S114型辗轮式混砂机是青岛铸造机械厂五十年代开始生产的一种混砂设备。该产品具有结构紧凑、使用可靠、操作维修方便、售价低等优点,社会需求量很大,深受乡镇企业欢迎。但该机存在效率低、能耗大等缺点,被列为淘汰产品。由于该机社会拥有量较大,如全部更新,费用较高。为了提高它的混砂效率,降低能耗,我们自1987年开始拟定了改型技术方案,并对方案进行了技术经济可行性论证。改型的主导思想是:改型后的产品与原来S114
S114-type rolling wheel mixer is a kind of sand mixing equipment that Qingdao Foundry Machinery Factory began to produce in the 1950s. The product has the advantages of compact structure, reliable operation, convenient operation and maintenance, low price and so on. It is greatly welcomed by township enterprises. However, this machine has the disadvantages of low efficiency, large energy consumption and the like, and is listed as a phase-out product. Due to the larger social ownership of the aircraft, such as all the updates, the higher cost. In order to improve its sand mixing efficiency and reduce energy consumption, we started to reform the technical scheme since 1987 and carried out technical and economic feasibility studies on the scheme. The main idea of modification is: modified products and the original S114
