LEHIY Industrial has stocked a large quantity of HYDAC SB330 bladder accumulators and bladder accessories in response to requests from steel mills and cement plants. The following is a list of the HYDAC accumulator and HYDAC bladder models currently in stock.
The HYDAC accumulator models in stock are: SB330-1A1/112A9-330A, SB330-4A1/112A9-330A, SB330-10A1/112A9-330A, SB330-20A1/112A9-330A, and SB330-50A1/112A9-330A. The HYDAC bladder models are: 2.5L, 4L, 10L, 13L, 20L, 32L, and 50L.
In hydraulic systems, HYDAC SB330 series accumulators are essential hydraulic components, widely used in hydraulic power units.
Their primary function is energy storage, hence the high demand. Based on their application, HYDAC accumulators can be broadly categorized into four types: energy storage, pulsation absorption, constant pressure, and capacity compensation.
HYDAC Accumulator Product Introduction: The standard HYDAC bladder accumulator series model SB330 consists of a pressure vessel, a HYDAC bladder with a valve, and an oil valve. The pressure vessel is seamless and made of high-quality steel.
HYDAC Accumulator Installation: HYDAC accumulators can be installed vertically, horizontally, or at an angle.
When installed vertically or at an angle, the oil valve must be located below.
For specific applications, the following recommended locations should be prioritized: For energy storage, vertical installation is recommended; for pulsation absorption, installation in any position from horizontal to vertical is recommended; for maintaining constant pressure, installation in any position from horizontal to vertical is recommended; for capacity compensation, vertical installation is.
recommended.
If the HYDAC accumulator is installed horizontally or at an angle, the effective capacity and the maximum permissible flow rate of the oil will be reduced. Hydac accumulator bladder SB330-24A1/114A9-330A, SB330-24A1/114A9-330A accumulator bladder 24L*7/8-14UNF/VG5 IIR44/P460. Hydac bladders and diaphragms.
Model code marking example: US standard 15GAL, nitrile rubber, 7/8UNF valve stem bladder. Marked as: B-15G-7/8UNF-1-A. For a 15GAL accumulator, Standard Buna N Aromatic Resistant bladder, the thread of the gas stem is 7/8 UNF.
The type of the bladder is B-15G-7/8 UNF-1-A.
- Hydac bladder models and dimensions. (China national standard for rubber bladder dimensions)
- Standard bladder compounds (the bladder can be supplied with the following choices of compounds to render it compatible with the system fluid). HYDAC bladder compound numbers: -1=Standard Buna N Aromatic Resistant -3=Buna N High Temperature -4=Low Temperature -8=Ethylene Propylene -6=Butyl -27=Polychloroprene -28=Fluorocarbon (Viton) HYDAC accumulators and bladders from Germany are available.* LEHIY Industrial offers advantageous supply of HYDAC piston accumulators. Functions: 1 1) Eliminating pulsation and reducing noise: For hydraulic systems using piston pumps with a small number of pistons, the periodic change in pump flow causes system vibration. 2) Storing energy: ① As an auxiliary power source, reducing installed capacity;
- ② Compensating for leakage;
- ③ Compensating for thermal expansion;
- ④ As an emergency power source;
- ⑤ Constructing a constant pressure oil source. 3) Recovering energy: Energy recovery can improve energy utilization and is an important way to save energy. Hydac piston accumulators can temporarily store energy, so they can be used to recover various functional and positional potential energy. The main research in this area includes: ① Recovering vehicle braking energy;
- ② Recovering the potential energy of the boom mechanism of I-type machinery;
- ③ Recovering the braking energy of the turntable of hydraulic excavators;
- ④ Recovering the gravitational potential energy of oil well workover rigs and drilling pipes falling;
- ⑤ Recovering the gravitational potential energy of elevators descending. 4) Absorbing hydraulic shock: Sudden switching of directional valves and sudden stopping of actuator movement will generate pressure shocks in the hydraulic system, causing the system pressure to rise rapidly in a short time, damaging instrument components and sealing devices, and generating vibration and noise. The SB330 HYDAC The accumulator offers the following advantages: high discharge rate, no pressure difference between the fluid and gas sides, compact design, low maintenance, and high charge/discharge frequency. The HYDAC accumulator is a hydraulic-pneumatic accumulator with a flexible gas core as a separation element between the compressible air cushion and the working fluid.
Plain language sourcing guide for HYDAC accumulators and bladders from Germany are available*
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
