根据多年升降货梯http://www.jntr168.com/液压管路系统研究和生产积累的经验，导致液压胶管总成故障原因有液压胶管总成在扣压接头时，扣压力度过大，胶管内胶层埙伤，造成漏油。升降货梯液压胶管总成在扣压接头时，扣压力度不够，造成渗油，漏油和拔脱。在反复的脉冲压力作用下，外套反弹，扣压力度减小，造成渗油，漏油和拔脱。升降货梯接头加工精度不达标，造成接口处漏油，渗油。
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.
       
因此大家需要对升降货梯http://www.jntr168.com/液压管路对接头内芯和外套在机加工过程中，要有严格的尺寸控制，加工标准要控制在0.05mm以内。升降货梯选用优良性能的扣管机，扣压力度尺寸控制在0.1mm以内。升降货梯接头连接部位建议使用车削中心加工，因为它有良好的稳定性和加工精度。
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.
