Mitundu yodziwika bwino ya mabearing a air compressor imagwiritsidwa ntchito

 

Chokometsera mpweya ndi chipangizo chomwe chimagwiritsidwa ntchito kupondereza mpweya. Kuti zipangizo zamakina zigwiritsidwe ntchito bwino, tiyenera kusankha mtundu woyenera kwambiri wa chokometsera malinga ndi zofunikira za zida zamakina komanso zosowa za ntchitoyo pogula.chogwirira mpweya chokometseras.

 

Pali mitundu isanu yodziwika bwino yachogwirira mpweya chokometseras:Mabearing a mpira wolumikizana ndi mzere umodzi, mabearing ozungulira ozungulira, mabearing ozungulira opendekera, mabearing a mpira wozama ndi mabearing a mpira wolumikizana ndi mfundo zinayi.

 

1.Mabeya a mpira wolumikizana ndi mzere umodzi

Amagwiritsidwa ntchito makamaka ngati ma bearing opondereza, okhazikika pa single kapena tandem (monga tandem, amatha kupirira katundu wopondereza kwambiri), oyenera nthawi yomwe pali katundu wozungulira komanso katundu wozungulira wopingasa mbali imodzi, pamapampu omwe amagwiritsidwa ntchito kunyamula ammonia media amagwiritsanso ntchito ma FP cages (mapampu), ma bearing okhala ndi suffix "B" yokhala ndi ngodya yolumikizira ya 40°, ma bearing otere amatha kupirira katundu wopondereza kwambiri (mapampu), ndipo ma bearing okhala ndi zisindikizo angagwiritsidwenso ntchito.

 

Ma bearing a mpira wolumikizana ndi mizere iwiri omwe apangidwa kumene a compressors a khola losindikizidwa okhala ndi geometry yokonzedwa bwino amagwiritsidwa ntchito makamaka ngati ma bearing oyendetsedwa, oyikidwa payekhapayekha kapena motsatizana (pomanga tandem, amatha kupirira katundu woyendetsedwa kwambiri). Oyenera katundu wozungulira komanso katundu woyendetsedwa kwambiri mbali imodzi, komanso mapampu a ammonia okhala ndi ma cage a FP. Mtundu wa "B" wokhala ndi ngodya yolumikizirana ya 40° ukhoza kupirira katundu woyendetsedwa kwambiri ndipo ndi woyeneranso kutseka ma cage atsopano okhala ndi geometry yoyendetsedwa bwino ya khola.

 

2.Mabeya ozungulira ozungulira a ma compressor a mpweya

 

Popeza ndi yokonzeka kupompa ndipo imatha kupirira kupsinjika kwakukulu, bearing iyi imathandizira zolakwika pamakina kapena kusakhazikika bwino kwa ma shaft, imatha kupirira katundu wa radial ndi axial, imadzilungamitsa yokha (mpaka 2°) pa katundu wolemera kwambiri, ndipo imasunga kukhazikika kwa magawo pa kutentha kogwira ntchito mpaka 200°C.

 

3.Ma bereji ozungulira okhala ndi tapered compressor a air

 

Ili ndi mphamvu yayikulu yonyamula katundu wa axial ndi radial, ndipo bearing ili ndi chitsogozo cholondola cha radial chifukwa cha malo ochepa a axial.

 

4. Mabeya a mpira wozama wa ma compressor a mpweya

 

Imagwiritsidwa ntchito makamaka ngati chonyamulira kumapeto, sichigwiritsidwa ntchito kawirikawiri ngati chonyamulira kumapeto, choyenera kugwiritsidwa ntchito mwachangu kwambiri, ndipo imathanso kuperekedwa ndi kapangidwe kotsekedwa.

 

Ma bearing a mpira wozama wothira mafuta ndi oyenera kugwiritsidwa ntchito ndi ma nx dm apamwamba, kutengera momwe amagwiritsidwira ntchito, ndipo mafuta okhalitsa nthawi yayitali nawonso ndi otheka, mwachitsanzo, palibe kudzozanso mafuta komwe kumafunika.

 

5. Chophimba cha mpweya cha compressor chokhala ndi mfundo zinayi

 

Imagwiritsidwa ntchito makamaka ngati chogwirira cha thrust mu ma compressor, chomwe sichigwiritsidwa ntchito kunyamula katundu wa radial, koma kunyamula katundu wamkulu wa axial mbali zonse ziwiri ndipo chimatha kunyamula katundu wocheperako wa radial. Popeza mphete yamkati ya chogwirira cha mpira cholumikizana ndi mfundo zinayi ndi yogawanika, kapangidwe kameneka kamathandiza kuti chigwirizane ndi zinthu zambiri zozungulira, motero kumawonjezera mphamvu yonyamula katundu wa radial ya chogwirira.

 

Chifukwa chakuti maberiyani ndi ogawanika mkati mwa mphete: khola lopangidwa ndi makina limawapangitsa kukhala oyenera kwambiri pazochitika zotumizira mwachangu kwambiri, chifukwa cha malo ochepa a axial omwe amalola kuti beriyaniyo iyendetsedwe bwino, komanso kapangidwe ka beriyani kakang'ono - palibe chifukwa chokhalira ndi beriyani yosiyana.

 

Kodi ndi zinthu ziti zomwe zimayambitsa kuwonongeka kwa bearing ya air compressor?

1. Kukhazikitsa kosayenera

2. mafuta osakwanira

3. Kuipitsa

4. kugwiritsa ntchito mopitirira muyeso

Malangizo: Sankhani mtundu woyenera wa bearing ndikusintha bearing yotopa nthawi zonse komanso munthawi yake.
