Accumulator tube changing , Iran

HYDAC hydraulic accumulators are manufactured in three primary designs based on fluid-gas separation. The bladder type uses a flexible elastomeric bladder to separate the hydraulic oil and nitrogen gas. The diaphragm type employs a flexible membrane, while the piston type utilizes a mechanical piston. The accumulator shell is constructed from carbon steel, stainless steel, or aluminum. HYDAC bladder accumulators are available in capacities ranging from 0.5 to 450 liters. Piston and diaphragm types are typically offered up to 200 liters. These accumulators have nominal working pressures up to 330 bar for bladder models and 250 bar for diaphragm models. Some special models support pressures up to 1000 bar.

Charging HYDAC accumulators must be done exclusively with pure, dry nitrogen gas. The nitrogen purity should be at least 99.9%. For safe and precise charging, specialized charging kits like the HYDAC FPU-1-350/250 F2.5 model are used. This kit includes a pressure control regulator, a pressure gauge, a high-pressure hose, and standard fittings. The accumulators pre-charge pressure should be checked after any maintenance and at least once a week. If no pressure loss is detected, inspections can be extended to every four months or annually. The internal separating bladder is typically made from NBR elastomer compatible with mineral oil. IIR and FKM materials are also available for specific applications.You can order and buy Accumulator tube changing from Iran by contacting us through whatsaap and email.
