我之前買左個氣泵，但睇說明書話一般連續工作20分鐘就好停機。

然后今日行walmart見到個20蚊美金ge氣缸，覺得如果個氣泵加左氣缸會更好的話，不妨買個試試。所以想問各位大大：

1. 氣缸連同氣泵一起工作時候是點樣的？是不是先開氣泵，等充滿sai個氣缸就停機，然后噴筆直接利用氣缸d氣噴？
2. 如果1的假設正確，直接用氣缸的時候。會不會出現氣壓吾平均的情況？我有regulator,water-trap, filter,氣壓計一體ge物體，是否可以控制氣壓不變？
3. 氣泵同氣缸spec上有沒有硬性對應的規定？個缸是2 gallon, max 125psi的，我個氣泵是max 50psi的，會不會要好耐先充夠氣？
4. 我個氣泵無autocut的功能，甘要點先知道幾時氣缸充夠氣停泵？

好多問題，勞煩sai各位大大啦。

我個氣泵spec系：

Model Maker Mini Air Compressor CP-101
Motor: 1/8 HP
Air Displacement: 0.9 CFM (25L/min)
Max PSI: 50

希望d信息能讓大大們更容易解答小弟的問題啦。

氣缸好似要有auto cut 先有用
氣泵打氣入氣缸再出去噴槍
當氣缸既氣壓去到某程度
氣泵就會停機
令個泵省電同有冷卻

no. 氣缸唔一定要auto cut...
氣缸有store氣同stabilize pressure 兩功用..

香港噴油d人多數用 "bar" 做 unit.. 1 bar 約14.5 psi..
你個compressor去到50psi 去到 3bar多d, ok夠用, 其本上2bar都算大氣壓了. 0.8bar~1.5bar.

regulator就係用o黎control pressure.. 當然如果係用氣快過個compressor
既 Air Displacement 好多連個tank都stabilize唔到, 就會有pressure drop.

甘如果我個氣泵無auto-cut,系吾系要睇實個氣壓計，一drop就開泵補氣啊？

我用在0.3mm的噴筆上，會不會出現用氣快過個compressor
既 Air Displacement既情況？

係呀...不過唔洗睇實既
首先, 你個tank本身要有自己既pressure gauge, 你個compressor可以去到50psi, 如果有tank, 個tank去到~35~45psi就好要閂compressor了,  因為冇乜可以去到max pressure既..
regulator上既pressure gauge show既係 output pressure而唔係tank pressure. 要由regulator上既pressure gauge知tank pressure就要放盡regulator, 即output pressure = tank pressure. 但冇人會咁check tank pressure, 所以唔洗睇實 除非tank 本身有pressure gauge了. 其本上25L, 1/8 HP 唔係大power加個2gallon唔係大既tank, 你好可能要開二分鐘噴一兩分鐘就要開compressor了. 你不如加一個順手既power switch, 一噴就開, 一唔噴得耐就閂
你個tank max pressure 125psi 但你個 compressor只係max 50psi 打個20% discount 即40psi.. pressure一定係由高去低, 即個tank都只可以去到40psi.. 問題係咁, tank max pressure 既一定要大過 compressor pressure, 唔係就係一個炸彈,所以用係你個compressor都冇問題了...

你好肯定個tank係for compressor而唔係for propane???

hehe sounds like propane tank for me. but you can buy a air tank at ebay 2gallon 1/4" NPT ports (air ride) . for 40$ . typically if you use any hobby type compressor you don't really need a tank because you cannot store higher pressure just like the above member mentioned. the tank primary is to reduce the pumps duty cycles to have it last longer and not always noisy.

the only point you want to add the tank into your system now is just to smooth out your output air but in my peronal opinion.... this is a waste. i rather use this money to buy a model?

非常之感谢上面各位大大对小弟的问题的热心解答，你地实在太好人啦！

我隐约记得个包装写for air compressor既，但吾肯定，呢个weekend去walmart睇清楚先。如果系for compressor，20蚊美金可以考虑下咯。

甘其实加左tank后d气流平滑左喷出来的效果ge差别明吾明显呢？

to me? no difference .... unless you are airbrushing with more than 1 brush at a time.

well 20 buck go ahead an try ~ if it doen't work out... "Refund" lol
