All Pressure vessel inspections shall be carried out by a competent person, such as a Boiler inspector or Company that specializes in Pressure vessel inspections.
A hydraulic accumulator is used for one of two purposes: either to add volume to the system at a very fast rate or to absorb shock. Which function it will perform depends upon its pre-charge. If the accumulator is to be used to add volume to the system, its pre-charge must be somewhat below the maximum system pressure so oil can enter it.
Hydraulic accumulators are pressure vessels and as such require statutory regulation. All Pressure vessel inspections shall be carried out by a competent person, such as a Boiler inspector or Company that specializes in Pressure vessel inspections. 1. Design Registration D shall be design registered with WorkSafe WA.
A myriad of regulations apply to hydraulic accumulators, depending on where and how they are used. • Two basic codes, from the U. S. and European Union, govern the design of most accumulators. • Many countries amend the basic codes with additional testing and certification requirements.
Specifications for hydraulic accumulators include Typically, devices are sized according to their effective or actual gas volume when all of the hydraulic fluid is discharged. The available volume of fluid depends upon the available volume of compressed gas, an amount known as the working volume.
All pressure vessels manufactured to these standards are considered to have a finite service life depending on the number of pressure cycles experienced during normal operation. The typical design life for a hydraulic accumulator is 12 years. In many jurisdictions, periodic inspection and recertification is required.
