1. Sumo Pfupi
The balance block is a important part of beam pumping unit, basa rayo nderekuenzanisa pombi unit Musiyano wekuchinjanisa mutoro panguva yekukwira nekudzika kwekurohwa, nekuti musoro wembongoro unotakurauremu hwevhirit yekoramu yemvura inobata pachikamu chepiston uye huremu hwekoramu yekuyamwa mumvura, pamwe nekukwesha, inertia, kuzunguzika uye mimwe mitoro panguva yekukwira kumusoro kwechikamu chekupomba.Kubhadhara simba rakawanda: nekuda kwekukura kwetsvimbo yekuyamwisa panguva yekudonha, musoro wembongoro unongotakura simba rekukwevera pasi.Haisi chete mota haidi kubhadhara simba, asi inoshanda pamota.Nokuti mutoro wepamusoro uye wepasi shamhu yakasiyana zvikuru, motokari yakanyanya Zviri nyore kupisa kunze, zvichiita kuti chikwata chepombi chisashande zvakanaka.Kuti ugadzirise matambudziko ari pamusoro apa, chigadziro chekuenzanisa chinofanira kushandiswa kuderedza mutsauko wemutoro pakati pepamusoro nepamusoro pekurohwa, kuitira kuti midziyo inogona kushanda zvakanaka.
Theuremu hwevhiriyakanyatsobatanidzwa kune crank ne "T" mhando mabhoti.Nekutenderera kwecrank, kutenderera kwedenderedzwa kunoitwa.Huremu hweuremu hwevhiriiri pakati pe500-1500kg.pa crank.Muchikamu chekupomba danda, chiyero che crank chinowanzo shandiswa kumichina inorema.Iyo yepasi gomba mutoro wakakura, uye pesvedzero yeakasiyana-siyana anochinjana mitoro inoita kuti bharanzi riite nyore kusunungura.Kana chivharo chechiyero chikaregedza uye chichitsvedza, chinokonzeresa kupomba Njodzi dzakadai sedzakakombama dzinobatanidza matanda, ma cranks abvaruka, uye mayuniti ekupomba hazvingokuvadzi zvakakomba midziyo yemusoro, asi kunyange kuisa pangozi kuchengetedzwa kwemunhu.Nokudaro, zvakakosha zvikuru kuongorora zvikonzero zvekusunungurwa kwebhanhire rekuvhara chikwata chepombi uye kutora matanho anoenderana kuderedza kuitika kwetsaona uye kuve nechokwadi chekushanda kwakajairika kwechigadzirwa chekupomba.
2. Chikonzero chekusununguka kwebhaudhi
Zvikonzero zvikuru zvekusunungurwa kwe "T" rudzilug nutskana muchina weoiri uchishanda ndiwo anotevera:
(1) Kusakwana preload Kana, muKushinga, kuitira kuti chokoreti ifambe zvakanaka, asi iyolug nutszvinoda pre-stressed.Matambudziko mukusunga shinda anodzvinyirirwa zvakanyanya.Shingairira kukunda muyedzo wekuzvivimba pashinda.Pane zvakawanda zvinosimudzira kana zvasvika pakurwa zvine hukasha kumisa makwikwi kuti asaiswa pamuyedzo.Hazvisi nyore kuomesa mabhoti, zvichiita kuti uremu huremu husununguke nyore nyore.
(2) Pane zvikanganiso mune kavirinutkukiya nzira: Kukiya kaviri nati inzira yakajairika yeshinda inodzivirira kusunungura mune zvazvino zvinoshanda.Iyo ine zvakanakira kugadzirisa zviri nyore, kugadzikana uye kuvimbika, uye nyore disassembly uye kusangana.Iyo inoshandiswa zvakanyanya mu petrochemical, kugadzirisa uye kugadzira maindasitiri, asi inogona chete kusangana neyakajairwa kusunungura zvinodiwa., Mhedzisiro yacho haina kunaka pasi pemitoro inodzokororwa inodzokororwa kwenguva yakareba, nekuti iyo inokwana pakati pezvibatanidza zvakarukwa ndeye clearance fit, uye shinda yemukati uye yekunze shinda zvishoma nezvishoma inokwana zvakasimba panguva ye pre-tightening process, uye shinda yekunze inoshanda. simba rekunze reAxial, iro rinoburitsa simba rinopokana rakatarisana negwara rekusimbisa, rinodzivirira bhaudhi kuti risasununguke, uye nokudaro rinoita basa rekusimbisa.Zvisinei, nekuda kwemukana pakati pebhaudhi uye nati, mutoro unogara uchichinja panguva yekushanda kwechigadzirwa, kuitira kuti simba rekutanga-kusimbisa pakati pemukati nekunze kwetambo richinje, uye tambo yakasungirirwa yakasununguka zvishoma.Kusununguka uku kucharamba kuchiunganidza nekufamba kwenguva kusvika bhaudhi radonha.
(3) Hunhu husina kukodzera hwekugadzira tambo Hunhu hwekugadzirisa hwezvikamu zvakasungwa zvine simba guru pane yekubatanidza peya.The common thread gap haina kuenzana.Kana shinda yeshinda yakakura, mukaha wakakodzera unowedzerwa, kuitira kuti tambo isati yasimba simba haigone kusvika kune tarisiro, uye zvakaoma kuburitsa friction yakakwana.Inomhanyisa kusunungura tambo pasi pemutoro unochinjana;kana iyo tambo clearance idiki, nzvimbo yekubatana yemukati nekunze tambo inova diki, uye pasi pekuita kwemutoro, chikamu chetambo chinotakura mutoro wakazara, kuderedza simba reshinda uye kukurumidza kutadza kwetambo yekubatanidza. .
(4) Hunhu hwekuisa hauite zvinodiwa.Paunenge uchiisa, nzvimbo yekubata inofanirwa kuve yakati sandara uye yakachena, uye iyo gap yakakura haifanirwe kudarika 0.04 mm.Zvikasadaro, planer kana faira rinofanira kushandiswa pakuyera.Kana mamiriro acho asingawanikwi, simbi yakatetepa inogona kushandiswa kuienzanisa.Kana paine kusvibiswa kwemafuta pakati penzvimbo mbiri dzekusangana, mabhaudhi echivharo chebhari haasungirwe zvakasimba, uye zvichave nyore kusunungura uye kutsvedza.
(5) Kufuridzirwa nezvimwe zvinhu, zvakadai sekudengenyeka kwemuviri apo chikwata chekupomba chinomira uye mabhureki, kushanduka kamwe kamwe kwekumanikidza kwepasi, nezvimwewo, zviri nyore kuita kuti nut yebhanhire rebhanhire risununguke.
3. Kuchengetedza Matanho
Kudzivirira kusunungurwa kwe threaded connection yemavhiri anorema, matanho anotevera anoenderana anofanirwa kutorwa kubva kune matatu maficha ekugadzira, kugadzira uye kuisa.
(1) Kuvandudza preload nzira Ndiko kuti, nzira yesayenzi inoshandiswa kushandisa torque inosimbisa inosangana nezvinodiwa kune mabhoti ekusimbisa kuti ave nechokwadi chokuti tambo yakasungirirwa inosangana nezvinodiwa pre-tightening simba.Zvinoenderana neasati aomesa torque zvinodiwa zvekubatanidza mabhaudhi, iyo yakanyanya kutenderwa pre-kusimbisa torque yeM42-M48 mabhoti inofanira kusvika 312-416KGM.Zvinoenderana neruzivo rwemumunda, zvakanaka kana chipanera chinobvongodza zvishoma.
(2) Wedzera matanho ekudzivirira-kusunungura Kuti kuve nechokwadi chekushanda kwakasimba kwenguva refu kwemichina, hazvina kukwana kushandisa simba rakakodzera rekugadzirisa, uye mamwe matanho anofanira kutorwa kudzivirira mabhoti kuti asasununguka.Akajairika anti-kusunungura matanho anosanganisira mana anotevera:
a.Friction kudzivirira kusunungura.Iyi nzira yakafanana neyo nzira yekuwedzera iyo pre-tightening simba.Nekuwedzera zvishongedzo, peya yekubatanidza inoburitsa dzvinyiriro inoramba iripo, nekudaro ichiwedzera simba rekupokana pakati petambo mbiri kudzivirira kuti dzisatenderedzane.Nzira dzakajairika dzinosanganisira: elastic washers, kaviri nuts, Self-locking nuts, etc. Iyi nzira yekudzivirira-inosunungura iri nyore kushanda uye iri nyore kuparadzanisa, asi iri nyore kusunungura pasi pemitoro yakareba inoshandura.
b.Mechanical anti-kusunungura.Iko kutenderera kwehukama pakati pema threaded pairs kunodzivirirwa nekuwedzera chivharo.Zvakadai sekushandiswa kwepini dzakapatsanurwa, waya dze serial uye mawashi ekumisa.Iyi nzira inoita kuti disassembly iite kusagadzikana, uye pini yekumisa inokuvara nyore.
c.Riveting punch kudzivirira kusunungura.Welding, kupisa-kunyunguduka uye mamwe maoperation anoitwa mushure mekutanga kurodha, izvo zvinoparadza chimiro cheshinda uye chinoita kuti tambo mbiri irasikirwe nehunhu hwekinematic pair uye kuva kubatana kusingaparadzanise.Kukanganisa kweiyi nzira ndeyokuti inogona kushandiswa kamwe chete uye mabhoti anofanira kuparadzwa zvachose pakuparadzanisa.
d.Structural anti-loosening.Uchishandisa tambo dzakapatsanurwa, tambo dzakanaka uye dzakadzokera kumashure dzinosanganiswa kuita bhaudhi rimwe, nokudaro kushandura chimiro chechipiri cheshinda.bhaudhi rimwechete rinogona kukwizwa kuita nati inotenderedza kana kuti nati inotenderedzwa.Munzira yakapesana, kuvharirana, ndiko kuti, nzira yeDown's thread anti-loosening.
Mumamiriro ezvinhu akaomarara ekushanda, nekuda kwesimba renguva refu rekuchinjana nguva dzakadai sekudengenyeka uye kukanganisa, zvose zvinosimbisa nati uye nati yekukiya inoregedzeka, asi iyo inosunga nati inoshandisa torque inopikisa kukiyi nati kana yadzoserwa kumashure. uye mberi., uye iyi torque ichawedzera kusimbisa lock nut kune inosimbisa nut, uye makungu maviri achavhara mumwe nemumwe kuitira kuti tambo yakasungirirwa irege kusunungurwa.Down's thread haidi kuwedzera zvinhu.Inongovimba chete nenzungu mbiri dzine mativi akapesana kuti dzipinzwe mubhaudhi rimwechete, uye nzungu mbiri dzakakiiwa pamwe chete.Kushanda kwacho kuri nyore, kwakachengeteka uye kwakavimbika, asi chimiro chetambo chinoumbwa pane chekunze chakaoma.Processing tekinoroji zvinodiwa zvakakwirira.Muchikamu chekupomba danda, nekuda kwesimba rekuchinjanisa mutoro uye kuzununguka, kusunungurwa kwemabhaudhi ekusimbisa emavhiri anoremayakajairika, uye kushandiswa kweDown's thread kudzivirira kusunungura kunogona kugadzirisa dambudziko iri zvakanaka.
