Momwe mungasankhire zida zosindikizira zamakina

Kusankha zinthu za chisindikizo chanu ndikofunikira chifukwa kudzakuthandizani kudziwa mtundu, moyo wautali komanso momwe ntchito ikugwiritsidwira ntchito, komanso kuchepetsa mavuto m'tsogolomu.

Kusankhidwa kwa zinthu zomwe zimagwiritsidwa ntchito kwambiri pazisindikizo zamakina.

1. Madzi oyera, kutentha kwabwino. mphete yosuntha: 9Cr18, 1Cr13, cobalt chromium tungsten, chitsulo chosungunuka; Static mphete: utomoni impregnated graphite, mkuwa, phenolic pulasitiki.

2. Madzi a mtsinje (okhala ndi matope), kutentha kwabwino. Mphete yamphamvu: tungsten carbide;

Mphete yoyima: tungsten carbide.

3. Madzi a m'nyanja, kutentha kwabwinobwino Kusuntha mphete: tungsten carbide, 1Cr13 poyang'ana cobalt chromium tungsten, chitsulo choponyedwa; mphete yosasunthika: graphite yokhala ndi resin-impregnated, tungsten carbide, cermet.

4. Madzi otentha kwambiri madigiri 100. mphete yosuntha: tungsten carbide, 1Cr13, cobalt chromium tungsten pamwamba, chitsulo choponyedwa; mphete yosasunthika: graphite yokhala ndi resin-impregnated, tungsten carbide, cermet.

5. Mafuta, mafuta opaka mafuta, ma hydrocarbon amadzimadzi, kutentha kwabwino. mphete yosuntha: tungsten carbide, 1Cr13, cobalt chromium tungsten pamwamba, chitsulo choponyedwa; Ring'i yokhazikika: yopangidwa ndi utomoni kapena tini-antimony alloy graphite, pulasitiki ya phenolic.

6. Mafuta, mafuta opaka mafuta, hydrocarbon yamadzimadzi, mphete yosuntha ya madigiri 100: tungsten carbide, 1Cr13 pamwamba pa cobalt chromium tungsten; mphete yosasunthika: mkuwa wopangidwa ndi utomoni kapena utomoni wa graphite.

7. Mafuta, mafuta opaka mafuta, ma hydrocarbons amadzimadzi, okhala ndi tinthu tating'onoting'ono. Mphete yamphamvu: tungsten carbide; Mphete yoyima: tungsten carbide.

Mitundu ndi ntchito za zipangizo zosindikizira Zida zosindikizira ziyenera kukwaniritsa zofunikira za ntchito yosindikiza. Chifukwa cha zofalitsa zosiyanasiyana kuti zisindikizidwe ndi zosiyana zogwirira ntchito za zipangizo, zipangizo zosindikizira zimafunika kuti zikhale ndi kusintha kosiyana. Zofunikira pazida zosindikizira ndizo:

1. Zomwe zili ndi kachulukidwe kabwino ndipo sizosavuta kutulutsa media.

2. Khalani ndi mphamvu zamakina zoyenera ndi kuuma.

3. Good compressibility ndi kupirira, yaing'ono mapindikidwe okhazikika.

4. Simafewetsa kapena kuwola pa kutentha kwakukulu, sikuuma kapena kusweka pa kutentha kochepa.

5. Ili ndi kukana bwino kwa dzimbiri ndipo imatha kugwira ntchito kwa nthawi yayitali mu acid, alkali, mafuta ndi media zina. Voliyumu yake ndi kuuma kwake kumasintha ndizochepa, ndipo sizimamatira pamwamba pazitsulo.

6. Coefficient yaing'ono yotsutsana ndi kukana kwabwino.

7. Imakhala ndi kusinthasintha kuphatikiza ndi kusindikiza pamwamba.

8. Good kukalamba kukana ndi cholimba.

9. Ndizosavuta kukonza ndi kupanga, zotsika mtengo komanso zosavuta kupeza zipangizo.

Rubber ndi chinthu chosindikizira chomwe chimagwiritsidwa ntchito kwambiri. Kuphatikiza pa mphira, zida zina zoyenera zosindikizira zimaphatikizapo graphite, polytetrafluoroethylene ndi zosindikizira zosiyanasiyana.
