  雙吸泵更換機(jī)封時(shí)，那就請(qǐng)?jiān)谫?gòu)買(mǎi)機(jī)封前落實(shí)以下幾點(diǎn)再買(mǎi)。
1、機(jī)封的軸徑大小  
2、落實(shí)水泵的轉(zhuǎn)速，要使得機(jī)封動(dòng)環(huán)的轉(zhuǎn)速與水泵轉(zhuǎn)速相匹配
3、密封面平均圓周線速度。一般機(jī)封的圓周線速度≤30m/s；應(yīng)用彈簧靜止型機(jī)封圓周線速度≤100m/s；特殊可達(dá)≤150m/s
4、端面比壓  內(nèi)裝式機(jī)封一般取pc=0.3-0.6Mpa；外裝式，取pc=0.15-0.4Mpa。對(duì)于潤(rùn)滑性好的端面比壓可適當(dāng)增大，對(duì)黏度較大的液體應(yīng)增大端面比壓，可取pc=0.5-0.7Mpa；對(duì)于易揮發(fā)、潤(rùn)滑性較差的液體應(yīng)取較小的端面比壓，可取pc=0.3-0.45Mpa。
