Roots blower has a stable large pumping speed, which can quickly discharge the gas suddenly released, making up for the shortcomings of oil sealed mechanical pump and diffusion pump, and is suitable for use as a mechanical booster pump. It has a stable large pumping speed, and can quickly discharge the suddenly released gas, which makes up for the shortcomings of oil sealed mechanical pump and diffusion pump, and is suitable for use as a mechanical booster pump.
The load of Roots blower is too large and sometimes cannot be displayed immediately. Therefore, pay attention to the rising trend of air inlet pressure, bearing temperature and motor current to judge whether the machine works normally. For new machines or overhauled three blade roots blowers, the oil tank should be cleaned and operated according to the operating procedures. It is recommended to replace all lubricating oil after 8 hours of operation. In terms of safe operation and service life of roots blower, affected by many human factors, if maintenance and attention are paid at ordinary times, the service life and failure rate can be effectively improved.
1. Initial wear stage The initial wear stage is the stage of material wear. At this time, the uneven places on the surface between blower parts, as well as the oxide layer and decarburized layer, due to the operation of Roots blower parts, the mutual friction force is quickly smoothed. Because the impeller of Roots blower runs without friction in the body, it does not need lubrication, so that the discharged gas does not contain oil. It is the ideal pneumatic conveying gas source for chemical industry, food industry and other industries. At this time, the equipment can show high production efficiency, but this period of time is relatively short.
2. Normal wear stage This stage is the second stage of material wear. Generally, the wear of roots blower parts increases at a constant speed and slowly with time. The equipment can have high productivity and processing quality, and this stage takes a long time.
3. Sharp wear stage This stage is the third stage of material wear. At this time, the normal wear relationship has been destroyed, resulting in a sharp increase in wear. Later, the stainless steel blower parts were damaged and the equipment stopped. Roots blower is a volume operated blower. When in use, the flow changes little with the change of pressure.
However, the flow varies with the speed. Therefore, the selection range of pressure is very wide, and the selection of flow can be achieved by selecting the speed. As the impeller of Roots blower operates in the body without friction, it does not need lubrication, so that the discharged gas does not contain oil. It is the ideal pneumatic conveying gas source for chemical industry, food industry and other industries. Before that, the precision, performance and productivity of the equipment were greatly reduced. Therefore, in general, roots blower parts are not allowed to be used to severe wear stage. When roots blower parts tend to normal wear stage later, they should be repaired or replaced. This stage is also short.
I believe that after reading the above contents, you should also have a better understanding of the wear analysis of Roots blower parts. I hope it will be helpful to you.
