How do I select the - dry vacuum pump

dry vacuum pump is widely used. When choosing vacuum unit equipment, everyone must according to the actual situation, such as equipment layout, terrain, water conditions and economic plan, see the following instructions.

1。 According to the actual situation consider dry vacuum pump type and specification

2. Considering the special type of pump selection, in which after a series of pumps, choose to use or series of characteristic curve of patterning the specific model according to flow restrictions on the two main performance parameters of 5% 10%.

3。 According to the nature of the dielectric material is resistant to corrosion or equipment with the burst of;

4。 Considering the size of the vibration, the vibration can be divided into gas or electric engineering ( 220 v power engineering and 380 v power engineering) 。

5。 Consider traffic size, choosing the appropriate type of machinery and equipment.

6。 Head of different level, single pump or pump, high or low speed pump ( ) Efficiency is lower than that of single water pump, multi-stage pump. Single pump and multistage pump can be used in the same conditions, should choose single pump.

in other words, when we choose the dry vacuum water pump, not only to choose the right model, and the model is also very important. The model can according to the equipment to determine some of the parameters, the specific reference to the above, in order to choose a more suitable equipment to improve production efficiency.
