Benefits of technology

This patented design improves on existing designs for an internal rotation type hydraulic power system used with vehicles or machinery. It achieves this through its unique features such as gripping together regular spirals within certain shapes without being connected altogether, ensuring steady flow even at high pressures while maintaining minimal sound during operation. Additionally, there's less complex components than traditional systems, making them more efficient from production costs compared to older versions.

Problems solved by technology

This patents describes various technical solutions for improving the performance of refrigerant compressors used in industrial applications such as air conditioning systems or hydraulic power generation facilities. These improvements include improved efficiency, reduced size, less expensive components while maintaining consistence quality standards over time. Additionally, these new technologies can also improve other aspects like reducing vibrations during operation without adding extra weight or making them more complicated.

Embodiment Construction

[0029] Example figure 1 As shown, the external rotation internal rotation constant pressure pump consists of a pump body 1, a spiral groove body 2, a universal rotation sleeve 3, an eccentric sleeve 4, an eccentric shaft 5, a ring track 6, a bearing 7, an oil seal 8, a transparent end cover 9, and The end cap 10 and the sealing ring are connected, and except the sealing ring, all other parts are rigid materials. The eccentric sleeve 4 is fixedly sleeved on the axial surface of the eccentric shaft 5, and the eccentric sleeve 4 and the eccentric shaft 5 are threaded or keyed, and can also be an integral structure. Since the eccentric sleeve 4 is a wearing part, it is separated The structure only needs to replace the accessories of the eccentric sleeve 4 to prolong the service life of the eccentric shaft 5, and the eccentric sleeve 4 can realize self-adjustment to meet the trajectory requirements of the spiral groove body 2 for planetary motion. The outer surface of the pump body 1

Abstract

The invention belongs to a method for designing an internal-rotation constant pressure pump structured as an external rotator, characterized in that: the inner surface of a pump body (1) is provided with a spiral groove with a rectangular normal section, a hollow cavity spiral groove body (2) is sleeved between the pump body (1) and an eccentric shaft (5), the outer surface of the hollow cavity spiral groove body is provided with the spiral groove which is identical in shape to and fits in size with the spiral groove at the inner surface of the pump body (1), the inner spiral groove is engaged with the outer spiral groove, the inner surface of the spiral groove body (2) is in sliding connection with the outer surface of the eccentric shaft (5) in a manner of arc fitting; the eccentric shaft (5) is connected with an end cap body of the pump body (1) via a bearing (7), the pump body (1) structured as the external rotator rotates while the eccentric shaft (5) is fixed, and two ends of the eccentric shaft (5) are respectively provided with channel ports for a liquid inlet or a liquid outlet. The internal-rotation constant pressure pump has the advantages of high output pressure, being capable of constant voltage change flow and mixed conveyance of liquid/gas, good interior sealing effect, small volume, low noise, low energy consumption and wide application range.
