The main differences between gear oil pumps and roots oil pumps are as follows:
1. The difference between the internal gear of the gear oil pump and the Roots oil pump is the external gear pump and the external rotor pump. Gear oil pumps generally use involute helical gears and point contact arc gears; Roots oil pumps use two types of 8-shaped rotors or plum-shaped rotor gears.
2. Compared with the rotation speed of the gear oil pump, the rotation speed of the gear oil pump is higher than that of the roots oil pump. The theoretical speed of the gear oil pump is 960r/min--1450r/min, and the theoretical speed of the Roots oil pump is 50r/min-500r/min.
3. Gear oil pumps are difficult to transport impurities. Roots oil pumps replace the difficulties when gear oil pumps transport impurities. Due to the difference in the structure, internal teeth and roots oil pumps of the gear oil pump, the gear modulus of the roots pump is large, and the gear modulus of the gear pump is small, so the gear pump is more difficult to transport impurity media, while the roots oil pump can deliver high viscosity It is recommended that you choose Roots oil pump when the medium is impurity.
4. Gear oil pumps are not easy to transport high viscosity media, while Roots oil pumps are easy to transport high viscosity media. The gear oil pump has a larger capacity than the Roots oil pump, because the gear oil pump has a larger revolution than the Roots oil pump and the gear structure is different. Therefore, in general, the viscosity of the medium delivered by the Roots oil pump is higher than that of the gear oil pump.
The GZYB high-precision gear oil pump is the latest high-end gear oil pump product developed by the company. It breaks through the concept of traditional gear pump design and applies the hydraulic balance, shock absorption, noise reduction, anti-rotating parts napping and gluing, and anti-impurity independently developed by our company. , New technologies such as corrosion resistance.
