6 Frequently Asked Questions about “Accumulator Piston Seal Installation”
How do you seal a cyclinder accumulator?
On large end caps, an extension rod can be used. Push the piston out of the accumulator in the direction of the fluid side using a suitable plastic/wooden rod and rubber mallet--taking care not to dent cyclinder threads. Follow the detailed instructions below on how to install seals onto a conventional piston.
How should a piston accumulator be stored?
allow equal pressure on both sides of the seal.The pre-charge should be bled off and the system fluid in the accumulator must be drained prior to inst llation of the piston accumulator on the system.It is also recommended that the units be stored in a vertical position to prevent the seals from developing a set (flat spo
How do you install a piston accumulator?
lean the accumulator with dry, non-fiber cloths.Remove the pro ective cap from the oil port of the accumulator. Connect and prop rly tighten the hydraulic lines to the oil port. The PA and installed.Piston Accumulator or Ga
How do you remove a piston accumulator from a hydraulic system?
Isolate the fully charged piston accumulator from the hydraulic system by closing the shut off valve A. Slowly discharge the accumulator on the fluid side via drain valve E. The pressure gauge must be constantly monitored during this process. A slow, steady pressure drop is displayed.
How do I repair a piston accumulator?
When repairing a piston accumulator, it is critical to use the appropriate tools to avoid seal damage. There are two tools required: a tapered shroud that protects the seals from the threaded portion of the shell, and provides even seal compression and piston alignment when inserting the piston into the shell.
How to handle a piston accumulator?
When handling the piston accumulator, care must be exercised in order to avoid damaging surfaces, whether they are painted or metallic, on the housing or end-caps. In addition, the gas valve, gas valve cover, pressure fuse, or other mounted accessories must be also kept free of any damage.
