Core Application & User Demand
Exclusively compatible with the Sichuan Honghua HHF-1000 mud pump, the GH3101-22.00 draining filter assembly filters impurities from the pump’s lubricating or hydraulic oil during drainage, preventing component wear and system blockage. It meets the segmented needs of oil drilling, mining, and engineering users for high-efficiency, durable filtration accessories, solving equipment failure risks caused by contaminated oil in high-dust, high-vibration harsh working environments.
Product Classification & Technical Specifications
1. Filtration Core Component
This component is the core of the draining filter, responsible for capturing oil impurities (dust, metal particles). It addresses the pain point of reduced filtration efficiency due to clogging or damage, ensuring clean oil discharge and protecting the mud pump’s internal hydraulic/lubrication components from abrasive wear in harsh drilling scenarios.
No. | Drawing No. | Product Name | Material | Main Wear Causes | Damage Prevention Notes |
1 | GH3101-22.01.00 | Filter screen assembly | Stainless steel 316 (filter mesh: 100 mesh; frame: carbon steel Q235B with anti-corrosion coating) | 1. Clogging from excessive oil impurities; 2. Mesh damage from large metal particles; 3. Frame corrosion from long-term contact with oil and moisture. | 1. Clean with compressed air (≤0.3MPa) every 30 days to avoid clogging; 2. Inspect mesh for tears before reinstallation; 3. Replace if mesh damage exceeds 3mm or clogging cannot be cleared. |
2. Structural & Sealing Components
These components form the filter’s outer structure and ensure sealed operation, preventing unfiltered oil leakage. They comply with GB/T3452.1-1992 standards for O-rings, solving the pain point of oil leakage and impurity bypass, and maintaining structural integrity in high-vibration mud pump operations.
No. | Drawing No. | Product Name | Material | Main Wear Causes | Damage Prevention Notes |
1 | GH3101-22.02 | Shell | Gray cast iron HT250 (surface anti-rust paint + epoxy coating for oil resistance) | 1. Impact damage from construction site debris; 2. Coating peeling leading to corrosion; 3. Crack formation from uneven pressure during installation. | 1. Install a protective cover to avoid impact; 2. Inspect coating integrity quarterly and reapply if peeling; 3. Tighten fasteners evenly to distribute pressure. |
2 | GB/T3452.1-1992 | O ring：165×7G | Nitrile rubber (NBR 70, oil-resistant, temperature-resistant -20℃~120℃) | 1. Aging and hardening from long-term contact with high-temperature oil; 2. Damage from sharp edges during installation; 3. Sealing failure from oil contamination. | 1. Replace every 6 months (compliant with GB/T3452.1-1992 service life standards); 2. Smooth installation edges to avoid cutting; 3. Clean sealing surfaces before installation. |
3. Fastening Components
These components secure the filter assembly, ensuring stable connection under high vibration. They comply with UN/UNF thread standards, solving the pain point of loose fasteners and oil leakage, and providing reliable clamping force to maintain the filter’s structural and sealing integrity during mud pump operation.
No. | Drawing No. | Product Name | Material | Main Wear Causes | Damage Prevention Notes |
1 | GH3101-22.03 | Bolt：1 1/2-8UN （12UNF）-2A×128 | Alloy steel 40Cr (quenched and tempered, surface zinc-plated for corrosion resistance) | 1. Thread wear from repeated disassembly; 2. Fatigue fracture from high vibration; 3. Corrosion from humid and dusty environments. | 1. Torque to 85-90N·m (compliant with UN/UNF 2A thread standards); 2. Apply anti-rust thread lubricant during installation; 3. Replace if thread stripping or corrosion exceeds 25% of the surface. |
2 | GH3101-22.04 | Nut：1 1/2-8UN-2B（SPL） | Carbon steel 10B21 (heat-treated, surface zinc-plated) | 1. Thread stripping from over-tightening; 2. Loosening due to vibration; 3. Corrosion leading to reduced clamping force. | 1. Use torque wrenches to avoid over-tightening; 2. Pair with lock washers for anti-loosening; 3. Inspect and retighten monthly to compensate for vibration-induced relaxation. |
On-Site Fault Maintenance Case
Case 1: Filter Leakage & Reduced Filtration Efficiency
A drilling site reported oil leakage from the GH3101-22.00 draining filter of the Honghua HHF-1000 mud pump, along with increased oil contamination. Inspection found the GB/T3452.1-1992 O-ring was aged and cracked, and the filter screen was severely clogged. Solution: Replace the O-ring and filter screen assembly, retorque bolts to standard specifications, and clean the shell. Post-repair, no leakage occurred, and oil filtration efficiency returned to normal for 7 months of stable operation.
FAQ (Frequently Asked Questions)
No. | Question | Answer |
1 | Can these parts be used for other mud pump models besides Honghua HHF-1000? | No. All parts are custom-engineered for Sichuan Honghua HHF-1000, with dimensions, thread specifications (UN/UNF), and O-ring size matching this model exclusively. Misuse may cause leakage, filtration failure, or equipment damage. |
2 | What is the standard for the O-ring, and why is it important? | The O-ring complies with GB/T3452.1-1992, the national standard for hydraulic fluid power O-rings. This ensures oil resistance, temperature adaptability, and precise dimensional fit, preventing unfiltered oil leakage and maintaining filtration effectiveness. |
3 | How often should key components like the filter screen and O-ring be replaced? | Replace the O-ring every 6 months. The filter screen should be cleaned monthly and replaced every 12 months (or sooner if severely clogged/damaged). Regular replacement avoids filtration loss and protects the mud pump’s hydraulic/lubrication system. |
