Introduction
Hydronord's Constant Pressure System represents a significant innovation in hydraulic control, designed to maintain stable system pressure regardless of fluctuating flow demands or changing load conditions. This level of pressure regulation is essential for precise hydraulic operations across many industrial and mobile equipment applications.
System Concept
The core principle of a constant pressure system is to keep the hydraulic pump’s output pressure steady, even when flow rates or load demands vary. Unlike conventional systems where pressure dips under heavy load and spikes when loads lighten, a constant pressure system automatically adjusts to keep pressure uniform. This ensures consistent performance and protects sensitive equipment.
Working Mechanism
In mobile machinery—such as drilling rigs or hydraulic construction tools—a constant pressure system ensures smooth operation even as multiple hydraulic functions operate simultaneously. It prevents unexpected slowdowns, jerks, or performance drops that could hinder productivity or risk equipment integrity.
Maintenance and Tuning
Routine maintenance involves ensuring cleanliness and proper operation of the pressure compensation valve and pump electronics/debugging if equipped. For systems using electronic control, periodically verifying pressure sensor accuracy and valve response is recommended to maintain system stability.
Conclusion
Hydronord's Constant Pressure System elevates hydraulic control by delivering steady, reliable pressure under varying operational conditions. Its ability to adapt in real time with precision benefits both system performance and longevity. Whether used in industrial plants or mobile equipment, this system model offers a refined solution for demanding hydraulic environments.
Let me know if you'd like a breakdown of internal valve operation or real-world case scenarios where this system significantly improved hydraulic performance.

Working Mechanism
- Variable Displacement Pump
Hydronord systems typically use variable displacement pumps that modulate their internal flow-producing elements based on real-time pressure feedback.
- Pressure Compensation Valve
A hydraulic pressure compensation valve continuously senses the downstream pressure. When pressure drops (due to increased flow or load), the pump automatically increases its output. Conversely, the pump reduces output once set pressure is reached.
- Electronic or Hydraulic Controls
Control can be mechanical (valve-based) or enhanced with electronic regulation for more precise control, especially useful in systems that demand tight pressure tolerances.
- Precise pressure maintenance during tool cycles or changes in hydraulic demand
- Stable performance for sensitive equipment like actuators, hydraulic motors, and drilling tools
- Reduced energy loss, since pump only works to sustain target pressure rather than maximum displacement all the time
- Less system wear due to avoidance of repeated pressure surges and inefficient over-pressurization
