Nzira yekusarudza zvinhu zve mechanical seals

Kusarudza zvinhu zvechisimbiso chako kwakakosha sezvo ichaita basa pakuona mhando, hupenyu uye kushanda kwechikumbiro, uye kuderedza matambudziko mune ramangwana.

Kusarudzwa kwezvinhu zvinowanzoshandiswa zvema mechanical seals.

1. Mvura yakachena, tembiricha yakajairika. Mhete yekufambisa: 9Cr18, 1Cr13, inotarisana necobalt chromium tungsten, simbi yakakandwa; Static mhete: resin impregnated graphite, bronze, phenolic plastiki.

2. Mvura yerwizi (ine sediment), tembiricha yakajairika. Dynamic mhete: tungsten carbide;

Stationary mhete: tungsten carbide.

3. Mvura yegungwa, tembiricha yakajairika Kufamba mhete: tungsten carbide, 1Cr13 yakatarisana necobalt chromium tungsten, simbi yakakandwa; Static mhete: resin-impregnated graphite, tungsten carbide, cermet.

4. Superheated mvura 100 degrees. Mhete yekufambisa: tungsten carbide, 1Cr13, cobalt chromium tungsten pakatarisana, simbi yakakandwa; Static mhete: resin-impregnated graphite, tungsten carbide, cermet.

5. peturu, mafuta ekuzora, mahydrocarbon emvura, tembiricha yakajairika. Mhete yekufambisa: tungsten carbide, 1Cr13, cobalt chromium tungsten pakatarisana, simbi yakakandwa; Static mhete: yakamisikidzwa neresin kana tin-antimony alloy graphite, phenolic plastiki.

6. peturu, mafuta ekuzora, liquid hydrocarbon, 100 madhigirii kufamba mhete: tungsten carbide, 1Cr13 pakatarisana cobalt chromium tungsten; Static mhete: bhuronzi yakadzikwa kana resin graphite.

7. Gasoline, mafuta ekuzora, liquid hydrocarbons, ine zvidimbu. Dynamic mhete: tungsten carbide; Stationary mhete: tungsten carbide.

Mhando uye mashandisirwo emidziyo yekuisa chisimbiso Zvinhu zvekuisa chisimbiso zvinofanirwa kusangana nezvinodiwa zvekuvhara basa. Nekuda kwema media akasiyana kuti avharwe uye akasiyana mamiriro ekushanda emidziyo, yekuisa chisimbiso zvinhu zvinodiwa kuti ive nekuchinjika kwakasiyana. Zvinodiwa zvekuvharisa zvinhu zvinowanzo:

1. Izvo zvinhu zvine density yakanaka uye hazvisi nyore kuburitsa midhiya.

2. Iva nesimba rakakodzera remagetsi uye kuoma.

3. Good compressibility uye kusimba, duku deformation zvachose.

4. Haina kupfava kana kuora pakupisa kwakanyanya, haina kuoma kana kuputika pakudzika kwakadzika.

5. Iine hutano hwakanaka hwekuora uye inogona kushanda kwenguva yakareba muasidhi, alkali, mafuta uye mamwe ma media. Huwandu hwayo uye kuomarara shanduko idiki, uye haina kunamatira kune simbi pamusoro.

6. Diki friction coefficient uye yakanaka kupfeka kusagadzikana.

7. Iine kushanduka kwekubatanidza nechokuisa chisimbiso.

8. Kuramba kukwegura kwakanaka uye kunogara kwenguva refu.

9. Zviri nyore kugadzirisa nekugadzira, zvakachipa uye zviri nyore kuwana zvinhu.

Rubber ndiyo inonyanya kushandiswa sealing material. Pamusoro perabha, zvimwe zvakakodzera zvekuisa chisimbiso zvinhu zvinosanganisira graphite, polytetrafluoroethylene uye akasiyana sealants.
