Roots pump advantages and disadvantages which

Roots pump can deliver tens of thousands of centipoise of viscosity liquid, Roots pump work through a pair of synchronous gear drive, in the pump body bite each Other. Today, these products are mainly used in petroleum, chemical, pesticides, plastics and other fields, and achieved very good results. Roots pump features are also used with the Roots pump has been more and more attention, then Roots pump advantages and disadvantages which? Roots pump advantages and disadvantages which Roots pump advantages: fast start, less power consumption, low maintenance costs, pumping speed, high efficiency, is pumping gas contained in a small amount of water vapor and dust insensitive to 100 ~ 1 Pa pressure range has a larger pumping rate, can quickly rule out the sudden release of gas. This pressure range is just between the oil-sealed mechanical vacuum pump and the diffusion pump. Therefore, it is often connected in series between the diffusion pump and the oil-sealed mechanical vacuum pump to increase the amount of suction in the intermediate pressure range. It is also known as a mechanical booster pump. Roots pump Disadvantages: too much oil, easy to make the temperature increase, the oil is too small, easy to cause poor lubrication, for a higher vacuum Roots vacuum pump (mechanical booster pump) can not be directly into the atmosphere, such as the atmosphere Will cause Roots vacuum pump suction port and exhaust pressure is too large, so Roots vacuum pump overload, such as simply increasing the Roots vacuum pump motor power will cause the Roots vacuum pump overheating and Roots vacuum pump rotor gap between Very soon due to thermal expansion and stuck. With the rapid development in the fields of industry, agriculture, chemical industry and aerospace, the progress of many related equipment in these fields has also drawn great attention. For example, the research on Roots pumps has been gradually upgraded from the original working performance to the characteristics of Roots pumps. Among them Roots pump advantages and disadvantages have become the user to buy products and use the product to focus on the issue.
