Accumulator is fixedly connected, and is ready for nitrogen charging；
S2, before nitrogen charging starts, be first added in the storage oil sump (28) of nitrogen pressurization system (24) on nitrogen charging car body (9) wear-resistant
Hydraulic oil 45L-55L, until in the middle part of oil ga(u)ge position；
S3, power on, the red button SA(43 in circuit system (23) on nitrogen charging car body (9)) it lights；
S4, the green button SB(46 is pressed in the short time), motor (20) direction of rotation is checked immediately, is positive clockwise
Really, if opposite direction rotates, red button SA(43 is pressed immediately), motor is closed, after readjusting power supply line, is restarted, until
Motor (20) is according to being rotated clockwise；
S5, after determining that motor rotates clockwise, operate nitrogen pressurization system (24) five minutes when uncharging, and look into
See whether the pilot operated directional control valve (19) of pressure charging system operates normally；
S6, adjustment electricity connect Voltage force table (15), and red pointer is transferred to required working pressure, can be stopped automatically when pressure reaches
Machine such as needs automatic pressurising, it is necessary to adjust electricity connect it is minimum using pressure value needed for green pointer in Voltage force table (15),
Red pointer is transferred to required maximal pressure force value, then circuit system (23) interior button switch is adjusted to automatic position by manual position
It sets；
S7, the exhaust valve (11) of Nitrogen filling vehicle upper end is connect by high-pressure rubber pipe with nitrogen cylinder (22), intake valve (10) and inflation
Tool (17) is fixedly connected, and inflatable tool (17) is fixedly connected with blower accumulator (21)；
S8, nitrogen cylinder (22) valve is slowly opened, slowly enters nitrogen in the Bidirectional supercharging device (7) of Nitrogen filling vehicle, passes through
Inner prop in Bidirectional supercharging device (7) does circularly-supercharged up and down, and until nitrogen charging pressure reaches predetermined value, Nitrogen filling vehicle pressurization stops automatically
Only；
S9, Nitrogen filling vehicle work finish, and close nitrogen cylinder (22) intake valve, then slowly open the Bidirectional supercharging device of Nitrogen filling vehicle
(7) the deflation screw plug in two deflation valve hand wheels and inflatable tool (17) in makes institute in Nitrogen filling vehicle until draining high pressure nitrogen
There is the pointer of pressure gauge to reset zero.
5. the vehicle-mounted method to wind power generating set accumulator nitrogen charging of one kind according to claim 5, it is characterised in that: institute
State running in S5 normally i.e. oil pressure gauge (5) pointer between 0-7MPa.
6. the vehicle-mounted method to wind power generating set accumulator nitrogen charging of one kind according to claim 5, it is characterised in that: institute
State the maximal pressure force value that S6 maximal pressure force value is lower than the setting of blower accumulator.
