Embodiment Construction
[0032] The specific implementation of the present invention will be described below in conjunction with the drawings and examples.
[0033] Figure 1~5 A schematic diagram of the structure of the present invention is shown. An internal gear pump with radial compensation, comprising an internal ring gear 11 and an external gear 5 meshing with the tooth top 19 of the internal ring gear, the external gear 5 is supported in the pump casing around a parallel axis, so The teeth of the two gears surround a crescent-shaped space that gradually narrows on both sides and is symmetrical. On one side of the space, a large crescent block 34 and a small crescent block 27 are arranged. The large crescent block 34 and the small crescent block 27 make the pump The interior is divided into a high pressure zone 59 and a low pressure zone 58 .
[0034] figure 1Among them, the pump housing of the internal meshing gear pump is composed of a pump body 3, a left connecting cover 2, a right connect...
