Abstract
The invention provides a respirator for an oil cylinder. The invention provides the respirator used for a hydraulic cylinder with the advantages that the structure is ingenious, and dirty oil, sewage or dust and the like in outside environment can be effectively prevented from entering the oil cylinder. The respirator comprises a cavity, wherein the middle part of the cavity is communicated with the oil cylinder through a connecting hole, the top end of the cavity is provided with an air outlet hole, in addition, the bottom end of the cavity is provided with an air inlet hole, a one-way air outlet mechanism positioned at the upper part and a one-way air inlet mechanism positioned at the lower part are formed in the cavity, the connecting hole is positioned between the one-way air inlet mechanism and the one-way air outlet mechanism, a plurality of filtering layers are arranged between the one-way air inlet mechanism and the air inlet hole, an isolation net is arranged between the adjacent filtering layers, the filtering layers are made of active carbon, and the isolation nets are made of oil suction cotton. The respirator has the advantages that in the use process, the dirty oil, the sewage, or the dust and the like in outside environment can be effectively prevented from entering the oil cylinder.
Description
Technical field
The present invention relates to the practical application area of oil cylinder in hydraulic system, particularly relate to the improvement of the resuscitation apparatus being applicable to oil cylinder.
Background technique
In in hydraulic system, oil cylinder is as the container of hydraulic oil transfer, storage, and in the turnover repeatedly of hydraulic oil, the pressure in oil cylinder often changes floating comparatively large, usually high to the material requirements of oil cylinder, thus brings high cost.Like this, for reducing costs consideration, usually connect a resuscitation apparatus on the top of oil cylinder, thus can effectively avoid oil cylinder internal pressure excessive or too small.But the applied environment of hydraulic system is usually comparatively severe, and sump oil, sewage and dust are usually more, and like this, common resuscitation apparatus often can suck these dusts in use, and then causes damage to a whole set of hydraulic system.
Summary of the invention
The present invention is directed to above problem, provide a kind of delicate structure, can oil cylinder internal pressure excessive or too small while, effectively prevent the sump oil in external environment condition, sewage or dust etc. from entering the resuscitation apparatus for oil hydraulic cylinder in oil cylinder.
Technological scheme of the present invention is: comprise cavity, and the middle part of described cavity is communicated with described oil cylinder by attachment hole, and described cavity top end offers air outlet hole and the bottom of cavity offers inlet hole;
Be provided with superposed unidirectional air-out mechanism and the one-way air inlet mechanism being positioned at bottom in described cavity, described attachment hole is between described one-way air inlet mechanism and described unidirectional air-out mechanism;
Be provided with some filter layers between described one-way air inlet mechanism and described inlet hole, be provided with isolation net between adjacent described filter layer, described filter layer is made up of active carbon, and described isolation net is made up of oil absorbent material.
The density of some described filter layers increases progressively from top to bottom successively.
The thickness of some described isolation nets increases progressively from top to bottom successively.
When the present invention uses, when one-way air inlet mechanism opening, resuscitation apparatus is in oil cylinder during air inlet, some filter layers be made up of active carbon by setting up effectively adsorb the dust in manufacturing shop and a large amount of suspending particulate matter in air, thus effectively ensure that the purity of hydraulic oil in oil cylinder, and then effectively avoid the damage of hydraulic system.Meanwhile, be provided with between adjacent filter layers and make isolation net by oil absorbent material, on the one hand, the filter layer of different densities can be separated; On the other hand, can be separated the sump oil sucked or sewage by mistake.To sum up, can effectively prevent the sump oil in external environment condition, sewage or dust etc. from entering in oil cylinder.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 is cavity, and 11 is attachment holes, and 12 is air outlet holes, and 13 is inlet holes, and 2 is unidirectional air-out mechanisms, and 3 is one-way air inlet mechanisms, and 4 is filter layers, and 5 is isolation nets.
Embodiment
The present invention as shown in Figure 1, comprises cavity 1, and the middle part of described cavity 1 is communicated with described oil cylinder by attachment hole 11, and described cavity 1 top offers air outlet hole 12 and the bottom of cavity 1 offers inlet hole 12;
Be provided with superposed unidirectional air-out mechanism 2 and the one-way air inlet mechanism 3 being positioned at bottom in described cavity 1, described attachment hole 11 is between described one-way air inlet mechanism 3 and described unidirectional air-out mechanism 2;
Be provided with some filter layers 4 between described one-way air inlet mechanism 3 and described inlet hole 13, be provided with isolation net 5 between adjacent described filter layer 4, described filter layer 4 is made up of active carbon, and described isolation net 5 is made up of oil absorbent material.Like this, when one-way air inlet mechanism opening, resuscitation apparatus is in oil cylinder during air inlet, some filter layers be made up of active carbon by setting up effectively adsorb the dust in manufacturing shop and a large amount of suspending particulate matter in air, thus effectively ensure that the purity of hydraulic oil in oil cylinder, and then effectively avoid the damage of hydraulic system.Meanwhile, be provided with between adjacent filter layers and make isolation net by oil absorbent material, on the one hand, the filter layer of different densities can be separated; On the other hand, can be separated the sump oil sucked or sewage by mistake.To sum up, can effectively prevent the sump oil in external environment condition, sewage or dust etc. from entering in oil cylinder.
The density of some described filter layers 4 increases progressively from top to bottom successively.Thus the intensity of increase progressively " anti-dust, suspending particulate matter infiltrate ".
The thickness of some described isolation nets 5 increases progressively from top to bottom successively.Thus the intensity of increase progressively " oil resistant, water infiltrate ".
