Explain in the face of the working procedure of whole device down.
When the synchronous double speed device of this fluid power was worked, the drive device drives input shaft 7 such as motor drove internal box 2 and rotates, and the working liquid body such as oil that will deposit in simultaneously in the outer casing 1 utilizes working pump to be transported in the internal box 2.When internal box 2 has just begun to rotate, owing to be loaded with load on the output shaft 8, the bull gear 14 that is fixedly connected with output shaft 8 is not rotated, planet wheel 11, reverse wheel 12, bucket wheel axle 10 and bucket wheel 9 are followed internal box support 19 together around output shaft 8 revolution; Simultaneously, bucket wheel 9 is at a high speed around bucket wheel axle 10 rotations.
Along with being rotated further of internal box 2, be contained in the liquid in the internal box 2 because action of centrifugal force forms circular liquid level in internal box 2.When liquid level reached predetermined altitude, liquid got in the dished bucket wheel blade 22 of each bucket wheel.The liquid that gets in the bucket wheel blade 22 stops until rotation owing to action of centrifugal force forces the speed of autorotation of bucket wheel 9 to descend gradually; 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.
Can find out that more than 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 can the size of centrifugal force have determined further output shaft 8 rotate synchronously with input shaft 7.Output shaft 8 is tending towards rotating synchronously with input shaft 7 more, and the slippage between output shaft 8 and the input shaft 7 is more little.
As shown in Figure 7; The synchronous double speed device of fluid power in the course of the work, the electric current on the motor that current transformer 604 is measured reaches setting value, the temperature of liquid reaches the value of setting in outer casing 1 that (step 701) and Pt100 platinum thermoresistance 602 are measured during for example more than or equal to 120A or the internal box 2; During for example more than or equal to 70 ℃ (step 703); Can signal be passed to single-chip microcomputer 601, single-chip microcomputer 601 and then through electromagnetic brake 15 control brake wheel 16 (steps 702), Brake drum 16 begins engagement with sun gear 13; Thereby sun gear 13 is braked; Sun gear 13 further is delivered to reverse wheel 12, planet wheel 11, bull gear 14 with braking force successively, arrives output shaft 8 at last, reduces the output shaft rotating speed to increase moment of torsion; Simultaneously, single-chip microcomputer 601 passes to solenoid valve 609 with signal, and solenoid valve 609 is opened, through fixedly scoop tube 18 and fuel-displaced pipeline 17 have so just reduced power loss with the liquid emptying of internal box.After electromagnetic brake 15 brakings, in fact a whole set of gear mechanism of participating in braking is exactly a plane table thermoconductivity meter structure commonly used.
Should be pointed out that when electric motor starting, though initial current possibly surpass setting value,, 24V time delay relay 608 can control single chip computer 601, makes its delayed startup, and therefore, single-chip microcomputer 601 did not start braking device and braked this moment.
The outer casing of measuring when Pt100 platinum thermoresistance 602 1 or the temperature of the liquid internal box 2 in are lower than 0 when spending (step 703), can signal be passed to controller 601, and controller 601 can start heating equipments 607 and carry out fluid temperature and heat (step 705).
When the pressure in the internal box 2 or temperature were higher than predetermined value, fusible plug 23 can be opened automatically, thereby the liquid in the internal box 2 are emitted, and damaged to prevent internal box 2.
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 makes the rotating speed of output shaft 8 reduce through sun gear 13, has increased moment of torsion, and the rotating speed of this moment is 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.
