Mapaipi Akasungirirwa Arc Akanyudzwa Kaviri Kuti Awedzere Kusimba Kwechivakwa

Tsananguro pfupi:

Chikamu chino cheEuropean Standard chinotsanangura mamiriro ekugadzirwa kwezvinhu zvekuvaka zvakagadzirwa nesimbi dzakasungirirwa, dzine maburi edenderedzwa, sikweya kana rectangular uye chinoshanda kuzvikamu zvekuvaka zvisina maburi zvakagadzirwa nesimbi dzinotonhora pasina kurapwa kwekupisa kunotevera.

Munyaya yeinjiniya yekuvaka, kukosha kwekushandisa zvinhu zvemhando yepamusoro uye nzira dzekuvaka hakufanirwe kutaurwa zvakanyanya. Pakati pezvinhu zvakasiyana-siyana zvinoshandiswa mumapurojekiti ekuvaka, mapaipi anoita basa rakakosha. Tichajekesa kukosha kwemapaipi akasungirirwa kaviri uye tichaongorora hunhu hwawo, mabhenefiti awo uye kuti angabatsira sei kusimudzira kunaka kwechivako.

Dzidza nezvemapombi akasungirirwa kaviri:

Pombi dzakasungirirwa kaviri, inozivikanwawo sepombi dzakasungirirwa kaviri dzakanyudzwa pasi pemvura (Mapaipi eDSAW), inogadzirwa uchishandisa nzira yekuwedera arc iri pasi pemvura. Tekinoroji iyi inosanganisira kubatanidza maplate maviri esimbi akasiyana kwenguva refu, zvichipa kubatana kwakasimba uye kunogara kuripo. Mapaipi aya anonyanya kushandiswa mukushandiswa kwesimba rakawanda, mapaipi epasi pevhu negasi rechisikigo, kutsvaga mafuta, uye mapuratifomu ekunze kwegungwa.

Kuvandudza kusimba kwechimiro:

Chikonzero chikuru chekushandisapombi dzakasungirirwa kavirikugona kwavo kusimudzira kunaka kwechimiro. Nekupinza kwakasimba uye kusina musono, mapaipi aya anopa simba uye anoramba kwenguva refu. Kupinza kwakapetwa kaviri kunoita kuti paipi ikwanise kumira kumanikidzwa kwakanyanya, zvichiita kuti ive yakakodzera kushandiswa kwakakosha apo kupinza kamwe chete kunogona kukanganisa kuchengetedzeka kwechimiro. Maitiro aya ekupinza kaviri anobvisa mukana wekudonha kana kutsemuka, zvichiita kuti system yako yemapaipi ive yakavimbika kwenguva refu.

Simba rakakwirira pakurema:

Mapaipi akasungirirwa kaviri anopa simba rakanaka pakuyera huremu. Nekuda kwemaitiro ekushongedza, mapaipi aya ane ukobvu hwakaderera uye akareruka uku achichengetedza kuomarara kwechimiro. Iyi mukana wesimba pakuyera huremu unoderedza mutoro wese pachivako chinotsigira, zvichiita kuti ive mhinduro inodhura zvishoma kumapurojekiti makuru akadai semabhiriji, shongwe, uye zvivakwa zvirefu.

Kuramba ngura:

Chimwe chinhu chakakosha chepombi dzakasungirirwa kaviri ndechekudzivirira kwayo ngura. Chisimbiso chakasimba chakasungirirwa chinoita kuti pave nechidziviriro chakasimba kubva kune zvimwe zvinhu zvekunze, zvinosanganisira hunyoro, makemikari uye hunhu hwevhu. Izvi zvinodzivirira mukati mepombi kuti isabatane zvakananga nezvinhu zvinokanganisa ngura, zvichiita kuti igare kwenguva refu kana tichienzanisa nemapombi ekare. Hunhu hunodzivirira ngura hwemapombi aya hunonyanya kubatsira indasitiri yemafuta negesi, uko mapaipi anowanzo sangana nemamiriro ezvinhu akaoma.
