Wave-compensated three-chamber cylinder

Unlike conventional double‑acting cylinders that have only two chambers—the rodless chamber and the rod side—three‑chamber cylinders, through a hollow piston rod, an internal core column, or a composite piston design, incorporate an additional third chamber (commonly the piston rod’s internal cavity, an auxiliary balance chamber, or an acceleration chamber). These three chambers can be supplied with fluid independently or in combination, enabling sophisticated motion control.

Synchronous servo relay

Traditional flow‑synchronization systems, such as those used for penstock gate valves in hydropower stations, typically require six sets of synchronizing servomotors. These systems rely on either synchronous motors or mechanical linkages—often employing a mechanical lead‑screw drive to achieve synchronization—but they suffer from issues like reduced accuracy due to wear and tear, as well as potential lead‑screw breakage caused by air pockets in the mechanical transmission. In contrast, the SCHWERLL hydraulic servo digital control system achieves digital synchronization via a hydraulic servo control loop and employs a multi‑channel hard‑sync cylinder design driven by piston accumulators equipped with energy‑monitoring capabilities. This enables emergency shutdown functionality under fault conditions, ensuring long‑term repeatability of synchronization accuracy and high‑precision hard synchronization even during complete power loss. Meeting the stringent requirements of applications such as penstock gate valves—where high precision, excellent repeatability, and reliable emergency synchronization under total power‑outage conditions are critical—the SCHWERLL system represents the optimal synchronization solution.

Die-casting cylinder

When aluminum alloys, aluminum–magnesium alloys, magnesium alloys, and other metals are formed by die‑casting, it is necessary to account for the forming process, including rapid injection control (for shaping) and pressure‑holding control (for fine solidification). The forming process typically employs a piston‑accumulator system as the power source and is driven by a hydraulic servo‑controlled rapid‑forming system. As the actuating element, the hydraulic cylinder must achieve a piston‑rod speed of 8–12 m/s, necessitating the use of high‑speed servo‑driven injection cylinders to complete the injection‑forming operation. Key characteristics of these injection cylinders include:
