试验表明：圆形活塞原理（即Ｗａｎｋｅｌ转子）不适用于机械真空泵的结构。经过对各种类型园形活塞设计的研究，最后确定研制余摆线泵。这种泵具有超余摆线（ｈｙｐｔｙｏｈｏｉｄ）形状的转动活塞。由这种方式构成的泵其抽速可达４００～６３０米～３／小时。第一批产品已在冶金工业、化学工业以及真空食品包装等工业部门试用。目前正在建立生产线。而抽气量高达２０００米～３／小时的大容量系也在设计和制造中。余摆线泵总的特点是动平衡好，因而噪音低，尺寸也比其它具有同样抽气量的泵小，另外还具备启动快、不用齿轮和皮带传动、泵体无漏气以及贮油容量大等优点。
Experiments show that the circular piston principle (ie Wankel rotor) is not suitable for mechanical vacuum pump structure. After various types of circular piston design of the study, and finally determine the development of trochoid pump. This pump has a rotating piston in the shape of a hyptyohoid. Pumps constructed in this way can pump up to 400-630 m³ / h. The first batch of products has been in the metallurgical industry, chemical industry and vacuum food packaging and other industrial sectors trial. Currently a production line is being established. The pumping capacity of up to 2000 m ~ 3 / hour of large-capacity system is also in the design and manufacture. Totally cycloid pump is characterized by good dynamic balance, and thus low noise, size than other pumps with the same exhaust volume is small, also has a fast start, no gear and belt drive, the pump without leakage and large oil storage capacity Etc.
