Introduction of gear molten salt pump
    In molten salt test system, if the molten salt pump flow needs to be measured, or molten salt pump flow is very small, head is very high, this case should be used to gear molten salt pump, following a brief introduction.
   The concept of gear pump for molten salt is very simple, namely, its most basic form is the same size of the two gears in a close fitting shell meshing rotary, the shell's internal similar "8" shape, the two gears are installed inside, gear diameter and the both sides and the shell body to fit tightly. From the extrusion machine material in the intake into the two intermediate gears, and full of the space, with the tooth rotation moving along the shell, finally discharged when the two gears mesh.
    Molten salt export of molten salt continuous fluid of molten salt in terminology, the gear pump is also called positive displacement device, such as a cylinder piston, when a tooth to another tooth space, liquid by mechanical pressing and discharging. Because the liquid can’t be compressed, so the liquid and the tooth is not in the same time to occupy the same space, so that molten salt is excluded. Because the tooth meshing, this phenomenon is continuous in the event, and also in the gear pump provides a continuous exclude the amount of molten salt pump rotates a circle, the discharge amount is the same. With the drive shaft of uninterrupted rotation, the pump is continuously discharged fluid. Gear pump flow and pump speed.
    In fact, there is a small amount of fluid loss in the gear pump for molten salt, which makes the operating efficiency of the pump can’t achieve 100%, because these fluids are used to lubricate the bearings and gears on both sides, and the pump body is also not may gapless matched, so as not to make 100% of the fluid discharged from the export, so a small amount of fluid loss is inevitable. However gear pump for molten salt can still run well, the majority of extrusion materials, can still reach 93% ~ 98% efficiency.
    But for the gear pump in the actual design, should fully consider the impact of high temperature on the pump.
