What is an internal gear pump, the purpose and introduction of an internal gear pump

Internal gear pump is a common forward displacement pump, consisting of two meshing gears inside and outside. The internal gear pump rotates the internal gear, while its teeth mesh with the external gear, to suck fluid in from the inlet and push it to the outlet, achieving liquid delivery. Internal gear pumps have the advantages of simple structure, stable operation, adjustable flow rate, and high pressure.

Internal gear pumps are mainly used in hydraulic transmission, lubrication systems, oil injection systems, mixing equipment and other fields. Among them, the hydraulic transmission field is one of the main application areas of internal gear pumps. Internal gear pumps can be used as a power source in hydraulic systems, extracting hydraulic oil from the tank and compressing it before sending it to hydraulic actuators. In addition, internal gear pumps can also be used in engine lubrication systems to extract lubricating oil from the oil pan and compress it before sending it to various parts of the engine, ensuring smooth and safe engine operation.

In short, internal gear pump is a widely used pump type in the industrial field, which can be used to transport different media and meet the needs of different flow rates and pressures.
