选煤厂申克激振器自制密封件工具设计与加工

Design and processing of self-made sealing tools for Schenker exciter in coal preparation plant

激振器是振动筛的动力源,是选煤厂振动筛的核心部件,由于设备在复杂多变的物料加工情况下均出现不同程度损坏,损坏故障中轴承损坏和密封漏油居多,申克激振器在选煤厂振动设备中,使用效果表现较好,但故障后由于没有专用售后和维修基地且渠道不畅通,影响设备正常运转。对申克振动筛各型号毛毡密封设计专用加工制造机构,实现进口设备备件自主化加工,从实际使用效果来看,可与原装进口备件相媲美,使用周期长达8个月以上,实现了自主设计。

The vibrator is the power source of the vibrating screen and the core component of the vibrating screen in the coal preparation plant.Due to different degrees of damage in the equipment under the complex and changeable material processing conditions,among the damage failures,bearing damage and seal oil leakage are the most common.The Schenck vibrator has a better performance in the vibrating equipment of the coal preparation plant.However,after a failure,due to the lack of a dedicated after-sales and maintenance base and the unsmooth channels,the normal operation of the equipment is affected.In this paper,a dedicated processing and manufacturing mechanism has been designed and processed for the felt seals of various models used in the Schenck vibrating screen,achieving the goal of independent processing of imported equipment spare parts.Judging from the actual use effect,it can be comparable to the original imported spare parts,and the service life is more than 8 months,realizing the original intention of independent design.
