Vacuum pump is a kind of general-purpose machinery with a wide range of applications. It is very important to choose its type and model correctly. Due to the unreasonable selection, many Vacuum pumps are operating in an abnormal state, resulting in energy waste, increased maintenance costs, and even no normal use at all. Therefore, the selection needs to be carried out carefully, and the pros and cons of different schemes are repeatedly compared to ensure that they can operate normally. Let's follow the editor of Wholesale Rotary vane vacuum pump to see what its purchasing principles are!
One, meet the requirements
The selected Vacuum pump should meet the process design requirements.
2. Keep it simple
The simple structure is preferred. Because the simple structure is compared with the complex structure, the former has the advantages of high reliability, convenient maintenance, and low total cost during the life cycle.
1. When there is a measurement requirement, select the measurement type.
2. For small flow and high head, use vortex type, reciprocating pump.
3. When the flow rate (pressure) is not pulsating, the vortex pump is selected when the flow rate is high and the head is small.
4. For large flow and low head, choose axial flow or mixed flow.
5. When the medium has 75% air, the flow is small and the viscosity is less than 37.4mm2/s, the vortex vacuum pump is used.
6. When the medium viscosity is large (greater than 650~1000mm2/s), use the rotor and reciprocating.
The above is the editor of Wholesale Rotary vane vacuum pump introducing the purchase principles of Vacuum pump. I hope you can learn more.
