Negative-pressure tube
Category:
Made from aluminum alloy and featuring a hard-anodized surface on the negative-pressure tube, this design ensures a smooth, wear-resistant inner and outer surface, effectively preventing fiber buildup. The use of a dual-spindle configuration with stainless-steel wear plates maximizes coverage, minimizing air leakage and deformation during disassembly, while also facilitating seamless product-changeovers among ring spinning, siro spinning, compact spinning, and compact-siro spinning processes. To date, Wanbao’s negative-pressure tubes have evolved through seven generations; the company’s independently developed torsion-spring tension mechanism has been granted a patent. On low- and medium-count spinning frames, the cleaning cycle can exceed 20 days, significantly reducing labor intensity, lowering staffing costs, and boosting production. At the same time, wear on the grid rings is substantially reduced, extending their service life by more than 20%.
