Umgomo wokusebenza:
Amaphampu e-diaphragm aqhutshwa umoya ocindezelweyo. I-valve yokusabalalisa umoya oqondisayo kanye ne-valve yomhlahlandlela, ebizwa ngokuthi: igumbi lomoya, ahlelwe engxenyeni emaphakathi yepompo. I-medium igeleza ngamashubhu amabili ahlanganayo kanye negumbi elingaphandle le-diaphragm, elibizwa ngokuthi igumbi eliphakathi. Ngokuvamile ama-valve okuhlola (ibhola noma i-disc) ahlelwa phezulu noma phansi kwegumbi ngalinye le-diaphragm langaphandle noma abelane ngeshubhu lokuhlangana. Amakamelo amabili e-diaphragm angaphandle axhunywe ngamajoyinti okumunca nawokuphuma, futhi iphampu iyazisebenza yona. Ekusebenzeni, ama-valve okusabalalisa umoya alawula ngokushintshana ukucindezelwa kwe-diaphragm ngayinye. Ngemuva kokushaywa ngakunye, i-valve izoshintsha ngokuzenzakalelayo indawo, ukuze umoya ushintshelwe kwelinye igumbi le-diaphragm, ukuze izinhlangothi ezimbili zegumbi le-diaphragm zenze okunye ukumunca kanye nokushaywa kwengcindezi, i-diaphragm ngokuhambisana ukuhamba endleleni. , i-valve yomoya ayikho isidingo sikawoyela wokugcoba uwoyela, lena imodi yokusebenza ekhethwayo; Umoya ohlanzekile, owomile ungathuthukisa ukusebenza kwepompo.
I-valve yomoya
I-valve yokuhlola ivula futhi ivale njengoba i-medium idlula epompo. Lokhu kuvumela igumbi ngalinye le-diaphragm langaphandle ukuthi ligcwaliswe futhi likhishwe ngokushintshana. I-valve yokuhlola iphendula umehluko wengcindezi. Ama-valve okuhlola amabhola angakwazi ukuphatha imidiya equkethe izinhlayiya ezincane, kuyilapho ama-valve okuhlola idiski akwazi ukuphatha imidiya equkethe izinhlayiya ezithambile eziseduze nobubanzi bepayipi. Lapho i-valve yokusabalalisa umoya yenza umoya ocindezelwe ungene egumbini le-diaphragm elingakwesobunxele, i-diaphragm iyacindezelwa, bese kwakheka ukushaywa kwe-pressure feed. I-medium emnyangweni we-pressure feed iphoqeleka ukuthi ishiye i-diaphragm yangaphandle ye-diaphragm, i-valve yokuhlola kanye ne-confluence tube, bese igeleza iphuma endaweni yepompo. Indawo yokuphuma ingaba phezulu, phansi, noma eceleni. Lapho igumbi le-diaphragm elingakwesobunxele liphushelwa ngaphandle ngaphansi kwengcindezi, induku yokuxhuma i-diaphragm ihudulela ngaphakathi i-diaphragm yesokudla ingene phakathi i-valve yokuhlola ehoxisiwe ukuze igcwalise uketshezi. Ngemuva kokuthi lesi senzo sokujikeleza sesiqediwe, i-valve yokusabalalisa umoya izoshintsha ngokuzenzakalelayo indawo yayo, ukuze umoya ushintshelwe kwelinye igumbi le-diaphragm, futhi isenzo esingenhla sokujikeleza sizophindwa ngokuphambene, okungukuthi, amagumbi e-diaphragm ezinhlangothini zombili azokwenza. ngakho-ke nikeza ingcindezi eshintshanayo kanye nesenzo sokumunca uketshezi.
Ukufakwa nokuqalisa
Ipompo ibekwe eduze komkhiqizo ngangokunokwenzeka, ukuze umugqa wokudonsa ube mfushane, inani lezingxenye zokumisa liyancipha, unganciphisi ukucaciswa kwepayipi.
Ukuze unwebe impilo ye-diaphragm, gcina iphampu iseduze noketshezi olumpontshwayo ngangokunokwenzeka, futhi ufake idivayisi yokulungisa ingcindezi ehamba kancane ukuze unwebe impilo ye-diaphragm lapho ukucindezela kokungena kudlula ikholomu engu-10 ft (3 m).
Uma ipayipi eliqinile lifakiwe, sebenzisa uxhumano olufushane lwepayipi phakathi kwepompo nepayipi. Amapayipi anganciphisa ukudlidliza nokuhlanekezela epayipini, futhi kunconywa ukuqinisa umfutho ukuze kuqhutshekwe nokunciphisa ama-pulses oketshezini.
Ukunikezwa kwegesi
Ingcindezi yokuhlinzeka ngegesi ngeke idlule ku-125PSI (8.6BAR) kumaphampu ensimbi kanye no-100PSI (6.9BAR) wamaphampu epulasitiki. Xhuma i-pump air inlet emthonjeni womoya onamandla owanele nokucindezela ukuze uhlangabezane nezidingo zokuklama. Uma umugqa wokuhlinzeka ngegesi uyipayipi eliqinile, xhuma ipayipi elifushane phakathi kwepompo nepayipi ukuze unciphise ukuhlanekezela. Ngaphezu kwesivalo sokungenisa umoya, isisindo sepayipi lokungenisa umoya nesihlungi esilawula ukucindezela kufanele futhi kusekelwe ngandlela thize. Uma ipayipi lingasekelwa, lingalimaza iphampu. I-valve elawula ukucindezela kufanele ifakwe ukuze kuqinisekiswe ukuthi ukucindezela kokuhlinzeka akudluli ububanzi obushiwo.
Imiyalelo Ngaphambi Kokusebenza
Ngaphambi kokuthi iphampu isebenze, hlola zonke izinto ezimisiwe ukuze uvimbele ukuxega, qinisa indawo evulekile ukuze ugweme ukuvuza, futhi ulungise ngendlela echazwe ekhadini elixhunywe nepompo.
Faka futhi uqale
Uma uqala, vula i-valve yomoya mayelana nokuphenduka okungu-1/2 kuya ku-3/4. Ngemuva kokuthi iphampu iqale, vula i-valve yomoya ukwandisa ukugeleza komoya ukuze ufinyelele ukugeleza okudingekayo.
qeda
Uma i-diaphragm iphukile, uketshezi olukhishiwe noma igesi izongena endaweni yomoya yepompo futhi ikhishelwe emkhathini. Lapho kukhishwa izinto eziyingozi noma ezinobuthi, kudingeka zihanjiswe ngamapayipi endaweni efanele ukuze zilahlwe ngendlela ephephile.
Uma iphampu icwiliswa ekusebenzeni kwe-liquid, igesi kufanele ikhishwe endaweni ewuketshezi, futhi ipayipi yokukhipha akufanele ibe ngaphansi kuka-1 "(2.45CM). Ukunciphisa ubukhulu bepayipi yokukhipha kunciphisa ukugeleza kwegesi futhi kunciphisa ukusetshenziswa kwepompo. Lapho izinga lezinto ezibonakalayo liphakeme kunepompo, i-outlet kufanele ibe endaweni ephakeme ukuvimbela i-siphon phenomenon.
Ezingeni elithile lokushisa nomswakama, igesi ekhishiwe ingase ibe yiqhwa, futhi ukusetshenziswa kwegesi yokomisa kungaqeda iningi lalezi zinkinga.
Ngemva kokusetshenziswa
Uma isetshenziselwa ukuthutha izinto eziphulukisiwe kalula, ukuze kuvinjelwe ukulimala kwepompo, ngemva kokusetshenziswa ngakunye ukuhlanza kahle iphampu. Ngemuva kokusetshenziswa, umkhiqizo oshiywe epompo uyoma noma unamathele epompo, okungabangela izinkinga ze-diaphragm ne-valve ngaphambi kokuqala okulandelayo. Emazingeni okushisa aqandayo, ipompo kufanele ikhishwe ngemuva kokusetshenziswa kunoma yikuphi.
Amanothi e-valve lubrication
I-valve yokusabalalisa umoya wephampu kanye ne-valve yomhlahlandlela iklanywe ngokuhambisana kungabikho mafutha okugcoba, lesi yisimo esihle sokusebenza. Kwezinye izimo, njengokuzilibazisa komuntu siqu noma ikhwalithi yomoya empofu kakhulu, umoya ocindezelweyo nawo ungagcotshwa, uhlelo lokuphakelwa komoya olucindezelwe lugcotshwe kahle, uhlelo lwephampu lomoya lungasebenza ngokugcobisa okufanele ludinga ukusetshenziswa kwe-lubricator yomugqa womoya, isethwe. ukupompa umoya njalo ngo-20SCFM ukuze ulethe ithonsi lamafutha ahlanzekile, Ingakwazi ukubuza ijika lokusebenza kwepompo elivulekile lobuningi.
