气液增压泵是一种的动力转换机械，主要应用于气液转换动力站中，其主要采用气油转换方法，由1-7bar压缩空气驱动，通过压缩空气将低压油变为高压油，从而提供高出力。由于气液转换动力站同时结合了气动和液压原理，具备传动速度快、出压力大、工作噪音小、性价比高等优点，是现代压力设备的换代产品。

The gas-liquid booster pump is a kind of power conversion machine, which is mainly used in the gas-liquid conversion power station. It is mainly driven by 1-7bar compressed air by using the gas oil conversion method. The compressed air changes low pressure oil into high pressure oil to provide high output. As the gas-liquid conversion power station combines the pneumatic and hydraulic principles at the same time, it has the advantages of fast transmission speed, large output pressure, low working noise, high cost performance, and is a replacement product of modern pressure equipment.

现有气液增压泵多为单头单作用增压泵或双头双作用增压泵，单头单作用增压泵只在气驱缸一侧设有高压增压腔体，且只在活塞杆向一侧运动时才会有高压液压油输出，吸油时不能供油，故增压泵流量相对较小；双头双作用增压泵在活塞杆两侧运动时，一侧吸油另一侧输出高压油，能提供连续的油源，然而其气驱缸长度增加，体积大而使用成本高。

Most of the existing gas-liquid booster pumps are single head single acting booster pumps or double head double acting booster pumps. The single head single acting booster pump is only equipped with a high-pressure booster chamber on one side of the gas drive cylinder, and only when the piston rod moves to one side can high-pressure hydraulic oil be output, and oil cannot be supplied during oil suction, so the flow of the booster pump is relatively small; When the double head double acting booster pump moves on both sides of the piston rod, one side absorbs oil and the other side outputs high-pressure oil, which can provide a continuous oil source. However, its gas drive cylinder has increased length, large volume and high use cost.

为解决现有单头单作用气液增压泵无法实现连续工作效率较低，而双头双作用气液增压泵相对成本高的问题，提高气液转换动力站性价比，为解决上述技术问题，本实用采用以下技术方案：

In order to solve the problem that the existing single head single acting gas-liquid booster pump cannot achieve low continuous working efficiency, while the double head double acting gas-liquid booster pump has high relative cost, and improve the cost-effectiveness of the gas-liquid conversion power station, in order to solve the above technical problems, the utility adopts the following technical solutions:
