    在中国北方,进入冬天的时候,温度突然降低,格外是东北、内蒙古等地的温度更是降到零下30多度,在这样的恶劣的环境下,,无疑是对液压升降机正常工作的一种严峻考验。有许多液压升降机装置在上述区域,入冬以后开始无法正常使用了,这是什么缘由形成的呢?当然,有人说式冰天雪地的,的确如此,不过不仅仅如此,下面咱们就深度剖析一下是什么缘由行程液压升降机在冬天不能正常工作的。

    有许多人认为,进入冬天以后,因为冰冷的气候形成了液压升降机的液压油的封冻,液压油不能正常回流油箱,形成缓慢降低,或许不降低。可是这不是主要缘由,其实许多专业的工作人员不知道液压油也是分夏天与冬天运用不一样品种的要求。通常在秋冬低温下,运用夏日液压油会呈现一系列的问题,更有可能会呈现结冰、冻住的情况、其实,冬天也应该运用焊防冻剂的液压油,进入冬天后,必须要记住运用冬天含有防冻剂的液压油,因为防冻剂在一定程度上保护了液压油不被外接的冰冷空气所搅扰,这种液压油适合低温下工作,也格外适合在广阔的北方区域运用。

    因为液压升降机的钢材在低温下,会有明显的热胀冷缩的特性,一般特种设备在规划的时候都会将钢材这种特性考虑进去,可是毕竟在不一样环境下体现不一样,在极度低温的条件下,钢材也会呈现一些不太安稳的体现,如:硬度添加,韧度降低等变得沉重,再加上货物起升,速度自然变慢。这个时候咱们就需要多留意保护液压升降平台设备在运用前,多空载起升、降低来回几次,在关键部位保持润滑,避免呈现干磨的现象发生。

In north China, the temperature drops suddenly in winter, especially in northeast China and Inner Mongolia, where the temperature drops to more than 30 degrees below zero. In such a harsh environment, it is undoubtedly a severe test for the normal operation of hydraulic lift. There are many hydraulic lift devices in the above area, after winter began to be unable to use normally, what reason is this formed? Of course, some people say it’s icy, but it’s more than that. Here’s an in-depth look at what’s wrong with a trip hydraulic elevator that doesn’t work in the winter.
Many people believe that, after entering the winter, because of the cold weather formed the hydraulic oil seal of the hydraulic lift, the hydraulic oil could not return to the oil tank normally, forming a slow decline, perhaps not lower. But this is not the main reason, in fact, many professional staff did not know that hydraulic oil is divided into summer and winter use of different varieties of requirements. Often in autumn and winter low temperature, using hydraulic oil in summer can present a series of problems, are more likely to be ice, frozen, in fact, winter also should use welding antifreeze hydraulic oil, after entering the winter, must remember use hydraulic oil containing antifreeze in winter, because antifreeze protection to a certain extent the hydraulic oil would not be disturbed by the external cold air, the hydraulic oil is suitable for work under low temperature, is especially suitable for use in the northern regions of the vast.
Because of hydraulic lift steel at low temperatures, have obvious characteristics of the heat bilges cold shrink, special equipment at the time of planning will be mild steel this feature into consideration, but after all reflect different under the different environment, under the condition of extremely low temperature, the embodiment of the steel will also show some not too safe, such as: add hardness, toughness decrease becomes heavy, such as plus cargo lifting, natural slow speed. At this time, we need to pay more attention to protect the equipment of hydraulic lifting platform. Before the use of the equipment, it should lift up and lower back and forth several times, keep lubrication in key parts, and avoid the occurrence of dry grinding.
