Product Overview

The Honghua HHF 1000 Pulsation Dampener system includes three key components: the GH3101-27.00 KB-75 Surge Damper, GH3101-28.00A JA-3 Relief Valve, and GH3161-22.00B Elbow Assembly. Our spare parts cover every element of these components, including: surge damper parts ; relief valve parts ; and elbow assembly parts 。All parts match OEM dimensions exactly, ensuring tool-free installation and consistent performance.
Function
The pulsation dampener’s core function is to absorb pressure spikes and stabilize fluid flow from the Honghua HHF 1000 mud pump. It operates through a simple, effective mechanism: the KB-75 Surge Damper’s air bag (GH3101-27.03.00) is pre-charged with nitrogen (3.0–4.5MPa), acting as a cushion to absorb pressure surges. When the mud pump generates high-pressure fluid, the air bag compresses, converting kinetic energy into potential energy; when pressure drops, the air bag expands, releasing energy to maintain consistent flow.
Structural Features
- Durable Air Bag (GH3101-27.03.00): Made from nitrile rubber with a reinforced nylon layer, resistant to drilling fluid corrosion and high pressure (up to 30MPa). It maintains elasticity for 7,000+ operating hours, ensuring consistent pressure absorption.
- Robust Shell Assembly (GH3101-27.04.00): Forged carbon steel construction with anti-corrosion coating, capable of withstanding static pressure up to 35MPa and vibration up to 4g, ensuring long-term structural integrity.
- Precision Pressure Monitoring: The Y-60 Pressure Gauge (0–25MPa) provides accurate readings with ±1% error margin, while the gauge guard (GH3101-27.08.00) protects it from physical damage.
- Reliable Relief Valve (JA-3): Features a shear pin (GH3101-28.11) that breaks at 25MPa to release excess pressure, preventing system over-pressurization. The piston assembly (GH3101-28.03.00) ensures smooth, responsive operation.
- Leak-Proof Connections: Ring gaskets (R39, R27) and 277 sealant create a hermetic seal, preventing fluid leakage even at high pressure. Connectors and T-joints (NPT1/4) ensure secure, compatible fit with the HHF 1000 mud pump.
- Maintenance & Care Recommendations
Proper maintenance ensures the pulsation dampener operates reliably. Follow these practical guidelines:
- Check the air bag pre-charge pressure (3.0–4.5MPa) every 200 operating hours using the charging hose (GH3101-27.11.00) and pressure gauge. Recharge with nitrogen if pressure drops below 3.0MPa.
- Inspect gaskets (R39, R27) every 500 operating hours for wear or leaks. Replace with our compatible parts and apply 277 sealant for a secure seal.
- Test the JA-3 Relief Valve every 1,000 operating hours. Replace the shear pin (GH3101-28.11) if it’s broken, and check the piston assembly for wear.
- Clean the pressure gauge (Y-60) monthly to ensure accurate readings. Replace if it’s unresponsive or shows errors exceeding ±1%.
- Store spare parts in a clean, dry environment (0°C–25°C) to prevent corrosion. Protect air bags from sharp objects and extreme temperatures.

On-Site Fault Maintenance Cases
Case 1: Pressure Fluctuations Due to Air Bag Leak
Scenario: An onshore rig reported severe pressure fluctuations (±8MPa) and increased drill string vibration. The pressure gauge showed erratic readings, and the surge damper was leaking fluid.
Root Cause: The GH3101-27.03.00 Air Bag had a small tear, causing nitrogen leakage and reduced pressure absorption. The air bag had not been inspected for 800 operating hours.
Solution: Replaced the air bag with our compatible GH3101-27.03.00 Air Bag, recharged it to 3.5MPa, and replaced the R39 ring gasket. Pressure fluctuations dropped to ±2%, vibration decreased, and drill string wear was reduced.
Case 2: Relief Valve Failure & Over-Pressurization
Scenario: A rig experienced a fluid end leak after the mud pump pressure exceeded 28MPa. The JA-3 Relief Valve failed to release excess pressure, causing damage to the elbow assembly.
Root Cause: The shear pin (GH3101-28.11) was worn and did not break at the 25MPa setpoint. The valve body (GH3101-28.04) was contaminated with mud, preventing smooth operation.
Solution: Replaced the shear pin, valve body, and buffer pad with our compatible parts. Cleaned the relief valve and tested it to ensure it releases pressure at 25MPa. The elbow assembly was repaired with a new R27 gasket and 277 sealant, restoring normal operation.
Case 3: Fluid Leakage from Elbow Assembly
Scenario: An offshore rig noticed fluid leakage from the GH3161-22.00B Elbow Assembly, leading to reduced pump efficiency and increased oil consumption.
Root Cause: The R27 ring gaskets were degraded by saltwater, and the bolts (GH3161-22.04) were loose, causing a leak. The sealant had dried out and lost its effectiveness.
Solution: Replaced the R27 gaskets, applied new 277 sealant, and tightened the bolts to the recommended torque. The leakage stopped, and pump efficiency was restored to 100%.
FAQ (Frequently Asked Questions)
| Question | Answer |
| Are your spare parts compatible with the Honghua HHF 1000 mud pump pulsation dampener system? | Yes, all our spare parts are 100% OEM-compatible with the Honghua HHF 1000 mud pump pulsation dampener, including the KB-75 Surge Damper, JA-3 Relief Valve, and Elbow Assembly. They match original dimensions and performance standards, requiring no modifications for installation. |
| What is the recommended service life of the GH3101-27.03.00 Air Bag? | Under normal conditions (proper pre-charge, clean drilling fluid), the air bag has a service life of 7,000+ operating hours. For harsh offshore or abrasive environments, we recommend inspecting it every 500 hours and replacing it if signs of wear or leakage are found. |
| How do I test the JA-3 Relief Valve to ensure it works properly? | To test the JA-3 Relief Valve, gradually increase fluid pressure to 25MPa. The shear pin should break, and the valve should release excess pressure. If it doesn’t, replace the shear pin and piston assembly with our compatible parts. We also recommend cleaning the valve body regularly to prevent contamination. |
