针对振动筛在现场应用中出现的筛网寿命短、跑浆、振动电动机的固定螺栓断裂、电气故障等问题,以S250系列平动椭圆振动筛为例,分析了出现上述问题的原因,并从现场安装调试和维护保养的角度提出了相应的解决方法,即设置合理的振动幅度,保证正确的电路连接,调节合适的筛箱角度,安装筛网时保证适当的张紧力,振动筛累计工作2月后对振动电动机上的轴承进行润滑,振动电动机损坏后正确地更换。
Aiming at the problems of short screen life, running pulp, breaking of fixed bolts of vibration motor and electrical faults in the field application of vibrating screen, taking S250 series of translational oval shale shaker as an example, the reasons for the above problems are analyzed. On-site installation and maintenance and maintenance point of view put forward the corresponding solution, that is, set a reasonable vibration amplitude, to ensure the correct circuit connection, adjust the appropriate angle sieve, install the screen to ensure proper tension, vibrating screen cumulative work After February, the bearings on the vibration motor are lubricated, and the vibration motor is properly replaced after being damaged.
