(5) [igniting] switch, is opened, [weak fire is adjusted] valve when [igniting] indicator light is bright, is opened, when [boiler flame] indicator light is bright,
Combustor is lighted a fire successfully, is closed [ignition switch], and adjustment [weak fire is adjusted] valve and [fuel oil adjusting] valve keep [fuel pressure] table
Show numerical value in 0.7~2.0MPa；
(6), combustor opens [moderate heat adjusting] valve, when [boiler flame] indicator light is bright, combustor after small fire state continues 30s
It is burnt successfully with high fire state, and adjusts [weak fire is adjusted] valve and [fuel oil adjusting] valve, [fuel pressure] table is kept to show numerical value
In 0.7~2.0MPa；
If (7), boiler export is too high or too low for temperature, [fuel oil adjusting], [weak fire is adjusted] and [moderate heat adjusting] valve are adjusted in time
Aperture；
3, it shuts down
3.1, boiler flameout
(1), [moderate heat adjusting] valve is closed, combustor stops high fire burning, and enters small fire state and burn；
(2), [weak fire is adjusted] valve is closed, combustor stops small fire burning, and [boiler flame] indicator light off, adjusts [fuel oil adjusting]
Valve, so that [fuel pressure] table numerical value shows 0.5MPa or less；
(3), when boiler export temperature≤80 DEG C, [blower] and [radiator] switch is closed, blower shuts down,
Entire hydraulic system stops working；
(4) [hand throttle], is restored into raw bits, [engine speed indicator] shows minimum value；
(5), [power supply] switch is closed, [power supply] indicator light off, and whole operation system is out of service；
3.2, diesel motor flameout
(1) the throttle for, adjusting engine, so that engine speed is reduced to idling mode；
(2), the mounting of clutch is extractd, to stop the operating of three-cylinder plunger pump and hydraulic system；
3.3, the other items shut down
(1), after high pressure cold wash or heating well-flushing construction, head valve is first closed, pressure in pipeline is shed；
(2), dismantle into well casing road, and be clamped on pipe support；
(3) infusion sebific duct, is disassembled, is placed on framework；
(4) after, returning to garage, the power switch of storage battery is closed.
