齿轮油泵与罗茨油泵之间的主要区别 A.齿轮油泵与罗茨油泵转数相比，齿轮油泵的转数要比罗茨油泵的转数高。齿轮油泵的理论转数是960r/min--1450r/min，罗茨油泵的理论转数在50r/min--500r/min。 B.齿轮油泵和罗茨油泵内齿区别一个是外啮合齿轮泵，一个是外啮合转子泵。齿轮油泵一般采用渐开线斜齿后点接触圆弧齿轮；罗茨油泵选用8字形转子或梅花型转子齿轮两种。 C.齿轮油泵不易于输送高粘度介质，罗茨油泵易于输送高粘度介质。齿轮油泵要比罗茨油泵输送的量大些，由于齿轮油泵比罗茨油泵转数大、齿轮结构不同。所以一般情况下罗茨油泵比齿轮油泵输送的介质粘度大。 D.齿轮油泵输送杂质比较困难，罗茨油泵代替了齿轮油泵输送杂质时的困难。由于齿轮油泵结构、内齿和罗茨油泵不同，罗茨泵的齿轮模数大，齿轮泵的齿轮模数小，所以齿轮泵输送杂质的介质比较困难，而罗茨油泵即可，丰庭公司建议输送高粘度杂质介质时建议大家选用罗茨油泵。

The main difference between the gear pump and Roots pump A. The gear oil pump and Roots pump rpm compared to the number of revolutions of the gear pump to the high number of revolutions of the Bi Luoci pump. The theory of revolutions of the gear pump is 960r/min--1450r/min, the theory of revolutions of the Roots pump 50r/min--500r/min. B. The gear oil pump and Roots pump tooth difference between an external gear pump, an outer meshing rotor pump. The gear pump is generally used to point contact arc gear involute helical gear; the Roots pump selection of 8-shaped rotor or plum rotor gear two. C. The gear pump is not easy to transport high-viscosity media, the Roots pump is easy to transport high-viscosity media. Transmission gear oil pump to pump in Bi Luoci large, the number of revolutions of the gear pump Bi Luoci pump, the gear structure. Roots pump under normal circumstances than the gear pump transmission medium viscosity. D. Gear pump conveying impurities is more difficult, the Roots pump instead of a gear pump conveying impurities difficult. Gear pump structure of the tooth and the Roots pump, Roots pump gear mode the number of large, small modulus of the gear of the gear pump, gear pump impurities media is difficult, and the Roots pump can Feng court recommended conveying the medium of high viscosity impurities suggest that you use a Roots pump.
