Uyifaka njani ivalve yokutywina iGasket

Iigaskets ziyinxalenye eqhelekileyo yesixhobo.

Igasket yefektri, ngaba uyifakile ngokuchanekileyo?

Ukuba ifakwe ngokungalunganga, i-gasket inokonakala ngexesha lokusebenza kwesixhobo kwaye ingaba yingozi.

Ziziphi izixhobo ezifunekayo ukufakela?

Lungiselela ezi zixhobo zilandelayo phambi kokufakwa:

Isitshixo setorque esilungelelanisiweyo, isitshixo sokuqinisa i-hydraulic, okanye ezinye izixhobo zokuqinisa;

Ibrashi yocingo lwentsimbi, ibrashi yobhedu ingcono;

Isigcina-ntloko

IiGoggles

Isithambiso

Ezinye izixhobo ezichazwe kwifektri, njl

Ukucoca kunye nokuqinisa i-fasteners kufuna iintlobo zezixhobo ezithile, ngaphezu koko, izixhobo zokufakela eziqhelekileyo kunye nokusebenza okukhuselekileyo kufuneka kulandelwe.

Amanyathelo ofakelo

1. Jonga kwaye ucoce:

Susa yonke into yangaphandle kunye ne-debris kwiindawo zokucinezela i-gasket, i-fasteners ehlukeneyo (iibholiti, ii-studs), amantongomane kunye ne-gaskets;

Khangela i-fasteners, i-nuts kunye ne-gaskets ye-burrs, ii-cracks kunye nezinye iziphene;

Jonga ukuba i-flange surface ijijekile, ingaba kukho imikrwelo ye-radial, ingaba kukho i-deep tool bump marks, okanye ezinye iziphene ezichaphazela ukuhlala okuchanekileyo kwe-gasket;

Ukuba imvelaphi enesiphene ifunyenwe, kufuneka itshintshwe ngexesha.Ukuba unawo nawaphi na amathandabuzo malunga nokuba uyitshintshe, unokuqhagamshelana nomenzi wetywina ngexesha.

2. Lungelelanisa iflenge:

Ukulungelelanisa ubuso beflange kunye nomngxuma webholithi;

Nayiphi na imeko engalunganga kufuneka ixelwe ngokukhawuleza.

3. Faka igasket:

Qinisekisa ukuba i-gasket idibana nobukhulu obuchaziweyo kunye nezinto ezichaziweyo;

Khangela i-gasket ukuqinisekisa ukuba akukho ziphene;

Faka ngokucophelela i-gasket phakathi kweeflange ezimbini;

Qinisekisa ukuba i-gasket iphakathi phakathi kweeflange;

Musa ukusebenzisa i-adhesive okanye i-anti-adhesive ngaphandle kokuba imiyalelo yokufakela i-gasket ibiza;lungelelanisa ubuso beflange ukuqinisekisa ukuba i-gasket ayigqojozwanga okanye ikrwelwe.

4. Thambisa indawo enoxinzelelo:

Kuphela zizithambiso ezichaziweyo okanye ezivunyiweyo ezivumelekileyo ukuba zisetyenziswe kwindawo yokuthambisa;

Faka i-lubricant eyaneleyo kwiindawo ezithwele yonke imisonto, amandongomane kunye neewasha;

Qinisekisa ukuba i-lubricant ayingcolisi i-flange okanye i-gasket surfaces.

5. Faka kwaye uqinise iibholithi:

Soloko usebenzisa isixhobo esifanelekileyo

Sebenzisa i-calibrated torque wrench, okanye esinye isixhobo sokuqinisa esilawula umsebenzi;

Qhagamshelana nesebe lobugcisa bomenzi wetywina malunga neemfuno kunye nemimiselo yetorque;

Xa uqinisa i-nut, landela "umgaqo we-cross-symmetrical";

Qinisa i-nut ngokwala manyathelo ama-5 alandelayo:

I-1: Ukuqiniswa kokuqala kwawo onke amantongomane kwenziwa ngesandla, kwaye amantongomane amakhulu angaqiniswa nge-wrench encinci ye-manual;

2: Qinisa i-nut nganye malunga ne-30% yetorque epheleleyo efunekayo;

3: Qinisa i-nut nganye malunga ne-60% yetorque epheleleyo efunekayo;

4: Qinisa nut nganye kwakhona usebenzisa "umnqamlezo symmetry umgaqo" ukufikelela 100% torque efunekayo yomthi wonke;

Phawula:Kwiiflange ezinkulu zobubanzi, la manyathelo angentla anokwenziwa ngamaxesha amaninzi

5: Qinisa onke amandongomane nganye-nganye kwicala lewotshi ubuncinane kube kanye kwitorque epheleleyo efunekayo.

6. Qinisa iibholithi kwakhona:

PHAWULA:Qhagamshelana nesebe lobugcisa bomenzi wetywina ukuze ufumane isikhokelo kunye neengcebiso malunga nokuqinisa kwakhona iibholithi;

Iigaskets ezingezizo i-asbestos kunye neegaskets ezineenxalenye zerabha eziye zasetyenziswa kumaqondo obushushu aphezulu kufuneka zingaqiniswa kwakhona (ngaphandle kokuba kuchazwe ngenye indlela);

Iifasteners ezifumene i-corrosion thermal cycles kufuneka ziphinde ziqiniswe;

Ukuqinisa kwakhona kufuneka kwenziwe kwiqondo lokushisa eliphantsi kunye noxinzelelo lwe-atmospheric.
