长螺旋输送机作为一种物料输送设备,应用比较广泛。我厂苇浆漂白工段三台长螺旋输送机在使用过程中,中间轴承处经常断裂,经分析找出了解决问题的方法,改善了设备的性能。 1.设备特征与问题 螺旋输送机的主要性能参数为:跨度10.5米(设有两个悬吊式中间轴承);螺旋直径φ400毫米;螺旋转速120转/分;输送浆浓10～12％;输送浆量60～80吨/时;传动功率:13kW。其工作环境为强腐蚀性。 长螺旋主轴分为三段制做(图1),中间采用“短节”刚性联接,并设悬吊式中间轴承两个。整机采用不锈钢材料制做。使用过程中存在的问题主要表现在中间轴承上:
Long screw conveyor as a material handling equipment, widely used. Reed pulp bleaching section of the plant three long screw conveyor in use, the middle bearing often rupture, the analysis found the way to solve the problem, improve the performance of the equipment. 1. Equipment Features and Problems The main performance parameters of the screw conveyor are: span of 10.5 m (with two suspended intermediate bearings); screw diameter φ400 mm; screw speed of 120 rpm; conveying pulp consistency of 10-12% Conveying capacity of 60 to 80 tons / h; Transmission power: 13kW. Its working environment is highly corrosive. Long Spiral Spindle is divided into three sections (Figure 1), the middle of the “short section” rigid connection, and the suspension of the middle of the two bearings. The whole machine is made of stainless steel. Problems in the use of the main performance in the middle bearing:
