蒸汽机车131复式风泵突停和打风效率低,是机车运用中较普遍存在的问题,它影响机车质量和工作效率,又严重威胁着行车安全。新邱露天矿广大工人、工程技术干部在生产中靠科学、讲实践,风泵由铸铁涨圈改为无油润滑涨圈,通过近两年实践认为:此涨圈适合煤矿机车用风泵打风的翻车启动,具有打风快、泵体不发热、故障少、节油等特点。 Steam locomotive 131 double air pump sudden stop and hit the wind is inefficient, is the locomotive more common problems that affect the quality and efficiency of locomotives, but also a serious threat to traffic safety. New Qiu open-pit mine majority of workers, engineering and technical cadres rely on science in production, stresses the practice, the wind pump from the ring up to the non-oil lubrication up ring, practice that over the past two years: This ring is suitable for coal mine wind pump Wind rollover start, with playing wind fast, the pump body does not heat, less failure, fuel-efficient and so on.
