機(jī)械密封彈簧如何進(jìn)行壓縮量測(cè)量？

分類：壓縮彈簧新聞發(fā)布時(shí)間：2023-02-27

機(jī)械密封彈簧進(jìn)行壓縮量測(cè)量方法

機(jī)械密封彈簧壓縮量測(cè)量直接用卡尺測(cè)就是，先測(cè)量在自由狀態(tài)下的彈簧伸縮量，再測(cè)量機(jī)封安裝到位后的量，一減就是壓縮量。

集裝式密封可以不用自己去定壓縮量，因?yàn)檎麄€(gè)密封裝好時(shí)已定好了，非集裝式密封要根據(jù)不同的泵的類型來(lái)測(cè)量。

單彈簧機(jī)械密封的壓縮量為50%-70%,大概密封壓死后放開3-5mm,多彈簧（碟形簧）的壓縮量為90%左右，即機(jī)械密封壓死后放開1.5-2.5mm即可。同時(shí)還要考慮密封面的寬窄，彈簧的力度，工作時(shí)受力狀態(tài)。

調(diào)節(jié)彈簧壓縮量是為了滿足彈簧比壓，而不是為壓縮量而壓縮量，不管它是單彈簧還是多彈簧。通常，機(jī)泵機(jī)械密封的彈簧比壓大致控制在1.3-2.8kgf/cm2左右。最佳取值多少要根據(jù)實(shí)際工況條件、摩擦副配對(duì)材質(zhì)、補(bǔ)償環(huán)輔助密封圈結(jié)構(gòu)型式和要與載貨系數(shù)K值相適應(yīng)等等。
