Mutengo uye Kugona Kugadziriswa kweLanding Valve

Kuenzanisa Mutengo: Brass vs. Bronze

Brass nebronze zvakasiyana zvakanyanya pamutengo wazvo nekuda kwekuumbwa kwazvo uye kuwanikwa kwazvo. Brass, inoumbwa zvakanyanya nemhangura ne zinc, inowanzo kuve yakachipa. Kushandiswa kwayo zvakanyanya mumapombi nemaindasitiri kunoita kuti ive nemutengo wakaderera. Bronze, ine mhangura ne tin, inowanzoita kuti ive nemitengo yakakwira nekuda kwekushomeka kwe tin uye alloys dzakagadzirwa dzinodiwa pakushandiswa kwadzo.

Vagadziri vanowanzo sarudza brass yekuisa mavharuvhu ekumisa kana mutengo uchikosha. Bhurandi, kunyange zvazvo ichidhura zvakanyanya, inopa simba rakawanda uye inodzivirira ngura, zvichiita kuti ive sarudzo inofarirwa munzvimbo dzine kushushikana kwakanyanya. Sarudzo pakati pezvinhu izvi inoenderana nekuenzanisa bhajeti nezvinodiwa pakushanda.

Kufunga Nezvekugadzirisa uye Kugadzira

Kugona kugadzira machina kunoita basa rakakosha pakuona kuti zviri nyore kugadzira mavharuvhu ekumisa machina. Brass inoratidza kugona kwayo kugadzira machina nekuda kwekugona kwayo kuchinjika uye kuoma kwayo kwakaderera. Izvi zvinoita kuti vagadziri vagadzire magadzirirwo akaomarara asina kushandiswa zvakanyanya. Brass, kunyange zvazvo yakasimba, ine matambudziko makuru panguva yekugadzira machina nekuda kwekuoma kwayo kwakanyanya uye simba rayo rekusunga.

Tafura iri pazasi inoratidza zviyero zvakakosha zvekugadzira machinability yebrass nebronze alloys:
