Selection elements of high-pressure vortex air pump
source:Industry News release time:2021-09-03 Article author:Rosit Popular:Air band saw
When buying a high-pressure fan, the selection of the high-pressure vortex air pump is very important. In the selection, the communication is often not smooth due to technical terms, which will lead to many changes. Then, the selection elements of the vortex air pump are mainly What are there? In addition to the main characteristics of the fan, the ultimate pressure, the flow rate and the extraction rate, there are some terms related to the performance and parameters of the vortex fan selection:
1. Starting pressure. The pressure when the pump starts without damage and has a pumping effect.wall mounted home energy storage system
2. Pre-pressure. The outlet pressure of the vortex fan whose exhaust pressure is lower than 101325pa.
3. Maximum foreline pressure. Exceeding the foreline pressure that can damage the pump.
4. Maximum working pressure. The inlet pressure corresponding to the maximum flow. Under this pressure, the pump can work continuously without deterioration or damage.
5. Compression ratio. The ratio of the outlet pressure of the pump to the inlet pressure of a given gas.
6. Ho's coefficient. The ratio of the actual pumping rate on the area of the pumping channel to the theoretical pumping rate calculated by molecular effusion.
7. Pumping coefficient. The ratio of the actual pumping rate of the pump to the theoretical pumping rate calculated by the pump inlet area based on the molecular effusion.
8. Reflux rate. The mass flow rate of the pump liquid per unit area and unit time through the pump inlet in the opposite direction to the pumping direction when the pump is working under specified conditions.
9. Allowable amount of water vapor (unit: kg/h). Under normal environmental conditions, the mass flow rate of water vapor that the gas ballast pump can extract during continuous operation.
10. The maximum allowable water vapor inlet pressure. Under normal environmental conditions, the highest inlet pressure of water vapor that the gas ballast pump can extract during continuous operation.
