Zopangidwa ku China zogulitsa zotentha kwambiri zopingasa zopingasa pampu zitatu za plunger

1. Pampu yothamanga kwambiri imagwiritsa ntchito mafuta okakamizika komanso kuziziritsa kuti zitsimikizire kuti nthawi yayitali yogwira ntchito yokhazikika yamagetsi;

2. Bokosi la crankshaft la mapeto a mphamvu limaponyedwa ndi chitsulo cha ductile, ndipo slide ya mutu wa mtanda imapangidwa ndi teknoloji ya manja a alloy ozizira, yomwe imakhala yosavala, phokoso lochepa komanso logwirizana kwambiri;

3. Kupera bwino kwa shaft ya zida ndi mphete ya giya, phokoso lotsika; Gwiritsani ntchito ndi NSK kuonetsetsa kuti ntchito yokhazikika;

4. Crankshaft amapangidwa ndi American muyezo 4340 mkulu khalidwe aloyi zitsulo, 100% chilema kudziwika chithandizo, forging chiŵerengero 4: 1, pambuyo kupulumuka, lonse nitriding mankhwala, poyerekeza chikhalidwe 42CrMo crankshaft, mphamvu kuchuluka ndi 20%;

5. Mutu wa pampu umagwiritsa ntchito kugawanika kwapamwamba kwambiri / madzi, zomwe zimachepetsa kulemera kwa mutu wa mpope ndipo zimakhala zosavuta kuziyika ndi kusokoneza pamalopo.

6. Plunger ndi tungsten carbide zakuthupi ndi kuuma kuposa HRA92, kulondola pamwamba kuposa 0.05Ra, kuwongoka ndi cylindricity zosakwana 0.01mm, zonse zimatsimikizira kuuma ndi kuvala kukana zimatsimikiziranso kukana kwa dzimbiri ndikusintha moyo wautumiki;

7. Tekinoloje yodziyimira yokha ya plunger imagwiritsidwa ntchito kuonetsetsa kuti plunger ikugogomezedwa mofanana ndipo moyo wautumiki wa chisindikizo umakulitsidwa kwambiri;

8. Bokosi losungiramo zinthu lili ndi katundu wotumizidwa kunja kwa V-mtundu kuti atsimikizire kuthamanga kwapamwamba kwa madzi othamanga kwambiri, moyo wautali;
