Mapampu ambiri a vacuum amapanga phokoso lalikulu panthawi yogwira ntchito. Phokosoli limatha kubisa zoopsa zomwe zingachitike pazida, monga kuvala pang'ono ndi kulephera kwa makina, komanso zitha kusokoneza thanzi la ogwiritsa ntchito. Pofuna kuchepetsa phokosoli, nthawi zambiri amapaka mapampu a vacuumzoletsa mawu. Ngakhale mapampu ambiri a vacuum amatulutsa phokoso panthawi yogwira ntchito, si onse omwe amakhala ndi zotsekera, monga mapampu a vacuum osindikizidwa ndi mafuta.
Chifukwa chiyani mapampu a vacuum osindikizidwa ndi mafuta sakuikidwazoletsa mawu?
Izi zili choncho makamaka chifukwa cha mapangidwe awo ndi momwe amagwiritsira ntchito.
1. Makhalidwe Apangidwe Achilengedwe
Pampu zotsekera zotsekedwa ndi mafuta (monga mapampu a rotary vane) zimadalira filimu yamafuta kuti isindikize ndi kuthira mafuta. Phokoso lawo makamaka limachokera ku:
- Phokoso lamakina: kukangana pakati pa rotor ndi chipinda (pafupifupi 75-85 dB);
- Phokoso la mpweya: phokoso lotsika kwambiri lopangidwa ndi kuponderezedwa kwa mpweya ndi utsi;
- Phokoso lamafuta: Phokoso la viscous fluid lopangidwa ndi kufalikira kwamafuta.
Kugawa pafupipafupi kwa phokoso kumakhala kotsika komanso kwapakati. Ma silencer, omwe nthawi zambiri amapangidwira kuti azimveka phokoso loyenda kwambiri, sagwira ntchito. Chifukwa chake, mapampu a vacuum osindikizidwa ndi mafuta ndi oyenera kugwiritsidwa ntchito ndi mpanda wosamveka.
2. Zolepheretsa Kugwiritsa Ntchito
Utsi wa pampu zotsekera zotsekedwa ndi mafuta zimakhala ndi tinthu tating'onoting'ono ta mafuta. Ngati silencer yokhazikika yayikidwa, nkhungu yamafuta imatseka pang'onopang'ono pores za silencer (monga thovu lotulutsa mawu).
Ena anganene kuti mapampu a vacuum osindikizidwa ndi mafuta nthawi zambiri amakhala ndi zosefera zotulutsa mpweya, zomwe sizimasiya malo a silencer. Komabe, achoziziritsira mawuikhozanso kukhazikitsidwa kuseri kwa fyuluta yotulutsa mpweya. Kodi izi zikutanthauza kuti kuyika silencer kuseri kwa fyuluta yotulutsa mpweya kumathetsa kufunikira kwa nkhungu yamafuta yomwe imatseka zinthu zotsekereza? Komabe, kuyika uku kumakhalanso ndi vuto: kulowetsa fyuluta yamafuta ndi kukonza zinthu kumakhala kovuta kwambiri. Zosefera zotulutsa zokha zimathanso kuchepetsa phokoso, zomwe zimapangitsa kuti silencer yodzipereka ikhale yosafunikira.
Mosiyana ndi izi, mapampu owuma a screw vacuum alibe mafuta ndipo amatulutsa phokoso lambiri. Chotsekereza chingathandize kuchepetsa phokoso, kuteteza thanzi lakuthupi ndi maganizo a ogwira ntchito. Zotsatira zake zimakhala zabwino kwambiri zikagwiritsidwa ntchito limodzi ndi mpanda wosamveka kapena phiri la vibration-damping.
