Pneumatic booster pumps are divided into gas-liquid booster pumps (pneumatic liquid booster pumps) and gas booster pumps (pneumatic gas booster pumps);
The principle of a gas-liquid booster pump is to use the low air pressure of a large area piston to generate high-pressure liquid and gas of a small area piston. It relies on a low-pressure air source as the driving force to achieve left and right movement of the internal piston. Today, we will learn about the common sense of ordering pneumatic liquid booster pumps.
1. Working pressure and flow rate
The working pressure of all pumps and power units refers to the pump output pressure and flow rate when the driving air pressure is 0.48Mpa. If the large output pressure of the pump is greater than the required working pressure, safety measures should be considered. For high output pressure, please refer to&quo; in the product catalog; Approximate ratio table for driving air pressure and output hydraulic pressure under static conditions;. The selection of the power unit is consistent with the pump. For work flow, please refer to&quo; in the product catalog; Performance curve chart;.
2. Conveying liquid medium
The liquid medium conveyed by the pump is a key consideration in the selection of the pump. The material and hydraulic sealing ring of the hydraulic part are determined by the liquid medium conveyed. Pumps can be used with oil, water, and most liquid media. The main hydraulic sealing rings of the standard pump are neoprene and polyurethane, and the one-way valve seat is sealed with Teflon. Other sealing materials include fluorocarbon compounds and ethylenepropylene, which are mainly used for conveying special media. Please consult the factory or local distributor for sealing material selection.
3. Acceptable volume and weight
For certain applications, the overall dimensions and weight of pumps and power units also need to be carefully considered.
