C－076－1型灰浆搅拌机普遍存在着封浆装置漏浆的弊病，原封浆装置结构（见图1）的主要缺陷是紧圈2与盘根压盖3在运转中存在相互摩擦磨损，砂浆可沿着轴套8与盘根9的配合间隙向轴颈渗入，使用8~10个月后，轴与轴承间就严重磨损，每台修理费需1000元，并降低设备利用率，影响施
The C-076-1 type mortar mixer generally suffers from the drawbacks of slurry leakage from the sealing device. The main drawback of the original slurry sealing device structure (see Fig. 1) is that friction between the tight ring 2 and the packing gland 3 during operation exists. It can infiltrate into the journal along the clearance between the sleeve 8 and the packing 9. After 8 to 10 months of use, the shaft and the bearing wear together. Each repair cost is 1,000 yuan, and the equipment utilization rate is reduced.
