Uri kuisa tambo itsva yemvura wotora vharuvhu yePVC. Asi kana usingazive muganho wayo wekumanikidzwa, uri panjodzi yekuputika kukuru, mafashamo makuru, uye nguva yekushanda kwesystem inodhura.
Vharuvhu yebhora yePVC yeSchedule 40 inowanzo shandiswa pakubata 150 PSI (Mapaundi paSkweya Inch) pa73°F (23°C). Kumanikidzwa uku kunodzikira zvakanyanya sezvo tembiricha yemvura ichiwedzera, saka zvakakosha kutarisa zvinodiwa nemugadziri.
Nhamba iyoyo, 150 PSI, ndiyo mhinduro iri nyore. Asi mhinduro chaiyo yakaoma, uye kuinzwisisa ndiko kunokosha pakuvaka sisitimu yakachengeteka uye yakavimbika. Ndinowanzo kurukura izvi naBudi, maneja wekutenga muIndonesia. Anodzidzisa timu yake kubvunza vatengi kwete chete kuti "munoda kumanikidzwa kupi?" asiwo "tembiricha yakadii?" uye "muri kumisa sei kuyerera kwemhepo?" Pombi inogona kukonzera kumanikidzwa kwakanyanya kupfuura avhareji yesisitimu. Vharuvhu ingori chikamu chimwe chete chesisitimu yese. Kuziva kuti inogona kubata kumanikidzwa kwakadii hakusi kungoverenga nhamba chete; ndezvekunzwisisa kuti sisitimu yako ichaita sei munyika chaiyo.
Chii chinonzi pressure rating yePVC valve?
Unoona “150 PSI” yakadhindwa pavharuvhu, asi izvozvo zvinorevei chaizvo? Kuishandisa mumamiriro asina kunaka kunogona kukonzera kuti isashande, kunyangwe kana kumanikidzwa kwacho kuchiita sekunge kwakaderera.
Kumanikidzwa kwevharuvhu yePVC, inowanzoita 150 PSI yeSchedule 40, ndiko kumanikidzwa kwayo kwakanyanya kushanda kwakachengeteka patembiricha yemumba. Sezvo tembiricha ichikwira, PVC inonyorova uye simba rayo rekubata kumanikidzwa rinoderera zvakanyanya.
Funga nezvedanho rekumanikidzwa sesimba rayo mumamiriro ezvinhu akanaka. Patembiricha yemukamuri yakanaka ye73°F (23°C), vharuvhu chena yePVC yakajairika yakasimba uye yakasimba. AsiPVC ipurasitiki inodziya, zvinoreva kuti inonyorova kana ikanyanya kupisa. Iyi ndiyo pfungwa yakakosha kunzwisisa: unofanira "kuderedza" kumanikidzwa kana tembiricha yakakwira. Semuenzaniso, pa100°F (38°C), vharuvhu iyoyo ye150 PSI ingangove yakachengeteka kusvika pa110 PSI. Paunosvika pa140°F (60°C), chiyero chayo chepamusoro chinenge chaderera kusvika pa30 PSI. Ndokusaka PVC yakajairwa iri yemigero yemvura inotonhora chete. Kune kumanikidzwa kwakakwira kana tembiricha yakakwira zvishoma, ungatarisaPurogiramu 80 PVC(kazhinji grey yakasviba), ine madziro akakora uye chiyero chepamusoro chekumanikidzwa kwekutanga.
Kuyera Kumanikidzwa kwePVC vs. Tembiricha
| Kupisa Kwemvura | Kumanikidzwa Kwakanyanya (kwevharuvhu yePSI 150) | Simba Rakachengetedzwa |
|---|---|---|
| 73°F (23°C) | 150 PSI | 100% |
| 100°F (38°C) | ~110 PSI | ~73% |
| 120°F (49°C) | ~75 PSI | ~50% |
| 140°F (60°C) | ~33 PSI | ~22% |
Ndeipi muganhu wekumanikidzwa kwevharuvhu yebhora?
Unoziva kuti kumanikidzwa kwesimba remuchina wako kuri pasi pemuganhu wakatarwa. Asi kuvharwa kwevharuvhu kamwe kamwe kunogona kukonzera kukwira kwesimba rinodarika muganho iwoyo, zvichikonzera kuputika ipapo ipapo.
Muganho wekumanikidzwa wataurwa ndewekumanikidzwa kusingachinji, kusingatyisidzike. Muganho uyu haufungi nezvemasimba anoshanduka akaita sesando yemvura, kukwira kwesimba kamwe kamwe kunogona kutyora nyore nyore vharuvhu yakayerwa kumanikidzwa kwakanyanya.
Nyundo yemvura ndiyo inouraya zvinyararire zvikamu zvepombi. Fungidzira pombi refu izere nemvura ichifamba nekukurumidza. Paunovhara vharuvhu, mvura yese inofamba inofanira kumira ipapo ipapo. Simba iri rinoita kuti pave nekudengenyeka kukuru kunodzokera kuburikidza nepombi. Kukwira uku kwesimba kunogona kupetwa ka5 kusvika ka10 kupfuura kumanikidzwa kwesystem kwakajairika. Sisitimu inoshanda pa60 PSI inogona kusangana nekukwira kwe600 PSI kwenguva pfupi. Hapana vharuvhu yebhora yePVC yakajairika inogona kutsungirira izvozvo. Ndinogara ndichiudza Budi kuti ayeuchidze vatengi vake nezveizvi. Kana vharuvhu ikakundikana, zviri nyore kupa mhosva chigadzirwa. Asi kazhinji, dambudziko ndere dhizaini yesisitimu isingatarisiri nyundo yemvura. Nzira yakanakisa yekudzivirira ndeyekuvhara mavharuvhu zvishoma nezvishoma. Kunyangwe nevharuvhu yebhora inotenderera kwekota, kushandisa mubato zvakanaka kwesekondi imwe kana mbiri pane kuivhara kunoita mutsauko mukuru.
PVC inogona kutsungirira kumanikidzwa kwakadii?
Wasarudza vharuvhu chaiyo, asi ko pombi? Sisitimu yako yakasimba chete kana yakabatana zvisina kusimba, uye kutadza kushanda kwepombi kwakaipa sekukundikana kushanda kwevharuvhu.
Huwandu hwekumanikidzwa kunogona kutsungirira PVC hunoenderana ne "purogiramu" yayo kana ukobvu hwemadziro. Pombi yePVC yeStandard Schedule 40 ine mwero wekumanikidzwa wakaderera pane pombi yeSchedule 80 ine madziro akakora uye ari maindasitiri.
Chikanganiso chinowanzoitika kungotarisa pane chiyero chevharuvhu chete. Unofanira kuenderana nezvikamu zvako. Pombi yeSchedule 40 ye 2-inch, iyo pombi chena yaunoona kwese kwese, inowanzo kuve nechiyero che140 PSI. Pombi yeSchedule 80 ye 2-inch, ine madziro akakora uye kazhinji igrey yakasviba, inove nechiyero che200 PSI. Haugone kuwedzera simba rekumanikidza kwesystem yako nekushandisa vharuvhu yakasimba chete. Kana ukaisa vharuvhu yeSchedule 80 (yakayerwa 240 PSI) papombi yeSchedule 40 (yakayerwa 140 PSI), kumanikidzwa kwakanyanya kwakachengeteka kwesystem yako kuchiri 140 PSI chete. Pombi inova iyo link isina simba. Kune chero system, unofanirwa kuona chiyero chekumanikidza chechikamu chimwe nechimwe - mapaipi, fittings, uye mavharuvhu - uye kugadzira system yako kutenderedza chikamu chakaderera.

Mavharuvhu ebhora ePVC akanaka here?
Ukatarisa vharuvhu repurasitiki rakareruka wobva wafunga kuti rinoita serakachipa. Ungavimba zvechokwadi here kuti chikamu ichi chisingadhuri chichava chinhu chakavimbika mugadziriro yako yemvura yakakosha?
Ehe, zvemhando yepamusoroMavharuvhu ebhora ePVCDzakanaka kwazvo pachinangwa chadzo. Kukosha kwadzo hakusi musimba radzo guru, asi mukusaora kwadzo, izvo zvinoita kuti dzive dzakavimbika kupfuura simbi mumabasa akawanda.
Maonero ekuti "kudhura zvakachipa" anobva pakuenzanisa PVC nesimbi. Asi izvi hazvina musoro. Munzvimbo dzakawanda dzekushandisa mvura, kunyanya mukurima, kurima gungwa, kana masisitimu edziva, ngura ndiyo inonyanya kukonzera kukundikana. Vharuvhu yesimbi kana yesimbi ichaita ngura nekufamba kwenguva. Vharuvhu yePVC yemhando yepamusoro, yakagadzirwa ne100% virgin resin ine zvigaro zvePTFE zvakapfava uye maO-rings asina kudzorwa, haizoshande zvakanaka kwemakore munzvimbo inoparadza simbi. Budi inokunda vatengi vasina chokwadi nekuchinja mafomu emubvunzo. Mubvunzo hausi wekuti "purasitiki yakanaka here?" Mubvunzo ndewekuti "simbi inogona kurarama here?" Pakudzora mvura inotonhora, kunyanya uko kune makemikari kana munyu, vharuvhu yePVC yakagadzirwa zvakanaka haisi sarudzo yakanaka chete; ndiyo sarudzo yakangwara, yakavimbika, uye inodhura kwenguva refu.
Mhedziso
Vharuvhu yebhora yePVC inogona kubata 150 PSI patembiricha yemumba. Kukosha kwayo kwechokwadi kuri mukudzivirira ngura, asi nguva dzose tarisa tembiricha nehammer yemvura kuti ive yakachengeteka uye inogara kwenguva refu.
