Booster pump is divided into gas-liquid booster pump and gas booster pump. The principle is to use the low pressure of large area piston to generate high hydraulic pressure of small area piston. What should be paid attention to in self-service type selection of booster pump? Let's start with four questions.
1. What is the pressurized medium?
Liquid: such as clean water, hydraulic oil, aviation kerosene, emulsion, etc., gas-liquid booster pump shall be selected
Gas: air, nitrogen, oxygen, helium and other gases, then select the gas booster pump
Although the two types of pumps have the same principle, their structures are different, so they cannot be mixed.
2. What is the pressure before being pressurized by the pressurized medium?
For gas-liquid booster pump, the liquid source does not need pressure, and the medium can be sucked into the pump for pressurization depending on the self-priming capacity of the pump itself;
For the gas booster pump, the inlet pressure of the medium must be known, which determines the correct model selection. If the output pressure is more than 8MPa and the inlet pressure is less than 1.2MPa, the two-stage gas booster pump HGT series must be selected. For the HGS series and HGD series with a boost ratio of more than 10:1,
The intake air must have high pre pressure, such as nitrogen cylinder.
3. What is the temperature of the pressurized medium?
Booster pumps are generally not suitable for pressurization of high-temperature fluids.
4. If it is a pressure test, what is the volume of the product being pressurized?
If there is no specific data, you can choose relatively equal common volumes to describe, but you can't tell. Words such as small and very small are not helpful for selection because size is a relative concept.
The four questions about self selection of booster pump are summarized above. If you have any ideas or doubts, please come to our website http://www.sdjingtuo.com Consult!
