Specialized balancing cylinder products


Closed-type tank buffer

In a closed-loop hydraulic system, the return oil tank, being sealed and integrated into the system circuit, experiences pressure fluctuations due to entrained air. Therefore, the tank must be equipped with a buffer to ensure stable operation of the entire closed system.

High-Frequency-Response Servo Valve Damper

When the system requires stable flow regulation for a liquid—such as cooling water—a stainless steel cooling‑water pressure regulator must be installed in the piping. This regulator stabilizes the system’s water pressure, thereby delivering cooling water at a consistent pressure to the load side.

Hydraulic balance cylinder

The application of hydraulic balance cylinders in industrial robots and lifting platforms. The role of the closed system is to counteract the axial load torque, because the axial drive is not statically overloaded, and it can provide the maximum acceleration axial torque. The function of the enclosed gas in the diaphragm accumulator is equivalent to a mechanical spring.

Underwater piston or bladder-type hydraulic buffer

SCHWERLL underwater hydraulic accumulators (with separate chambers for the seawater side and the hydraulic oil side) are available in configurations where one end is connected to seawater and the other to hydraulic oil. They may feature either a floating‑piston design (with an isolating piston) or a bladder‑type design (diaphragm‑type). In both cases, the chamber is divided into two independent compartments by a wear‑resistant isolating piston or a flexible bladder.

Stainless Steel Pressure Compensator

At the outlet of the cooling water circulation system’s pump and other locations, pressure balancing and compensation are required. Canned‑type or diaphragm‑type pressure‑compensation devices are typically employed; due to the nature of the process fluid, these units are usually fabricated from stainless steel and other suitable materials, and are custom‑designed to match the system’s pressure and flow characteristics.

Closed-Loop Pressurized Fuel Tank

In closed-loop systems, the use of conventional hydraulic reservoirs is constrained by system dynamics and installation space; therefore, pressurized reservoirs must be employed to form a closed hydraulic circuit, thereby reducing the overall equipment footprint.
