Ifanele itshintshwe nini ipompo ye-hydraulic enomsindo endaweni yokulungiswa?
Ipompo ye-hydraulic enomsindo kufuneka itshintshwe endaweni yokuba ilungiswe xa ingxolo ibangelwa kukuguguleka kwe-vane-tip okungaphaya komda wenkonzo yomenzi (ngesiqhelo i-0.05 mm clearance kuyilo lwe-Vickers VQ intra-vane), xa ukusilela kwebheri kuqhubele phambili ukuya kwinqanaba apho ubushushu becala bungaphezulu kwama-50 degrees C ngaphezulu kwe-ambient, xa ingxolo ihamba nomoya obonakalayo kwi-reservoir, okanye xa ipompo yakhiwe kwakhona ngaphezulu kwesibini kwaye ingxolo ibuya ngaphakathi kobomi benkonzo elinganisiweyo. I-spec yokuthenga yokutshintshwa yipompo ye-Vickers VQ series intra-vane, efumaneka kwi-20VQ, 25VQ, 35VQ, 45VQ, 2520VQ, 3520VQ, 3525VQ, 4520VQ, 4525VQ, kunye ne-4535VQ displacements, kunye noyilo lwe-12-vane lokujikeleza okuphantsi, ukulinganisela kwe-hydraulic ubomi benkonzo ende, kunye ne-cartridge ezimeleyo yokukhonza ngaphandle kokususa ipompo kwindawo yokuyifaka.
Indlela iVicks Hydraulic exhasa ngayo ukuxilongwa kwengxolo yeHydraulic Pump
Kwingcali yokulungisa, umyili wenkqubo ye-hydraulic, okanye igosa lokuthenga elichaza indawo yepompo ye-vane endaweni yesicelo esinomsindo, inkqubo yokuthenga iyawa ibe ngamaxwebhu amathathu: aIinkcukacha zemveliso yochungechunge lwe-VQ(Ukususwa kwe-12 okugubungela i-10 ukuya kwi-180 cc/rev), aifomu yokuxilongwa kwengxolo(itshathi yokuxilonga enemigca eli-12 eneempawu, unobangela, uvavanyo lokuqinisekisa, kunye nolungiso), kunye neisicelo sokuxilonga iimpawu zengxolo kuVicks(indlela ye-imeyile yokuthumela iimpawu zengxolo kwinjineli yeVicks kwisicelo esithile sepompo).Udidi lweMpompo yeHydraulic yeVicksibandakanya uthotho lwe-VQ, uthotho lwe-T6/T7 Denison, uthotho lwe-V10/V20 Vickers, kunye nothotho lwe-ABT servo pump.indlela yoqhagamshelwanoUkuxilongwa kwengxolo yiWhatsApp okanye i-imeyile yeqela leenjineli zeVicks, enexesha lokuphendula iiyure ezingama-24 kwizicelo ezininzi.
