Uma kuqhathaniswa namathange amanzi endabuko kanye nemibhoshongo, ukunikezwa kwamanzi okuguquguquka okungaguquguquki okuguquguqukayo okuguquguqukayo kwamanzi kunobuhle bengcindezi ezinzile yokuphakelwa kwamanzi, izinga eliphezulu lokonga ugesi, ukwethembeka okuhle, futhi akukho ukungcoliswa kwemithombo yamanzi. Lesi sihloko sithatha isibonelo sesikhungo sokuphakelwa kwamanzi sisebenzisa isiguquli sefrikhwensi ukushayela amaphampu amathathu ukuze kuzuzwe ukunikezwa kwamanzi okucindezelwa njalo, futhi sinikeza isingeniso esiningiliziwe ochungechungeni lweziguquli zefrikhwensi ezizinikele zokuhlinzekwa kwamanzi kanye nokusetshenziswa kwazo ezinhlelweni zokuphakelwa kwamanzi ezinengcindezi eqhubekayo.
Isingeniso
Uhlelo lokuhlinzekwa kwamanzi luyingxenye ebalulekile futhi ebalulekile yokukhiqiza nempilo kazwelonke. Indlela evamile yokuhlinzeka ngamanzi ithatha indawo enkulu futhi ijwayele ukungcoliswa kwamanzi. Ububi obukhulu ukuthi umfutho wamanzi awukwazi ukugcinwa ungashintshi, okuholela ekutheni ezinye izinto zokusebenza zingasebenzi kahle. Ubuchwepheshe bokulawula isivinini esishintshashintshayo wubuchwepheshe bokulawula isivinini esingenasinyathelo se-AC motor. Esidingweni esiphuthumayo esikhulayo sokukhiqizwa kokuphepha kanye nekhwalithi yokuphakelwa kwamanzi, isixazululo sokuhlinzekwa kwamanzi ngomfutho oqhubekayo ngokusebenzisa ukulawulwa kwesivinini esishintshashintshayo kuya ngokuya kuqashelwa umphakathi.
Imishini yohlelo lokusebenza esizeni nezithombe
Isicelo esisesiza ngesesikhungo sokuphakela amanzi e-Shenzhen. Isiguquli esisodwa esingu-4kW siyadingeka ukuze kulawulwe amaphampu amanzi amathathu ukuze kuzuzwe ukuhlinzekwa kwamanzi ngomfutho njalo. Isiguquli sefrikhwensi siyadingeka ukuze silungise isivinini ngokuzenzakalelayo ngokuya ngesimo sangempela somfutho wamanzi futhi sinqume ukuthi ingabe amaphampu esibili nawesithathu adinga ukufakwa ekusebenzeni ukuze abambe iqhaza ekuhlinzekweni kwamanzi.
Ithiyori yokulawula
uhlelo lokulawula
Uhlelo lokuhlinzeka ngamanzi lufakwe izinzwa zokucindezela kuwebhusayithi esemthethweni yokuphakelwa kwamanzi, eziguqula isignali yokucindezela kwamanzi ibe isignali yohlobo lwamanje engu-4-20mA eyamukelekayo kusiguquli samaza. Uma uhlelo lusebenza, inzwa yokucindezela ithola ukucindezela kwamanzi ngesikhathi sangempela, futhi isiguquli semvamisa sithola isignali yokucindezela. Umehluko phakathi kwesignali yengcindezi yangempela kanye nesignali yengcindezi enikeziwe iyalungiswa ukuze yakhe isistimu ye-loop evaliwe yokucindezela. Isiguquli semvamisa silungisa isivinini senjini yepompo yamanzi ngokushintsha imvamisa ngokuphuma kwe-PID. Kodwa-ke, imikhawulo engaphezulu nephansi yesivinini sokusebenza sephampu yefrikhwensi eguquguqukayo ikhawulela ikhono lephampu eyodwa ukuze ibhekane nezikhathi zokusetshenziswa kwamanzi eziphakeme kakhulu nezingaphakeme kakhulu. Isiguquli samanzi esinengcindezi eqhubekayo ye-CT110 esakhiwe i-Shenzhen Dongli Sci Tech Innovation Technology Co., Ltd. sihlanganisa lesi simo esingenhla ukuze kwandiswe indlela enengqondo yokuhlinzeka ngamanzi. Ngokusebenzisa ama-relay amabili ayisizayo kanye nenani lamayunithi acushiwe, ilungisa ngokuzenzakalelayo inani eliphakeme kanye nokusetshenziswa kwamanzi esigodini ukuze kuqinisekiswe ingcindezi eqhubekayo kunethiwekhi yokuphakelwa kwamanzi futhi ihlangabezane nezidingo zamanzi zabasebenzisi.
I-CT110 Water Supply Logic Incazelo
Uchungechunge lwe-CT110 oluzinikele lwe-frequency converter lunomqondo owakhelwe ngaphakathi wokuphakelwa kwamanzi kanye nokulawula kwe-PID okulungiselelwe ukuqinisekisa ukucindezela kwamanzi okungaguquki. Ngesikhathi esifanayo, icubungula ngokuzenzakalelayo i-logic yokwengeza nokukhipha amaphampu, futhi ilungisa ngokuzenzakalelayo imvamisa ngesikhathi sokufakwa kwepompo kanye nezigaba zokususa ukuze kuqinisekiswe ukuthi umfutho wamanzi uhlala uzinzile futhi uyalawuleka phakathi nenqubo yokwengeza nokukhipha impompo.
I-logic yokuhlinzekwa kwamanzi ichazwa kanje
1. I-logic yokwengeza iphampu: Uma umfutho wamanzi uqhubeka nokuba ngaphansi kunomfutho obekiwe, isiguquli semvamisa siyasheshisa futhi sisebenze. Lapho isiguquli semvamisa sisheshisa endaweni yokufaka imvamisa yepompo (F13.01), uma umfutho wamanzi usengaphansi (setha iphesenti lokucindezela kwamanzi) (iphesenti lokubekezelela ingcindezi yephampu F13.02), kubhekwa ukuthi inombolo yamanje yamaphampu amanzi ayanele ukuwasebenzisa, futhi amaphampu amanzi amaningi adinga ukungezwa. Ngemuva kokuthi isikhathi sokulibaziseka sokwengezwa kwepompo sesifinyelelwe, i-relay eyisiza izosebenza, futhi iphampu izosebenza.
2. I-Pump axiliary logic: Iphampu esanda kufakwa iyiphampu yefrikhwensi yamandla, engase ibangele ukwanda okusheshayo komfutho wamanzi phakathi nenqubo yokumpompa. Ngakho-ke, iphampu yefrikhwensi eguquguqukayo izonciphisa ngokuzenzakalelayo imvamisa yayo phakathi nenqubo yokumpompa ukuze igweme ukucindezela kwamanzi okweqile. Isikhathi sokuncishiswa sephampu yefrikhwensi eguquguqukayo ngalesi sikhathi sinqunywa ngu-F08.01.
3. I-logic yokunciphisa iphampu: Uma umfutho wamanzi uqhubeka uba phezulu kunokucindezela okumisiwe, isiguquli semvamisa sisebenza ngesivinini esincishisiwe. Lapho isiguquli sefrequency sehla siye endaweni yokuvama ukuncishiswa kwephampu (F13.04), uma ingcindezi yamanzi isengaphansi (setha iphesenti lokucindezela kwamanzi) + (iphesenti lokubekezelela ingcindezi yokunciphisa iphampu F13.05), kubhekwa ukuthi inani lamanje lamaphampu amanzi liningi kakhulu futhi umsebenzi wepompo udinga ukuncishiswa. Ngemuva kokuthi isikhathi sokulibaziseka sokunciphisa iphampu sifinyelelwe, i-relay eyisizayo izosebenza, futhi iphampu izosebenza ngalesi sikhathi.
4. I-logic eyinsiza yokunciphisa iphampu: Ipompo esanda kuncishiswa iyiphampu yefrikhwensi yamandla, engase ibangele ukwehla ngokushesha kokucindezela kwamanzi phakathi nenqubo yokunciphisa iphampu. Ngakho-ke, phakathi nenqubo yokunciphisa iphampu, ipompo yemvamisa eguquguqukayo izokwandisa ngokuzenzakalelayo imvamisa ukuze igweme ukucindezela kwamanzi okuphansi lapho ingeza iphampu. Isikhathi sokusheshisa sephampu yefrikhwensi eguquguqukayo ngalesi sikhathi sinqunywa ngu-F08.00.
5. Indlela yokusebenza yokulala: Uma amaphampu asizayo emile futhi nomfutho wamanzi usephezulu, isiguquli semvamisa sizosebenza ngesivinini esincishisiwe. Uma imvamisa yesiguquli sefrikhwensi iphansi kunephuzu lokuvama kokunciphisa iphampu, isiguquli sefrikhwensi sizolala ngokuzenzakalelayo futhi ikhibhodi izobonisa isimo sokuthi "LALA".
6. Ingqondo yokulala nokuvuka: Esimeni sokulala sesiguquli sefrikhwensi, lapho umfutho wamanzi uphansi, imvamisa esethiwe ebalwa yi-PID iphakeme kunesethingi yefrikhwensi yokuvuka, futhi ingcindezi yamanje ingaphansi (setha iphesenti lokucindezela kwamanzi) - (iphesenti lokubekezelela ingcindezi yokuvuka F13.02), kucatshangwa ukuthi iphampu yokuguqula imvamisa idinga ukusebenza. Ngemuva kokulibaziseka kokuvuka, iphampu yokuguqula imvamisa izolala futhi ivuke.
7. Okubalulekile kokulawulwa kwepompo yamanzi: Okubalulekile kokubamba iqhaza kwepompo yamanzi ekusebenzeni yilokhu: iphampu ye-frequency eguquguqukayo>ipompo elisizayo 1>ipompo elisizayo 2. Okusho ukuthi, uma kudingekile ukwengeza iphampu, okokuqala wengeze iphampu yefrikhwensi eguquguqukayo, bese kuba i-axiliary pump 1, futhi ekugcineni i-axiliary pump 2; Uma kudingekile ukunciphisa iphampu, qala unciphise ipompo elisizayo 2, bese unciphisa ipompo elisizayo 1, futhi ekugcineni unciphise isiguquli semvamisa ukuze ulale nokulinda.
