机车锅炉安全阀弹簧及风泵调压器压力头弹簧是调整压力以保证作用灵敏的主要零件。弹簧偏歪不正会影响组装中心不一致,造成阀口关闭不严及感度不灵敏,因而检修工人对弹簧的检查特别注意,检查弹簧偏歪的方法,是将弹簧立在平台上,用直角尺贴靠,检查弹簧的上下平面是否与弹簧的中心母线垂直,如发现不垂直和偏歪倾斜过限者(一般掌握的限度是0.5 Locomotive boiler safety valve spring and wind pump pressure regulator pressure head spring is to adjust the pressure to ensure that the role of sensitive parts. Unbalanced spring will affect the assembly center inconsistencies, resulting in lax valve closure and sensitivity insensitivity, so overhaul workers pay special attention to the inspection of the spring, check the spring bias is the spring stand on the platform, with a rectangular foot stickers By, check the spring up and down the plane is perpendicular to the center of the spring bus bar, if found to be not vertical and skew tilt over the limit (the general control of the limit is 0.5
