Specific implementation mode
Fig. 2 and Fig. 3 schematically shows a kind of hydraulic closed multi-motor speed control of embodiment of the utility model
System processed.As shown in Figures 2 and 3, the hydraulic closed multi-motor speed control system include the first groups of motors, the second groups of motors,
Closed type hydraulic pump, slippage pump, fuel tank and control valve.
First groups of motors 1 is equipped with one or more motors, and the second groups of motors 6 also is provided with one or more motors.Slippage pump 3
Import be connected with fuel tank 7, the outlet of slippage pump 3 is connected with closed type hydraulic pump 2.Slippage pump 3 passes through two-way connecting pipe
It is connected with closed type hydraulic pump 2, the first benefit is respectively equipped in the two-way connecting pipe that slippage pump 3 is connected with closed type hydraulic pump 2
Fuel tap 4 and the second Fill valve 5.First Fill valve 4 and the second Fill valve 5 are check valve, the first Fill valve 4 and the second Fill valve 5
Import be connected respectively with slippage pump 3, the outlet of the first Fill valve 4 and the second Fill valve 5 is connected with closed type hydraulic pump 2 respectively
It is logical.When control valve 8 is located at it is upper when, for closed type hydraulic pump 2 by connecting pipe to 1 fuel feeding of the first groups of motors, closed type hydraulic pump 2 is logical
Connecting pipe and control valve 8 are crossed to 6 fuel feeding of the second groups of motors, the oil return of the first groups of motors 1 returns to enclosed liquid by connecting pipe
The oil return of press pump 2, the second groups of motors 6 returns to closed type hydraulic pump 2 by connecting pipe and control valve 8.When control valve 8 is located at bottom
When, by connecting pipe to 1 fuel feeding of the first groups of motors, the oil return of the first groups of motors 1 is returned to closed type hydraulic pump 2 by connecting pipe
Two hydraulic fluid ports of closed type hydraulic pump 2, the second groups of motors 6 are connected by control valve 8, and slippage pump 3 is also connect with control valve 8, are mended
Oil pump 3 is to 7 oil suction of fuel tank by connecting pipe control valve 8 to 6 repairing of the second groups of motors.
As shown in Fig. 2, when control valve 8 is in and switches to upper, closed type hydraulic pump 2 is by oil outlet to the first groups of motors
1 fuel feeding while multigroup hydraulic motor is driven to move to 6 fuel feeding of the second groups of motors by control valve 8, the first groups of motors 1 and second
The oil return of groups of motors 6 is returned directly to the oil inlet of closed type hydraulic pump 2 by control valve 8, successively iterative cycles, due to hydraulic pressure system
System, hydraulic system has a certain amount of leakage, while some flow takes hydraulic system, therefore repairing out of by cooling system
Pump 3 constantly to 7 oil suction of fuel tank by the first Fill valve 4 and the second Fill valve 5 to hydraulic system repairing.
As shown in figure 3, when control valve 8 switches to bottom, the second groups of motors 6 is completely cut through by control valve 8 is not involved in work
Make, but realize that two actuator ports are connected inside groups of motors by control valve 8, and is constantly inhaled to fuel tank 7 by slippage pump 3
Oil, to 6 repairing of the second groups of motors, is emptied when avoiding motor dragged inside motor by control valve 8.Closed type hydraulic pump 2 is by going out
For hydraulic fluid port only to 1 fuel feeding of the first groups of motors, 1 oil return of the first groups of motors is returned directly to the oil inlet of closed type hydraulic pump 2, this time follows repeatedly
Ring, since hydraulic system has a certain amount of leakage, while some flow takes hydraulic system out of by cooling system, therefore
Slippage pump 3 constantly to 7 oil suction of fuel tank by the first Fill valve 4, the second Fill valve 5 to hydraulic system repairing.
By the switching control of control valve 8, it can realize that control hydraulic system participates in the group number of the motor of work, due to liquid
