为了防止破碎矿石时产生的灰尘进入碗形轴瓦和传动机构,以及保护循环润滑油的清洁,而在圆锥破碎机体内部设有水封防尘装置。鉴于该装置设在破碎机工作部位,进排水管道均要通过破碎腔下部,破碎后的矿石下落时,会撞击磨损这些管道和管道弯头,时间久了,往往会打破而漏水。1979年我矿一台PYD2200短头弹簧圆锥破碎机,曾因进水 In order to prevent the dust generated when crushing ore into bowl-shaped bush and transmission mechanism, as well as to protect the circulation of lubricating oil cleaning, and in the cone crusher body with water seal dust-proof device. In view of the device is located in the crusher work site, into the drainage pipes have to crush through the lower part of the crushed ore drop will hit the wear and tear of these pipes and pipe elbow, over time, often breaking and leaking. In 1979, I mine a PYD2200 short head spring cone crusher, was due to water
