Izinto zokuhlola ama-screw compressors wesitoreji esibandayo

1.Izinto zokuhlola ama-screw compressors wesitoreji esibandayo

(1)Hlola ukuthi ingabe akhona yini izimpawu zokuguga ezingavamile endaweni engaphakathi yomzimba nangaphezulu kwevalvu yesilayidi, bese ukala usayizi nokundingiliza kwendawo engaphakathi ngegeji yokudayela yobubanzi obungaphakathi.

(2) Hlola ukuthi akhona yini amamaki okuguga ekugcineni kobuso bamarotha ayinhloko nashayelwa kanye nezihlalo zokudonsa nezokuqeda umoya.

(3) Hlola ukuguga kwe-diameter yangaphandle kanye nezinyo le-rotor eyinhloko neshayelwa, futhi ulinganise ububanzi bangaphandle be-rotor ngegeji yokudayela yobubanzi obungaphandle.

(4) Linganisa ububanzi be-shaft eyinhloko ye-rotor kanye nobubanzi bangaphakathi bembobo yokuthwala eyinhloko, futhi uhlole ukuguga kwe-bearing eyinhloko.

(5) Hlola ukuguga kwe-shaft seal.

(6)Hlola wonke “o” izindandatho nezithombo ukuze uthole ukuguqulwa nokulimala.

(7) Hlola isimo sawo wonke amasekhethi kawoyela angaphakathi e-compressor.

(8) Hlola ukuthi inkomba yamandla yonakele noma ivinjiwe.

(9) Hlola i-piston kawoyela ne-balance piston ukuthi igugile ngendlela engavamile.

(10) Hlola ukuthi ingabe umongo wokudlulisela noma i-diaphragm yokuhlanganisa yonakele yini.

2.Ukugcinwa nokwehluleka kwesiqandisi sesikulufu

A.I-alamu yokugeleza kwamanzi abandayo aphansi

Iswishi yokugeleza okuqondiswe emanzini abandayo ayivaliwe, hlola futhi ulungise iswishi yokugeleza.

Iphampu yamanzi abandayo ayivuliwe.

Ivalvu yokuvala yepayipi lamanzi abandayo ayivuliwe.
B.I-alamu yokucindezela kwamafutha

Ukuphelelwa uwoyela kanye ne-alamu yokushintsha izinga likawoyela, i-alamu yomfutho kawoyela, i-alamu yomehluko wengcindezi kawoyela.

Ukuze usebenze isikhathi eside ngaphansi kwezimo eziphansi zomthwalo, indlela engcono kakhulu ukugcina iyunithi isebenza ngomthwalo ogcwele.

Izinga lokushisa lamanzi okupholisa liphansi (ngaphansi kwama-degree angu-20), okwenza kube nzima ukugcina ukunikezwa kukawoyela ngokuhluka kwengcindezi.

C.I-alamu yokucindezela okuphansi

Inzwa yomfutho ophansi iyehluleka noma ayithinteki kahle, yihlole noma uyishintshe.

Ishaja yesiqandisi enganele noma ukuvuza kweyunithi, hlola kanye nokushaja.

Okomisa okokuhlunga okuvalekile, kuhlakaze futhi kuhlanzeke.

Lapho ukuvulwa kwe-valve yokwandisa kukuncane kakhulu, i-steping motor yonakaliswa noma inokuxhumana okungalungile, ihlole, ilungise noma ishintshe.

D.I-alamu yokucindezela kokukhipha okuphezulu

Uma amanzi okupholisa engavulwanga noma ukugeleza kunganele, ukugeleza kungandiswa;

Izinga lokushisa lokungena kwamanzi okupholisa liphezulu, hlola umphumela wombhoshongo wokupholisa;

Amapayipi ethusi ku-condenser angcolile kakhulu, futhi amapayipi ethusi kufanele ahlanzwe;

Kukhona igesi engacondensable kuyunithi, khipha noma vacuumize iyunithi;

Isiqandisi eseqile singabuyiswa ngenani elidingekayo lesiqandisi;

Ipuleti lokuhlukanisa ekamelweni lamanzi le-condenser liphakathi, lilungisa noma lishintsha i-gasket yegumbi lamanzi;

Inzwa yengcindezi ephezulu iyehluleka.Faka esikhundleni inzwa.

E.Iphutha lomehluko womfutho kawoyela

I-economizer noma inzwa yomfutho kawoyela iyehluleka, ihlole bese uyibuyisela esikhundleni.

Izihlungi zangaphakathi nezangaphandle zivalekile, buyisela isihlungi.

Ukuhluleka kwevalvu ye-solenoid yokunikezwa kukawoyela.Hlola ikhoyili, ivalvu yesolenoid, lungisa noma shintsha.

Iphampu kawoyela noma i-valve yendlela eyodwa yeqembu lepompo likawoyela inephutha, hlola bese uyishintsha.

F.Uma sibheka ukuthi inkokhiso yesiqandisi ayanele

kudinga ukunakwa!Ingilazi yokubona epayipini eliwuketshezi libonisa ukuthi ama-bubbles awanele ukwahlulela ukuntuleka kwesiqandisi;izinga lokushisa lomusi ogcwele akwanele ukwahlulela ukuntuleka kwesiqandisi;ingahlulelwa ngezindlela ezilandelayo:

Qinisekisa ukuthi iyunithi isebenza ngaphansi kwezimo zokulayisha ezingu-100%;

Qinisekisa ukuthi izinga lokushisa lokuphuma kwamanzi abandayo le-evaporator liphakathi kuka-4.5 no-7.5 degrees;

Qinisekisa ukuthi umehluko wezinga lokushisa phakathi kokungena kwamanzi abandayo nokuphuma kwe-evaporator uphakathi kuka-5 no-6 degrees;

Qinisekisa ukuthi umehluko wezinga lokushisa lokudlulisa ukushisa ku-evaporator uphakathi kuka-0.5 no-2 degrees;

Uma lezi zimo ezingenhla zingafinyelelwanga, futhi ukuvulwa kwe-valve yokwandisa i-elekthronikhi kukhulu kunama-60%, futhi ingilazi yokubona ibonisa ama-bubbles, lesi sihloko sivela ku-Refrigeration Encyclopedia, ngokusekelwe lapho kungahlulelwa khona ukuthi iyunithi ayinayo ifriji.Ungakhokhisi ngokweqile ngesiqandisi, njengoba lokhu kuzoholela ekucindezelweni okuphezulu kokukhipha, ukusetshenziswa kwamanzi okupholisa okwengeziwe, futhi ngokunokwenzeka umonakalo ku-compressor.

G.Engeza isiqandisi

Ukuze uqinisekise ukuthi isiqandisi esanele sengeziwe, kuyadingeka ukwenza iyunithi isebenze ngokuqhubekayo ngaphansi kwezimo zomthwalo we-100%, ukuze izinga lokushisa lokuphuma kwamanzi abandayo le-evaporator libe yi-5 ~ 8 degrees, futhi umehluko wokushisa phakathi kokungena. futhi amanzi okukhipha aphakathi kuka-5 ~ 6 degrees.Indlela yokwahlulela ingabhekisa kokulandelayo:

Ukuvulwa kwe-valve yokwandisa kuphakathi kuka-40% no-60%;

Umehluko wokushisa wokudlulisa ukushisa we-evaporator uphakathi kuka-0.5 no-2 degrees;

Qinisekisa ukuthi iyunithi isebenza ngaphansi kwezimo zokulayisha ezingu-100%;.

Engeza uketshezi nge-valve yokugcwalisa uketshezi phezulu kwe-evaporator noma i-engeli valve ngezansi;

Ngemuva kokuthi iyunithi igijima ngokuzinzile, bheka ukuvulwa kwe-valve yokwandisa kagesi;

Uma ukuvulwa kwe-valve yokwandisa i-electronic kungu-40 ~ 60%, futhi kukhona njalo ama-bubbles engilazini yokubuka, engeza isiqandisisi se-liquid;

H,ukupompa isiqandisi

kudinga ukunakwa!Ungasebenzisi i-compressor ukumpompa isiqandisi esivela ku-evaporator, ngoba uma ingcindezi yokudonsa ingaphansi kwe-1kg, ingalimaza i-compressor.Sebenzisa idivayisi yokumpompa efrijini ukumpompa isiqandisi.
(1) Faka esikhundleni isihlungi sikawoyela esakhelwe ngaphakathi

Lapho iyunithi isebenza amahora angama-500 okokuqala, isihlungi samafutha se-compressor kufanele sihlolwe.Ngemva kwamahora angu-2000 wokusebenza, lesi sihloko sivela ku-Refrigeration Encyclopedia, noma uma umehluko wengcindezi phakathi kwangaphambili nangemuva kwesihlungi sikawoyela utholakala udlula ibha engu-2.1, isihlungi sikawoyela kufanele sihlakazwe futhi sihlolwe.

(2) Uma izimo ezimbili ezilandelayo zenzeka, ukwehla kwengcindezi yesihlungi sikawoyela kufanele kubhekwe:

I-compressor iyavaleka ngenxa ye-alamu 'yomehluko omkhulu wengcindezi kawoyela kumjikelezo wokunikezwa kukawoyela';

I-Compressor iyacisha ngenxa ye-alamu ethi 'Iswishi yezinga likawoyela inqanyuliwe'.

J.Inqubo yokushintsha isihlungi sikawoyela

Vala, cisha isishintshi somoya esicindezelayo, vala i-engela yokulungisa isihlungi sikawoyela, xhuma ipayipi ngembobo yokulungisa isihlungi sikawoyela, khipha uwoyela esihlungini sikawoyela, vula ipulaki lesihlungi sikawoyela, bese ukhipha isihlungi samafutha esidala. , indandatho ethi 'O' emanzi ngamafutha, faka isihlungi esisha sikawoyela, faka ipulaki entsha, buyisela isihlungi samafutha asizayo (isihlungi samafutha sangaphandle), khipha isihlungi sikawoyela ngembobo yesevisi yesihlungi kanye Nokusiza umoya kusihlungi sikawoyela, vula insizakalo yokuhlunga uwoyela. i-valve.

K,inkinobho yezinga likawoyela inqanyuliwe

Uma iyunithi ihlaba i-alamu ngokuphindaphindiwe ngenxa yokuthi inkinobho yezinga likawoyela inqanyuliwe, kusho ukuthi uwoyela kusihlukanisi samafutha awanele futhi inani elikhulu lamafutha liku-evaporator.Uma inkinobho yezinga likawoyela ihlale inqanyuliwe, sebenzisa iphampu kawoyela ukwengeza amalitha angaphezu kwamabili kawoyela kusihlukanisi sikawoyela, ungawengezi uwoyela kunoma iyiphi enye indawo, qinisekisa ukuthi inkinobho yezinga likawoyela ivaliwe, qala kabusha iyunithi, bese ugijima. at 100% umthwalo okungenani ihora 1 ngaphansi kwezimo ezivamile.

L.Amafutha agijimayo

Izizathu zokusebenzisa uwoyela osebenzayo: izinga lokushisa eliphansi le-superheat degree liholela kumphumela ongemuhle wokuhlukaniswa kwamafutha, futhi izinga lokushisa eligcwele leyunithi liphansi kakhulu (ukushisa kwamanzi okupholisa kuphansi), okuholela ekuhlukeni komfutho ophansi kawoyela, okwenza kube nzima ukuhamba kukawoyela.Faka i-valve enezinhlangothi ezintathu epayipini lamanzi le-condenser, futhi ulungise imingcele ye-PID yesilawuli se-valve yezindlela ezintathu ngendlela efanele ukuze uvimbele isilawuli ukuthi singazuli.

Lapho amafutha amaningi angena ku-evaporator futhi exubana nesiqandisi, kuzokwenziwa inani elikhulu legwebu.Uhlelo lokulawula luzokwazi ukubona lesi simo bese lwenza impendulo efanele.Lapho igwebu kukhiqizwa, umehluko wokushisa wokudlulisa ukushisa ku-evaporator uzokwanda futhi ande.I-valve izovuleka kakhulu, ivumele i-refrigerant eyengeziwe ukuba ingene ku-evaporator, ikhulise izinga lesiqandisi, ukuze amafutha adonswe yi-compressor futhi abuyiselwe emafutheni.
