Bladder

Bladder AccumulatorsDescription Bladder Materials The bladder accumulator consists of a fluid section and a gas section, with the bladder acting as a gas-proof screen. The fluid around the bladder is connected with the hydraulic circuit, so that the bladder accumulator draws in fluid when the pressure increases thus compressing the gas. When the pressure drops, the compressed gas expands and forces the stored fluid into the circuit. Not all fluids are compatible with every elastomer at all temperatures. Therefore, HYDAC offers the following choice of elastomers: Construction HYDAC bladder accumulators consist of a welded or forged pressure vessel (shell), a bladder and ports for gas and fluid inlet. The gas and fluid sides are separated by the bladder. • • • • • • NBR (Standard Nitrile) LT-NBR (Low Temperature Nitrile) ECO (Epichlorohydrin) IIR (Butyl) FPM (Fluorelastomer) others (available upon request) To determine which material is appropriate... ALWAYS REFER TO FLUID MANUFACTURER’S RECOMMENDATION Corrosion Protection Valve Seal Cap Gas Valve Core Lock Nut Valve Protection Cap O-Ring Name Plate For use with certain aggressive or corrosive fluids, or in a corrosive environment, HYDAC offers protective coatings and corrosive resistant materials (i.e. stainless steel) for the accumulator parts that come in contact with the fluid, or are exposed to the hostile environment. Mounting Position HYDAC bladder accumulators can be installed vertically, at any angle, or horizontally depending upon the application. When installing vertically or at an angle, the fluid port must be at the bottom. On certain applications listed below, specific positions are preferable: Shell • Energy Storage: vertical Bladder • Pulsation Damping: any position from vertical to horizontal • Maintaining Constant Pressure: any position from vertical to horizontal • Volume Compensation: any position from vertical to horizontal System Mounting Poppet HYDAC bladder accumulators are designed to be screwed directly onto the system. We also recommend the use of our mounting components, which are detailed on page 33, to minimize risk of failure due to system vibrations. Applications Anti-extrusion Ring Seal Rings Spacer Ring Lock Nut Fluid Port Seal Ring Vent Screw Some common applications of bladder accumulators are: • Agricultural Machinery & Equipment • Forestry Equipment • Oil Field & Offshore • Machine Tools • Mining Machinery & Equipment • Mobile & Construction Equipment • Off- Road Equipment For specific examples of applications using bladder accumulators, please see page 45. 5 Accumulator Catalog 1) D = NPT (ANSI B1.5 gallons 5 gallons 10 gallons 11 gallons 15 gallons Line Connection A F = Threaded = Flanged Gas Port 1 = Standard model.Bladder Accumulators Model Code SB 330 __ .5 gallons 2.6000 psi (Code 62) Model Codes containing red selections are non-standard items – Contact HYDAC for information and availability Not all combinations are available 1-877-GO HYDAC Accumulator Catalog 6 .
