根據多年升降貨梯http://www.it616.com.cn/液壓管路系統研究和生產積累的經驗，導致液壓膠管總成故障原因有液壓膠管總成在扣壓接頭時，扣壓力度過大，膠管內膠層塤傷，造成漏油。升降貨梯液壓膠管總成在扣壓接頭時，扣壓力度不夠，造成滲油，漏油和拔脫。在反復的脈沖壓力作用下，外套反彈，扣壓力度減小，造成滲油，漏油和拔脫。升降貨梯接頭加工精度不達標，造成接口處漏油，滲油。
Based on years of experience in the freight elevator lift hydraulic piping systems research and production accumulated causes hydraulic hose assembly hydraulic hose assembly failures during withhold joints, buckle pressure through the large, inner hose layer Xun injury, causing oil spills. Cargo lifter hydraulic hose assembly joints when withholding, withholding enough, causing oil leakage, oil spills and pull off. Under repeated pulse pressure, jacket rebound withhold intensity decreases, causing oil leakage, oil spills and pull off. Cargo lifter fitting precision is not up to the oil spill caused by the interface, oil leakage.
因此大家需要對升降貨梯http://www.it616.com.cn/液壓管路對接頭內芯和外套在機加工過程中，要有嚴格的尺寸控制，加工標準要控制在0.05mm以內。升降貨梯選用優良性能的扣管機，扣壓力度尺寸控制在0.1mm以內。升降貨梯接頭連接部位建議使用車削中心加工，因為它有良好的穩定性和加工精度。
So we need to lift freight elevator hydraulic pipe fittings for the inner core and jacket in the machining process, there must be strict dimensional control, and processing standards should be controlled within 0.05mm. Cargo lifter selection button machine with excellent performance, withholding size control efforts within 0.1mm. Cargo lifter fitting joints are recommended turning machining center, because it has good stability and precision.
