Pneumatic booster pump is a high-hydraulic booster pump that uses the low pressure of a large-area piston to generate a small-area piston. It is mainly divided into gas-liquid booster pumps, gas booster pumps, and air booster pumps according to the application; if used Performance distinction, then it should be divided into single-acting pneumatic booster pump and double-acting pneumatic booster pump, what are “single-acting” and “double-acting”?
What is the difference between “single-acting” and “double-acting” pneumatic booster pumps?
Single-acting pump: that is, only pressurize once in a stroke, and the pump body has only one pump head;
Double-acting pump: that is, pressurize twice in one stroke, and the pump body has two pump heads (each pump head has an inlet and outlet);
Therefore, under the same driving pressure, compared with the double-acting pumps DGD and DGGD, the boost pressure of the single-acting pumps such as DGA and DGG is equal, but the flow rate is only half of that of the double-acting pumps. The choice of single-acting pump or double-acting pump is usually the choice of flow rate and efficiency. Of course, the choice of installation size should also be considered.
