1. working pressure and flow
The operating pressure of the pneumatic turbocharging pump and the power unit refer to the pump output pressure and flow when the driving pressure is 0.6Mpa. If the maximum output pressure of the pump is greater than the required working pressure, the safety measures should be considered. For the maximum output pressure, please refer to the "static driving pressure and the output hydraulic approximate ratio table" in the product catalogue. The selection of the force unit is consistent with the pump. For working flow, refer to the "performance chart" in the catalog.
2. the pressure and flow of the driving gas
The driving pressure of the gas booster pump and the power unit in continuous operation is not more than 0.8Mpa. In the intermittent operation, the gas consumption of the air pump can be reached when the 0.8Mpa. is in the best state of performance. Please refer to the required gas flow meter.
3. transport liquid medium
The liquid medium for the gas booster pump is a part of the selection of the pneumatic booster pump. The material of the hydraulic part and the hydraulic seal are determined by the liquid medium. The pump can be used for oil, water and most liquid medium.
The main hydraulic seal of the standard pump is butadiene rubber and polyurethane, and the unidirectional seat adopts the teflon seal. Other sealing materials include fluorocarbon and ethyl propylene. These seals are mainly used for the special medium. Please consult the factory or local distributor for the selection of the sealing material.
4. the volume and weight of the gas booster pump are acceptable for some applications. The size and weight of the pneumatic turbocharging pump and power unit should also be considered. According to the requirements of the pressure and flow required by the customer, we can select the type selection of the pneumatic supercharging pump according to the following process.
Calculate the minimum pressure ratio of pump Ratio, or the pressure required by customers.
The minimum stroke volume Q of the pump is calculated.
According to the above calculation, choose the most suitable (pressure and flow approach, the cheapest - the price is more expensive under the same pressure level, the more expensive the pump is, the higher the pressure level is, the more expensive) the pump is, the more expensive the pump is, the more expensive the pump is.
In order to clear the expression and selection process of the gas booster pump, here is an example. For example, the oil pressure 150MPa is needed, the flow rate is only 30ml/min when the precharge is required. Accordingly, we first determine the minimum pressure ratio Ratio of the pump.
