2. Core Features
• Structural Advantages:
• Compact Design: External gear configuration for minimal size and weight, ideal for space-constrained installations.
• High-Pressure Resistance: Optimized sealing design to withstand high-pressure conditions and minimize leakage risks.
• Contamination Tolerance: Operates reliably even with lower hydraulic fluid cleanliness levels, suitable for harsh environments.
• Performance Parameters:
• Rated Pressure: Typically200–250 bar(model-dependent), with some variants reaching280 bar.
• Speed Range: Suitable for medium-to-high speeds, with rated speeds of1,600–4,000 rpm. Minimum stable speed recommended:≥500 rpm(to avoid pulsation).
• Displacement: Range of0.16–99 cc/rev, adjustable for varying torque requirements.
• Materials and Craftsmanship:
• Body: Cast iron or aluminum alloy for strength and corrosion resistance.
• Gears: Hardened steel gears for high wear resistance.
• Bearings: Needle bearings or precision rolling bearings to reduce friction and enhance mechanical efficiency.
------
3. Application Scenarios
• Construction Machinery: Drive systems for excavators, loaders, and road rollers (e.g., slewing mechanisms powered by hydraulic motors).
• Agricultural Machinery: Hydraulic lift systems or steering mechanisms in combine harvesters and tractors.
• Logistics Equipment: Hydraulic drives for forklifts and stackers.
• Industrial Sector: Hydraulic circuits in injection molding machines, die-casting machines, or as actuators in other hydraulic systems.

------
5. Selection and Usage Recommendations
• Pump Matching: Select displacement based on system flow requirements to ensure motor speed stays within optimal range (avoid low speeds causing pulsation).
• Pressure Setting: Set system pressure slightly above the motor’s rated pressure (e.g., 110% of rated value) for safety margins.
• Installation Position: Mount on the high-pressure side of the pump outlet, close to the pump to minimize pressure loss.
• Maintenance Interval: Regularly inspect seals for wear, gear engagement, and fluid cleanliness. Replace hydraulic oil every500 operating hoursor annually.
------
6. Common Faults and Troubleshooting
• Leakage: Check for aged or damaged seals; replace O-rings or composite seals.
• Pressure Instability: Clean valve spools and seats to remove contaminants; adjust spring preload.
• Excessive Noise: Verify hydraulic fluid viscosity or air entrapment; replace fluid and bleed the system.
• Failure to Start: Inspect for broken springs or stuck adjustment mechanisms; replace the valve body if necessary.
------
7. Industry Standards and Certifications
• International Standards: Compliant withISO 4408(hydraulic valve performance testing) andISO 10770-1(electro-hydraulic proportional valve standards).
• Safety Certifications: Certified byCE,UL, orCCS (China Classification Society)for export or specialized applications.
