Ochwepheshe bemboni yokubonisana bangathuthukisa kakhulu inqubo yokukhetha izivalo zemishini. Abathengisi abanolwazi olujulile kanye nesipiliyoni embonini banikeza izixazululo ezenzelwe izidingo ezithile. Lobu buchwepheshe buqinisekisa ukuthi izivalo ezikhethiwe zihlangabezana ngempumelelo nezidingo zokusebenza zesicelo.
Ukubambisana kochwepheshe kuvame ukuhilela izinsizakalo zokubonisana ngokuthembeka. Le nqubo ihlanganisa ukuqonda okuphelele kwezidingo zamakhasimende, kulandelwe ukuhlolwa okuphelele kokuthembeka kwesivalo ngokuhlolwa kwelebhu kanye nokuhlaziywa kokwehluleka. Ukubambisana okunjalo kusiza ekuboneni izinto zokubopha ezifanele kakhulu kanye nobuchwepheshe bezicelo ezithile.
Ngokusebenzisa ukuqonda kochwepheshe kanye nezinsizakusebenza, onjiniyela bangathuthukisa ukuthembeka nokusebenza kahle kwezimpawu zabo zemishini, okuholela emiphumeleni engcono yokusebenza.
Ukuqonda izinhlobo ezahlukene zezivalo zemishini kubalulekile ekwenzeni ngcono izinhlelo zokusebenza zezimboni. Ukukhetha isivalo esifanele kuthuthukisa ukusebenza kahle futhi kunciphisa izindleko zokulungisa. Kunciphisa isikhathi sokungasebenzi kanye nezindleko zabasebenzi ngokunciphisa isidingo sokushintsha nokulungisa njalo.
Izinzuzo Eziyinhloko Zokukhetha Uphawu Olufanele:
- Kuvimbela ukuvuza, kugcina amazinga okukhiqiza futhi kunciphisa ukumosheka kwezinto.
- Kwandisa impilo yemishini ngokunciphisa ukuguguleka nokudabuka.
- Kuthuthukisa ukuphepha ngokuvala okuthembekile, kunciphisa kakhulu umthelela emvelweni.
Uma ungabaza, ukubonisana nochwepheshe kungakunikeza ukuqonda okubalulekile. Isiqondiso sabo siqinisekisa ukuthi uphawu olukhethiwe lwemishini luhlangabezana nezidingo ezithile zokusebenza ngempumelelo.
Imibuzo Evame Ukubuzwa
Kuyini uphawu lomshini?
Isivalo somshini siwumshini ovimbela ukuvuza koketshezi phakathi kwezingxenye ezijikelezayo nezimile emshinini. Sidala isithiyo, siqinisekisa ukuthi uketshezi luhlala lukhona ngesikhathi sokusebenza.
Ngingayikhetha kanjani uphawu olufanele lomshini?
Ukukhetha uphawu olufanele lomshini kuhilela ukuhlola izimo zokusebenza, ukuhambisana kwezinto, kanye nemikhuba yokufaka. Cabangela izidingo ezithile zokufaka isicelo bese uthintana nochwepheshe uma kudingeka.
Yiziphi izinto ezivamile ezisetshenziswa ezivalweni zemishini?
Izinto ezivamile zokuvala okwenziwa ngomshini zifaka phakathi ama-elastomer afana ne-EPDM ne-Viton, izinsimbi ezifana nensimbi engagqwali, kanye nezinto ezithuthukisiwe ezifana ne-PTFE. Ukukhetha kuncike ezicini zoketshezi kanye nezimo zokusebenza.
Kufanele kushintshwe kangaki izivalo zemishini?
Imvamisa yokufakwa kwezimpawu zomshini iyahlukahluka ngokuya ngokusetshenziswa, izimo zokusebenza, kanye nohlobo lwezimpawu. Ukuhlolwa okuvamile kungasiza ekunqumeni ukuthi kudingeka nini ukufakwa kwezimpawu zomshini ukuze kuvinjelwe ukuvuza.
Ingabe izivalo zemishini zingalungiswa?
Ezimweni eziningi, izivalo zemishini azikwazi ukulungiswa. Zenzelwe ukusetshenziswa kanye futhi kufanele zishintshwe uma zibonisa izimpawu zokuguguleka noma ukwehluleka ukugcina ukusebenza kahle.
