1.增壓的是介質(zhì)是什么？
What is the medium used for pressurization?
液體：如清水、液壓油、航空煤油、乳化液等，則選擇氣液增壓泵氣體：空氣、氮氣、氧氣、氦氣等氣體，則選擇氣體增壓泵兩類泵雖然原理相同，但其結(jié)構(gòu)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.被增壓介質(zhì)增壓前的壓力是多少？
2. What is the pressure before being pressurized by the pressurized medium?
對于氣液增壓泵，液源無需壓力，依靠泵自身的自吸能力即可將介質(zhì)吸入泵中進行增壓；對于氣體增壓泵，必須知道介質(zhì)的進氣壓力，這絕定的后面的正確選型，如果輸出壓力在8MPa以上，進氣壓力小于1.2MPa則需選用雙級氣體增壓泵HGT 系列，對于HGS系列、HGD系列增壓比10：1以上的，進氣必須有較高的預(yù)壓，如氮氣瓶等。
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.被增壓介質(zhì)的溫度是多少？
3. What is the temperature of the pressurized medium?
氣動增壓泵一般不適用于高溫流體的增壓。
Pneumatic booster pumps are generally not suitable for boosting high-temperature fluids.
4.如果是壓力檢測，被打壓的產(chǎn)品容積是多少？
If it is a pressure test, what is the volume of the product being compressed?
如果沒有具體數(shù)據(jù)，可以選擇相對等的常見容積進行描述，但不可告知，不大、很小等詞語，因大小是個相對概念，對選型沒有任何幫助
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
