description

It adopts proven bladder structure with high‑strength forged steel shell and oil‑resistant rubber bladder to separate nitrogen and hydraulic oil. The built‑in anti‑ejection valve protects the bladder. Every unit passes strict pressure, air tightness and leakage test. The coated outer shell resists corrosion. Replace it once pressure holding fails, oil leakage occurs or the bladder ruptures. Fully depressurize before any disassembly.

product parameters

Part No.: 804026605
Name: Hydraulic Accumulator
Type: Bladder accumulator
Shell Material: High‑strength alloy steel
Medium: Hydraulic oil + pre‑charged nitrogen
Process: Forging, machining, welding, NDT, pressure test, anti‑corrosion coating
Applicable Model: XCMG RP705 medium crawler asphalt paver

Applicable Scenarios

It is installed near the hydraulic pump station, pilot circuit or hopper control circuit of RP705 paver. Replace it when pressure holding capacity is lost, bladder fails or shell leaks. It is widely used on highway and municipal paving sites and machinery overhaul workshops.

advantage

- Genuine accumulator with matched volume, working pressure and port size for RP705
- Forged high‑strength shell with excellent fatigue resistance under cyclic hydraulic impact
- Premium oil‑resistant bladder with low nitrogen leakage rate
- Built‑in anti‑blowout valve to avoid bladder blockage in pipelines
- Protective coating against hot asphalt, mud and splash
- Factory pressure tested to eliminate porosity and leakage

FAQ

Q: Are there requirements for pre‑charge nitrogen pressure?
A: Yes. Follow the official XCMG service manual. Improper pre‑charge pressure will degrade its buffer and holding performance.

Q: What if the pressure drops rapidly?
A: First inspect seals and charging valve for external leakage. If no external leak exists, the internal bladder is broken and the whole accumulator must be replaced.

Q: Can the bladder be repaired on site?
A: On‑site disassembly and repair are not recommended. Once the bladder fails, replace the complete assembly.

Q: What is the key safety rule for removal?
A: Shut down the machine and fully depressurize the circuit before disassembly. Never work on a pressurized accumulator.
