Volumetric rotary pump

본 발명은 회전식 용적형 펌프에 관한 것으로서, 특히 소형이면서도 많은 유량과 높은 양정(楊程)에 적합하며, 저속회전 및 고속회전에서도 우수한 성능을 발휘할 수 있는 유체압축기용 회전식 용적형 펌프에 관한 것인 바, 본 발명은 많은 유량과 높은 양정에 적합한 펌프로서 다량의 유체를 높은 위치까지 이동시킬 수 있으며, 또한 용적형 즉 용적의 변화를 이용한 펌프이므로 높은 효율로 작동하여 저속회전 또는 고속회전에서도 효율의 저하가 일어나지 않을 뿐만 아니라, 완전평형 회전기구를 형성하고 있기 때문에 고속회전에서도 구성부품의 회전 불평형에 의한 진동이 일어날 염려가 없으며, 또 저속회전과 고속회전에서도 다른 종류의 펌프에서 발생되는 단점을 보완할 수 있기 때문에 넓은 범위의 용도에 맞는 펌프로서의 고성능을 발휘할 수 있다. 따라서 소형의 장치로 고성능을 필요로 하는 각종 유체기계에 유용하게 적용하여 사용할 수 있는 등의 특징이 있다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary displacement pump, and in particular, to a rotary displacement pump for a fluid compressor capable of exhibiting excellent performance even at a low speed and a high speed, while being suitable for a small flow volume and a high head. , The present invention is a pump suitable for a large flow rate and high lift, and can move a large amount of fluid to a high position, and also because it is a pump using a volume change, that is, a change in volume, it is operated at high efficiency to reduce efficiency even at low speed or high speed rotation. Not only does this happen, but because it forms a fully balanced rotating mechanism, there is no fear of vibration caused by the unbalance of components even at high speeds, and it can compensate for the disadvantages of other types of pumps even at low speeds and high speeds. As a result, it can exhibit high performance as a pump suitable for a wide range of applications. The. Therefore, it can be usefully applied to various fluid machines requiring high performance as a compact device.

Screw spindle pump arrangement

The invention relates to a screw spindle pump arrangement having a low-pressure connection, a high-pressure connection, a drive spindle, and at least one idling spindle. A feed section of the idling spindles can be divided into two feeding segments that can be driven either in series or in parallel. A screw spindle pump arrangement is thereby created with little effort, wherein two operating modes can be selected without controls technology. Two tap connections that can be connected by a connecting line are provided in a center area of the feed section. The connecting line can be blocked and the low-pressure side tap connection can thereby be connected to the high-pressure connection, and the high-pressure side tap connection can be connected to the low-pressure connection. A series circuit (high pressure, low volume flow rate) is created by the open connecting line, corresponding to a screw spindle pump according to the prior art. With the connecting line blocked, and the simultaneous pressure medium flow paths indicated above, the screw spindle pump arrangement can be simply operated as a parallel circuit (low pressure, high volume flow).
