Discussion on the main energy saving properties of the rotary vane vacuum pump

2018/6/4 11:54:20 Viewers:
The rotary vane vacuum pump is a high vacuum pump. It can be used alone or as a front pump for other high vacuum pumps or ultra high vacuum pumps. It has been widely used in metallurgy, machinery, military industry, electronics, chemical industry, light industry, petroleum and medicine. Below, Shenzhen rotary vane vacuum pump manufacturers discuss with you about the main application quality of rotary vane vacuum pump.


The speed regulation of the 1. rotary vane vacuum pump is one of the measures to ensure the running of the rotary vane vacuum pump in the high efficiency area. In order to adapt to the different working conditions, change the performance curve of the rotary vane vacuum pump, besides the impeller cutting, the speed regulation is also a common method.


2. in view of the difference between the rated lift and the actual running head of the rotary vane vacuum pump, it is an effective way to improve the operating efficiency of the rotary vane vacuum pump by cutting the outer diameter of the working wheel, reducing the lift and flow to make it consistent with the actual lift, and changing the design work point of the rotary vane vacuum pump.


3. reducing the roughness of the overflow component of the rotary vane pump, reducing the friction loss of the flow, and polishing the inner surface of the impeller and the inner surface of the pump, can improve the efficiency of the rotary vane vacuum pump, and the energy saving is about 1%. If the coating is coated with smooth coating, the energy saving effect will be more obvious to about 5%.

4. the cutting of the impeller: the rated lift of the rotary vane pump in the pumping station is not consistent with the actual lift in the water supply plant because of some changes in the rated lift of the rotary vane pump. The rotary blade vacuum pump impeller cutting is a contradiction between the type of the rotary vane vacuum pump, the limitation of the variety specifications and the diversity of the water supply to the image.  Selection method. It enlarges the application range of rotary vane vacuum pump and adjusts the working characteristics of rotary vane vacuum pump by cutting impeller to make it work in a reasonable range.


5. compared with the effect of several measures to implement energy saving, in addition to adjusting the reasonable allocation of flow and lift, cutting the working wheel, the cost of applying smooth coating is lower and the efficiency is the highest.


6. other: mainly reduce the mechanical loss of the rotary vane vacuum pump, such as the friction loss of the shaft seal and bearing, and use the soft sealing cushion, and pay attention to reducing the transmission loss of the rotary vacuum pump. In addition, the scientific and economic dispatch of the management layer can improve the water level of the front pool, pay attention to the balance of water production and water supply in the peak period, make a comprehensive analysis on the pump house unit in time and optimize the combination to make the rotary vacuum pump unit run at the best operating point.
