Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.But this should be interpreted as that the scope of above-mentioned theme of the present utility model is only limitted to following embodiment.
Contrast Fig. 1, the utility model provides a kind of hydraulic pressure to rinse unit 16, this hydraulic pressure rinses unit 16 and comprises internal combustion engine 1, reducing gear 2, water pump 3, first safety valve 4, unloading electromagnetic valve 5, pressure regulator valve 6, check valve 7, first electromagnetic switch valve 8, hydraulic giant 9, water tank 10 etc., internal combustion engine 1 and reducing gear 2 are mechanically connected, and reducing gear 2 and water pump 3 are mechanically connected; Internal combustion engine 1 is as power, and internal combustion engine 1 drive deceleration mechanism 2 provides driving force for water pump 3.
This hydraulic pressure rinses the realization of Flow-rate adjustment by method adjustment water pump 3 flow of internal combustion engine 1 speed governing, reducing gear 2 speed governing of unit 16.Reducing gear 2 is made up of oil pump 13, motor 11, second safety valve 12, fuel tank 14, and oil pump 13, motor 11, second safety valve 12, fuel tank 14 are connected by oil pipe; Reducing gear 2 can adopt the forms such as gear reduction unit, quantitative oil pump 13+ fixed displacement motor 11, quantitative oil pump 13+ variable displacement motor 11, variable capacity oil pump 13+ variable displacement motor 11 to carry out speed governing.Reducing gear 2 adopts oil pump 13 CD-ROM drive motor 11 output torque and rotating speed to drive water pump 3, second safety valve 12 for the maximum pressure of the outlet of control oil pump 13 or overflow.
Water pump 3 is connected by water pipe with the first safety valve 4, unloading electromagnetic valve 5, pressure regulator valve 6, check valve 7, first electromagnetic switch valve 8, hydraulic giant 9 successively.Water pump 3 absorbs water from water tank 10; First safety valve 7 controls maximum pressure or the overflow of the outlet of water pump 3; Unloading electromagnetic valve 5 adopts two-position three way magnetic valve, and unloading electromagnetic valve 5 makes water pump 3 Low-pressure load discharge, and dead electricity water flowing case 10 during off-load, obtains electric logical pressure regulator valve 6 during operation; Pressure regulator valve 6 is for adjusting the water flow pressure thus the range of control hydraulic giant 9 that enter hydraulic giant 9; Check valve 7 ensures that unit independently supplies water, and the work of water pump 3 does not interfere with each other; First electromagnetic switch valve 7 is for controlling the break-make of hydraulic giant 9 current.
When water flushing unit adopts this hydraulic pressure of more than two covers to rinse unit 16, often overlapping check valve 7 rear end second electromagnetic switch valve 15 in parallel of hydraulic pressure flushing unit 16, when between hydraulic pressure flushing unit, the second electromagnetic switch valve 15 is in and disconnects position, two cover hydraulic pressure rinse cellular system and work alone, when being in on-position, for only having the operation of a hydraulic giant 9, the flushing water that the hydraulic pressure of hydraulic giant 9 of not working rinses unit collaborates to rinse unit to another hydraulic pressure by the second electromagnetic switch valve 15, thus makes the hydraulic giant 9 of work obtain larger flow.
Water tank 10 can be list cover hydraulic pressure and rinses the independent use of unit 16, and the hydraulic pressure flushing unit 16 that also can be two covers above is public.
Contrast Fig. 2, the utility model also can not adopt reducing gear 2, is directly connected with water pump 3 by internal combustion engine 1, and internal combustion engine 1 Direct driver water pump 3, by internal combustion engine 1 speed governing.
