Product Overview: Pressure Boost Control

The Pressure Boost Control system enhances operational efficiency by automatically adjusting the hydraulic pressure based on load conditions. This sophisticated mechanism ensures optimal performance, especially during high-demand tasks.

Key Features

• Dynamic Boost Control: Automatically increases main relief valve pressure from 34.3 MPa to 36.8 MPa when high-load conditions are detected.
• Mode-Specific Control: In SP or H work modes, the boost activates for up to 8 seconds. In contrast, the A work mode allows for continuous pressure boosting without time restrictions.
• Sensitive Load Detection: The system is adept at monitoring engine load ratios and pump pressures to activate boost when necessary.
• Operation-Triggered Boost Suspension: Automatically halts boost when certain conditions, such as operation stops, are met.
• Travel and Breaker Restrictions: Prohibits boosting when travel sensor is on or during breaker use, ensuring safety and equipment integrity.

Benefits

• Enhanced Performance: Ensures machinery operates efficiently under varying load conditions, maximizing productivity.
• Energy Efficiency: Adjusts pressure dynamically to prevent unnecessary energy consumption.
• Increased Equipment Lifespan: System intelligently manages pressure to reduce wear and tear on hydraulic components.

Usage Recommendations

• Optimal Work Modes: Utilize SP or H modes for temporary boosts and A mode for continuous boosting when necessary.
• Monitor Load Conditions: Ensure engine and pump pressures are within operational parameters for maximum system effectiveness.
• Avoid Prohibited Conditions: Disable boost during travel or breaker operations to maintain system safety.
