一种新型的中高压齿输泵——C B S 型齿轮泵,将在一些工厂陆续投产。这种齿轮泵有三种类型:1.普通型齿轮泵;2.带有轴向间隙自动补偿的齿轮泵;3.既带有轴向间隙自动补偿,又带有径向压力平衡的齿轮泵。这种齿轮泵的特点是采用滚针轴承、齿轮两侧装有耐磨损的双金属的侧板、对冲击员荷的适应性 A new type of medium and high pressure gear pump, C B S gear pump, will be put into production in some factories. There are three types of gear pumps: 1. General-purpose gear pumps; 2. Gear pumps with automatic axial-gap compensation; 3. Gear pumps with automatic axial-gear compensation and radial pressure balance. This gear pump is characterized by the use of needle roller bearings, wear-resistant bimetal side plates on both sides of the gear, and adaptability to impact loaders.
