Primarily, accumulators are available in the bladder, diaphragm, piston and membrane models, each able to complete a dedicated task within the hydraulic system. Based on the application, they can be used to store and conserve system energy, dampening hydraulic fluid pulsation, and aiding in fluid pressure surge alleviation. The function is directly used to refuse the likelihood of loss of control of the flow of fluids within the hydraulic system.
Bladders are are hydropneumatic accumulators with a flexible bladder. It serves as a separate element between a compressible gas cushion and the operating fluid.
Diaphragm are are hydropneumatic accumulators with a flexible diaphragm with as a separation element between the compressible gas cushion and the operating fluid.
Use pistons as separating elements and can handle much higher gas compression ratios and flow rates.
Application A key customer required an electro-hydraulic control system for their remote control battery operated, full electric mining industry transmission service equipment. The solution needed to include hydraulic actuators, hydraulic valves as well as the electric motor and electronic control and radio remote control systems....
Application Frac tank trailers experienced mechanical failures with the manually-operated stabiliser legs. This resulted in prime mover wait time, and costly crane hire call-out to remote areas. Solution Designed and installed a complete hydraulic stabiliser legs system. The system comprises of hydraulic cylinders stabiliser leg...
Application The Flash Tank Rig is a hydraulically controlled actuator used to point a high-pressure water nozzle inside the ash tank so it is possible to clean scale out of the tanks during the shutdown period. Solution CFP has been working with RIO over the...
