Control signal is transferred to motor 25, the rotation of control motor and stopping by 38；When motor 25 rotates, output shaft drives constant displacement pump
24 operate and continue to pump, and the water pumping direction of constant displacement pump 24 is constant, since method of adjustment is the electrodeless adjustment of dynamic persistently pumped,
Impact and noise are small, have evaded clump weight center of gravity and have adjusted bring a series of problems, have improved riding stability；Each solenoid valve is equal
For normally closed solenoid valve, oil circuit is connected in its lower end in non-applied state to the first reversal valve 231 with the second reversal valve 232, works as needs
When pumping from third water tank 213 to four water tanks 214, third solenoid valve 223 and the 4th solenoid valve 224 are opened, while second changes
It is powered to valve 232, such as Fig. 3, T1 mouthfuls of connection A1, T2 mouthfuls of connection A2, water flow successively pass through the 4th check valve 264,24 and of constant displacement pump
Third check valve 263 then flows into the 4th water tank 214 from P1；When needing to pump from the 4th water tank 214 to third water tank 213,
Other steps are identical, but the second reversal valve 232 powers off, and T1 mouthfuls of connection A2, T2 mouthfuls of connection A1, principle repeat no more at this time；When need
When pumping from the 4th water tank 214 to the second water tank 212, the second reversal valve 232 is closed, the first reversal valve 231 is connected, connects simultaneously
Lead to the 4th solenoid valve 224 and second solenoid valve 222, at this time B2 mouthfuls of connection P2, A2 mouthfuls of connection T2, water flow is successively from the 4th check valve
264, constant displacement pump 24 and the first check valve 261 flow to the second water tank 212 from second solenoid valve 222；When needing from the 4th water tank
When 214 water pumpings to the first water tank 211, other steps are same as above, but close the first reversal valve 231, at this time B2 mouthfuls of connection T2, A2 mouthfuls of companies
Logical P2, principle are same as above, and such scheme pumps the water in four water tanks of reasonable distribution by constant displacement pump 24, according to usage scenario
The position of centre of gravity for adjusting loading machine avoids loading machine generation rollover or front and back from toppling over；
