Description

Technical Field

[0001] The invention relates to the technical field of positive displacement pumps, in particular to a composite spherical pump. Background Art

[0002] At present, the suction of dual or multiple media generally adopts multiple pumps to pump at the same time. The disadvantages are that the system is large in size, power consumption is high, and the proportion of suction of different media cannot be accurately controlled. The spherical pump is a new three-dimensional variable volume mechanical structure. It is currently widely used in emergency fire fighting, oil monitoring, cleaning utensils, medical supplies, food machinery and other technical fields. It has the advantages of no inlet / exhaust valves, few moving parts, reliable sealing, strong self-priming ability, strong anti-fouling ability, etc. Multiple compressible studios can be formed in a spherical inner cavity to achieve multi-stage compression or suction of multiple media, which is suitable for various complex working environments. The existing spherical pump can meet both single-medium and multi-medium operating conditions. However, when the operating condition is multi-medium, the existing dual-medium mixed spherical pump uses a plurality of different compression working chambers formed by two media in the same spherical cavity. For example, the Chinese patent with the patent name "A multi-stage spherical compressor" and patent number ZL2024203432576 discloses that different compression working chambers are provided in the same spherical inner cavity. However, due to the internal leakage of the spherical inner cavity, the medium in different compression working chambers is easy to leak out, which may cause different media to mix in the spherical inner cavity. If the two media are easy to react, then the existing multi-media mixed spherical pump is not applicable, and the manufacturing of this multi-stage pump is relatively complex and the manufacturing cost is high. Summary of the invention

[0003] The present invention provides a composite ball pump, which is used to solve the problem that the existing single pump cannot simultaneously pump two or more different media, the media are easily mixed and reacted in the pump due to leakage, and the mixing ratio of the two media cannot be accurately controlled. At the same time, a single pump is used to replace multiple pumps to solve the problems of large size, high energy consumption and high noise of multiple pumps.
