Below the working procedure of whole device is illustrated.
When the synchronous double speed device work of this fluid power, the drive unit band driven input shaft 7 such as motor drives internal box 2 to rotate, and utilizes working pump to be transported in internal box 2 working liquid body such as oil of depositing in outer casing 1 simultaneously.When internal box 2 has just started to rotate, owing to being loaded with load on output shaft 8, the bull gear 14 being fixedly connected with output shaft 8 is not rotated, planet wheel 11, reverse wheel 12, bucket wheel axle 10 follow internal box support 19 with bucket wheel 9 together with around output shaft 8 revolution; Meanwhile, bucket wheel 9 is at a high speed around bucket wheel axle 10 rotations.
Along with being rotated further of internal box 2, being accommodated in the inner liquid in casing 2 and acting on the circular liquid level of the interior formation of internal box 2 due to centrifugal force.When liquid level reaches predetermined altitude, liquid enters in the dished bucket wheel blade 22 of each bucket wheel.Enter liquid in bucket wheel blade 22 because the effect of centrifugal force forces the speed of autorotation of bucket wheel 9 to decline gradually until rotation stops, in this process, output shaft 8 rotating speeds rise gradually, final input shaft 7, internal box 2, planet wheel 11, bucket wheel 9, reverse wheel 12, bull gear 14 and output shaft 8 all rotate with identical speed, have realized the soft start of load.
More than can find out, the liquid level that is attached to the liquid on the internal surface of internal box 2 has determined the size of centrifugal force, and the size of centrifugal force further determined output shaft 8 can with input shaft 7 synchronous rotaries.Output shaft 8 is more tending towards synchronizeing with input shaft 7 rotation, and the slippage between output shaft 8 and input shaft 7 is less.
As shown in Figure 7, the synchronous double speed device of fluid power in the course of the work, electric current on the motor that current transformer 604 is measured reaches setting value, the outer casing 1 that for example, while being more than or equal to 120A (step 701) and Pt100 platinum thermoresistance 602 are measured or the temperature of internal box 2 interior liquid reach the value of setting, for example, while being more than or equal to 70 ℃ (step 703), signal can be passed to single-chip microcomputer 601, single-chip microcomputer 601 so by electromagnetic brake 15, control Brake drum 16(steps 702), Brake drum 16 starts engagement with sun gear 13, thereby sun gear 13 is braked, sun gear 13 is further delivered to reverse wheel 12 successively by braking force, planet wheel 11, bull gear 14, finally arrive output shaft 8, reduce output shaft rotating speed to increase moment of torsion, meanwhile, single-chip microcomputer 601 passes to solenoid valve 609 by signal, and solenoid valve 609 is opened, by fixedly scoop tube 18 and fuel-displaced pipeline 17, by the emptying rate of liquid of internal box, have so just reduced power loss.After electromagnetic brake 15 brakings, in fact a whole set of gear mechanism that participates in braking is exactly a conventional plane table thermoconductivity meter structure.
It should be pointed out that when electric motor starting, although initial current may surpass setting value,, 24V time delay relay 608 can control single chip computer 601, makes its delayed startup, and therefore, now single-chip microcomputer 601 does not start braking device and brakes.
When the outer casing 1 of measuring when Pt100 platinum thermoresistance 602 or the temperature of the liquid in internal box 2 are spent lower than 0 (step 703), signal can be passed to controller 601, controller 601 can start heating equipments 607 carry out fluid temperature heating (step 705).
Pressure in internal box 2 or temperature are during higher than predetermined value, and fusible plug 23 can be opened automatically, thereby the liquid in internal box 2 is emitted, to prevent that internal box 2 from damaging.
The present invention is after soft start finishes, and the output speed of output shaft 8 is identical near the input speed of input shaft 7, and this is first rotating speed of the synchronous double speed device output of this fluid power; After electromagnetic brake 15 work, Brake drum 16 reduces the rotating speed of output shaft 8 by sun gear 13, has increased moment of torsion, and rotating speed is now second rotating speed of this hydraulic self-synchronous device output, and therefore, this hydraulic self-synchronous device is called the synchronous double speed device of fluid power.
