北方铜业铜矿峪矿选矿厂现有PYBφ2200型弹簧圆锥破碎机2台,PYDφ2200型弹簧圆锥破碎机3台,共同承担着中、细碎破碎铜矿石的任务。1问题的提出为了防止粉尘进入机器内部的摩擦表面,原设备在球面轴承座设计了水封防尘装置。如图1所示,防尘水从进水管8进入储水槽,充满后水自溢流入排水槽内,再由排水管1排出机外。由于球形圈2的下缘插入储水槽,当粉尘附着在球形圈上时,即被带入水 North Copper Copper Mine ore processing plant existing PYBφ2200-type spring cone crusher 2, PYDφ2200-type spring cone crusher 3, share the fine crushing copper ore mission. 1 problem put forward In order to prevent dust from entering the friction surface of the machine, the original equipment in the spherical bearing seat designed dust seal device. Shown in Figure 1, dust-proof water from the inlet pipe into the storage tank 8, filled with water from overflow into the drainage tank, and then discharged from the drainage pipe 1 outside. Since the lower edge of the spherical ring 2 is inserted into the sump, when the dust is attached to the spherical ring, it is brought into the water
