MDP Hydraulics
This high-pressure hydraulic power station is a highly integrated and modular core power unit of the hydraulic system, specifically designed for industrial applications that require stable and reliable high-pressure hydraulic power. It organically integrates high-performance motors, high-pressure hydraulic pumps, multi-functional integrated valve blocks and intelligent control systems, replacing the complex pipeline connections of traditional decentralized hydraulic systems, and providing precise and controllable power sources for various hydraulic actuators (such as cylinders and hydraulic motors).
The core of this power station lies in its integrated valve block design, which serves as the "nerve center" of the hydraulic system. It integrates multiple functional valves, such as relief valves, directional control valves, and check valves, through precisely machined internal channels into a single robust valve body. This design not only significantly reduces external leakage points and enhances system reliability but also makes the equipment structure extremely compact, making it particularly suitable for installation environments with limited space.
It adopts an integrated design, integrating the pump, valve, motor, oil tank and control components. Compared with traditional split hydraulic stations, its volume can be reduced by 30% to 50%, and it is flexible and convenient to install.
Valve body material: High-strength aluminum alloy or ductile iron is used, which is resistant to high pressure and corrosion, ensuring long-term stability under harsh working conditions.
Flow channel process: The internal oil passage channels are precisely machined by a five-axis linkage machining center, with a surface roughness of Ra ≤ 0.8 μm. This effectively reduces pressure loss, minimizes turbulence and cavitation, and enhances energy efficiency.
Function integration: According to customer requirements, it can integrate relief valves (system safety pressure limit), directional control valves (control the direction of cylinder movement), check valves (pressure holding and anti-backflow), pressure reducing valves, throttle valves, etc., to achieve complex hydraulic logic control.
Leakage control: Significantly reduces external pipelines and joints, fundamentally lowering the risk of leakage. High-performance sealing technology is used at critical sealing points to ensure long-term sealing at pressures above 200 bar.
Maintenance convenience: Adopting a layered or modular structure design, individual valves can be replaced independently without disassembling the entire valve block or system, significantly reducing maintenance costs and downtime.
Thermal management: The valve block can be embedded in the cooling circuit, and the oil tank has excellent heat dissipation capacity. Optional air-cooled or water-cooled coolers can be selected to effectively control the oil temperature and ensure the long-term stable operation of the system.
Filter protection: Equipped with a high-precision return oil filter (such as a 25μm filtration accuracy) as standard, and featuring a contamination indicator, it effectively protects pumps, valves and other precision components, extending the system's lifespan.
Flexible control: Supports manual and electric solenoid valve control, and can be integrated with PLC interfaces, pressure sensors, flow meters, etc., reserving interfaces for intelligent monitoring and remote control.
