Mokhahlelo oa khatello

PMC 1/PMC 3: Li-valve li etselitsoe max. khatello ea ho sebetsa ea 28 bar g (406 psi g).

Lintlha tsa tekheniki

PMC 1 le PMC 3 li sebelisoa mehala ea khase e chesang. PMC 1 e laola bokhoni ka mokhoa oa ho feto-fetoha ho itšetlehile ka tšusumetso ea taolo ea valve ea sefofane ea CVC e hokahaneng. Bona lifeiga. 1, 5 le 6. Ha ho theoha khatello ea ps moleng oa pontšo, diaphragm, 110, e kenya pini ea khatello sebakeng sa pilot orifice, 108, e bulang. Sena se fella ka ho phahama ha khatello ho pholletsa le servopiston, 24, le PMC 1 e bula. Ha ho phahama khatello ea ps moleng oa matšoao PMC 1 ea koala. Ha hoa tlameha ho khoneha ho thibela mohala oa pontšo. PMC 3 e laola bokhoni ka ho feto-fetoha ha molumo ho latela tšusumetso ea taolo ea li-valve tsa sefofane tse hokahaneng. Bona lifeiga. 2 le 7 ho ea ho 12. Belofo ea sefofane sa CVC e tlameha ho kenngoa ho Sll kamehla. Ho latela hore na li-valve tsa sefofane sa EVM li kentsoe hokae, mesebetsi e meraro e latelang e ka fumanoa:

1. Plug A ho Sl, CVC ho Sll, EVM ho P: Ho laola matla a ho feto-fetoha ho kopantsoe le ho feta ha valve e bulehileng. Bona lifeiga. 7 le 8.
2. EVM ho Sl, CVC ho Sll, plug A + B ho P: Ho laola matla a ho laola ho kopantsoe le valve e koetsoeng. Bona lifeiga. 9 le 10.
3. EVM ka bobeli ba Sl le P, CVC ho Sll: Ho laola matla a ho laola ho kopantsoe le valve e bulehileng le valve e koetsoeng. Bona lifeiga. 11 le 12.

PMC 1/PMC 3 e na le likhokahanyo tse tharo bakeng sa li-valve tsa sefofane: tse peli ka letoto, tse tšoailoeng "SI" le "S II", 'me e le' ngoe e tsamaisana le tsena tse peli, e tšoailoeng "P", bona lifeiga. 1 le 2.

Mohlala oa moraloampLehlakore la li-valve tsa lifofane tse hokahaneng le PMC 1/PMC 3 li ka bonoa lipalong tsa 6, 8, 10, le 12.

Haeba ho hlokahala li-valve tse peli feela bakeng sa mosebetsi o hlokahalang, khokahanyo ea sefofane sa boraro e tlameha ho koaloa ka plug e se nang letho (sheba feiga 5 le 7). Plaka e se nang letho e fanoa le valve.

Lethathamo la taolo

Ho kenya

Flange e behiloeng bakeng sa PMC 1/PMC 3 e fanoa ka thoko. Sephahla se tlameha ho kenngoa ka motsu ka tataiso ea phallo le sekoahelo se ka holimo ho ea holimo (setšoantšo sa 14). Sekoahelo se ka holimo se ka fetoloa 4 × 90 ° mabapi le 'mele oa valve.
Li-gaskets tse tsamaeang le CVC li tlameha ho kengoa pele li kenngoa ho Sll. O-ring e tlameha ho tlotsoa ka oli ea sehatsetsing. Belofo e kenngoa ka tsela e pota-potileng pakeng tsa mahlakoreng a phahameng le a tlaase a khatello ea compressor ka ho phalla ho ea ka tsela ea motsu le sekoahelo se ka holimo se shebile holimo. Bona feiga. 13. Mohala oa lets'oao o hokahane le mohala o monyang pakeng tsa evaporator le compressor. Haeba ho sebelisoa evaporating regulator ea khatello, mohala oa lets'oao o hokahane lipakeng tsa regulator le compressor. Haeba e khethiloe ho kenya khase e chesang mothapong o monyang pakeng tsa mouoane le kompressor ho ka hlokahala ho sireletsa mocheso o feteletseng oa li-tubes ka ho kenya mokelikeli moleng oa ho hula, mohlala, ka mofuta oa TEAT oa valve ea thermostatic. Mofuta oa PMC o na le spindle, 60, bakeng sa ho buloa ka letsoho.

Tlhophiso

Ha sekoahelo sa tiiso, 105, se tlositsoe, molaoli o ka behoa. Ho fetola spindle ea ho seta, 112, ho ea ka nako ho tla tiisa nako ea selemo 'me molaoli o tla qala ho bula ka khatello e phahameng ea ho hula. Phetoho e le 'ngoe ~ 1.5 bar. The valve e etselitsoe ho mamella khatello e phahameng ea ka hare. Leha ho le joalo, tsamaiso ea liphaephe e lokela ho etsoa ho qoba maraba a metsi le ho fokotsa kotsi ea khatello ea hydraulic e bakoang ke ho atolosoa ha mocheso.
E tlameha ho netefatsoa hore valve e sirelelitsoe ho tloha khatellong ea nako e kang "hamore ea metsi" tsamaisong.

Ho kenngoa ha li-valve flanges

Ha tjheseletsa / soldering flanges ho tsamaiso liphaephe sebelisa thepa feela le mekhoa tjheseletsa / soldering e lumellana le thepa ea flange.

• Etsa bonnete ba hore liphaephe tseo valve / flange li kenngoeng ho tsona li ts'ehelitsoe ka mokhoa o nepahetseng 'me li tsamaellana le lisekoere le ho fihla likarolong tse kopanyang. Netefatsa hore kopano ea li-valve e phethetsoeng ha e na likhatello tsa mejaro e kantle.
• Etsa bonnete ba hore libaka tse amehileng ke mocheso (ka hare le ka ntle) le libaka tsa ho nyalana tsa manonyeletso a nang le gasketed ha li na lithōle le mafome 'me li boemong bo botle.
• Sebelisa feela li-gaskets tse ncha tse entsoeng ke Danfoss.
• Etsa bonnete ba hore liboutu li tiisitsoe ka mokhoa o lekaneng ka mokhoa o fapanyetsanang.
• Sebelisa feela liboutu tsa tšepe tsa pele tsa Danfoss tse fanoeng ka valve. Li-bolts tsa tšepe tse sa hloekang li fana ka tšireletso ea kutu 'me li netefatsa ts'ebetso e sireletsehileng ho pholletsa le mefuta e mengata ea ts'ebetso ea valve ha e kenngoa hantle.
  Tlhokomeliso: Liboutu tsa tšepe tse sa hloekang li na le chai e tlase hanyane ha li bapisoa le liboutu tsa tšepe ea khabone. Hlokomela hore u se ke ua tiisa liboutu ho feta tekano.
• Netefatsa hore li-flanges / li-valve li lekoa ka khatello e nepahetseng, ho lekoa ho lutla, ho ntšoa pele u lefisoa ka sehatsetsing ho latela ANSI /IIAR 5, EN378-2 kapa ISO 5149-2.

Li-valve tsa PMC 1 / PMC 3 ha lia lokela ho kenngoa lits'ebetsong moo karolo ea phallo ea valve e bulehileng moeeng. Lehlakore la phallo la valve le tlameha ho lula le hokahane le sistimi kapa le koaletsoe hantle, bakeng sa mohlalaample e nang le sejana se tjheselitsoeng.

Mebala le boitsebahatso
Li-valve tsa PMC 1/PMC 3 li na le ZincChromated fekthering. Haeba ho hlokahala tšireletso e eketsehileng ea kutu, li-valve li ka penta. Khethollo e nepahetseng ea valve e etsoa ka poleiti ea ID e sekoahelong se ka holimo. Sebaka se ka ntle sa ntlo ea li-valve se tlameha ho thibeloa khahlanong le kutu ka seaparo se loketseng se sireletsang ka mor'a ho kenya le ho kopanya. Tšireletso ea poleiti ea ID ha ho penta valve hape ho khothaletsoa.

Tlhokomeliso: Kamehla ela hloko spindle nakong ea ts'ebetso ea opener ea tataiso (sheba feiga.17)

1. Etsa bonnete ba hore C-clip (C) e behiloe holim'a spindle (B) 'me e ntse e tiile. C-clip e ncha e fumaneha ka har'a khiti ea tlhahlobo ea valve.
2. Ela hloko C-clip e fihlang nut e ka holimo ea tšoelesa ea ho paka ha u fetola kutu ea letsoho ho ea ka nako bakeng sa ho bula valve. Le ka mohla u se ke ua sebelisa torque e feteletseng 'me u khaotse ho reteleha ha C-clip e kopana le nate e ka holimo.
3. Ha o fetola spindle (B) ka tsela e khahlanong le oache, bakeng sa ho koala sekoahelo sa bukana, ho ea holimo, tiisa spindle ho ea ho 8 Nm (5.9 lb/ft) torque.
4. Khutlisa sekoahelo (A) 'me u se tiise ho ea ho torque ea 8 Nm (5.9 lb/ft).

Sebelisa feela likarolo tsa pele tsa Danfoss, ho kenyelletsa le litšoelesa tsa ho paka, li-O-rings le li-gaskets bakeng sa ho nchafatsa. Lisebelisoa tsa likarolo tse ncha li netefalitsoe bakeng sa sehatsetsi se loketseng.

Maemong a pelaelo, ka kopo ikopanye le Danfoss.
Danfoss ha a amohele boikarabello bakeng sa liphoso le litlolo. Danfoss Industrial Refrigeration e na le tokelo ea ho etsa liphetoho ho lihlahisoa le Litlhaloso ntle le tsebiso pele.

Sengoliloeng se latelang se sebetsa ho lihlahisoa tse thathamisitsoeng tsa UL PMC 1 le PMC 3 E sebetsa ho lihatsetsi tsohle tse tloaelehileng tse sa cheng, ho kenyeletsoa/ho sa kenyeletsoe (+) R717 le likhase tse sa cheng/mekelikeli tse itšetlehileng ka tšebelisano ea thepa e tiisang (++). Khatello ea moralo ha e na ho ba ka tlase ho boleng bo boletsoeng ho Sec. 9.2 ea ANSI/ASHRAE 15 bakeng sa sehatsetsi se sebelisoang tsamaisong. (+++).

Danfoss e ke ke ea amohela boikarabello bakeng sa liphoso tse ka bang teng libukeng tsa libuka, libukana le lintho tse ling tse hatisitsoeng. Danfoss e na le tokelo ea ho fetola lihlahisoa tsa eona ntle le tsebiso. Sena se sebetsa le ho lihlahisoa tse seng li ntse li le teng ka taelo ha feela liphetoho tse joalo li ka etsoa ntle le liphetoho tse nyenyane tse hlokahalang ho latela litlhaloso tse seng li lumellane.
Matšoao ohle a thepa ena ke thepa ea lik'hamphani tse amehang. Danfoss le mofuta oa logo ea Danfoss ke matšoao a khoebo a Danfoss A/S. Litokelo tsohle li sirelelitsoe.
