Life is the main factor restricting air valve and spring - loaded valves quality , the general long - term continuous operation of the compressors to life 80 hours ; for mobile , short - term or intermittent operation of compressors , may require slightly more 限制氣閥壽命的主要因素是閥片及彈簧質(zhì)量,一般對(duì)長期連續(xù)運(yùn)轉(zhuǎn)的壓縮機(jī),希望壽命達(dá)8000小時(shí)以上;對(duì)移動(dòng)式、短期或間歇運(yùn)轉(zhuǎn)的壓縮機(jī),要求可稍低些。
