唐钢庙沟铁矿3台φ1750圆锥破碎机原设计采用5m×m板式热交换器进行系统润滑油冷却,但在使用中发现该冷却器存在易堵塞、难维修、消耗高、使用寿命短、工况要求严等缺点,严重影响润滑油冷却润滑效果,极易引发生产设 In the original design of φ1750 cone crusher of Tangteng Miaogou Iron Mine, 5m × m plate heat exchanger was used to cool the system oil. However, it was found that the cooler was easy to be blocked, difficult to maintain, high in consumption, short in service life, Strict requirements of working conditions and other shortcomings, a serious impact on lubricating oil cooling effect, can easily lead to the production of equipment
