油封式机械真空泵(这里指旋片式和滑阀式,以下简称机械泵或泵)是历史最久,应用范围最广的真空获得设备之一。在科学试验和工业生产的多数真空设备中,都可寻觅到它的踪迹。国内生产厂大小十余家,产品从旋片泵的0.5升/秒到滑阀泵的1000升/秒,共十二个规格,二十多个型号,年产逾万 Oil-sealed mechanical vacuum pump (here refers to the rotary vane and slide valve type, hereinafter referred to as mechanical pump or pump) is the longest history, the most widely used vacuum access to one of the devices. It can be found in most vacuum equipment used in scientific experiments and industrial production. Domestic production plant size of more than 10 products from the rotary vane pump 0.5 liters / second to the sliding valve pump 1000 liters / second, a total of 12 specifications, more than 20 models, with an annual output of more than 10,000
