An oil seal for a gas compressor comprises a first arc-shaped lip and a second arc-shaped lip, the first arc-shaped lip extends toward a compression chamber, the second arc-shaped lip extends toward an oil chamber, and the first arc-shaped lip extends toward the oil chamber. An intermediate support ring is arranged between the curved lip and the second curved lip, and the intermediate support ring is used to support the first curved lip and the second curved lip, and the first curved lip, the second curved lip and the The outer side of the intermediate support ring is fixed by the support assembly. Good sealing, the greater the pressure, the greater the axial holding force, and the sealing performance is greatly improved. When the arc-shaped lip is subjected to high pressure gas or lubricating oil pressure, the bearing capacity is strong, and it will not turn into a 90-degree right angle or even bend backwards The lip is folded and the lip is raised, resulting in oil leakage and air leakage, ensuring the sealing effect; easy installation, the curved lip will not be reversed by force, avoiding repeated installation, reducing installation difficulty, improving installation efficiency, and eliminating potential safety hazards. High safety factor, stable and reliable quality.
Description
The technical field is as follows:
the utility model relates to an oil blanket for gas compressor.
Background art:
in the field of gas compressors, oil seals are used for sealing between an oil cavity and a compression cavity, so that lubricating oil is prevented from leaking from the oil cavity to the compression cavity, and compressed gas is prevented from leaking from the compression cavity to the oil cavity. Once the lubricating oil leaks to the compression cavity, the lubricating oil can pollute the compressed gas in the compression cavity; once the compressed gas leaks to the oil cavity, the internal structure of the motor is damaged, and the service life of the motor is influenced. At present, the oil seal and the shaft are generally sealed through an arc-shaped lip, but the existing oil seal has the following defects in use:
(1) the arc lip is poor in sealing performance, when the arc lip is subjected to the pressure of high-pressure gas or lubricating oil, the bearing capacity is poor, the arc lip is easily changed into a 90-degree right angle and is even bent backwards, so that the lip port is tilted to cause sealing failure, and oil leakage or air leakage is caused;
(2) the installation is troublesome, needs interference fit to closely install between arc lip and the axle, and when the oil blanket toward epaxial suit, the easy atress of arc lip takes place the reversal, and the staff is if direct seal failure when can not result in using observed then, and the staff is if in time observe then need rework the installation to increase the installation degree of difficulty, reduce the installation effectiveness.
In summary, in the field of gas compressors, the above-mentioned problems of oil seals have become a technical problem to be solved urgently in the industry.
The utility model has the following contents:
the utility model discloses a remedy prior art not enough, provide an oil blanket for gas compressor, the leakproofness is good, and load capacity is strong, and the installation is easy, and the steady quality is reliable, and the installation effectiveness is high, has solved the problem among the prior art.
The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be:
the utility model provides an oil blanket for gas compressor, includes first arc lip and second arc lip, first arc lip extends towards the compression chamber, second arc lip extends towards the oil pocket, be equipped with middle support ring between first arc lip and the second arc lip, middle support ring is used for supporting first arc lip and second arc lip, and first arc lip, second arc lip and the middle support ring outside are fixed through supporting component.
The middle support ring comprises a first support ring and a second support ring, the first support ring is used for supporting the first arc-shaped lip, and the second support ring is used for supporting the second arc-shaped lip.
The first support ring is provided with an arc-shaped support part extending towards the compression cavity, and the second support ring is provided with an arc-shaped support part extending towards the oil cavity.
The supporting component comprises an outer fixing sleeve and a pressing sleeve, and the outer fixing sleeve is matched with the pressing sleeve to install the first arc-shaped lip, the second arc-shaped lip and the middle supporting ring in the outer fixing sleeve.
The outer fixing sleeve and the pressing sleeve are riveted and fixed.
A first gasket is arranged between the first arc-shaped lip and the outer fixing sleeve, and a second gasket is arranged between the second arc-shaped lip and the pressing sleeve.
The first gasket and the second gasket are made of rubber, metal, plastic or PTFE elastic materials.
The first arc-shaped lip and the second arc-shaped lip are made of rubber, PTFE or PTFE added with filling materials or rubber materials.
The external fixing sleeve and the pressing sleeve are made of carbon steel or stainless steel or are encapsulated by the outside.
And an annular groove or a thread groove is formed in the inner side of the second arc-shaped lip.
The utility model adopts the above technical scheme, have following advantage:
(1) the sealing performance is good, the first arc-shaped lip extends towards the compression cavity, the second arc-shaped lip extends towards the oil cavity, the larger the pressure is, the larger the axial holding force is, and the sealing performance is greatly improved; the middle support ring is used for supporting the first arc-shaped lip and the second arc-shaped lip, when the arc-shaped lips are under the pressure of high-pressure gas or lubricating oil, the force bearing capacity is strong, the arc-shaped lips cannot become a 90-degree right angle and even bend backwards to enable the lip mouth to tilt up to cause oil leakage and air leakage, and the sealing effect is ensured;
(2) the installation is easy, is used for supporting first arc lip and second arc lip through middle support ring, and when the oil blanket was toward epaxial suit, the arc lip can not the atress take place to reverse, avoids the repeated installation, has reduced the installation degree of difficulty, has improved the installation effectiveness, has eliminated the potential safety hazard, and factor of safety is high, and the steady quality is reliable.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
