• Vuto la manometer silikugwirizana ndi chizindikiro chomwe wopanga amapanga.

Kodi kuyeza kwa manometers kumachitika bwanji?

Monga tawonera kale, pali kuyerekezera koyambirira ndi kobwerezabwereza kwa maginito opanikizika. Njira zoyambirira zimachitika panthawi yopanga isanagulitsidwe. Kutsimikiza kumakhala kovomerezeka kwa chaka chimodzi kapena ziwiri. Nthawiyi idzawonetsedwa pachizindikiro chokhazikika pamtundu wa chipangizocho kapena pasipoti yake.

Pambuyo pa nthawi imeneyi, chipangizocho chimafuna kuyambiranso. Poterepa, iyenera kugwiridwa. Ngati pali kukayikira za izi, ndibwino kuti mugule kuyeza kwatsopano, chifukwa ndalama zowunika momwe chipangizochi sichitha kugwira ntchito sizinabwezeredwe.

Kumapeto kwa kuwunikaku, timapereka ma gauges TOP-5 a 2021:

TOP-5. Makina abwino opanikizika. Mndandanda wa 2021!

Kanema pa mutuwo

Pomaliza - nkhani yachidule ya kanema pakugwiritsa ntchito ma geji okakamiza:

Phunziro 58 (lalikulu). Zoyezera kuthamanga

Mafunso ndi Mayankho:

Kodi ma unit of measurement a pressure gauge ndi ati? Makina onse opanikizika amayesa kupanikizika m'magawo otsatirawa: bar; kilogalamu mphamvu pa lalikulu sentimita; mamilimita amtundu wamadzi; mamilimita a mercury; mamita a gawo lamadzi; mlengalenga waluso; ma newtons pa mita imodzi (pascals); megapascals; magwire.

Kodi kuyeza mopanikizika kumagwira ntchito bwanji? Kupanikizika kumayesedwa ndi zomwe zimachitika pakukakamira kwa zotanuka pazida zolumikizidwa ndi muvi. Zotanuka ndizopunduka, chifukwa chake muvi umabwerera, kuwonetsa mtengo wofanana. Kuti muyese kupanikizika kwa mphamvu inayake, pamafunika chida chomwe chimatha kupirira mutu katatu pamtengo woyenera.

Kodi kuyeza kwachangu kumakhala ndi chiyani? Ichi ndichida chachitsulo chokhala ndi chitsulo (osakhala pulasitiki) thupi ndi chivundikiro chagalasi. Mulingo ndi muvi zimawoneka pansi pagalasi. Kumbali (mumitundu ina kumbuyo) kuli ulusi wolumikizidwa. Mitundu ina imakhalanso ndi batani lothanirana ndi thupi. Iyenera kukanikizidwa nthawi zonse mukayesa kupanikizika (izi ndizofunikira kuti zotanuka sizikukakamizidwa nthawi zonse ndipo sizipunduka). Pali makina mkati mwa chipangizocho, gawo lalikulu lomwe ndichinthu chotanuka cholumikizidwa ndi muvi. Kutengera ndi cholinga cha chipangizocho, makinawo amasiyana ndi mtundu wosavuta.
