Abstract
The utility model relates to and discloses a kind of pressure filter oil-leakage-prevention seal ring, it comprises foundation ring and guard ring, wherein said foundation ring and described guard ring is integrally manufactured forms and coaxially arranged, described guard ring diameter is less than described foundation ring diameter and has a cavity portion between described guard ring and described foundation ring, the top of described cavity portion arranges through hole on, described cavity portion a lower through-hole is set below.The pressure filter oil-leakage-prevention seal ring that the utility model provides, owing to arranging one guard ring on top, foundation ring, oil leakage phenomenon is there is when can prevent pressure filter piston rod from working, conventional seal ring is utilized with the past, every day, leakage of oil was about 5L, within 1 year, calculated with 300 days, hydraulic oil can be saved every year and reach 1500L, greatly reduce cost of production.
Description
Technical field
The utility model relates to seal ring technical field, particularly relates to a kind of pressure filter oil-leakage-prevention seal ring.
Background technique
At present, existing pressure filter is through using for a long time, its main working parts piston rod surface smoothness reduces, the phenomenon of leakage of oil will be there is in this when causing piston rod to work, miss 5 liters of hydraulic oil about every day, although this problem can be solved by the mode often changing conventional seal ring, but can oil leakage phenomenon be alleviated in the short time after changing careful seal, the root problem of leakage of oil still can not be solved from the angle of equipment long-time running, in addition, this problem can also be solved by the mode changing piston rod, but cost intensive, therefore, a kind of pressure filter oil-leakage-prevention seal ring is provided to have very important significance.
Model utility content
The utility model cannot solve the technical problem of oil leakage phenomenon in order to the conventional seal ring solving prior art and exist, and provides a kind of pressure filter seepage-proof oil seal ring occurring oil leakage phenomenon when can prevent piston rod from working.
For achieving the above object, the technological scheme that the utility model adopts is as follows:
A kind of pressure filter oil-leakage-prevention seal ring, it comprises foundation ring and guard ring, wherein said foundation ring and described guard ring is integrally manufactured forms and coaxially arranged, described guard ring diameter is less than described foundation ring diameter and has a cavity portion between described guard ring and described foundation ring, the top of described cavity portion arranges through hole on, described cavity portion a lower through-hole is set below.
The pressure filter oil-leakage-prevention seal ring that the utility model provides, owing to arranging one guard ring on top, foundation ring, oil leakage phenomenon is there is when can prevent pressure filter piston rod from working, conventional seal ring is utilized with the past, every day, leakage of oil was about 5L, within 1 year, calculated with 300 days, hydraulic oil can be saved every year and reach 1500L, greatly reduce cost of production.
Accompanying drawing explanation
Fig. 1 is the utility model oil-leakage-prevention seal ring plan view;
Fig. 2 is the utility model oil-leakage-prevention seal ring left view;
In figure: 1-foundation ring; 2-guard ring; The upper through hole of 3-; 4-lower through-hole; 5-cavity portion.
Embodiment
As shown in Figure 1-2, pressure filter oil-leakage-prevention seal ring of the present utility model, comprise foundation ring 1 and guard ring 2, wherein foundation ring 1 and guard ring 2 are integrally manufactured forms and coaxially arranged, guard ring 2 diameter is less than foundation ring 1 diameter and has a cavity portion 5 between guard ring 2 and foundation ring 1, the top of cavity portion 5 arranges through hole 3 on, cavity portion 5 a lower through-hole 4 is set below.
During use, upper through hole 3 is air hole, contacts all the time with external environment, and always its effect keeps cavity portion to be in stress-free state; Lower through-hole 4 connects an oil pipe, this oil pipe is directly communicated with fuel tank, drop in cavity portion 5 by the hydraulic oil may taken out of behind seal ring first foundation ring 1 during piston rod work, owing to there is no pressure in cavity portion 5, so when piston rod is by can not drag-out force feed during second guard ring, and the oil pipe that the hydraulic oil dropped in cavity portion 5 connects through lower through-hole 4 is directly got back in fuel tank, the situation decreasing hydraulic oil waste occurs.
Seal ring of the present utility model, through practical application repeatedly, can solve the problem of leakage of oil effectively, and compared with the mode of traditional replacing piston rod, only the processing charges of this seepage-proof oil seal ring just saves more than 7000 yuan.In addition, the improvement of sealing circle also greatly reduces cost of production, improves productivity effect, according to conservative estimation, adopt the seal ring after improving can save 5 liters * 300 days=1500 liters, hydraulic oil every year, if by the 17.8 yuan of calculating of often liter of hydraulic oil, 1500*17.8=26700 unit can be saved every year.
Protection domain of the present utility model is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the utility model discloses, the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
