Internal gear pumps are highly efficient and stable gear pumps characterized by two gears meshing with each other in a tightly fitted casing to achieve suction and discharge of liquids. Due to its high efficiency and stability, internal gear pumps are widely used in many fields.
Working principle of internal gear pumps
Internal gear pumps are mainly composed of two gears that bite each other and a shell. Inside the casing, the teeth of the two gears cooperate with each other to form a closed space, when the gears rotate, this closed space will change, so as to realize the liquid suction and discharge. Specifically, when the two gears bite each other, a closed space is formed, and this space will be expanded or reduced with the rotation of the gears, so as to realize the suction and discharge of liquid.
Advantages of internal gear pumps
High efficiency and stability: with high efficiency and stable flow rate, the internal gear pump can ensure continuous and stable fluid transfer.
