摘要

3RP20凸轮转子泵是一种容积泵，通过一对传动比为1的齿轮啮合传动，带动两个转子实现同步反转。在旋转过程中，入口产生真空度，从而吸入待输送的液体。通常也称为非接触式3RP20凸轮转子泵。其原理是泵体内的两个转子由两个同步齿轮驱动旋转完成吸排水。对于双叶渐开线3RP20凸轮转子泵的研究，具有十分广阔的应用前景。它不仅适用于石油介质运输，而且在日用化工、石油、医药、食品等行业具有广阔的市场潜力。可输送蜂蜜、牛奶、润滑油等大粘性介质和煤、原油等多相介质。如：润滑油、油脂、原油、沥青、油漆、植物油、蜂蜜、果酱、黄油、牙膏、洗发水、肥皂、油漆、石蜡、尼龙、聚酯、聚乙烯等。

鉴于我国目前对3RP20凸轮转子泵转子型线设计的理论研究较少，本文着重对转子型线的理论研究。为了提高泵的性能，研究了双叶片渐开线3RP20凸轮转子泵的基本技术，并对其结构进行了优化。双叶片渐开线3RP20凸轮转子泵的设计。

3RP20凸轮转子泵具有工作原理简单、体积小、重量轻、成本低、密封安全、无污染等特点。它不仅适用于石油介质运输，而且在日用化工、石油、制药、食品等行业具有广阔的市场潜力。因此，3RP20凸轮转子泵在某些场合可以很好地替代螺杆泵和离心泵。

Abstract

The 3RP20 cam rotor pump is a volumetric pump that reverses two rotors through a pair of gears with a ratio of 1. During rotation, the inlet creates a vacuum that draws in the liquid to be delivered. Also also known as a non-contact 3RP20 cam rotor pump. The principle is that the two rotors in the pump are driven by two synchronous gears to complete the suction and drainage. The study of the involute 3RP20 cam rotor pump has great application prospect. It is not only suitable for petroleum medium transportation, but also has broad market potential in daily chemical industry, petroleum, medicine, food and other industries. Can transport honey, milk, lubricating oil and other large viscous media and coal, crude oil and other multi-phase media. Such as: lubricating oil, oil, crude oil, asphalt, paint, vegetable oil, honey, jam, butter, toothpaste, shampoo, soap, paint, paraffin, nylon, polyester, polyethylene, etc.

In view of the few theoretical research on the rotor line design of 3RP20 cam rotor pump in China, this paper focuses on the theoretical research of the rotor line. To improve the performance of the pump, the basic technology of the double-blade involute 3RP20 cam rotor pump is studied and its structure is optimized. Design of 3RP20 cam rotor pump.

3RP20 cam rotor pump has the characteristics of simple working principle, small volume, light weight, low cost, safe sealing, no pollution and so on. It is not only suitable for the transportation of oil media, but also has a broad market potential in the daily chemical industry, petroleum, pharmaceutical, food and other industries. Therefore, the 3RP20 cam rotor pump can be a good alternative for screw pumps and centrifugal pumps in some situations.

Key words: 3RP20 cam rotor pump; rotor line; structure design; design calculation; rotor pump
