Breath feeds back to controller 8；Controller 8 continuously sends out reduction speed command, until the fuel feeding frequency and automatically controlled spray of reciprocal oil feed pump 4
The oil spout frequency of oily device 11 matches, then controller 8, which issues, maintains present speed to instruct to straight line electric drive 7.
6 unusual service condition of operating condition: it when causing the fuel pressure moment inside voltage-stablizer 9 sharply to increase due to certain failure, supplies
Oily device have 3 grades gradually triggering measure solve the problems, such as.1st level security measure: pressure sensor 14C is anti-by abnormal pressure information
It feeds controller 8, the fuel pressure that controller 8 is measured according to pressure sensor 14A and pressure sensor 14B judges left fuel feeding
Which fuel supply chamber is in oil-absorbing process in chamber A and right fuel supply chamber B, if left fuel supply chamber A is in oil-absorbing process, controller 8 is sent out
After reversed open command gives check valve 3B, check valve 3B reversely to open out, the high pressure fuel inside voltage-stablizer 9 is flowed through check valve 3B
Enter into left fuel supply chamber A；It equally is in oil-absorbing process if it is right fuel supply chamber B, then reversed open check valve 3D, in voltage-stablizer 9
The high pressure fuel in portion is flowed into right fuel supply chamber B through check valve 3D.2nd level security measure: if check valve 3B or check valve 3D
After reversed unlatching, the fuel pressure inside voltage-stablizer 9 is still abnormal high, and the sending fuel cut-off of controller 8 is instructed drives to straight-line electric
Dynamic device 7, stops reciprocal 4 fuel feeding of oil feed pump.3rd level safety measure: reversed open command is simultaneously emitted by check valve 3B and unidirectional
Valve 3D makes the high pressure fuel inside voltage-stablizer 9 while quickly entering inside left fuel supply chamber A and right fuel supply chamber B, to make pressure stabilizing
Fuel pressure inside device 9 is reduced in safe range.When the failure of electric-controlled fuel injector 11, the high compression ignition of big flow is sprayed
Oil, the fuel pressure moment inside voltage-stablizer 9 drastically reduce, and abnormal pressure information is fed back to controller by pressure sensor 14C
8, controller 8 issues out code to excess-flow valve 10, realizes oil-break function, prevents the high pressure fuel of big flow from spraying into and starts
