working principle | The rotor pump adopts two synchronous rotors. The rotor is driven by a pair of synchronous gears in the box. Driven by the main and auxiliary shafts, the rotor rotates in the opposite direction synchronously, which changes the volume of the pump, thus forming a higher vacuum degree and discharge pressure. | A plurality of closed volumes are formed between the meshing screws and the shell, and each closed volume is one level. When the transmission shaft drives the main screw to rotate clockwise, the closed volume at the left end gradually forms, and the volume increases to the oil suction chamber; the closed volume at the right end gradually disappears, and the volume decreases to the oil pressure chamber. |

Working Principle of Lobe Pump | ||||||
Twin-Rotary pumps are multi-functional and bi-directional positive displacement pumps, produced with fine technology. The manufacturing engineering and precision of the pumps approach the advanced level of the world. Rotary pumps use synchronic rotors, driven by a pair of synchronic gears in the gear box. Transmitted by the main shaft and the sub-shaft. The rotors move synchronically in counter-clockwise directions, which, consequently, varies the pump capacity and builds up high vacuum capacity and emission pressure. It is particularly suitable to pump sanitary medium, high-corrosive and high-viscous medium. |
