Gas driven gas-liquid booster pump is a type of pump that uses compressed air as a power source to convert air pressure into hydraulic pressure for boosting liquid. Its main working principle is to pressurize the liquid by pushing the piston inside the pump with compressed air. Gas driven gas-liquid booster pumps are commonly used in applications that require high-pressure liquids, such as hydraulic equipment, testing systems, injection molding, etc. Before using gas-liquid, it is necessary to pre pressurize the gas-liquid booster pump to a certain extent to ensure its working effect.
The gas driven gas-liquid booster pump is driven by air. Compressed air enters the pneumatic part of the pump, pushing the piston to move. As the piston moves, the liquid in the hydraulic part is compressed, resulting in high pressure. The hydraulic chamber of a pump is usually connected to the working fluid, and when the piston moves, the fluid is compressed and discharged through the outlet. The pump controls the output pressure of the liquid by adjusting the air pressure. Due to the high compression ratio of gas driven booster pumps, small changes in air pressure can lead to significant changes in hydraulic pressure. Gas driven gas-liquid booster pumps are typically designed to automatically compensate for pressure drops. When the hydraulic pressure in the system drops, the pump will automatically start and re boost to maintain a stable output pressure.
The gas driven gas-liquid booster pump uses compressed air as a power source, so it does not require electricity and is suitable for environments that require explosion-proof or no power supply. It can convert low-pressure gas into high-pressure liquid with high efficiency and meet various high-pressure requirements. The internal structure of the pump is simple, highly reliable, and not easily damaged by high pressure. By adjusting the air pressure, the output hydraulic pressure can be easily controlled without the need for a complex control system.

The main reason why a gas-liquid booster pump needs to be pre pressurized during use is to ensure that the pump can provide stable output pressure during operation and avoid possible pressure fluctuations or insufficient flow. One important function of the preloading stroke is to stabilize the output pressure. After initial use or long-term disuse, hydraulic oil may have bubbles or incomplete filling of the hydraulic chamber. If high-pressure operation is carried out directly, these bubbles may cause pressure fluctuations, thereby affecting machining accuracy and equipment safety. The preloading stroke can stabilize the output pressure and ensure the normal operation of the equipment by eliminating bubbles and ensuring that the hydraulic chamber is filled with hydraulic oil. Pre pressing stroke helps reduce equipment wear and failure rates. By gradually increasing the pressure under low pressure, the various components of the gas-liquid booster cylinder can gradually adapt to the high-pressure working environment, thereby reducing the impact of instantaneous high pressure on seals and other key components. This not only helps to extend the lifespan of the equipment, but also reduces maintenance costs and downtime.
Smooth start-up: Pre increasing pressure can help the pump overcome initial resistance during start-up, thereby avoiding pump stalling or malfunction during start-up.
Ensure system stability: By pre increasing pressure, the liquid or gas inside the pump can be compressed to a certain level in advance, ensuring that the required working pressure can be quickly reached when the pump is officially working, thereby avoiding pressure instability in actual operation.
Reduce pressure fluctuations: Pre increasing pressure can effectively reduce pressure fluctuations that may occur during pump start-up and operation, ensuring the stability of output pressure and thereby improving the safety and reliability of the system.
Protection equipment: Some booster pump designs require a certain pre boost pressure to protect the mechanical components inside the pump, preventing wear or damage caused by low pressure or pressure fluctuations.
Therefore, when using a gas-liquid booster pump, pre pressurization is an important step to ensure the normal operation of the equipment and extend its service life.
