一、螺杆泵轴套抱死的原因分析
根据滑动轴承的工作情况,一般衬套孔与轴配合是间隙配合,零件图上轴径与衬套孔径的尺寸偏差,一般是按平均工作温度20℃时保证轴与衬套孔间具有合理间隙变化而确定的。影响滑动轴承过热故障的因素很多,在轴承结构设计合理,材料选用正确的情况下,滑动轴承过热主要是轴承径向间隙的大小装配不当及使用不当造成的。
G型螺杆泵产品概述
G type screw pump product overview
单螺杆泵在发达***已广泛使用,国外多数称单螺杆泵为“莫诺泵”《MONOPUMPS》,德国称为“偏心转子泵”。由于其优良的性能,近年来在国内的应用范围也在迅速扩大。
1Single screw pump has been widely used in developed countries, most of the foreign said single screw pump as 'Monod pump' 'MONOPUMPS', Germany called 'eccentric rotor pump'. Because of its excellent performance, in recent years, the scope of application in China is also rapidly expanding.
它的特点是对介质的适应性强、流量平稳、压力脉动动小、自吸能力高,这是其它任何泵种所不能替代的。
It is characterized by a strong adaptability to the media, ***ooth flow, pressure pulsation, 1***all, high self absorption capacity, which is not a substitute for any other pump.
