Knowledge anticorrosive pump fluid viscosity

When anticorrosive pump selection, not only flow, lift, temperature is the main parameters, such as viscosity is also need to consider the parameters of fluid viscosity in the pump selection is a very important parameter. Viscosity affects the calculation of pressure loss, pump speed, efficiency, power and so on. Viscosity is a fluid physical properties, any fluid viscosity. When fluid flow, there is relative motion, between adjacent fluid layer produces friction resistance between the liquid layer, become viscous force. Viscosity is used to measure the physical data of viscous force. Low viscosity, such as water, in the pipe flow more smoothly. Each molecule is a humanoid, imagine, fluid viscosity low molecule is like an athlete, flowing very fast. Fluid viscosity high, moved very slowly. And liquid viscosity are not fixed, usually with the increase of temperature and lower, with the increase of pressure. For a centrifugal pump, with the increase of liquid viscosity, its flow head would drop, increase of energy consumption. Return decreases with the increase of the for positive displacement pump, as the viscosity and volumetric efficiency increases, the pump flow rate increases, but the overall efficiency of the pump to drop, pump power increased. In petrochemical industry, selection of centrifugal pump, in general, we choose 20 ℃ water ( Kinematic viscosity of 1 CST) As the characteristic test of pumping medium. It is now accepted that, when more than 20 CST kinematic viscosity, water pump head and flow rate will drop slightly, power demand will increase sharply, the efficiency will be greatly reduced. Therefore, we should be accordingly the performance of the pump. Correction of water pump performance of two common methods: one is graphic method; Second, the formula of correction method. To introduce the formula under the correction method of steps. Formula correction method steps are as follows: 1, according to the corresponding computation formula parameters; 2, according to the corresponding equations pumping viscous liquid velocity correction; 3, according to the corresponding equations correction when pumping viscous liquid head; 4, according to the corresponding equations correction efficiency when pumping viscous liquid. According to the above four steps to correct the performance of the high viscosity oil transportation. Therefore, when pumping water pump performance and kinematic viscosity of viscous liquid is known, transportation of viscous liquid pump performance can be identified using steps 1 and 4. Method of course, there are more convenient, it is general water pump factory will provide selection software system, selection of software system with viscosity correction function.
