Mapampu olumikizana amaika ma pampu awiri a giya pa shaft imodzi, kuwayendetsa kuchokera ku PTO imodzi. Mapampu a pistoni amagwiritsa ntchito ma pistoni obwerezabwereza mu kapangidwe ka swashplate, kupereka kusuntha kosasunthika kapena kosinthika kudzera mu kayendetsedwe ka makina kolondola.
Onse amagwiritsa ntchito ma hydraulics pamagalimoto, koma kugwiritsa ntchito kwawo sikungakhale kosiyana.
Momwe mapampu a tandem amagwirira ntchito
Kukonzekera kwa Tandem kumangiriza mapampu awiri odziyimira pawokha palimodzi, ndikugawana shaft yokhazikika. Pampu yoyamba imatha kutulutsa malita 82 pa 1000 RPM, pomwe yachiwiri imapereka malita 51 - kukupatsirani mabwalo awiri osiyana a hydraulic kuchokera kumalo okwera a PTO.
Pampu iliyonse imakhala ndi madoko ake olowera komanso otulutsira. Thamangani pamodzi kuti muzitha kuyenda kwambiri, kapena paokha pazochita zosiyanasiyana. Wowongolera amatha kugwiritsa ntchito mpope yayikulupo pokwezera, pomwe yaying'ono imagwiritsa ntchito zida zothandizira monga zonyamulira mchira kapena ma cranes.
Mapampu a giya mkati mwa tandem mayunitsi amagwira ntchito kudzera m'mano omwe amatsekera mafuta ndikukankhira panjira. Zosavuta, zodalirika, komanso zololera kuipitsidwa - zabwino pomanga malo ndi miyala yomwe imakhala yovuta.

Tekinoloje ya pampu ya piston
Mapampu a piston amagwira ntchito mosiyanasiyana. Ma pistoni angapo (kawirikawiri 6-9) amakwera motsutsana ndi swashplate yokhala ndi ngodya, ndikupanga kusamuka pamene akubwezera. Sinthani ngodya ya swashplate ndipo mumasinthasintha mayendedwe - china chake mapampu amagetsi sangachite.
Kusintha kosinthika kumeneku kumapangitsa mapampu a piston kukhala abwino kwa mapulogalamu omwe akufunika kuwongolera bwino. Pansi poyenda pamafunika mitengo yoyendera ndendende kuti musunge kulumikizana.
Ma Crane amafunikira kuyenda kosalala, kolingana. Mapampu a piston amapereka zonse popanda ma valve ovuta.
Mapampu a pistoni amatha kupanikizika kwambiri - mipiringidzo 350 yogwira ntchito yomwe ingawononge mapampu amagetsi. Magiya a Tandem amathamangira pa bar 210 kutayikira kwamkati kusanathe.
Kuthamanga kowonjezereka kumeneku kumatanthauza nkhosa zamphongo zothamanga kwambiri, mphamvu zonyamulira zamphamvu, ndi nthawi yofulumira yozungulira pa ntchito zolemetsa.

Zotsatira za machitidwe
Mapampu a Tandem amapambana popereka maulendo angapo kuchokera ku PTO imodzi. Kuthamanga mabwalo awiri kumapulumutsa malo, kumachepetsa zovuta, ndikudula nthawi yoyika. Kuthamanga kwa 190-210 bar kumagwira ntchito bwino kwambiri komanso ma hydraulic ambiri.
Kuchita bwino kumatsika pazipani zambiri, komabe. Mapampu a giya amawukhira mkati momwe kuthamanga kumakwera - momwe zimapangidwira. Pa bar 200, mukutaya 10-15% yakuyenda kwanu pakutuluka kwamkati. Ndibwino kuwongolera, kuwononga ntchito mosalekeza.
Mapampu a pistoni amasunga bwino pamlingo wawo wonse. Pa bar 300, akukankhirabe 95% mphamvu ya volumetric. Makina opindika amapangira mulingo wamagalimoto amanyamula 1500 RPM mosalekeza popanda kutenthedwa.
Mayendedwe ofunsira
Sankhani mapampu a tandem mukafuna ntchito ziwiri zosiyana zama hydraulic pazovuta zapakatikati. Dumphani zonyamula zidebe zakutsogolo ndi zokhazikika zakumbuyo zimapindula ndi mabwalo odziyimira pawokha. Ma Tipper okhala ndi ma cranes othandizira amapeza magwiridwe antchito apawiri popanda ma PTO apawiri.
Pampu za pistoni zimagwirizana ndi kuthamanga kwambiri, kusinthasintha koyenda. Kuyenda pansi, ma trailer a ejector, ndi magalimoto onyamula ma crane olemera amafunikira kuwongolera ndikuchita bwino ma pistoni okhawo omwe amapereka. Kukwera mtengo koyambirira kumabweza chifukwa chochepetsa kugwiritsa ntchito mafuta komanso nthawi yothamanga kwambiri.
Kunenepa kumafunikanso. Ma Tandem 82L/51L amalemera pafupifupi 28kg, pomwe mapampu ofanana a pistoni amabwera pa 19 kg pakusamuka kwa 105L. Kuchepetsa kulemera kumatanthawuza kuchuluka kwa malipiro - kofunika kwambiri kwa ogwira ntchito kuwonera kilogalamu iliyonse.
Dongosolo lanu la hydraulic limalamula kusankha. Fananizani ukadaulo wa pampu ndi zomwe mukufuna kugwiritsa ntchito, osati mwanjira ina.
