概述
A piston compressor is the right machine when air is needed occasionally rather than continuously: a tyre bay, a maintenance workshop, a small site. It is cheap to buy and easy to repair anywhere.
The mistake to avoid is buying one for a job that runs all day. Piston machines need a duty cycle of roughly 60 – 70%, and running one flat out will wear it out inside two years. If your air demand is continuous, a small screw machine will cost less over its life.

机器是怎么造的
活塞在气缸里往复运动，这是最古老、也最直接的压缩空气方式。在小规格和间歇使用的场合，它至今仍是正确答案——这也是这类机器比所有关于它"该退休了"的预言活得更久的原因。
真正要紧的是负载率。活塞机必须停下来散热，通常要占百分之三十到四十的时间；让它连续运转，是毁掉它最快的办法。
单级机适合大约十 bar 以内的压力。再往上就要加第二级并在两级之间冷却，把排气温度压在阀片和活塞环能活下来的范围内。
- 单级与双级两种机型
- 双级机带级间中冷
- 按负载率定额，不是按连续运行
- 皮带传动或直联传动
- 带储气罐，排水阀已装好
- 购机成本低
- 在任何地方都容易维修
- 有喷油版本，也有无油版本
控制器做的事
最简单的机器上是一只压力开关加一个小时表，大一些的机器上是一块正经的控制面板。两者做的事是一样的：低压启动，高压停机。
要紧的设定是压力带。压力带太窄会让机器启动得太频繁，而在活塞机上，启动次数对电机的磨损比运行小时更大。
更大的机组会加上保养倒计时、故障记录和热保护，这三样在一台本就容易被忽视的机器上都值得有。
- 带设定压力带的压力开关控制
- 压力带放宽，以限制启动次数
- 每台机器都有小时表
- 较大机组配保养倒计时
- 电机热保护
- 可选自动排水阀
- 带面板的机型配故障记录
- 较大机组采用星三角启动
配件与保养套件
阀片、活塞环、空气滤芯和油。阀片是决定产气量的那个件，而一组疲劳的阀片是悄悄多耗电，而不是大声地坏掉。
皮带传动机器的皮带张紧度，是车间里最被忽视的一项。打滑的皮带把电变成了热和橡胶粉，而不是空气。
这些机器是被设计来维修的，不是用坏即换。每一个易损件都能买到，周期也是公开的。
- 按周期更换的阀片套件
- 活塞环与垫片套件
- 空气滤芯与油列入保养计划
- 每次保养都检查皮带张紧度
- 每一个易损件都能买到
- 周期公开
- 本地有库存
- 服务方案下固定价格

常见问题
When is a piston compressor the right choice?
When air is needed occasionally rather than continuously: a tyre bay, a maintenance workshop, a small site. It is cheap to buy and repairable anywhere.
What is the duty cycle and why does it matter?
A piston machine needs to rest 30–40% of the time to shed heat. Running one flat out is the single most common reason a piston compressor dies inside two years.
Can it reach higher pressures than a screw?
Yes, two-stage piston machines reach 15 to 30 bar directly, which a single screw stage cannot do: that is why they are still used for high-pressure duties.
How long should one last?
Used within its duty cycle, ten years or more. Used continuously, often less than two. Duty cycle decides it, not the brand.
Are there oil-free piston machines?
Yes: non-lubricated versions for dental, laboratory and light clean duties, where the volumes are small and continuous running is not required.
What maintenance does it need?
Valves, rings, gaskets and oil. All are simple parts available in every market we serve, which is a large part of the appeal.
Why does mine get so hot?
Usually because it is running above its duty cycle, or the intake filter and cooling fins are choked with dust. Both are cheap to fix and both destroy the machine if ignored.
Do I still need a dryer?
Yes, if the air matters. A piston compressor produces the same water as any other, and in this climate that water reaches your tools within days.
Is it worth replacing a piston with a small screw?
If it runs more than a couple of hours a day, yes. The screw costs more up front and less over its life because it is not being destroyed by the duty.
How noisy is it?
Often above 85 dB(A) for an open machine, which needs hearing protection or a separate room. Silenced and canopied versions are available where noise matters.
