ZQYM-8320 Common Rail Diesel Fuel vp44 Injection Pump Test Bench
Kuchita kwa injini ya dizilo kumadalira kwambiri kusintha kwapope kwa jekeseni wamafuta. Ngakhale benchi yoyeserera pampu yamafuta ili ndi zofunikira zaukadaulo kuti zitsimikizire kulondola kwa kusintha kwa pampu ya jekeseni yamafuta, ngati kugwiritsa ntchito ndi kukonza sikunachitike bwino, kuwongolera bwino kwa mpope wa jekeseni sikungatsimikizidwe.
1 Zofunikira zaukadaulo za benchi yoyeserera pampu yamafuta
(1) Kulakwitsa kwakukulu kwa benchi yoyesera sikuyenera kupitirira ± 10' pamalo aliwonse, ndipo sikelo iyenera kukhala yomveka bwino.
(2) Kusinthasintha kwachangu nthawi yomweyo mkati mwa kusintha kulikonse kwa shaft yotuluka pa benchi yoyesera sikuyenera kupitirira 1% ya liwiro la mayeso pamene liwiro loyezera la disc yotulutsa shaft ndi> 600 r / min; pamene liwiro liri ≤ 600 r / min, kusinthasintha kwachangu nthawi yomweyo sikudzakhala kuposa 6 r / min.
(3) Njira yowerengera ya benchi yoyesera iyenera kukhala yolondola komanso yodziwika bwino, ndipo imatha kuwerengera nthawi 100 mpaka 1000 mu gear iliyonse, ndipo cholakwika chovomerezeka chowerengera dongosolo lonse ndi nthawi imodzi.
(4) Silinda yoyezera mafuta ya benchi yoyesera iyenera kukhala ndi sikelo yomveka bwino komanso yolondola, sikelo yocheperako sikuyenera kukhala yayikulu kuposa 1% ya sikelo yonse, ndipo cholakwika cha sikelo chiyenera kukhala mkati mwa 0,5% ya sikelo yonse.
(5) Kuthamanga kwa mafuta pa benchi yoyesera kuyenera kusinthidwa ndikukhazikika. Pa liwiro lovomerezeka, pamene malo onse atsekedwa, kupanikizika kwakukulu kuyenera kufika: dera la mafuta otsika ≥ 0.4 MPa; mafuta othamanga kwambiri ≥ 34 MPa.
(6) magawo a mkulu-anzanu mafuta chitoliro kwa debugging mu mzere mafuta jekeseni mpope: kutalika × m'mimba mwake × m'mimba mwake mkati, amene 600 mm × 6 mm × 2 mamilimita ntchito debugging pampu jekeseni mafuta amene kuzungulira mafuta voliyumu yopereka sichidutsa 300 mm 3; 800 mm × 8 mm × 39 mamilimita ntchito kutumidwa kwa mapampu jekeseni mafuta ndi ozungulira mafuta ochuluka kuposa 300 mm; 800 mm × 6 mm × 2 mamilimita ntchito kutumidwa kwa anagawira mapampu jekeseni mafuta.
(7) Injector wamba wamafuta osankhidwa ndi benchi yoyesera angagwiritsidwe ntchito kupereka mafuta osapitilira 300 mm3 pa kuzungulira. Liwiro la mpope jekeseni mafuta ndi 1000 r/mphindi, mafuta giya ndodo anakonza pa udindo wa 103 mm3 mkombero. Nthawi 1000 pampu Pamene voliyumu ya mafuta ili pamtunda wa 102-103 cm3, kuthamanga kwa valve ya singano ndi 17.5 MPa.
(8) Pampopi yojambulira mafuta yomwe ikugwiritsidwa ntchito, chifukwa cha kuchepa kwa magwiridwe antchito, jekeseni yamafuta yokonzedwa yagalimoto yoyambirira iyenera kugwiritsidwa ntchito poyesa pampu yamafuta. Mwanjira imeneyi, injiniyo imatha kutsimikiziridwa kuti ikugwira ntchito pansi pa mafuta abwinobwino komanso ofananirako kuyambira pachiyambi mpaka pomwe jekeseni wamafuta asinthidwa. Ngati jekeseni wamba wamafuta agwiritsidwa ntchito pochotsa zolakwika, ndipo injiniyo imagwira ntchito ndi jekeseni wamafuta omwe si wamba, singagwire ntchito ndi kufanana kofunikira kwamafuta, motero kutaya tanthauzo la kusokoneza pampu ya jekeseni.
(9) Kutentha kwa chipinda choyesera kumakhudza kwambiri momwe mafuta amaperekera pampu ya jekeseni wamafuta, chifukwa kuchuluka kwa mafuta a dizilo kumasintha ndi kutentha, ndipo mafuta omwe amaperekedwa m'mabuku aukadaulo amatanthauza kutentha kwachipinda. pa 20 ℃. Kupereka mafuta. Kuyesedwa kwatsimikizira kuti kutentha kumatsika kuchokera ku 40 ° C mpaka 6 ° C, mafuta amatha kuwonjezeka ndi 20% mpaka 40%, ndipo ngati kutentha kumatsikiranso, kukana kwa chitoliro cha mafuta othamanga kwambiri ndi jekeseni. idzawonjezeka kwambiri chifukwa cha kuwonjezeka kwakukulu kwa mlingo wa mafuta a dizilo , mafuta a mafuta adzachepa m'malo mwake. Kuti musinthe momwe mafuta amaperekera molondola, kutentha kwa msonkhano woyeserera kuyenera kusungidwa kutentha kwapakati pa 15-20 ° C, makamaka pampu yojambulira mafuta othamanga kwambiri imakhudzidwa kwambiri ndi kusintha kwa kutentha kwamafuta.
