Isikhathi esinconyiwe sokushintsha uwoyela we-hydraulic emishinini yokumba ngokuvamile sisukela kumahora angu-1,000 kuya kwangu-2,000 okusebenza, kuye ngemibandela yomenzi, izimo zokusebenza, kanye nekhwalithi kawoyela osetshenziswayo. Imishini yokumba esebenza ezindaweni ezinzima ezinokushisa okuphezulu, uthuli oluningi, noma imithwalo esindayo eqhubekayo ingadinga ukushintshwa kukawoyela njalo ukuze kugcinwe ukuthambisa okufanele kwepompo nokuvikelwa kwesistimu. Ukuhlaziywa kukawoyela njalo kuyindlela engcono kakhulu yokunquma isikhathi esifanele sokushintsha ngaphansi kwezimo zakho zokusebenza, ngoba kunikeza imininingwane ngesimo sikawoyela, amazinga okungcola, kanye nokuncipha kwezithako.

Amaphampu e-Axial piston aziwa emhlabeni wonke njengokukhetha okungcono kakhulu kwezifunda eziyinhloko zomgubho ngoba anikeza amandla okucindezela aphezulu, ukulawula kokushintsha kwevolumu, kanye nokusebenza kahle kwevolumu okudingekayo ekusebenzeni okunzima kokumba nokuphakamisa. Isici sokushintsha kwevolumu sivumela lawa maphampu ukuthi afanise ukuphuma kwevolumu nesidingo sesistimu, kunciphisa ukusetshenziswa kukaphethiloli nokukhiqiza ukushisa uma kuqhathaniswa nezinye izindlela ezingaguquki zevolumu. Amaphampu e-MKS Hydraulic e-axial piston akhelwe ngokukhethekile ukusetshenziswa emagubhini, enokwakheka okuqinile nezinketho zokulawula ezithuthukisiwe ezithuthukisa ukusebenza kuzo zonke izimo zokusebenza.

Isinqumo sokulungisa noma ukushintsha iphampu yomgubhu elimele sincike ezingeni lokulimala, izindleko zezingxenye zokushintsha uma kuqhathaniswa nephampu entsha, kanye nesimo sonke sesistimu ye-hydraulic. Ukulimala okuncane njengama-seal agugile noma ama-bearing kuvame ukulungiseka ngezindleko eziphansi, ikakhulukazi kumaphampu asezingeni eliphezulu anezingxenye zokulungisa ezitholakalayo. Nokho, uma iphampu ilimale kakhulu ngaphakathi futhi ukungcola kusakazeke kuyo yonke isistimu, ukushintsha kuvame ukuba yisinqumo esithembekile nesonga izindleko, ngoba izindleko zokwakha kabusha ngokuphelele zingasondela noma zeqe intengo yephampu entsha ye-MKS enewaranti ephelele.

Ukusebenza kahle kwepompo kuthinta ngqo ukusetshenziswa kukaphethiloli womshini wokumba ngoba noma yimaphi amandla alahleka njengokushisa ngaphakathi kwepompo kufanele abuyiselwe ngokushisa uphethiloli owengeziwe enjinini. Ipompo elisebenza kahle kakhulu elinamandla okusebenza angu-95% lilahlekelwa kuphela u-5% wamandla okufakwayo njengokushisa, kanti ipompo eligugile noma elingafaneleki elisebenza ngamandla angu-80% lilahlekelwa u-20% wamandla enjini njengokushisa okungadingekile okubuye kucindezele uhlelo lokupholisa. Ukukhetha ipompo elisezingeni eliphezulu, elilinganiswe kahle kwa-MKS Hydraulic nokuligcina lisesimweni esihle kunganciphisa ukusetshenziswa kukaphethiloli ngo-10% kuya ku-15% uma kuqhathaniswa nokusebenza ngepompo elingasebenzi kahle noma elonakele.

I-MKS Hydraulic inikeza ukwesekwa okuphelele ngemva kokuthenga okuhlanganisa izincwajana zokufaka ezinemininingwane, imibhalo yezobuchwepheshe, kanye nesevisi yamakhasimende ephendulayo ukusiza noma yimiphi imibuzo noma izinkinga ezingase zivele ngesikhathi sokufaka noma sokusebenza. Ithimba lethu lochwepheshe be-hydraulic linganikeza isiqondiso sokuthola izinkinga, lisize ekutholeni izimbangela eziyisisekelo zezinkinga zesistimu, futhi lincome izixazululo ezifanele ukuze kubuyiselwe ukusebenza okuphelele. Sikhwathi futhi sinohlu olubanzi lwezingxenye zokushintsha futhi sinikeza isiqinisekiso kuyo yonke imikhiqizo yethu, okukunikeza ukuzethemba kokuthi utshalo-mali lwakho luvikelwe umkhiqizi onamava amashumi eminyaka embonini ye-hydraulic.
