Chisimbiso chakapfava chevharuvhu yeshavishavi nechisimbiso chakaoma

1. Ndeupi musiyano mukuru uripo pakati pevharafu yeshavishavi yakapfavauye vharuvhu yeshavishavi yakasimba?

Chishandiso chemhete yekuvhara chakasiyana. Chishandiso chekuvhara chevharuvhu remashavishavi rakapfava chinonzi "chigaro chesimbi + mhete yekuvhara isiri yesimbi", uye zvinhu zvinowanzoshandiswa zvinosanganisira rabha (EPDM/NBR), polytetrafluoroethylene (PTFE), nezvimwewo, sezvakaratidzwa muMufananidzo 01; chishandiso chekuvhara chevharuvhu remashavishavi rakapfava chinonzi "simbi kubva kusimbi", uye chigaro chevharuvhu nepamusoro pekuvhara zvinowanzogadzirwa nesimbi isina ngura, simbi ye alloy kana carbide surfacing. Chekutanga chinovhara ne elastic deformation yezvinhu, nepo chekupedzisira chichishandisa machine chaiyo uye kumanikidzwa kwepakati kuti chivhare.

2. Ndeipi tembiricha inoshanda yeimwe neimwe?

Zvisimbiso zvakapfava zvinongogumira pazvinhu zvisiri zvesimbi: EPDM rabha yakakodzera -40℃ ~ 120℃, uye PTFE inogona kusvika -40℃ ~ 200℃. Hapana muganho wakadaro kune zvisimbiso zvakasimba. Mavharuvhu ebhururuve esimbi isina tsvina akajairika akakodzera -40℃ ~ 425℃, uye zvinhu zve alloy zvakakosha zvinogona kutomira tembiricha yepamusoro inodarika 600℃.

3. Ndeipi nzira yekuisa chisimbiso iri nani?

Chisimbiso chakapfava chiri nani uye chinogona kuita kuti pasave nekubuda ropa (ANSI Class VI). Kuomarara kwerabha/PTFE kunogona kuzadza kusaenzana kwesimbi ne microscopic pamusoro uye kuita kuti simbi ivharwe. Nekuda kwekubatana kwakasimba kwesimbi, zvinodiwa zvechisimbiso chakasimba zvinowanzova ANSI Class IV~V (kubuda ropa kushoma kunobvumirwa), iyo yakakodzera kune process media ine kutsungirira kwakati kuti kubuda ropa.

4. Chii chinosiyana pakati penguva yebasa nemari yekuchengetedza?

Zvisimbiso zvakasimba zvinogara kwenguva refu. Ringi rerabha/PTFE rinovhara zvinyoro nyoro rinowanzo pera nekukwegura nekuda kwekukukurwa kwenguva refu uye kuchinjana nguva nenguva. Ringi rekuvhara rinowanzo fanira kutsiviwa makore maviri kusvika mashanu ega ega. Mushure mekunge simbi inovhara yakasimba yasvutwa necarbide, haiparare nekukukurwa, uye ine hupenyu hwebasa hweanopfuura makore gumi. Yakakodzera kugadziriswa nguva nenguva kwemamiriro ekushanda. Kunyangwe mutengo wekutanga wakakwira, mutengo wekugadzirisa kwenguva refu wakaderera.

5. Kuchinjika kwenhau kwakasiyana sei?

Chisimbiso chakapfava hachigoni kubatwa nengura yakasimba/zvipenyu zvine ngura. Kunyangwe rabha nePTFE zvine kugadzikana kwakanaka kwemakemikari, kana chinhu chacho chiine zvidimbu zvakaoma (senge slurry, coal powder), zvidimbu zvinogona kukwenya zviri nyore pamusoro pechisimbiso chakapfava kana vharuvhu ikavhurwa uye yavharwa, zvichikonzera kubuda kwemvura. Zvisimbiso zvakasimba zvakakodzera mamiriro ekushanda akaomarara akadai seutsi hwekupisa kwakanyanya, zvigadzirwa zvemafuta, slurry dzine zvidimbu, uye magasi ane simba rakawanda.

6. Mhedziso

Musiyano mukuru uripo pakati pechisimbiso chakapfava nechisimbiso chakaoma chevharuvhu yeshavishaviiri muchinhu chinovhara: chisimbiso chakapfava (rabha/PTFE) chine kusimba kwakanaka, hachigoni kuburitsa mvura, uye chakakodzera nzvimbo yakachena patembiricha yemumba; chisimbiso chakasimba (simbi kubva kusimbi) hachipise kupisa kwakanyanya uye hachipfeki, uye chakakodzera mamiriro ekushanda akaomarara akadai seutsi nezvidimbu. Zvese zvine zvazvakanakira, uye sarudzo yacho inofanira kunge yakavakirwa pamamiriro ekushanda.Tianjin Tanggu Mvura-Chisimbiso Valve Co.,Ltdinonyanya kugadziramavharuvhu eshavishavi, mavharuvhu egedhi, mavharuvhu ekuongororanedzimwe mhando dzemavharuvhu.
