olaer accumulator , Iran

Oilair hydraulic accumulators comply with PED and CE standards. Their volumetric capacity ranges from 0.15 to 150 liters. The maximum allowable working pressure reaches 350 bar. The standard operating temperature spans from -50 to +120 degrees Celsius. These units are designed in diaphragm and bladder types. The main body is constructed from carbon or stainless steel. Nitrogen gas serves as the compressible fluid. Standard connections include metric and inch threads. The pre-charge to working pressure ratio is typically 0.9. Their primary purpose is absorbing shock and pressure pulsations.

The main cylinder of these accumulators uses high-quality steel. This cylinder undergoes precise heat treatment. The internal shell is protected by epoxy or zinc coatings. Diaphragm models feature EPDM or NBR rubber diaphragms. This diaphragm is produced via injection molding. The gas valve is an integrated safety valve type. Critical seals are made from Viton or fluorocarbon. All units undergo hydrostatic pressure testing before shipment. These tests reach up to 1.5 times the working pressure. Their design allows for installation in any orientation.
