一、产品介绍:河北中正机械制造有限公司专业生产的3G三螺杆泵性能稳定,质量过关,泵体内部构造科学合理,使用安全,使用寿命长。3G三螺杆泵可输送温度不大于150摄氏度,粘度1.2-100OE(3.0-760cst),不含固体颗粒,无腐蚀性,具有润滑性能的介质。
二、工作原理:三螺杆泵分为3G通用型,3GC船用型及特殊型三种。内部主要构造是主动螺杆与从动螺杆组成,在运转时主动螺杆与从动螺杆上螺旋槽相互啮合,并且与衬套三孔内表面的配合,使三螺杆泵的进出口之间形成数级动密封腔室,从而将液体由泵进口处轴向移动到泵出口处,使所输送液体不断增压,从而形成一个平稳的连续的轴向移动的压力液体。
三、结构特点:
3G三螺杆泵可归结为以下几个特点:
(1)振动小,噪音小
(2)压力高,效率高
(3)体积小,重量轻,易移动
(4)构造简单,易拆装
(5)直线且连续输送,无搅拌
(6)轻微磨损,使用寿命长
3G三螺杆泵一般均采用机械密封,通过爪型联轴器与电机相连,使电机驱动带动泵体运转。面对泵体主轴的外伸一端,顺时针为正确的旋转方向。
