92年我厂新增的两台200m~3发酵罐,配有NGW—L—207型行星齿轮减速箱,减速箱润滑采用CB—B16型油泵强制循环润滑.原设计在油泵与减速箱水平输油管道之间,装一“玻璃管示油器”,因为设备高大,“示油器”距操作人员至少在3.5m以上,观察极不方便,中、夜班时几乎无法辨认.在生产的初期,常因润滑油脏,滤油器被堵,造成供油不正常而影响生产.运行中一旦出现机械事故引起“倒罐”,经济损失惨重.为保证设备正常安全运转,减轻工人负担,便于监控,针对上述问题,我们拆除原设玻璃管示油器,在输油管90℃拐弯处自行设计加工了一个“阻力阀”,如图所示.阻力阀增设,使油泵输出的压力油,由原来的“畅通无阻”输出,变为流经阻力阀时增加一定的阻力,井将阻力通过油管引向地面压力表.压力表安装在工艺系统仪表的侧面,这样操作工人便可以以观察工艺仪表时很方面的同时兼顾.与此同时压力表的显示值可通过阻力阀来调整.据我们使用经验,冷车启动油温低,压力值调在0.3MPa,正
In 1992, our factory added two 200m ~ 3 fermenters with NGW-L-207 planetary gearboxes, and the gearboxes were lubricated by CB-B16 oil pump forced circulation lubrication.The original design of the oil pump and gearbox horizontal pipeline Between the Road, installed a “glass tube oil cooler”, because the equipment is tall, “oil” from the operator at least 3.5m above the observation is very inconvenient, in the midnight, almost illegible.In the early stages of production, Often due to dirty oil, oil filter is blocked, resulting in abnormal oil supply and affect the production. In the event of mechanical accidents caused by “inverted” heavy economic losses. In order to ensure the normal operation of equipment, reduce the burden on workers, easy to monitor , In view of the above problem, we demolished the original glass tube oil, in the pipeline 90 ℃ bend at its own design and processing of a “resistance valve”, as shown in the figure.Radio valve to increase the output pressure of the oil pump, from the original “Unimpeded” output becomes a resistance that increases through the resistance valve and leads the resistance through the tubing to the surface pressure gauges. The pressure gauges are mounted on the side of the process system gauges so the operator can observe the process gauges Aspects When both. Gauge display value while the resistance can be adjusted by a valve. According to our experience, the cold start oil temperature is low, the pressure adjusting 0.3MPa, n
