Description
Technical field
The utility model belongs to energy savings device technique field, particularly relates to a kind of piston power accumulator damping device and piston power accumulator.
Background technique
Accumulator is a kind of energy savings device in hydropneumatic system.It is in due course the energy conversion in system is that compression energy or potential energy store, and when system needs, again compression energy or potential energy is changed into the energy such as hydraulic pressure or air pressure and discharges, again mending supply system.When system instantaneous pressure increases, it can absorb this part energy, normal to ensure whole system pressure.
Existing piston power accumulator great majority do not have damping device, and small part has mechanical structure to cushion (piston adds outstanding terrace with edge, after running to end cap position thus reduce the object that liquid communication latus rectum reaches deceleration).For the piston power accumulator not having damping device, in large discharge working time, piston can clash into end cap, thus there is abnormal sound and the life-span of end cap and piston thereof is produced a very large impact (having potential safety hazard), but, although for have the piston power accumulator of mechanical cushioning device its than do not have will be good many, but when pressure reduction, flow are large, cushioning effect is not obvious, has had a strong impact on the working life of accumulator, adds maintenance and the replacement cost of equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of piston power accumulator damping device and piston power accumulator, with solve piston power accumulator but when pressure reduction, flow are large, cushioning effect is not obvious, has had a strong impact on the working life of accumulator, adds the maintenance of equipment and the problem of replacement cost.
In order to realize the purpose of this utility model, the utility model provides a kind of piston power accumulator damping device, comprise piston boss, groove and drain line, damper, return line, described piston boss is arranged at the left end of piston, its sidewall is provided with seal ring, described groove is arranged on oil end end cap, the external diameter of described seal ring equals the internal diameter of described groove, described drain line is connected with described groove, described drain line is connected with described return line by damper, and described return line is connected with shoe cream room.
Correspondingly, the utility model additionally provides a kind of piston power accumulator, and this kind of piston power accumulator uses piston power accumulator damping device described in the utility model.
The utility model, compared with prior art, the boss of piston adds sealing, directly cuts off oil circuit.On end cap, utilize damper to carry out throttling simultaneously, reduce fluid motion speed, reach the object of buffering, piston motion speed can be reduced effectively and rapidly.Stop the shock of piston and end cap, extend piston working life, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure, 1-drain line, 2-damper, 3-return line, 4-shoe cream room, 5-seal ring, 6-piston boss, 7-groove.
Embodiment
In order to make the purpose of this utility model, technological scheme and beneficial effect clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
As shown in Figure 1, the utility model provides a kind of piston power accumulator damping device, comprise piston boss, groove and drain line, damper, return line, described piston boss is arranged at the left end of piston, its sidewall is provided with seal ring, described groove is arranged on oil end end cap, the external diameter of described seal ring equals the internal diameter of described groove, described drain line is connected with described groove, described drain line is connected with described return line by damper, and described return line is connected with shoe cream room.
It should be noted that, when piston boss moves to oil end end cap groove time, due to the sealing of seal ring, the oil in the oil of shoe cream room and groove is cut off completely, the oil in groove is got back to shoe cream room by damper thus is reached the object of buffering.
In a preferred embodiment, described damper comprises: pressure transducer, Unidirectional solenoid valve, PLC, and described pressure transducer, Unidirectional solenoid valve are all connected with described PLC.Utilize pressure transducer and Unidirectional solenoid valve, automatically control, when the pressure in groove reaches predefined value, automatically open Unidirectional solenoid valve, oil is discharged, and further increases the effect of buffering.
Correspondingly, the utility model additionally provides a kind of piston power accumulator, and this kind of piston power accumulator uses above-mentioned piston power accumulator damping device.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
