Definitions
- the invention is known as a method and control system of the hydraulic pulse generators, which are used as equipment for the hydraulic consumers or as independent systems for puddles, crushing the oversizes in the build-up or for drying out paint from the ladles.
- Control methods and systems are known in which the control of the striking element of the hydraulic pulse generator takes place with the aid of a control slide built into the generator body, which is controlled by the striking element, with or kinematic connection to it.
- the known constructive solutions differ in the control, the positioning of the sole and control element as well as the type of mutual interaction.
- these systems have the disadvantage that the functional parameters are difficult to adapt to the different working conditions, that the cleanliness of the standardized mass required by the operational necessities is more difficult to achieve, the control systems have long reaction times, which results in limited strike frequencies.
- the method, according to the invention eliminates these disadvantages in that, in order to make it easier to adapt the functional parameters to the various working conditions, the control of the impact element of the pulse generator is no longer dependent on the position of the racket in its body, but on the pressures which in the hydraulic circuits of the generator, pressures that are only caused by the intermediate and limit states of the energy generator of the system and an energy storage element.
- the control position is implemented using binary logic e-hydraulic elements, controlled by the output signals of a hydraulic processor, which analyzes the signals from the memory and energy generator and, depending on their status, controls the operating fluid to the racket, preferably i move it with the energy storage moving upwards on the opposite side of the club and moving it down while releasing the stored energy to which the energy given by the energy generator of the circle is added.
- the Hethods uses a hit 1 for the realization of the useful work, which makes a movement up and down inside a cylinder 2.
- the lifting and lowering forces of the striker 1 are realized by the difference of some working surfaces a, b and c, the striker 1 and the pressures within the cylinder 2, served by the surfaces a, b and c.
- the phenomenon of hay cyclical in character and consists of a lifting and a lowering phase.
- the liquid is introduced under pressure into the area served by the surface a by a pump 3 by means of a logic element 4.
- the liquid from the area served by the curses c is fed into a storage 5 and the liquid from the area served by the curses b is conducted to a container 6 by means of a logic element 7.
- a member d served by the surface c is subjected to the pressure from the accumulator 5 and the pump 3, and by opening the logic element 10 and closing the logic element 7, a area e served by the area b is exposed to the effect of the pressure from the accumulator 5 and the pump 3.
- a chamber f operated by the area a of the racket 1, is connected to the container 6 of the system by means of a logic element 11. Since in this phase from chamber f, served by area a, a larger one Funding anga is discharged, a low-pressure safety device connected to the back loop of the feeder is used.
- the opening and closing sequence of the logic elements 4, 7, 8, 10 and 11 is analyzed in a hydraulic processor depending on the determined pressure conditions from the accumulator 5 and the pump 3.
- All logic elements 4, 7, 8, 10 and 11 and the processor 13 are incubated in one body 14, which is connected to another body 15 of the generator, which is not shown, the connection between them through some channels g, h and i, which are located in the two bodies 14 and 15, is produced.
- the memory 5 and 12 are also connected, and the connection between the pump 3 and the container 6 of the supporting device is made through a few lines 16 and 17 attached.
- a working tool 18 is mounted, through which the impacts generated by the racket 1 are conducted to the working radius.
- Industrial applications Possible invention can be used with good results for the equipment of the hydraulic walkers or as an independent system for carrying out various construction work such as pile ramming and removing the structures, crushing the oversizes in mining.
- the present invention can also be sent to the foundry for various work such as Knocking out slag from the ladle, breaking the furnace, etc.
