Abstract
The utility model discloses a sealing arrangement of an oil-gas mixing oil cylinder, and relates to the technical field of hydraulic cylinder sealing. The sealing arrangement comprises a dustproof seal, a low-pressure seal, a step seal, a supporting seal and a pollution cleaning seal, the dustproof seal, the low-pressure seal, the step seal, the supporting seal and the pollution cleaning seal are inwards arranged on the outer end face between a piston rod and a guide sleeve in sequence, and the good chemical particle removing and purification capacity, bur scrapping-off capacity and self-lubrication capacity are achieved. The arrangement improves the reliability and safety of products, prolongs the service life of the products, and is beneficial to the improvement of the overall quality level of the products.
Description
Technical field
The utility model relates to hydraulic cylinder sealing technical field, specifically a kind of seal arrangement of air-fuel mixture oil cylinder.
Background technique
At present, domestic mining dump truck suspension hydraulic cylinder guide sleeve seal arrangement is different.Mining dump truck at work hydraulic cylinder works is frequent, impact large, and suspension hydraulic cylinder supports the weight in whole compartment especially, when vehicle travels on rough road, bear ground and pass to the impact force of vehicle body, impact to automobile while bearing ore whereabouts when adopting power shovel to load ore, the low pressure of conventional arrangement is even with no pressure is sealed in this severe working environment, very easily produce sealing back pressure, in the course of time guide sleeve sealing will be lost efficacy, cause oil hydraulic cylinder generation leakage of oil, gas leakage and guide sleeve corrosion, piston rod corrosion, causing complete machine cannot work, to construction operation, make troubles, to client, cause economic loss.
Summary of the invention
For existing practical problem in above-mentioned, the utility model provides a kind of seal arrangement of air-fuel mixture oil cylinder, is mainly used in mining dump truck suspension hydraulic cylinder, guarantees the safe and reliable operation of hanging oil cylinder.
The utility model is achieved through the following technical solutions: a kind of seal arrangement of air-fuel mixture oil cylinder, comprises the dust sealing of inwardly laying successively from exterior edge face between piston rod and guide sleeve, low pressure seal, this special envelope, supporting sealing and scrubbing sealing.
It is further: the preferred Ai Luote dust ring of described dust sealing.
The preferred prefastening RU6 sealing of described low pressure seal.
The described special envelope of preferred RSK Si of this special envelope, the special envelope of described RSK Si adopts PTFE+ carbon to fill.
Described supporting seals preferred C380 supporting ring.
Described scrubbing seals preferred T47 and receives dirty ring.
The utility model has solved the shortcomings such as low pressure poor sealing performance even with no pressure, life-span of conventional arrangement be short.Not only improve reliability, Security and the working life of product, and be beneficial to the lifting of product total quality level.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of seal arrangement of air-fuel mixture oil cylinder.
In figure: 1, scrubbing sealing; 2, supporting sealing; 3, this special envelope; 4, low pressure seal; 5, dust sealing.
Embodiment
Be below a specific embodiment of the present utility model, and be further described by reference to the accompanying drawings.
As shown in Figure 1, a kind of seal arrangement of air-fuel mixture oil cylinder comprises the dust sealing 5 of inwardly laying successively from exterior edge face between piston rod and guide sleeve, low pressure seal 4, this special envelope 3, supporting sealing 2 and scrubbing sealing 1.
Dust sealing 5 is selected Ai Luote dust ring, and Ai Luote dust ring has the superior bur ability of striking off and selflubricating ability, frequent use can not damaged the body of rod yet, and can be adsorbed small pollutant.
Low pressure seal 4 is selected prefastening RU6 sealing, and it has outstanding low pressure sealability even with no pressure, allows larger monolateral gap.
Si Te envelope 3 is selected the special envelope of RSK Si, and the special envelope of RSK Si adopts PTFE+ carbon to fill, and has good chemistry except grain purifying ability, is specifically designed to air-fuel mixture medium.
C380 supporting ring is selected in supporting sealing 2.
Scrubbing sealing 1 selects T47 to receive dirty ring.
