Dhizaini uye basa rema mechanical seals zvakaoma, zvinosanganisira akati wandei ekutanga zvikamu. Iwo akagadzirwa nezviso zvechisimbiso, elastomers, zvisimbiso zvechipiri, uye hardware, imwe neimwe iine hunhu hwakasiyana uye zvinangwa.

Izvo zvikamu zvikuru zve mechanical seal zvinosanganisira:

1. Chiso Chinotenderera (Mhete Yekutanga):Ichi ndicho chikamu chemagetsi chisimbiso chinotenderera ne shaft. Inowanzo kuve nechiso chakaoma, chisingapfekeke chakagadzirwa nezvinhu zvakaita sekabhoni, ceramic, kana tungsten carbide.
2. Chiso Chakamira (Chigaro kana Chechipiri Mhete):Chiso chakamira chinoramba chakamira uye hachitenderere. Inowanzo gadzirwa nechinhu chakapfava chinozadzisa chiso chinotenderera, kugadzira chisimbiso chekubatanidza. Zvishandiso zvakajairika zvinosanganisira ceramic, silicon carbide, uye akasiyana elastomers.
3. Elastomers:Elastomeric components, senge O-mhete uye gaskets, anoshandiswa kupa inoshanduka uye yakachengeteka chisimbiso pakati peimba yakamira uye shaft inotenderera.
4. Sekondari Seiling Elements:Izvi zvinosanganisira yechipiri O-mhete, V-mhete, kana zvimwe zvisimbiso zvinhu zvinobatsira kudzivirira kunze kusvibisa kupinda munzvimbo yekuisa chisimbiso.
5. Metal Parts:Akasiyana siyana masimbi, senge simbi casing kana dhiraivha bhendi, bata mechanical chisimbiso pamwe chete uye chengetedza kune midziyo.

Mechanical chisimbiso chiso

• Chiso chinotenderera chisimbiso: Mhete yekutanga, kana chiso chinotenderera chisimbiso, inofamba pamwe chete nechikamu chemuchina unotenderera, kazhinji shaft. Iyi mhete inowanzogadzirwa kubva kune yakaoma, yakasimba zvinhu senge silicon carbide kana tungsten carbide. Dhizaini yemhete yekutanga inovimbisa kuti inogona kuchengetedza masimba ekushanda uye kukwesha kunogadzirwa panguva yekushanda kwemuchina pasina deformation kana kupfeka zvakanyanya.

• Stationary chisimbiso chiso: Kusiyana neringi yekutanga, mhete yekubatanidza inoramba yakamira. Yakagadzirwa kuti iite sealing pair ine primary ring. Kunyangwe yakamira, inogadzirwa kuti igadzirise kufamba kwemhete yekutanga uku ichichengetedza chisimbiso chakasimba. Mhete yekubatanidza inowanzogadzirwa kubva kune zvinhu zvakaita sekabhoni, ceramic, kana silicon carbide.

Elastomers (O-mhete kana mabhero)

Izvi zvinhu, kazhinji maO-mhete kana mabhero, anoshanda kupa elasticity inodiwa kuchengetedza chisimbiso pakati pechisimbiso chechisimbiso uye shaft yemuchina kana imba. Ivo vanogamuchira kushomeka kweshaft misalignment uye vibrations pasina kukanganisa kutendeseka kwechisimbiso. Sarudzo yemidziyo ye elastomer inoenderana nezvinhu zvakasiyana, zvinosanganisira tembiricha, kudzvanywa, uye chimiro chemvura yakavharwa.

Sekondari Zvisimbiso

Sekondari zvisimbiso zvikamu zvinopa static sealing nzvimbo mukati me mechanical seal assembly. Ivo vanosimudzira kuita kwechisimbiso uye kuvimbika, kunyanya mumamiriro ezvinhu ane simba.

Hardware

• Springs: Zvitubu zvinopa mutoro unodiwa kune zviso zvechisimbiso, kuve nechokwadi chekugara uchisangana pakati pavo kunyangwe pasi pemamiriro ekushanda akasiyana. Izvi zvinogara zvichisangana zvinovimbisa chisimbiso chakavimbika uye chinoshanda mukati mekushanda kwemuchina.

• Retainers: Vanochengeta vanobata zvakasiyana zvikamu zvechisimbiso pamwechete. Vanochengetedza kurongeka kwakarurama uye nzvimbo yegungano rechisimbiso, kuve nechokwadi chekushanda kwakakwana.

• Gland plates: Gland mahwendefa anoshandiswa kuisa chisimbiso kumashini. Vanotsigira chisimbiso chinobatanidza, vachichichengeta chakachengeteka.

• Seta screws: Set screws zvidiki, zvakarukwa zvinhu zvinoshandiswa kuchengetedza mechanical seal assembly kune shaft. Vanova nechokwadi chokuti chisimbiso chinochengetedza nzvimbo yacho panguva yekushanda, kudzivirira kukanganisa kunogona kukanganisa kushanda kwechisimbiso.

 

 

 

 

Mukupedzisa

Chimwe nechimwe chikamu chemuchina chisimbiso chinoita basa rakakosha mukusungwa kunoshanda kwemuchina weindasitiri. Nekunzwisisa basa uye kukosha kwezvikamu izvi, munhu anogona kuonga kuomarara uye kurongeka kunodiwa mukugadzira nekuchengetedza mashandiro emagetsi zvisimbiso.
