Semugadziri anotungamira wemavharuvhu emhando yepamusoro, ZFA inowanzo gamuchira mibvunzo nezvemusiyano uripo pakati pemhando dzakasiyana dzemavharuvhu. Mubvunzo unowanzo bvunzwa ndewekuti: Chii musiyano uripo pakati pevharuvhu yeshavishaviuyevharuvhu yekutarisa shavishaviKunyange zvazvo vaine mazita akafanana uye vese vachishandisa dhizaini yedhisiki, mabasa avo, mashandiro avo, uye mashandisirwo avo akasiyana zvikuru.
Gwaro iri rinotsanangura musiyano mukuru uyu, richishandisa hunyanzvi hweZFA. Tichakurukura zvinhu zvekutanga—zvakaita setsanangudzo, dhizaini, uye misimboti yekushanda. Ungave uri mainjiniya, nyanzvi yekutenga, kana nyanzvi yeindasitiri, chinyorwa chino chichakubatsira kuita sarudzo ine ruzivo.
1. Chii chinonzi vharuvhu reshavishavi?
Vharuvhu yemapuruguru ivharuvhu inotenderera inotenderera nekota inoshandiswa kudzora kuyerera kwemvura kana kupatsanura mapombi. Ine dhisiki inotenderera pakati kuti ivhure kana kuvhara nzira yekuyerera kwemvura.
1.1 Mashandiro Anoita Vharuvhuti
Vharuvhu inoshanda nekutenderedza dhisiki nemadhigirii makumi mapfumbamwe: yakavhurika zvizere, ichibvumira kuyerera kusina kuvharwa, kana kuvharwa, ichivhara nzira yekuyerera. Kutenderera zvishoma kunobvumira kutenderera, zvichiita kuti ive yakakodzera kudzora kuyerera.
1.2 Mashandisirwo Akajairika
- Zvirimwa Zvekuchenesa Mvura
- Masisitimu eHVAC
- Kugadziriswa kweMakemikoro
- Indasitiri yeChikafu neZvinwiwa
2. Chii chinonzi Butterfly Check Valve?
Vharuvhu yekutarisa butterfly, inozivikanwawo sevharuvhu yekutarisa madhisiki maviri, ivharuvhu isingadzokeri kana kuti vharuvhu yenzira imwe chete inodzivirira kudzokera shure mumapaipi. Kusiyana nemavharuvhu ebutterfly, inoshanda yega pasina kufambiswa kwekunze.
2.1 Nheyo yeKushanda
Kuyerera kwemhepo kunosunda dhisiki kuti ivhurike, zvichikunda kushushikana kwechitubu. Kana kuyerera kwamira kana kudzokera shure, chitubu chinovhara dhisiki nekukurumidza, zvichiita kuti ivhare zvakasimba kudzivirira kuyerera kwemhepo. Kushanda uku kwega hakudi kupindira kwevanhu.
2.2 Mashandisirwo Akajairika
- Mitsetse Yekuburitsa Pombi
- Masisitimu eCompressor
- Mapuratifomu eMarine neOffshore
- Kutarisira Mvura Yakasviba
3. Musiyano Mukuru Pakati peMavharuvhu eButterfly neMavharuvhu ekuongorora Butterfly
Kunyange zvazvo ese ari maviri achishandisa nzira yedhisiki, mashandisirwo awo makuru akasiyana. Heino kuenzanisa kunoenderana:
| Chikamu | Vharuvhu yeBhatafurayi | Vharuvhu Yekutarisa Bhatafurayi |
| Basa Guru | Kudzora kuyerera kwemvura uye kupatsanurwa | Kudzivirira kudzokera shure |
| Kushanda | Kutenderera nemaoko kana kuti nemaoko | Otomatiki (yakazadzwa nechitubu) |
| Dhizaini yeDiski | Dhisiki imwe chete pamugodhi | Mahwendefa maviri ane hinges nezvitubu |
| Kutungamirirwa Kwemvura | Nzira mbiri (nekuvharwa kwakakodzera) | Nzira imwe chete chete |
| Kuiswa | Wafer, lug, kana kuti flanged | Wafer, lug, kana kuti flanged |
Tafura iyi inoratidza zvikonzero zvekusarudza rimwe pane rimwe: mavharuvhu eshavishavi ekudzora, tarisa mavharuvhu ekudzivirira.
6. Nyundo yemvura uye kumhanya kwekupindura
Nyundo yemvura inowanzo itika kana kuyerera kwemvura kwangoerekana kwamira, senge kana vharuvhu yavharwa nekukurumidza kana pombi yangoerekana yadzimwa. Izvi zvinoita kuti kinetic energy ichinje kuita pressure wave inopararira ichitevedza pombi. Kuvhunduka uku kunogona kukonzera kuputika kwepombi, kusunungura flange, kana kukuvara kwevharuvhu. Mavharuvhu eButterfly nemavharuvhu ekuongorora butterfly akasiyana mukukwanisa kwawo kubata mvura nekuda kwemagadzirirwo awo uye nzira dzekushandisa.
6.1 Mavharuvhu eBhabhatafurayi neHammer yemvura
Kumhanya kunovharwa vharuvhu yemapuruguru kunoenderana nenzira yainoshandiswa nayo (nemaoko, nemhepo, kana nemagetsi). Kuvhara nekukurumidza kunogona kukonzera mvura, kunyanya mumasisitimu ane mwero wekuyerera kwakanyanya kana kumanikidzwa kwakanyanya. Izvi zvinoda kutarisirwa kwakanyanya mumasisitimu epombi.
Mavharuvhu emashavishavi haana kugadzirwa kudzivirira kudzoka kwemvura. Kana paine njodzi yekudzokera kwemvura musystem, nyundo yemvura inogona kuwedzerwa nekudzokera kwemvura.
6.2 Mavharuvhu Ekuongorora Mashavishavi neHammer Yemvura
Mavharuvhu ekuongorora mashavishavi (mavharuvhu ekuongorora madhisiki maviri) anovhara otomatiki achishandisa madhisiki maviri ane spring-loaded kudzivirira kudzokera shure. Akagadzirwa kuti apindure nekukurumidza kune shanduko munzira yekuyerera uye ave nechokwadi chekuvharika ipapo ipapo kana mvura yamira kana kudzokera shure, zvichidzivirira sisitimu kubva mukukuvadzwa kwekudzokera shure. Zvisinei, kuvhara uku nekukurumidza kunogona kukonzera mvura.
7. Mibvunzo Inowanzo bvunzwa
Ndingakurumidza sei kusiyanisa pakati pevharuvhu remapuruguru nevharuvhu rekutarisa?
Mavharuvhu eshavishavi ane maatomu, nepo mavharuvhu ekuongorora asina.
Vharuvhu yeshavishavi inogona kushandiswa sevharuvhu yekutarisa here?
Kwete, nekuti haina nzira yekuvhara otomatiki. Zvakasiyana nazvo ndezvechokwadiwo.
Mavharuvhu aya anoda kugadziriswa sei?
Mavharuvhu eshavishavizvinoda kuongororwa kwechigaro nguva dzose;mavharuvhu ekuongororazvinoda kuongororwa kwechirimo mwedzi 6-12 yega yega.
