Nezvemaumbirwo eplate yebhatafurayi yevharuvhu hombe ine dhayamita, AWWA C504 (American Water Supply Engineering Association Standard) inoti plate yebhatafurayi haifanirwe kunge ine mbabvu dzakachinjika, uye ukobvu hwayo haufanirwe kupfuura dhayamita yedanda revharuvhu neka2.25.
Nzvimbo inopinda nemvura uye nzvimbo inopinda mvura mupumburu webhatafurayi inofanira kunge yakarongeka.
Zvikuruu zvemukati hazvigone kubuda kunze kweplate yeshavishavi, kuitira kuti zvisawedzere nzvimbo yakatarisana nemvura.

2.2 Chisimbiso cherabha
Dzimwe nguva hupenyu hwekushanda kwevharuvhu rerubhata hupfupi, izvo zvine chekuita nehunhu hwerabha uye upamhi hwepamusoro pechisimbiso. Mhete yekuvharira yevharuvhu rerubhata rakavharirwa inofanira kugadzirwa nezvinhu zverabha zvemhando yepamusoro, uye mitemo yekushanda inofanira kuteverwa panguva yekumanikidza kuumbwa. Tembiricha ye vulcanization haifanirwe kuwedzerwa zvisina kurongeka, uye nguva inogona kupfupikiswa, zvikasadaro ichaita kuti mhete yekuvharira ikwegure uye itsemuke. Nzvimbo yekuvharira yesimbi inoenderana nemhete yekuvharira yerubhata inofanira kunge yakafara zvakakwana, zvikasadaro mhete yekuvharira yerubhata haisi nyore kuiisa. Pamusoro pezvo, kushivirira kwechimiro nenzvimbo, kuenzanisa, kunyatsojeka, kutsvedzerera, uye kusimba kwemhete yekuvharira yemuviri wevharuta neplate yerubhata zvinokanganisawo hupenyu hwemhete yekuvharira yerubhata.
2.2 Kuomarara
Kuomarara inyaya yakakosha pakugadzirwa kwemavharuvhu eshavishavi, izvo zvine chekuita nezvinhu zvakaita semaplate eshavishavi, migero yemavharuvhu uye zvinobatanidzwa.

(1) Saizi yemubato wevharuvhu Saizi yemubato wevharuvhu yakatsanangurwa muAWWA C504. Kana saizi yemubato wevharuvhu isingasvike zvinodiwa, panogona kunge pasina kuomarara kwakakwana, kudonha kwechisimbiso chemashure, uye torque huru yekuvhura. Kuoma kwemubato kwakabatana ne1/EI, kureva kuti, kuti tivandudze kuomarara uye kuderedza dambudziko rekuchinja, tinofanira kutanga nekuwedzera EI. E ndiyo modulus yekusimba. Kazhinji, musiyano wesimbi hausi mukuru, uye chinhu chakasarudzwa hachina simba guru pakuomarara. I ndiyo nguva yekusashanda uye ine hukama nehukuru hwechikamu chemubato. Saizi yemubato wevharuvhu inowanzo kuverengerwa zvichienderana nekusanganiswa kwekukombama netorsion. Haina hukama chete netorque, asiwo inonyanya hukama nenguva yekukombama. Kunyanya, nguva yekukombama yevharuvhu rebhururu rakakura rakakura kupfuura torque.
(2) Kubatana kwegomba remugodhi Shanduro yekare yeAWWA C504 inoti shaft yevharuvhu yebhatafurayi ishaft yakatwasuka. Mushure meshanduro ya1980, zvakakurudzirwa kuti inogona kugadzirwa kuita shaft mbiri pfupi. Sekureva kweAWWA C504 naGB12238, kureba kweshaft negomba zvakavharirwa kunofanira kuva 1.5d. Musiyano (C value) uri pakati pemucheto wemuviri wevharuvhu nemagumo ekutsigira eplate yebhatafurayi muchikamu cheaxial chevharuvhu yebhatafurayi yeJapan wakatsanangurwa, izvo zvinowanzoenderana nehukuru hwedhayamita, iri pakati pe25 ne45mm, izvo zvinoderedza daro riri pakati pezvinotsigira shaft (C value), nokudaro zvichideredza nguva yekukotama uye kushanduka kweshaft.
(3) Chimiro chepuratifomu rebhatafurayi Chimiro chepuratifomu rebhatafurayi chine hukama hwakananga nekuomarara, saka pamusoro pechimiro chepuratifomu rakati sandara, chinonyanya kugadzirwa kuita chimiro chehari kana chimiro chetruss. Muchidimbu, ndechekuwedzera nguva yekusasimba kwechikamu kuti chiwedzere kuomarara.
(4) Magadzirirwo emuviri wevharuvhu Kunewo matambudziko ekuomarara mukugadzirwa kwemuviri wevharuvhu reshavishavi rakakura. Kazhinji, kune rin'i neribhamu. Kutaura zvazviri, rin'i dzinongowedzera kugadzikana uye hadzifanirwe kunge dzakawanda. Dzinonyanya kukosha irin'i. Kana ukakwanisa kuwedzera ∩-shaped ribs, zvichabatsira zvikuru pakuomarara kwadzo, asi pane dambudziko rekusagadzirwa zvakanaka.
2.3 Mabheringi anozvizora ega
Kudzvinyirira kwakawanda kana kwese kwepakati papuratifomu yeshave (reverse) kunoendeswa kubheyaringi kuburikidza neshave, saka bearing inoita basa rakakosha. Mamwe mavharuvhu eshave ekunze akareruka uye ari nyore kushandisa, uye mavharuvhu madiki anogona kutenderedzwa nemunwe mumwe chete, nepo mamwe mavharuvhu eshave epamba achirema. Kuwedzera kune coaxiality, symmetry, processing accuracy, kupedzisa uye mhando yekurongedza, chinhu chakakosha ndechekunyorova kwechinhu chesleeve. Standard yeAWWA C504 inokurudzira kuti shave sleeve kana bearing yakaiswa mumuviri wevharuvhu inofanira kunge iri yekuzvizora, uye shave sleeve ine dambudziko rekuderedza kukweshana uye mafuta, uye ngura haibvumidzwe. Pasina shaft sleeve, kunyangwe shaft yevharuvhu iri simbi isina tsvina, muviri wevharuvhu une matambudziko engura nekunamatira. Kushandiswa kwebushings kunogonawo kuwedzera kuomarara.

2.4 Kubatana kwemugodhi nepureti remapuruguru
Mubato nepureti yebhururu rebhururu rebhururu rediki zviri nani kuti zvibatanidzwe nekiyi kana spline, uye kubatana kwemubato wepolygonal kana pin kunogonawo kushandiswa. Mubato nepureti yebhururu rebhururu rebhururu rehukuru hwakakura zvinonyanya kubatanidzwa nemakiyi kana mapini etaper. Parizvino, mashaft nemadisc akawanda zvakabatana nemapini. Pini yekubatanidza inokuvadzwa mumamiriro ekushanda akaoma. Izvi zvinonyanya kukonzerwa nezvikonzero zvekugadzira. Pakati pazvo, kururama kweanastomosis hakuna kunaka, saizi yepini haina kukodzera, kuoma kwepini hakuna kukwana kana zvinhu hazvina kukodzera, nezvimwewo, zvinofanira kutariswa. Mubato nepureti yebhururu rebhururu reguru rebhururu reguru zvinogona kubatanidzwa nenzira yakakosha.
