Mokhoa oa ho kenya valve ea ho tiisa Gasket

Li-gaskets ke karolo e tloaelehileng haholo ea lisebelisoa.

Factory gasket, na u e kentse ka nepo?

Haeba e kentsoe ka phoso, gasket e ka 'na ea senyeha nakong ea ts'ebetso ea lisebelisoa' me e ka ba ea e-ba kotsi.

Ke lisebelisoa life tse hlokahalang bakeng sa ho kenya?

Lokisetsa lisebelisoa tse latelang pele u kenya:

Wrench ea torque e lekantsoeng, wrench e tiisang haeteroliki, kapa lisebelisoa tse ling tse tiisang;

borashe ba tšepe ea tšepe, borashe ba koporo bo molemo;

Helmete

Li-Goggles

Setlolo

Lisebelisoa tse ling tse boletsoeng ke feme, joalo-joalo

Ho hloekisa le ho tiisa li-fasteners ho hloka lisebelisoa tse fapaneng tse khethehileng, ho phaella moo, lisebelisoa tse tloaelehileng tsa ho kenya le mokhoa o sireletsehileng o tlameha ho lateloa.

Mehato ea ho kenya

1. Hlahloba le ho hloekisa:

Tlosa lintho tsohle tse tsoang linaheng tse ling le lithōle ho tloha libakeng tsa khatiso tsa gasket, li-fasteners tse fapa-fapaneng (li-bolts, studs), linate le li-gaskets;

Sheba li-fasteners, linate le li-gaskets bakeng sa li-burrs, mapetsong le liphoso tse ling;

Sheba hore na sefahleho sa flange se sothehile, ho sa tsotellehe hore na ho na le likhahla tsa radial, hore na ho na le matšoao a tebileng a lisebelisoa, kapa liphoso tse ling tse amang setulo se nepahetseng sa gasket;

Haeba sekoli sa mantlha se fumanoa, se lokela ho nkeloa sebaka ka nako.Haeba u na le lipelaelo mabapi le hore na u ka e nkela sebaka, u ka ikopanya le moetsi oa tiiso ka nako.

2. Lokisetsa flange:

Lokisa sefahleho sa flange le lesoba la bolt;

Boemo leha e le bofe bo seng botle bo lokela ho tlalehoa hang-hang.

3. Kenya gasket:

Netefatsa hore gasket e kopana le boholo bo boletsoeng le thepa e boletsoeng;

Hlahloba gasket ho etsa bonnete ba hore ha ho na liphoso;

Ka hloko kenya gasket pakeng tsa flanges tse peli;

Netefatsa hore gasket e bohareng pakeng tsa flanges;

U se ke ua sebelisa sekhomaretsi kapa se-anti-adhesive ntle le haeba litaelo tsa ho kenya gasket li le bitsa;lokisa lifahleho tsa flange ho etsa bonnete ba hore gasket ha e phunngoe kapa ho ngolisoa.

4. Tlotsa sebaka se sithabetseng:

Ke lilubricant tse boletsoeng feela kapa tse lumelletsoeng tse lumelletsoeng ho sebelisoa bakeng sa sebaka se tsamaisang matla a ho tlotsa;

Sebelisa lubricant e lekaneng libakeng tse nang le likhoele tsohle, linate le li-washer;

Etsa bonnete ba hore setlolo ha se silafatse flange kapa bokaholimo ba gasket.

5. Kenya le ho tiisa liboutu:

Kamehla sebelisa sesebelisoa se nepahetseng

Sebelisa wrench ea torque e lekantsoeng, kapa sesebelisoa se seng sa ho tiisa se laolang mosebetsi;

Buisana le lefapha la tekheniki la moetsi oa tiiso mabapi le litlhoko le melaoana ea torque;

Ha u tiisa linate, latela "cross-symmetrical principle";

Tiisa linate ho latela mehato e 5 e latelang:

1: Ho tiisoa ha pele ha linate tsohle ho etsoa ka letsoho, 'me linate tse khōloanyane li ka tiisoa ka wrench e nyenyane ea matsoho;

2: Tiisa nate ka 'ngoe ho hoo e ka bang 30% ea torque eohle e hlokahalang;

3: Tiisa nate ka 'ngoe ho hoo e ka bang 60% ea torque eohle e hlokahalang;

4: Tiisa nate e 'ngoe hape u sebelisa "cross symmetry principle" ho fihlela 100% ea torque e hlokahalang ea lehong lohle;

Hlokomela:Bakeng sa li-flange tse kholo tsa bophara, mehato e ka holimo e ka etsoa ka makhetlo a mangata

5: Tiisa linate tsohle ka bonngoe ka tsela ea clockwise bonyane hang ho fihlela torque e hlokahalang.

6. Tiisa liboutu hape:

HLOKOMELA:Buisana le lefapha la botekgeniki la moetsi oa litiiso bakeng sa tataiso le keletso ea ho tiisa liboutu;

Li-gaskets tse se nang asbestos le li-gaskets tse nang le likarolo tsa rabara tse sebelisitsoeng mocheso o phahameng ha lia lokela ho tiisoa hape (ntle le haeba ho boletsoe ka tsela e 'ngoe);

Li-fasteners tse fumaneng lipotoloho tsa mocheso oa kutu li hloka ho tiisoa hape;

Ho tiisa hape ho lokela ho etsoa mochesong oa tikoloho le khatello ea sepakapaka.
