Vharuvhu Rekuderedza Kumanikidzwa E Type inoita basa rakakosha mukuchengetedza kumanikidzwa kwemvura kwakaringana kwema hydrant emoto. Inodzivirira zvinobudirira kukuvara kwema hydrant systems kunokonzerwa nekuchinja-chinja kwekumanikidzwa. Nekushanda kwakawedzerwa, izviVharuvhu Yokuderedza Kumanikidzwa Kwemvurazvinovandudza kuchengetedzeka zvakanyanya panguva dzenjodzi dzemoto. Pamusoro pezvo,Vharuvhu Yokuderedza Kudzvanywa KwekugadzikauyeVharuvhu Yekuderedza Kudzvinyirirazvinhu zvakakosha zvinovimbisa kushanda kwakavimbika mumamiriro ezvinhu akaoma.
Kukosha kweMavharuvhu Ekuderedza Kudzvanywa
Basa muMagadzirirwo eMadziviriro eMoto
Mavharuvhu ekuderedza kumanikidzwa (PRVs) anoshanda basa rakakosha mumasisitimu emvura inodzima moto. Anodzora kumanikidzwa kwemvura, zvichiita kuti irambe iri mukati memiganhu yakachengeteka. Mutemo uyu wakakosha pakudzivirira vanodzima moto nepfuma kubva mukukuvadzwa kunogona kukonzerwa nemvura ine kumanikidzwa kwakanyanya. Tafura inotevera inotsanangura mabasa makuru emavharuvhu ekuderedza kumanikidzwa mumasisitimu emvura inodzima moto:
| Tsananguro yeBasa |
|---|
| Kuderedza kumanikidzwa kwesystem uye kuideredza. |
| Kuderedza mwero wekumanikidzwa kubva kudunhu guru kuenda kudunhu repasi. |
| Kudzora kumanikidzwa kwesystem muzvikamu zvakati zvedunhu. |
| Kudzivirira kumanikidzwa kwakanyanya kwesystem kuti kusasvike padanho risina kuchengetedzeka. |
| Kudzivirira hurongwa kubva pakumanikidzwa kwakanyanya kwehurongwa. |
| Kuramba uchimanikidzwa zvakanyanya kunyangwe paine kumanikidzwa kwakasiyana-siyana. |
Nekuchengetedza huwandu hwakagadzikana hwekumanikidzwa, maPRV anobatsira kuderedza njodzi yekubuda kwemvura uye kuputika kwemapombi. Zvakaratidzwa kuti anoderedza mwero wekubuda kwemvura ne31.65%, zvichideredza kutambisa mvura. Uyezve, kuiswa kwemaPRV kunoita kuti mapaipi apwanyike zvishoma, izvo zvinoderedza mari yekugadzirisa nekutsiva. Kuvimbika uku kunoita kuti sisitimu yemvura irambe isina kukanganiswa panguva dzenjodzi.
Kukanganiswa Kwekumanikidzwa Kwemvura
Kugara kwenguva refu kwesimba remvura kwakakosha pakushanda zvakanaka kwemapombi emvura anodzima moto panguva dzenjodzi.Kumanikidzwa kwemvura kwakanyanya kunogona kukuvadza zvinhu zvakakosha, zvichikonzera kutadza kwemidziyo. Kuchinja-chinja kwesimba remagetsi kunokanganisa mashandiro ekudzima moto, zvichiita kuti zviomere vadzimi vemoto kuchengetedza mvura yakadzikama. Kumanikidzwa kwakanyanya kunogonawo kuchinja maitiro ekupfapfaidza ezvipfapfaidzo kana ma nozzles, zvichideredza kushanda kwazvo uye zvichinonotsa kudzima moto.
Huwandu hwekumanikidzwa hunokurudzirwa hwekushanda kwemvura inodzima moto, zvichienderana nezvinodiwa neindasitiri, hunosimbisa kukosha kwekuchengetedza kumanikidzwa kwakasimba. Semuenzaniso, NFPA 24 (2019) inoratidza kuti masisitimu asina pombi yemoto haawanzopfuura 150 PSI mumapombi epasi pevhu. Pamusoro pezvo, NFPA 291 inokurudzira kuchengetedza kumanikidzwa kwakasara kwe20 PSI kuti kudzima moto kubudirire.
Zvinhu zviri muDhivhavha Rekuderedza Kumanikidzwa E Type
Dhizaini uye Mashandiro
Vharuvhu reE Type Pressure Reducing rine dhizaini yakasimba yakagadzirirwa kushanda zvakanaka mumasystem emvura inodzima moto. Kugadzirwa kwayo kunoshandisa brass yemhando yepamusoro, ichivimbisa kugara kwenguva refu uye kuramba ngura. Vharuvhu iyi ine inlet yakapinza kana kuti yakakungurutswa, zvichibvumira sarudzo dzakasiyana siyana dzekuisa.
Zvimiro zvakakosha zvekugadzira zvinosanganisira:
| Chinhu | Zvidimbu |
|---|---|
| Zvinhu | Ndarira |
| Musuwo wekupinda | 2.5” BSPT |
| Nzvimbo yekubuditsa zvinhu | 2.5” BS yemukadzi pakarepo |
| Kumanikidzwa kushanda | 20 bhawa |
| Kudzvinyirirwa kwemhepo kunoderera | mabhawa mashanu kusvika kumabhawa masere |
| Kumanikidzwa kwekunze nguva dzose | 7 bha kusvika 20 bha |
| Kumanikidzwa kwekuyedza | Kuongororwa kwemuviri pa30 bar |
| Mwero wekufamba kwemvura wakaderera | Kusvika ku1400 L/M |
Vharuvhu yerudzi rweEinodzora kumanikidzwa kwemvuranekugadzirisa kuyerera kwemvura kubva kumvura huru. Inovhura kana kuvhara yega zvichienderana nekuchinja kwekumanikidzwa kwekupinda kuti irambe yakasimba pakubuda. Iyi nzira inoita kuti mvura iwanikwe zvakanaka kune vanodzima moto, pasinei nekuchinja-chinja kwekumanikidzwa kwesystem.
Kugara kwenguva refu uye Kuvimbika
Kugara kwenguva refu chiratidzo chevharuvhu rekuderedza kumanikidzwa kwerudzi rweE. Mumamiriro ekushanda akajairwa, vharuvhu iyi ine avhareji yehupenyu hwemakore angangoita masere. Zvisinei, hupenyu hwevharuvhu iyi hunogona kusiyana zvichienderana nemaitiro ekugadzirisa uye mamiriro ekushanda. Kugadziriswa nguva dzose, kwakadai sekugadzirisa makore maviri kusvika mana ega ega, kunogona kuwedzera zvakanyanya hupenyu hwevharuvhu.
Kuvimbika kwevharuvhu yerudzi rweE kunobva mukuita kwayo kwakaoma. Vharuvhu yega yega inoedzwa muviri wayo pa30 bar, zvichiratidza kugona kwayo kutsungirira mamiriro ekumanikidzwa kwakanyanya. Kuyedzwa uku kunopa rugare rwepfungwa kune vashandisi, vachiziva kuti vharuvhu ichaita zvakanaka panguva yemabasa akakosha ekudzivirira moto.
Kana tichienzanisa nedzimwe mhando dzevharuvhu dzinoderedza kumanikidzwa, E Type inopa dhizaini iri nyore ine zvikamu zvishoma, zvichiita kuti ive sarudzo isingadhuri. Zvisinei, zvakakosha kuziva kuti inogona kunge iine miganho mukumanikidzwa kwekudzima uye kumhanya kweactuator. Izvi zvinoita kuti ive yakakodzera kunyanya kushandiswa kune shanduko dzinononoka dzekuremerwa.
Kazhinji, vharuvhu yekuderedza kumanikidzwa kwerudzi rweE inosiyana nekusanganiswa kwayo kwedhizaini inoshanda, kushanda kwakavimbika, uye kugara kwenguva refu, zvichiita kuti ive chinhu chakakosha mumasystem emvura inodzima moto.
Kuiswa uye Kugadziriswa kweE Type Valve
Maitiro Akanakisisa Ekuisa
Kuisa vharuvhu reE Type Pressure Reducing Valve nemazvo kwakakosha kuti pave nekushanda zvakanaka. Kutevedzera nzira dzakanakisisa kunogona kudzivirira zvikanganiso zvinowanzo itika pakuiisa. Heano pfungwa huru dzekufunga nezvadzo:
- Kuiswa Kwakamira: Gara uchiisa vharuvhu yakatwasuka kuti usanyanya kushanda zvakanaka uye uve nechokwadi chekuti mvura inoyerera zvakanaka.
- Tsigirai Kuburitsa Mapaipi: Iva nechokwadi chekuti mapombi ekubuditsa mvura anotsigira huremu hwawo. Izvi zvinodzivirira kushushikana kwevharuvhu, izvo zvinogona kukanganisa mashandiro ayo.
- Chengetedza Kusiyanisa Kumanikidzwa: Chengetedza musiyano wakakodzera pakati pekushanda nekumanikidzwa kwakaiswa. Izvi zvakakosha pakushanda kwevharuvhu.
Kushandisa maturusi akakodzera kunowedzerawo kushanda zvakanaka kwekuisa. Maturusi anokurudzirwa anosanganisira:
- Chiyero chekumanikidza
- Chipanera chepombi
- Mucheka wechubhu
- Chipanera chakavhurika
- Sikuruudhiraivha
Mazano Ekugadzirisa Nguva Dzose
Kugadzirisa nguva dzose kwakakosha kuti vharuvhu yeE Type ive yakareba uye yakavimbika. Kuongorora nguva dzose kunobatsira kuona matambudziko angangoitika asati awedzera. Tafura inotevera inotsanangura mabasa ekugadzirisa anokurudzirwa uye kuwanda kwawo:
| Kakawanda | Basa Rekugadzirisa |
|---|---|
| Mwedzi wega wega | Ongorora vharuvhu nemapaipi nemaziso. Chenesa chikweshero cheY negomba. |
| Kota yega yega | Tarisa diaphragm yePRP woitsiva kana zvichidikanwa. Tarisa diaphragm yevharuvhu huru nechigaro kuti chionekwe kuti chakasakara here. |
| Gore negore | Ongorora zvizere zvikamu zvese zvevharuvhu. Tsiva zvikamu zvakasakara kana zvakakuvara kuti uve nechokwadi chekuti zvinoshanda zvakanaka. |
Maitiro ekugadzirisa anoshandazvinosanganisira:
- Kuongorora nguva dzose kuti uone matambudziko angangoitika.
- Kuchenesa nekuzora mafuta ezvikamu zvinofamba kuti zvisaparare.
- Kutarisa kana paine mvura inodonha kuti ive nechokwadi chekuti sisitimu yacho yakachengeteka.
Nekutevedzera izvinhungamiro dzekuisa nekugadzirisa, vashandisi vanogona kuve nechokwadi chekuti E Type Pressure Reducing Valve inoshanda nemazvo, ichipa simba remvura rakavimbika panguva yemabasa akakosha ekudzivirira moto.
Vharuvhu reKuderedza Kumanikidzwa kweRudzi rweE rinosimudzira kushanda zvakanaka uye kuchengetedzeka kwemvura inodzima moto. Kugara uchitarisira kumanikidzwa kunoita kuti pave nekupindura nekukurumidza. Kuisa mari mumavharuvhu eE Type kunobatsira, sezvo kunoderedza kubuda kwemvura uye kupwanyika kwemapaipi, izvo zvinoderedza kukanganiswa uye zvinodzivirira zvivakwa. Kudyara mari uku kwakakosha kune masisitimu ekuchengetedza moto anoshanda zvakanaka.
