Gear pump selection methods and precautions First, the gear pump, gear pump selection according to the specific requirements of customers to choose. Second, to find out what the gear pump, gear pump delivery medium, how much viscosity. Third, the gear pump, gear pump when the actual temperature is high. Fourth, the gear pump, gear pump, the actual working pressure requirements of how high the actual length of the pipeline, the highest point of how high the number of elbows in the middle of the pipeline. Fifth, according to the actual situation of customers reasonable calculation of the gear pump, gear pump in the actual pipeline resistance, how much pipeline loss. Sixth, gear pump, gear pump actual delivery of the media have no corrosive, the PH value of the specific medium is how much, and in actual use of the corrosiveness of the medium with temperature changes have not changed. Seventh, gear pump, gear pump medium is not lubricated, whether it contains particles or easy to crystallize. Eighth, gear pump, gear pump in the presence of positive and negative phenomenon. If it is sometimes used in reverse pumping, it should be indicated when ordering. Because the gear pump, gear pump with a mechanical seal is prohibited to reverse, and conventional gear pump, gear pump if the reverse use will gear pump gear shedding.
