holding capacity, suitable for high displacement hydraulic system pollutant loads.
-Internal and External Skeleton: A large-sized thickened punched metal skeleton is used to enhance the anti extrusion strength for high flow and high pressure conditions, resist high pressure differentials, prevent the filter element from being flattened, deformed, and ineffective. The skeleton has a high opening rate and reduces flow resistance.
-Sealing rubber ring: Large diameter NBR nitrile rubber sealing ring, tightly sealed under high pressure conditions, preventing high-pressure oil leakage; FKM fluororubber seals can be upgraded for high-temperature special working conditions.
-End cap structure: enlarged specifications and thickened metal end caps, high-pressure special hot pressing composite bonding process, high bonding strength between filter material and end cap, able to withstand high flow fluid impact without delamination, and installation positioning dimensions are completely consistent with the original.
Main applicable scenarios and industries
0500D020BH3HC specializes in high flow and high pressure pipeline filtration, commonly used for outlet protection of large displacement hydraulic pumps:
-Metallurgical industry: Large hydraulic stations in steel mills, high-pressure filtration at the pump outlet of the main hydraulic system in rolling mills
-Mining Heavy Industry: Main Hydraulic High Pressure Oil Circuit Protection for Large Mining Equipment and Large Shield Tunneling Machines
-Power industry: High voltage hydraulic system for large auxiliary equipment in power plants, high-pressure circuit for lubricating oil
-General Industry: Large scale centralized oil supply hydraulic systems, high-pressure pipelines for large injection molding units
-Other fields: Large flow hydraulic systems for complete chemical equipment, large hydraulic test benches
Core advantages of the product
1. Integrated performance of high pressure and high flow: With a high pressure tolerance of 21MPa, it can achieve a large oil flow rate and adapt to the outlet of a large displacement hydraulic pump, without causing additional back pressure burden on the system.
2. 20 μm high-efficiency pre protection, protecting the main hydraulic components: intercepting large particle wear impurities in advance, protecting the main pump, hydraulic motor, and various directional valves, and reducing the probability of major equipment failures.
3. Large pollutant holding capacity, extended replacement cycle: The filter material has a large unfolding area, accommodating a high total amount of pollutants, reducing the frequency of large-scale equipment shutdown and replacement.
4. Strengthen the large-scale high-pressure structure and resist fluid impact: the skeleton and end caps are optimized for high flow and high-pressure conditions to avoid filter flattening and delamination under high pressure.
5. Directly replace imported components in situ: The size interface is 100% compatible with the original high-pressure filter, making it easy to disassemble and assemble on site without the need to modify the high-pressure pipeline.
Core advantages of source factory substitution
Our factory has the ability to complete the processing and testing of large-sized high-pressure filter cartridges, fully understanding the economic losses caused by the failure of high-pressure filter cartridges in large equipment. Our quality control standards are strict:
-Benchmarking the original high-voltage process, sampling pulse withstand voltage testing: Referring to the HYDAC D series technical manual and implementing the ISO2941 testing standard, each batch of large-sized high-voltage filter cartridges is subjected to withstand voltage and pulse pressure difference sampling to ensure the reliability of high-voltage working conditions.
-Direct supply from the source factory, controllable procurement cost of large-sized accessories: eliminating the premium of imported brands, with prices far lower than the original, suitable for factory maintenance and bulk bidding procurement of engineering projects.
-Full process quality control, traceable quality: filter material incoming inspection, production control, finished product sampling and testing, and testing records can be provided as needed for large-sized high-pressure filter cartridges.
-Support customized working conditions: materials can be customized for high temperatures and special media.
Frequently asked questions
Q1: What is the reason for the rapid increase in pressure difference of large-sized high-pressure filter cartridges?
A: Prioritize investigating the sources of internal pollutants in the system; The filter element itself has been enlarged to accommodate pollutants, and under normal operating conditions, it can reach its designed lifespan. If the pressure difference reaches 0.5MPa, it should be replaced in a timely manner.
Q2: Can the D series high-pressure filter be directly used as a return oil filter?
A: Physically, it can be installed, but not recommended; The cost of high-pressure filter element is high, and R series return oil filter element is preferred for oil return scenarios, with higher cost-effectiveness.
Q3: What are the key indicators to pay attention to when using large-sized high-pressure filter cartridges?
A: Focus on monitoring the differential pressure of the filter element and the peak pressure of the system, and strictly prohibit long-term operation beyond the system design pressure to avoid instantaneous pressure pulse damage to the filter element.
Q4: Apart from HYDAC filter cartridges, what other oil filtration products do you have?
A: Our factory has a complete product line for oil filtration. In addition to HYDAC replacement filters, we also produce PALL, PARKER, and Leemin series hydraulic filters, which are matched with mobile oil filters and coalescence dehydration filters to achieve integrated filtration of oil impurities and water.
Q5: What other filtering categories does the factory produce?
A: The source manufacturer covers industrial oil filtration, industrial water filtration, natural gas filtration, air filtration, and can produce imported replacement filters, domestic standard filters, and complete sets of filtration equipment. It supplies to multiple industries such as power, metallurgy, chemical, and gas.
