Falanqaynta sababta nozzle-ka cirbaduhu ugu dhegay cirbadaha (qaybta 2)

1.2 Qallafsanaanta waalka irbadda leh lambarka shaambada birta ee HHM waa Ra0.03 Rt0.34, iyo engegnaanta dusha sare waa 60.4HRC～60.7HRC; Waalka irbadda leh nambarka shaambada birta HD waa Ra0.02, Rt0.37, iyo engegnaanta dusha sare waa 62.3HRC. Qallafsanaanta iyo adkaanta labada irbadood ee loo soo gudbiyey si loo baaro dhamaantood waxay buuxiyaan shuruudaha naqshadeynta. Ka dib markii sanka la gooyey, godka hoose ee qallafsanaanta ayaa la qiyaasay. Shuruudaha qalafsanaanta daloolka gudaha ee biibiile waxay ahayd 0.05Rt0.8. Valve Ra0.07-1.16, Rt0.82-1.79. Daloollada gudaha ee labada nozzles ee loo soo gudbiyay kormeerka ma buuxin shuruudaha naqshadeynta.
