SB81 Accumulator Replacement Membrane

Product Description

OEM grade HNBR SB81 hydraulic breaker rubber diaphragm for Soosan SB81 series hammer, oil-proof high temp resistant accumulator membrane, factory wholesale spare parts with.

Advanced Production Technology

  1.  Raw rubber incoming inspection: ingredient test, hardness & tensile property detection, reject inferior recycled rubber stock.
  2.  Closed mixing refining: multi-stage rubber mixing to disperse anti-aging, wear-resistant auxiliary evenly inside rubber matrix.
  3.  High-pressure hot mold one-step seamless compression vulcanization under fixed temperature & constant pressure.
  4.  Post-vulcanization secondary tempering standing to release internal vulcanization stress of rubber.
  5.  Appearance full inspection: surface pinhole, crack, deformation screening one by one.
  6.  Random sampling: air tightness inflation test & alternating expansion fatigue durability test.
  7.  Qualified finished product surface dust cleaning, individual PE bag sealing packing.

Working Principle

  1.  Return stroke: High-pressure hydraulic oil flows into breaker lower cavity, piston moves upward, hydraulic oil enters accumulator   oil chamber to squeeze diaphragm inward, inner nitrogen of diaphragm is compressed, hydraulic energy converts into nitrogen   compression potential energy for storage.
  2.  Oil circuit reverses when piston reaches top dead center, high-pressure oil switches into upper piston cavity.
  3.  Power stroke: Compressed high-pressure nitrogen inside diaphragm expands outward instantly, push diaphragm to extrude   stored hydraulic oil back into hydraulic circuit, supplement instantaneous high flow to drive piston fast downward striking chisel.
  4.  Single striking finished, hydraulic oil pushes diaphragm to compress nitrogen again, repeat reciprocating energy storage &   release cycle continuously.
  5.  The diaphragm always separates nitrogen gas and hydraulic oil completely to avoid gas-liquid mixing and system pressure   failure.

FAQ

Q1: What causes original diaphragm frequent nitrogen leakage?

A1: Rubber aging, inner crack or pinhole damage caused by over-high pre-charged nitrogen pressure.

 

Q2: What is the raw material of this SB81 membrane?

A2: High-performance imported HNBR hydrogenated nitrile rubber with anti-aging formula.

 

Q3: Can I buy one piece sample first before bulk purchase?

A3: Yes, single sample available, bulk order gets preferential tiered pricing.
