Paunenge uchiyedza masisitimu epombi matsva, mapaipi nemavharuvhu anoiswa kumiyedzo yekutanga: bvunzo mbiri dzekudonha, imwe 150% hydrostatic bvunzo uye imwe N2He (nitrogen, helium) bvunzo yekuvuza.Aya maedzo anovhara kwete chete maflange anobatanidza vharafu uye pombi, asiwo boneti nevharuvhu yemuviri inopindirana, pamwe neese plug/spool zvikamu mumuviri wevharuvhu.

Kuchengetedza kuti gomba mukati megedhi rakafanana kana bhora revhavha rinomanikidzwa zvakakwana panguva yekuedzwa, valve inofanira kunge iri munzvimbo ye50% yakazaruka, sezvinoratidzwa mumufananidzo 1. Kusvika ikozvino zvinhu zvose zvinoratidzika kunge zviri kushanda zvakanaka, asi zvinonyatsoita here? ita izvi kune anonyanya kushandiswa pasirose uye wedge gedhi mavharuvhu?Kana mavharuvhu ese ari pahafu-yakavhurika chinzvimbo sezvakaratidzwa muMufananidzo 2, kudzvanywa kuri mugomba kuchaita pavhavha shaft kurongedza.Spindle packing inowanzova graphite zvinhu.Pa150% yedhizaini yedhizaini, kana uchiyedzwa nemadiki mamorekuru magasi akadai sehelium, zvinowanzodiwa kuomesa mabhaudhi evhavha yevhavha yevhavha kuitira kuti uwane mhinduro dzakajairika.

Dambudziko nekushanda uku, zvisinei, nderekuti rinogona kudzvinyirira kurongedza, zvichiita kuti kuwedzerwa kunetseka kunodiwa kushanda valve.Sezvo kukwesha kunowedzera, ndozvinoitawo dhigirii rekushanda kupfeka pakurongedza.

Kana nzvimbo yevharuvhu isiri pachigaro chepamusoro chisimbiso, pane tsika yekumanikidza shaft yevharuvhu kuti irereke pakusunga bhoneti yekumanikidza.Kurereka kwevharuvhu shaft kunogona kuita kuti ikwenye chivharo chevhavha panguva yekushanda uye kukonzera mavanga.

Kana kusabatwa zvakanaka panguva yekuyedzwa kwekutanga kuchikonzera kudonha kubva pakurongedzerwa kweshaft, zvakajairika kuita kuti uwedzere kuomesa bonnet.Kuita izvi kunogona kukonzera kukanganisa kwakakomba kuvhavha yevhavha yevhavha uye / kana mabhoti egland.Mufananidzo 4 muenzaniso wechiitiko apo torque yakawandisa inoshandiswa kune gland nut / bhaudhi, zvichiita kuti chivharo chevhavha yekumanikidza kukotama uye kukanganisa.Kunyanya kunetseka pabhoneti yekumanikidza kunogonawo kukonzera kuti mabhoti ebhoneti abve.

Iyo nati yevhavha yevhavha yevhavha inozosunungurwa kuti ibvise kudzvanywa kwevhavha shaft kurongedza.Muedzo wekutanga mumamiriro ezvinhu aya unogona kuona kana pane dambudziko ne stem uye / kana bonnet seal.Kana kushanda kwechigaro chepamusoro chechisimbiso kwakashata, funga kutsiva valve.Mukupedzisa, chigaro chepamusoro chisimbiso chinofanira kunge chiri chisimbiso chesimbi-ku-metal.

Mushure mekuyedzwa kwekutanga, zvinodikanwa kuisa kwakakodzera compressive kushushikana kune hunde kurongedza uchiona kuti kurongedza hakuremekedze hunde.Nenzira iyi, kupera kwakanyanya kwevhavhavhavha inogona kudziviswa, uye hupenyu hwese hwebasa hwekurongedza hunogona kuchengetedzwa.Pane mapoinzi maviri akakosha kucherechedzwa: Chekutanga, iyo yakadzvanywa graphite kurongedza haidzoke kuhurumende isati yadzvanywa kunyangwe iyo yekunze kudzvanywa ikadonhedzwa, saka kuvuza kuchaitika mushure mekuburitsa kudzvanya kushushikana.Chechipiri, paunenge uchiomesa hunde kurongedza, iva nechokwadi chokuti nzvimbo yevhavha iri panzvimbo yechigaro chepamusoro chekuvhara.Zvikasadaro, kudzvanywa kwe graphite packing kunogona kunge kusina kuenzana, zvichiita kuti dzinde revharuvhu rive nekatsika kekurereka, izvo zvinozoita kuti pamusoro pechidzitiro chevharuvhu chikwekwe, uye vharafu inotakura inodonhedza zvakanyanya, uye vharafu yakadaro inofanirwa. kutsiviwa.
