The viscosity of a fluid can be expressed as a physical quantity of viscosity. Commonly used dynamic viscosity Shore (referred to as viscosity) and kinematic viscosity v two. In addition, it can also be expressed in Saybolt viscosity of viscometer (Saybolt). The unit conversion relationship is shown in the following table: Note: lPa.s = 1000mPa.s = 1000 centipoise (cP), lmm2 / s = 1cSt. SSU (Saybolt Seconds Universal): for medium viscosity liquids. SSF (Saybolt Seconds Fur01): For high viscosity liquids. For 70cSt and above the viscosity values: lcSt = 0.216SSU; 1SSU = 10SSF. 2. Effect of Liquid Viscosity on Pump Performance For a vane pump, as the viscosity of the liquid increases, its flow rate, head lift, and power consumption increase (see Figure 2-121). For positive displacement pumps, as the viscosity of the liquid increases, the amount of leakage typically decreases, the volumetric efficiency increases, and the pump flow increases. However, the overall efficiency of the pump decreases and the power consumption of the pump increases. 3. The applicable range of viscosity for different types of pumps is shown in the table above.
Micro-electric motor brush life expectancy shorter than the large-scale electrical machinery, but the use of household appliances is shorter, therefore, a group generally can use the brush a few years in the life of electrical brush need to be replaced during the examples of many .
Material from the brush of a general can select a low friction coefficient and contact voltage drop of larger graphite electric brush, resin binder for the high resistance of natural graphite brush can be used for the poor motor. In addition, more abrasive strong carbon-graphite brush is mainly used mica sudden ultra-small motor.
