A. The gear oil pump has a higher rotation speed than the Roots oil pump compared with the Roots oil pump speed. The theoretical rotation speed of the gear oil pump is 960 r/min--1450 r/min, and the theoretical rotation speed of the Roots oil pump is 50 r/min--500 r/min.
B. The difference between the internal gear teeth of the gear oil pump and the Roots oil pump is an external gear pump and an external gear rotor pump. Gear oil pumps generally use involute helical gears after point contact arc gears; Roots oil pumps use eight-shaped rotor or plum-type rotor gears.
C. The gear oil pump is not easy to transport high viscosity media, and the Roots oil pump can easily transport high viscosity media. The gear pump is larger than the Roots pump because the gear pump has a larger number of rotations than the Roots pump and has a different gear structure. Therefore, in general, the Roots oil pump has a higher viscosity than the gear oil pump.
D. The gear oil pump is difficult to transport impurities, and the Roots oil pump replaces the difficulty of the gear oil pump to transport impurities. Due to different gear oil pump structure, internal teeth and Roots oil pump, the Roots pump has a large gear module and the gear pump has a small module, so it is difficult for the gear pump to convey the medium of impurities, and the Roots pump can, Feng Ting company It is recommended that you use a Roots pump when transporting high-viscosity impurities.
