Main Valve /Service Valve R200 R210 R215 R220 R225-7 R225-9 Excavator Accessories Relief Valve For Hyundai
About Products:
The following are some ways to determine whether the excavator safety relief valve is working properly:
1. Observe the system pressure: Use a pressure gauge to measure the system pressure to see if it is within the normal range.
2. Check the pressure relief: when the system pressure reaches the set value, observe whether there is pressure relief.
3. Listen for the sound: When operating normally, the pressure relief valve may make a specific sound when it relieves pressure.
4. Check for leaks: Look around the pressure relief valve for signs of leaks.
5. Observe the working performance: Pay attention to whether the working performance of the excavator is normal, such as whether the movement is smooth, etc.
6. Compare devices of the same model: Compare with devices of the same model that are working properly.
7. Check the valve core and valve body: Make sure the valve core and valve body are not worn or damaged.
8. Test multiple times: Test multiple times under different working conditions.
9. Check the pressure regulating device: Confirm whether the pressure regulating device is normal.
10. Check the fault indicator light: If there is a relevant fault indicator light, check its status.
11. Check the hydraulic oil temperature: Excessively high temperatures may indicate a problem with the pressure relief valve.
12. Check other components of the hydraulic system: eliminate the possibility of failure of other components.
If you suspect there is a problem with the pressure relief valve, it is recommended that it be inspected and repaired by professional maintenance personnel.
Production processes:
The manufacturing process of excavator safety relief valve usually includes the following steps:
1. Material selection: Choose high-strength, corrosion-resistant materials, such as alloy steel.
2. Design and Drawing: Carry out detailed design and drawings according to technical requirements.
3. Mechanical processing:
• Valve body processing: including drilling, milling, etc.
• Valve core machining: ensuring accuracy and surface quality.
4. Heat treatment: Improve the strength and wear resistance of parts.
5. Grinding and polishing: Make the surface smooth and reduce leakage.
6. Assembly:
• Install the valve core: ensure flexible movement.
• Assembling other parts: strictly follow the process requirements.
7. Test:
• Pressure Test: Verify the operating pressure range of the pressure relief valve.
• Seal test: Check for leaks.
8. Quality inspection: ensure compliance with relevant standards.
9. Surface treatment: such as electroplating, spraying, etc., to improve anti-corrosion performance.
10. Packaging and shipment: Use appropriate packaging to prevent damage during transportation.
During the entire production process, strict quality control is required to ensure the stable and reliable performance of the pressure relief valve. At the same time, follow relevant standards and specifications to meet safety requirements.
