下面报道的是济南机车工厂型砂气力输送试验总结。该厂这套装备已于1966年11月份正式投入生产,效果良好。生产装置较试验装置增设了一个储风罐,发送器的装砂门由手动改为风缸启闭,设置了三个卸料器。管道总长度71米,在发送器输出管中部设置了一个涡流式升压器,并在管道的30米处又设置了第二个升压器。每输送500公斤型砂只需15—30秒钟输送压力只要在2公斤/厘米~2以上即可顺利地进行输送。该厂现在使用的生产装置,机械化程度较高,有较好的防尘作用。全套装置的投资,在利用废料的情况下,只花了一千多元。目前每班可节省人工1——2人。
The following report is a summary of Jinan locomotive factory pneumatic conveying experiment. The plant this set of equipment was officially put into production in November 1966, the effect is good. The production device is equipped with a storage tank than the test device. The sand loading door of the transmitter is changed from manual to open and close, and three unloaders are set. The total length of the pipeline is 71 meters. A vortex booster is installed in the middle of the transmitter output pipe, and a second booster is installed 30 meters away from the pipe. Each conveying 500 kilograms of sand only 15-30 seconds delivery pressure as long as 2 kg / cm ~ 2 or more can be smoothly transported. The plant now using the production plant, a higher degree of mechanization, have a good dust-proof effect. The investment in a full set of equipment has only cost over a thousand dollars when using waste materials. The current class can save artificial 1-2 people.
