内齿旋转泵属于容积泵,采用转子和空转齿轮总成产生流动。该总成具有补偿性,采用与内齿轮相邻的新月形,全部位于外齿轮之中。转子齿轮驱动惰轮齿轮,新月形所形成的空间补偿齿轮,齿轮啮合泵送流体,将流体排至排出口。该装置适用于哪些用途和流体?内齿旋转泵一般规定用于粘稠流体,譬如油品、沥青、脂肪、糖浆、巧克力以及树脂,产品粘度越高,上述工作原理的容积效率就越高。可以处理粘度达到100,000cSt的流体!

How do internal rotary gear pumps work?

An internal rotary gear pump employs a positive displacement principle. The pump features a casing in which a dual gear (an outer rotor gear and an internal idler gear) and crescent assembly is housed. As the rotor gear begins to turn, the idler gear rotates with the teeth beginning to mesh accordingly. It is the space between these gears and the meshing action which both draws in the fluid and displaces it. The crescent shape both offsets the idler gear and provides a seal between the suction and discharge ports.
