多年来我公司对HJ 200类型灰浆搅拌机产品的密封装置进行了改造,把原有锥形紧圈贴配摩擦套再加油封的多级式密封结构,改为靠皮圈压垫弹簧座推压两生铁套摩擦式的密封装置,并在自制的200公升灰浆机中采用。不论是经过改装的灰浆机,还是新制的灰浆机,各种性能指标均达到同类产品的标准,而且新式密封装置的一次性使用周期大大超过老式的密封装置。在开始试用弹簧压圈式密封装置时,保养维修方面仍不够理想,经过多次改革,现已改置如图所示的结构。
Over the years, our company has modified the sealing device of the HJ 200 type mortar mixer, and replaced the original multi-stage sealing structure in which the taper ring is affixed to the friction sleeve and then the oil seal, instead of pressing on the apron pressure pad spring seat. Two-piece iron friction seals are used in homemade 200 litre mortar machines. Whether it is a modified mortar machine or a new mortar machine, various performance indicators have reached the standards of similar products, and the new-type sealing device has a one-time use cycle that greatly exceeds the old-fashioned sealing devices. At the beginning of the trial of spring-loaded ring seals, the maintenance and repairs were still not satisfactory. After several reforms, the structure shown in the figure has been changed.
