1.增压的是介质是什么？
What is the medium used for pressurization?
液体：如清水、液压油、航空煤油、乳化液等，则选择气液增压泵气体：空气、氮气、氧气、氦气等气体，则选择气体增压泵两类泵虽然原理相同，但其结构不同，所以不能混用。
For liquids such as clean water, hydraulic oil, aviation kerosene, emulsion, etc., choose a gas-liquid booster pump. For gases such as air, nitrogen, oxygen, helium, etc., choose a gas booster pump. Although the principle is the same, the two types of pumps have different structures, so they cannot be mixed.
2.被增压介质增压前的压力是多少？
2. What is the pressure before being pressurized by the pressurized medium?
对于气液增压泵，液源无需压力，依靠泵自身的自吸能力即可将介质吸入泵中进行增压；对于气体增压泵，必须知道介质的进气压力，这绝定的后面的正确选型，如果输出压力在8MPa以上，进气压力小于1.2MPa则需选用双级气体增压泵HGT 系列，对于HGS系列、HGD系列增压比10：1以上的，进气必须有较高的预压，如氮气瓶等。
For gas-liquid booster pumps, the liquid source does not require pressure and relies on the pump's self priming ability to suck the medium into the pump for pressurization; For gas booster pumps, it is necessary to know the inlet pressure of the medium, which is crucial for the correct selection. If the output pressure is above 8MPa and the inlet pressure is less than 1.2MPa, the two-stage gas booster pump HGT series needs to be selected. For HGS series and HGD series with a boost ratio of 10:1 or above, the inlet gas must have a high pre pressure, such as nitrogen gas cylinders.
3.被增压介质的温度是多少？
3. What is the temperature of the pressurized medium?
气动增压泵一般不适用于高温流体的增压。
Pneumatic booster pumps are generally not suitable for boosting high-temperature fluids.
4.如果是压力检测，被打压的产品容积是多少？
If it is a pressure test, what is the volume of the product being compressed?
如果没有具体数据，可以选择相对等的常见容积进行描述，但不可告知，不大、很小等词语，因大小是个相对概念，对选型没有任何帮助
If there is no specific data available, you can choose common volumes that are relatively equal for description, but do not inform. Words such as "not big" or "very small" are not helpful for selection as size is a relative concept
