增壓泵分為氣液增壓泵，
氣體增壓泵，原理是利用大面積活塞的低氣壓產(chǎn)生小面積活塞的高液壓。增壓泵自助選型應注意事項有哪些呢？先從四個(gè)問(wèn)題了解起來(lái)。
Booster pump is divided into gas-liquid booster pump and gas booster pump. The principle is to use the low pressure of large area piston to generate high hydraulic pressure of small area piston. What should be paid attention to in self-service type selection of booster pump? Let's start with four questions.
1.增壓的是介質(zhì)是什么?
1. What is the pressurized medium?
液體：如清水、液壓油、航空煤油、乳化液等，則選擇氣液增壓泵
Liquid: such as clean water, hydraulic oil, aviation kerosene, emulsion, etc., gas-liquid booster pump shall be selected
氣體：空氣、氮氣、氧氣、氦氣等氣體，則選擇氣體增壓泵
Gas: air, nitrogen, oxygen, helium and other gases, then select the gas booster pump
兩類(lèi)泵雖然原理相同，但其結構不同，所以不能混用。
Although the two types of pumps have the same principle, their structures are different, 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(wú)需壓力，依靠泵自身的自吸能力即可將介質(zhì)吸入泵中進(jìn)行增壓;
For gas-liquid booster pump, the liquid source does not need pressure, and the medium can be sucked into the pump for pressurization depending on the self-priming capacity of the pump itself;
對于氣體增壓泵，須知道介質(zhì)的進(jìn)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(jìn)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，
For the gas booster pump, the inlet pressure of the medium must be known, which determines the correct model selection. If the output pressure is more than 8MPa and the inlet pressure is less than 1.2MPa, the two-stage gas booster pump HGT series must be selected. For the HGS series and HGD series with a boost ratio of more than 10:1,
進(jìn)氣須有較高的預壓，如氮氣瓶等。
The intake air must have high pre pressure, such as nitrogen cylinder.
3.被增壓介質(zhì)的溫度是多少?
3. What is the temperature of the pressurized medium?
增壓泵一般不適用于高溫流體的增壓。
Booster pumps are generally not suitable for pressurization of high-temperature fluids.
4.如果是壓力檢測，被打壓的產(chǎn)品容積是多少?
4. If it is a pressure test, what is the volume of the product being pressurized?
如果沒(méi)有具體數據，可以選擇相對等的常見(jiàn)容積進(jìn)行描述，但不可告知，不大、很小等詞語(yǔ)，因大小是個(gè)相對概念，對選型沒(méi)有任何幫助。
If there is no specific data, you can choose relatively equal common volumes to describe, but you can't tell. Words such as small and very small are not helpful for selection because size is a relative concept.
