Description of reference numerals: 1-fuel tank, 2-oil absorption filter screen, 3-fuel sucking pipe, 4-electric-motor pump, 5-spraying tube, 6-relief valve, 7-solenoid directional control valve, the board-like Pilot operated check valve of 8-, 9-shift cylinder, 10-one-way valve, 11-high pressure filter, 12-pressure gauge, 13-the first hydraulic tube, 14-the second hydraulic tube, 15-pressure meter switch, 16-spill pipe.
Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the present invention mainly comprises fuel tank 1, and fuel tank 1 connects electric-motor pump 4 by fuel sucking pipe 3, is provided with oil absorption filter screen 2 in fuel sucking pipe 3, and oil absorption filter screen 2 is for to the interior hydraulic pressure oil filtration of fuel tank 1.
Electric-motor pump 4 connects one-way valve 10 by the first hydraulic tube 13, and one-way valve 10 connects solenoid directional control valve 7 by the second hydraulic tube 14, and solenoid directional control valve 7 is connected with board-like Pilot operated check valve 8, and board-like Pilot operated check valve 8 is connected with shift cylinder 9.
Described the first hydraulic tube 13 is provided with high pressure filter 11, for high pressure oil is filtered.
On described the second hydraulic tube 14, connect relief valve 6, relief valve 6 connects spraying tube 5 by spill pipe 16.
Bonding pressure table switch 15 on described the second hydraulic tube 14, pressure meter switch 15 rear end Bonding pressure tables 12.
Working principle of the present invention is: main transmission speed change is completed by the shift cylinder 9 of main shaft and the servo rotation of spindle motor, and speed change oil cylinder 9 is controlled by two four-way electromagnetic reversing valves 7, speed change gear is moved to left and the position on the right.During speed change, speed switch is adjusted to new position, pressed selector button, at this moment solenoid directional control valve 7 obtains electric, for speed change oil cylinder 9 cut-in pressure oil, speed change oil cylinder 9 carries out speed change according to switch given location, and speed change gear arrives behind the position of specifying, solenoid directional control valve 7 fuel cut-offs, speed change is complete.Pressure meter switch 15 is closed when adjusting the charge oil pressure of electric-motor pump and the protection pressure of relief valve 6, after adjustment, opens.
In the situation that solenoid directional control valve 7 obtains electric or power-off, electric-motor pump 4 fuel feeding, reach the limit of behind position at piston rod, and the pressure in system continues to raise, and when reaching the working pressure of relief valve 6, relief valve 6 is opened, and fluid accesses spraying tube, lubricated lathe.
