Roots blower: it is a positive displacement fan. It is a pump body with two impellers built in. Due to the precise actual and installation position, the two impellers do not contact and interfere with each other when rotating. There is a small gap between them to generate pressure and flow. Because its pump body is large and long, the flow is relatively large, Direct connection or belt connection can be adopted;
The motor of Roots blower drives the driving shaft through V-belt (or coupling), and the driving shaft acts through the synchronous gear in the gearbox to make the two or three blade impeller in the machine rotate in the opposite direction. There is a certain working gap between the impellers and between the impellers and the engine body. When the two impellers rotate, the air volume in the engine body will be pushed from the air inlet chamber to the exhaust chamber without internal compression and then discharged from the engine body to achieve aeration. Roots blower, as a rotary machine, has relatively stable working characteristics. There are small gaps between the rotor and rotor of roots blower, between the rotor and pump body, and between the rotor and side cover, so there is no friction or contact wear in the working chamber; The three blade roots blower is economical and durable, without lubrication inside, with long service life and good dynamic balance. There are six suction and exhaust processes in a week of operation, with high volumetric efficiency. Simple structure, convenient use and maintenance, no need for internal lubrication, and the conveyed medium is oil-free. Not only the maintenance cost is saved, but also the service life is increased, so the capacity and energy saving effect is significant.
1. In order to save power and achieve high efficiency of the high-pressure roots blower, it is essential to reasonably select the model of the high-pressure roots blower, and select the parameters such as wind pressure and air volume that should be configured in the appropriate working environment, so as to prevent the high-pressure roots blower from operating in the low efficiency area.
2. Try to reduce the resistance of the pipe network, reasonably select the size of the pipe and the installation position of the pipe, and it is also recommended to select the imported collector with high quality.
3. For the independently applicable high-pressure roots blower impeller, it must be equipped with a suitable motor dedicated to the fan, so as to avoid the phenomenon that the output power of the motor equipment is not proportional to the load from the root.
4. The radial distance between the air duct and the top of the blade is also a factor affecting the power consumption of the high-pressure roots blower, which must be reasonably controlled.
I believe that after reading the above content, you should also have a better understanding of the ways to save energy and power of Roots blower. I hope it will be helpful to you.
