The above-mentioned hydraulic pressure that is used for wheel tooth type crusher is adjusted insurance system, wherein, also connects a pressure sensor and a Pressure gauge on the described a pair of accumulator respectively.
The above-mentioned hydraulic pressure that is used for wheel tooth type crusher is adjusted insurance system, and wherein, described solenoid directional control valve is a three position four-way electromagnetic valve.
The above-mentioned hydraulic pressure that is used for wheel tooth type crusher is adjusted insurance system, and wherein, described pressure release overflow valve is connected in the fuel tank through a stop valve.
The above-mentioned hydraulic pressure that is used for wheel tooth type crusher is transferred the whole system of insurance, wherein, also connects a filter between described first check valve and the hydraulic pumping unit.
The above-mentioned hydraulic pressure that is used for wheel tooth type crusher is transferred the whole system of insurance, wherein, also is provided with electric heater, liquid level liquid thermometer, air cleaner and oil suction filter on the described fuel tank.
Adjust the technical scheme of insurance system owing to adopted the hydraulic pressure that is used for wheel tooth type crusher of the present utility model, it has hydraulic pressure adjustment and insurance function, can not only realize the adjustment of discharge gate by the hydraulic system principle, utilize the synchronous translation of pair of hydraulic cylinders realization activity roll shaft, can realize " crossing iron " insurance by pressure release overflow valve and accumulator again, it adjusts lowering and work-saving, easy and safe to operate, the crushing teeth wearing and tearing evenly, long service life is a kind of adjustment and insurance institution of desirable kibbler roll.
Description of drawings
Fig. 1 adjusts the structural representation of insurance system for the hydraulic pressure that is used for wheel tooth type crusher of the present utility model.
The specific embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 and Fig. 2, a kind of hydraulic pressure that is used for wheel tooth type crusher of the present utility model is adjusted insurance system, comprise a fuel tank 1, a hydraulic pumping unit, one first check valve 3, an overflow valve 4, solenoid directional control valve 5, one second check valve 6, pair of hydraulic cylinders 7, a pair of pressure release overflow valve 8 and an a pair of accumulator 9, wherein, fuel tank 1 is provided with electric heater 11, liquid level liquid thermometer 12, air cleaner 13 and oil suction filter 14.
Hydraulic pumping unit comprises motor 21 and gear pump 22; Solenoid directional control valve 5 is a three position four-way electromagnetic valve.
Connect hydraulic pumping unit, first check valve 3 and solenoid directional control valve 5 successively by pipeline on the fuel tank 1, an outlet of this solenoid directional control valve 5 connects the ante-chamber of pair of hydraulic cylinders 7 respectively by pipeline, another exports through connect the back cavity and a pair of accumulator 9 of a pair of pressure release overflow valve 8, pair of hydraulic cylinders 7 behind second check valve 6 respectively by pipeline; The outlet of first check valve 3 connects overflow valve 4 and is connected in the fuel tank 1 by pipeline.
Pressure release overflow valve 8 also is connected in the fuel tank 1 through a stop valve 80.
Also connect a pressure sensor 91 and a Pressure gauge 92 on a pair of accumulator 9 respectively.
Also connect a filter 15 between first unidirectional 3 valves and the hydraulic pumping unit.
It is to be power with the oil of working that a kind of hydraulic pressure that is used for wheel tooth type crusher of the present utility model is adjusted insurance system, the hydraulic pressure adjustment of disintegrating machine discharge gate is realized by the hydraulic pumping unit DFF Direct Fuel Feed, and " crossing iron " insurance is to realize by accumulator 9 that charges into certain pressure nitrogen in advance and pressure release overflow valve 8.Its operation principle is:
Hydraulic pumping unit starts, and work oil enters solenoid directional control valve 5 by first check valve 3, and the work oil of making enters the hydraulic system of being made up of second check valve 6, Pressure gauge 92, accumulator 9 and pressure release overflow valve 8, and enters the back cavity of hydraulic cylinder 7.During the disintegrating machine operate as normal, the size of crushing force is mainly adjusted by the size that changes working oil pressure.According to the material condition, adjust the force value of overflow valve 4 by needed crushing force size, close second check valve 6 after reaching definite value, system is in packing state, hydraulic pumping unit just can quit work, and when need be the gap between stationary roller shaft and the movable roll shaft by greatly when ditty is whole, the work oil of being discharged by hydraulic pumping unit 2 enters the back cavity of hydraulic cylinder 7, make the piston rod of hydraulic cylinder 7 drive the axially preceding translation of movable roll, with the gap smaller between two roll shafts.When need be the gap between two roll shafts by little during to big adjustment, the work oil of being discharged by hydraulic pumping unit enters the ante-chamber of hydraulic cylinder 7, makes the piston rod of hydraulic cylinder 7 drive axially back translation of movable roll, and the gap between two roll shafts is become big.When non-broken material enters crusher chamber, movable roll is axially passed the back, the work oil of hydraulic cylinder 7 back cavities is through entering accumulator 9 and pressure release overflow valve 8 fast, the controlled pressure of releasing makes the work oil spill stream in the hydraulic cylinder 7, gap between two roll shafts is widened fast, make non-broken material discharge crusher chamber, thereby played the buffering safety effect, after non-broken material is discharged crusher chamber, promptly eliminating the back at abnormal pressure raises controlled pressure by the pressure of accumulator 9 and pressure release overflow valve 8 cuts out, and make the pressure of work oil in the hydraulic cylinder 7 return to set pressure, recover normal operating conditions.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
