Gear oil pumps and gear pumps with different tooth profiles are suitable for different occasions, which are embodied in the following aspects.
Gear oil pumps and gear pumps with different tooth profiles are suitable for different occasions. It is embodied in the following aspects.
1. Involute helical gear tooth profile gear pumps and gear oil pumps are common gear pumps. The tooth profile gear oil pumps and gear pumps are suitable for conveying low pressure and lubricating media with a viscosity range of 5cst-1500cst. The pressure is generally below 1.0MPa. In this type of gear pump, if the gears are shaving or grinding, the conveying viscosity can reach about 3000 cst under the condition of reducing the speed, and the pressure can meet 1.0 MPa.
2. Spur gear oil pumps and gear pumps. The delivery pressure of the gear oil pumps and gear pumps is higher than that of involute helical gear pumps. The normal discharge pressure is between 2.0-3.0. , Gear pump for gear shaving or gear grinding treatment, the discharge pressure can reach 4.0-6.0MPa.
3. The advantages of arc gear pumps are lower noise and higher efficiency than the first two. Use discharge pressure between 0.6-2.0. It is a gear oil pump with ideal results under normal pressure.
