液压升降平台在寒冷天气下如何维护？升降平台厂家提醒，伴随着冬天的来临，天气越来越冷，寒冷的天气也带来了冰冷的雨水。升降平台多数工作在室外，那么应该如何进行维护呢？升降平台厂家这为您提供维护建议，更具体的维护请来电咨询。为了更好的使用升降平台，我们在此为广大用户提供低温环境对液压升降平台造成影响的三个注意事项。Hydraulic lift platform in the cold weather how to maintain? Lifting platform manufacturers to remind, with the advent of winter, the weather is getting colder and colder, cold weather has brought the cold rain. Most of the work in the outdoor platform, then how to maintain it? Elevating platform manufacturers to provide you with suggestions and more specific maintenance, please call advisory. In order to better use the lifting platform, we provide the majority of users in the low temperature environment on the hydraulic lifting platform of the three points of attention.
1.从原材料来讲，低温环境对钢材的影响。我们在生产液压升降平台时选用的材料，在低温下主要受力构件不但要满足强度的要求，还必须满足冲击韧性的要求。低温受力构件的焊接结构形式对焊接热应力、应力集中等影响很大，因此液压升降平台在低温下应选择更合适的结构形式。From raw materials, the impact of low temperature environment on steel. In the production of hydraulic lifting platform, we choose the material, at low temperature, the main stress components not only to meet the requirements of strength, but also to meet the requirements of impact toughness. The welding structure of low temperature stress component has great influence on welding thermal stress and stress concentration, so the hydraulic lifting platform should choose more suitable structure form at low temperature.
2.升降平台厂家提醒，低温环境对液压升降机液压油、润滑油脂、柴油的影响。液压升降平台支腿收放系统和起重作业的卷扬变幅、回转和伸缩等动作均由液压油作为工作介质传递动力。液压油的粘度至关重要，粘度过高，系统内部摩擦阻力增大，压力损失增多，油温上升过快，操作时动作滞后；粘度过低，泵的容积效率低，润滑性能差，零部件间运动摩擦阻力增大。液压油的粘度随工作温度而变化，因此选择低温用液压油时应特别注意。Lifting platform manufacturers to remind, low temperature environment on the hydraulic lift hydraulic oil, lubricating oil, diesel oil. Hydraulic lifting platform leg retraction system and lifting hoisting luffing and slewing and stretching action by the hydraulic oil as the working medium to transfer power. Critical hydraulic oil viscosity is too high, the system of internal friction resistance increases, the pressure loss increased, the temperature rises too fast, action lag; the viscosity is too low, the volumetric efficiency of the pump is low, poor lubrication, the friction resistance increases movement between parts. The viscosity of hydraulic oil varies with the working temperature, so it should pay special attention to the selection of hydraulic oil at low temperature.
3.低温环境对液压升降平台齿轮油的影响。润滑油，变速箱、分动箱、驱动桥、卷扬机构、回转机构在低温下运行时，液压升降机的润滑油应选粘度指数高、凝点低、润滑性好的齿轮油，否则会导致传动效率明显降低，传动零件磨损增加，变速箱和分动箱操作沉重，换档困难。Influence of low temperature environment on gear oil of hydraulic lifting platform. Lubricating oil, transmission, transfer case, driving bridge, hoisting mechanism, slewing mechanism under low temperature, lubricating oil viscosity index should be hydraulic lift high, low pour point, good lubrication oil, otherwise it will lead to significantly reduce the transmission efficiency, transmission parts wear, transmission and transfer case operation is heavy, difficult shift.
液压升降平台在寒冷天气下如何维护？升降平台厂家认为这是入冬以来客户最为关心的问题。液压升降平台是可以在室外运行使用的，理论的使用温度为-20℃-60℃。但是我们也要根据实际使用情况进行正常维护，以保证日常液压升降平台的工作。Hydraulic lift platform in the cold weather how to maintain? The lifting platform manufacturers think it is winter customer concern. Hydraulic lifting platform can be used in outdoor operation, the theory of the use of temperature -60. But we also need to be based on the actual use of the normal maintenance, to ensure that the daily work of the hydraulic lifting platform.
