Abstract
The utility model relates to a low-pressure accumulator system for hydraulic system. The low-pressure accumulator system comprises an accumulator body, a piston is connected inside the accumulator body by the aid of springs, an oil nozzle is arranged in the lower end of the accumulator body, the springs are symmetrically and obliquely arranged inside the accumulator body, first sliding chutes are symmetrically formed in the inner side wall of the accumulator body, second sliding chutes are symmetrically arranged in the upper surface of the piston, and the first sliding chutes and the second sliding chutes are connected with the springs through sliding balls; a plurality of vertically arranged movable sealing rings are arranged in the inner wall of the piston and the inner wall of the accumulator body; diversion plates are symmetrically mounted on the inner bottom surface of the accumulator body and are separately located on two sides of the oil nozzle. The springs are obliquely arranged and slide in the sliding chutes to contract and extend, and buffering of the piston and energy supplement effect of the springs are improved; dynamic balance of oil liquid is improved by the arrangement of the diversion plates, and energy accumulating effect is further improved; by the adoption of the multi-layer movable sealing rings, sealing performance is improved.
Description
Technical field:
Model utility relates to hydraulic equipment field, particularly hydraulic accumulator.
Background technique:
Accumulator is a kind of energy savings device in hydropneumatic system.It is in due course and changes the energy in system into compression energy or potential energy stores, and in the time that system needs, again compression energy or potential energy is changed into the energy such as hydraulic pressure or air pressure and discharges, and again mends supply system.In the time that system instantaneous pressure increases, it can absorb this part energy, ensures that whole system pressure is normal.It can also and impact accumulator as fuel feeding and absorption system vibration in short-term.The shortcoming of traditional spring loaded accumulator adopts vertical spring, and its accumulation of energy poor effect, energy discharge not enough; Adopt individual layer seal ring, its sealing is not high.
Model utility content:
The applicant, for the above-mentioned shortcoming of conventional hydraulic accumulator, studies and improves, and a kind of low pressure accumulator structure for hydraulic system is provided, and it has simple in structure, the feature that operating flexibility is good.
In order to address the above problem, model utility adopts following scheme:
A kind of low pressure accumulator structure for hydraulic system, comprise accumulator body, in accumulator body, connect piston by spring, the lower end of accumulator body is with oil nozzle, in described accumulator body, symmetrical tilting device has described spring, the madial wall symmetry of accumulator body is with the first chute, and the upper surface of described piston is arranged with the second chute, between the first chute and the second chute, is connected described spring respectively by sliding ball;
Between the inwall of described piston and accumulator body, device has multiple dynamic seal rings setting up and down; The inner bottom surface of described accumulator body is symmetrically installed with guide plate, and guide plate divides and occupy described oil nozzle both sides.
Further improvement as technique scheme:
Described guide plate is with wavy shaped configuration.
The technique effect of model utility is:
The more original spring loaded accumulator of the utility model, being obliquely installed and sliding to realize in chute and shrink and extend of spring, has improved cushioning effect and energy supplement function; Owing to having increased waveform guide plate, guide plate has improved the dynamic balancing of fluid, further improves accumulation of energy effect; Adopt multilayer dynamic seal ring, improved sealability.
Brief description of the drawings:
Fig. 1 is main sectional view of the present utility model.
In figure: 1, accumulator body; 11, the first chute; 12, oil nozzle; 2, spring; 3, piston; 31, the second chute; 4, dynamic seal ring; 5, fluid; 6, guide plate; 7, slide ball.
Embodiment:
Below in conjunction with accompanying drawing, the embodiment of model utility is described further.
As shown in Figure 1, the low pressure accumulator structure for hydraulic system of the present embodiment, comprise accumulator body 1, in accumulator body 1, connect piston 3 by spring 2, the lower end of accumulator body 1 is with oil nozzle 12, and the interior symmetrical tilting device of accumulator body 1 has spring 2, and the madial wall symmetry of accumulator body 1 is with the first chute 11, the upper surface of piston 3 is arranged with between the second chute 31, the first chutes 11 and the second chute 31 respectively by sliding ball 7 linking springs 2;
Between the inwall of piston 3 and accumulator body 1, device has multiple dynamic seal rings 4 setting up and down; The inner bottom surface of accumulator body 1 is symmetrically installed with guide plate 6, and 6 points of guide plates occupy oil nozzle 12 both sides, and guide plate 6 is with wavy shaped configuration.
The more original spring loaded accumulator of the utility model, being obliquely installed and sliding to realize in chute and shrink and extend of spring 2, has improved buffering and the energy supplement effect of piston; Owing to having increased waveform guide plate 6, guide plate 6 has improved the dynamic balancing of fluid 5, further improves accumulation of energy effect; Adopt multilayer dynamic seal ring 4, improved sealability.
