冷却提升机是一种旧砂提升设备,同时具有冷却旧砂(一般能使旧砂温度降低7～10℃和去除旧砂中部分粉尘的作用。目前我国的冷却提升机有两种类型:其一是在丹麦进口的垂直分型无箱射压造型线上配套使用的设备,现在已有完全仿造的产品;其二是在原设备的基础上经过改进的产品。后者主要是改进了旧砂冷却系统,将背部吸尘风管作了较大变动,克服了原机冷空气“短路”的现象。我厂于1982年安装了一台S87系列的冷却提升机,该机属于前一种类型。在使用中我们发现,不仅该机的冷却系统不合理,而且存在着皮带悬垂的问题。据了解,有几家使用此种
Cooling hoist is an old sand lifting equipment, and has the effect of cooling the old sand (usually make the temperature of the old sand lower 7 ~ 10 ℃ and remove some of the old sand.) At present, there are two types of cooling hoist: its First, the equipment used in the vertical sub-type boxless injection molding line imported from Denmark now has completely imitated products; the second is the improved product based on the original equipment, the latter mainly improves the quality of old sand Cooling system, the back of the suction duct made a larger change to overcome the original machine cold air “short circuit.” I plant in 1982 installed a S87 series of cooling hoist, the machine belongs to the former type In use, we found that not only the machine’s cooling system is unreasonable, and there is the problem of belt drape It is understood that several use of this
