5. FAQ
Q: What are the natural color and surface features of each part without added pigment or surface treatment?
A: Heat-resistant NBR parts are deep black with a soft matte texture and strong resilience. High-elasticity PU seals present light amber and have a dense, smooth surface. Graphite-modified PTFE rings are dark gray with uniform fine texture brought by graphite filler. Twisted fabric guide rings are dark tan brown, with distinct spiral woven lines on the surface.
Q: What are the prominent advantages of high-elasticity PU in scraper hydraulic cylinders?
A: As the core dynamic sealing part, this PU material retains excellent elasticity even after long-time repeated stretching and compression. When the scraper completes lifting, hoisting and dumping actions continuously, it closely fits moving components to lock high-pressure hydraulic oil inside the cylinder. It can resist wear and deformation under long-cycle operation and heavy load, keeping stable sealing performance all the time.
Q: What role does graphite-modified PTFE play when matched with main seals?
A: Graphite filler endows PTFE with lower friction coefficient and better heat dissipation performance. It can fill tiny gaps in piston installation grooves perfectly. When the cylinder bears instant overload and creates pressure surges during material dumping, it shares pressure effectively and prevents the sealing lip from being extruded and damaged, while reducing running resistance of the whole cylinder.
Q: What makes heat-resistant NBR different from ordinary rubber materials?
A: This upgraded NBR is optimized for high-temperature working environments. Besides basic oil resistance and anti-aging performance, it will not soften or lose tightness when working under sustained high temperature. It also resists oxidation caused by long-term exposure to flowing air and hydraulic oil, suitable for scrapers running continuously for whole shifts.
Q: Where are the heat-resistant NBR seals mainly installed on the hydraulic cylinder?
A: These rubber components are mainly mounted on static connection positions, including cylinder end cover joints, flange faces and threaded ports of auxiliary hydraulic pipelines. These positions are close to heat sources and stay immersed in hydraulic oil for a long time, which can fully exert the high-temperature resistance and static sealing performance of NBR.
Q: How does the twisted fabric phenolic guide ring work during piston movement?
A: This specially woven guide ring can absorb lateral force generated by unbalanced load during operation. It corrects slight radial deviation of the piston, guides it to move along the central track steadily, and minimizes direct friction between metal parts. This design slows down component wear and ensures the cylinder runs smoothly and quietly.
