Abstract
The utility model relates to a sink-type installing structure for a gas-oil separator core. The sink-type installing structure comprises a gas-oil separator barrel body, an upper cover of the barrel body and the gas-oil separator core, wherein the inner edge of the gas-oil separator barrel body is provided with a step; the gas-oil separator core is provided with a flange face and is installed on the gas-oil separator barrel body step; a lower sealing pad is arranged between the gas-oil separator barrel body step and the flange face of the gas-oil separator core; the flange face of the gas-oil separator core is provided with a pressing plate, and the pressing plate is fixed through bolts; a sealing pad is arranged between the gas-oil separator barrel body and the upper cover of the barrel body; and the barrel body, the sealing pad and the upper cover are fixed through bolts. The sink-type installing structure for the gas-oil separator core disclosed by the utility model is characterized in that only two sealing surfaces are in the risk of leakage, so that the leakage points of compressed mixed gas in the gas-oil separator barrel body are reduced; meanwhile, an oil content core can be subjected to reliable electrostatic grounding, therefore, fire hazards because too much static electricity is accumulated in the oil content core can be avoided; and oil can be prevented from leaking from the sealing pad of the oil content core.
Description
Technical field
The utility model relates to the screw compressor manufacturing, be particularly related to a kind of sunk type mounting structure of built-in deaerator core (hereinafter to be referred as the oil content core) of helical-lobe compressor, mainly be to prevent the too much initiation fire of oil content core accumulation of static electricity, avoid the sealing gasket seepage of oil simultaneously from the oil content core.
Background technique
Screw compressor adopts two kinds of oil content cores usually at present: one is external oil content core, direct spinning, and this paper does not describe in detail; Two is built-in oil content core, and it is positioned over the deaerator inner barrel.Often there is following shortcoming in built-in oil content core:
Can't guarantee the reliable ground of oil content core.The oil content core can be at a large amount of static of the surface of oil content core accumulation through long-play, and these static must ground connection be derived, otherwise can cause that the gas mixture of high temperature catches fire breaking out of fire.
In order to prevent the leakage of the compressed mixed oil gas in the deaerator cylindrical shell, the most existing compressor adopts in oil content core upper and lower surface increases sealing gasket, the sealing gasket material is non-conductive, so set up staple on the surface of sealing gasket, perhaps sets up the composite of copper sheet and staple.
If set up staple separately, staple is absorbed in sealing gasket easily, can't guarantee the reliable ground of oil content core.And for example fruit winding copper sheet adds staple again, can cause the in uneven thickness of sealing gasket, and the compressed mixed oil gas in the deaerator cylindrical shell can leak along this gap.
In view of this, seek a kind of deaerator core sunk type mounting structure and become pursuing one's goal of these those skilled in the art.
Summary of the invention
Task of the present utility model provides a kind of deaerator core sunk type mounting structure, and it has solved two problems that existing fuel injection helical lobe compressor exists: first is the reliable ground of built-in oil content core, avoids because of the static initiation fire; Second is the leakage point that reduces the compressed mixed oil gas in the deaerator cylindrical shell.
Technical solution of the present utility model is as follows:
A kind of deaerator core sunk type mounting structure, comprise deaerator cylindrical shell, cylinder top cover and deaerator core, the edge is provided with step in the described deaerator cylindrical shell, described deaerator core has flanged surface, the deaerator core is installed on the deaerator cylindrical shell step, between deaerator cylindrical shell step and deaerator core flanged surface the lower seal pad is housed;
Settle pressing plate on the described deaerator core flanged surface, and fix by screw;
Between described deaerator cylindrical shell and the cylinder top cover sealing gasket is housed, by screw fixed cylinder, sealing gasket and loam cake.
Described deaerator cylindrical shell step external diameter is greater than deaerator core flanged surface external diameter.
Described pressing plate is a steel plate.
Because the conventional mounting structure of existing helical-lobe compressor exists the spillage risk of four sealing surfaces, there is risk in the electrostatic grounding of oil content core simultaneously, and adopt deaerator core sunk type mounting structure of the present utility model, only there are two sealing face leakage danger, the electrostatic grounding of oil content core is reliable simultaneously, can prevent the too much initiation fire of oil content core accumulation of static electricity, avoid the sealing gasket seepage of oil simultaneously from the oil content core.
It is reliable that deaerator core sunk type mounting structure of the present utility model has built-in oil content core ground connection, avoids because of the static initiation fire, reduces advantages such as the interior compressed mixed oil and gas leakage point of deaerator cylindrical shell.
Description of drawings
Fig. 1 is the schematic representation of a kind of deaerator core sunk type mounting structure of the present utility model.
Fig. 2 is the part-structure enlarged view among Fig. 1.
Reference character:
1 is the deaerator cylinder top cover, and 2 is sealing gasket, and 3 is the deaerator cylindrical shell, and 4 is pressing plate, and 5 for the deaerator core is the oil content core, and 6 is the lower seal pad.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of deaerator core sunk type mounting structure, comprises that deaerator cylindrical shell 3, deaerator cylinder top cover 1 and deaerator core are oil content core 5.
Along being provided with step, oil content core 5 has flanged surface in the deaerator cylindrical shell 3, and oil content core 5 is installed on deaerator cylindrical shell 3 steps, installing lower seal pad 6 between deaerator cylindrical shell 3 steps and oil content core 5 flanged surfaces.Because the cooperation flanged surface of deaerator cylindrical shell 3 is thicker, therefore the edge is provided with step in cylindrical shell 3, and this step external diameter is greater than oil content core 5 flanged surface external diameters.Press auger shell hole, oil content core 5 flange hole position on cylindrical shell 3 steps, attention must not drill flange.
On oil content core 5 flanged surfaces, settle pressing plate 4, and fix by screw.This pressing plate 4 can be steel plate.
Installing sealing gasket 2 between deaerator cylindrical shell 3 and cylinder top cover 1 is by screw fixed cylinder 3, sealing gasket 2 and loam cake 1.Cylinder top cover 1 is a flanged surface, and the surface roughness Ra of sealing face is 3.2 μ m.
The installation process of deaerator core sunk type mounting structure of the present utility model in concrete enforcement is as follows:
In sum, it is reliable that deaerator core sunk type mounting structure of the present utility model has built-in oil content core ground connection, avoids because of the static initiation fire, reduces advantages such as the interior compressed mixed oil and gas leakage point of deaerator cylindrical shell.Adopt deaerator core sunk type mounting structure of the present utility model, can prevent the too much initiation fire of oil content core accumulation of static electricity, avoid the sealing gasket seepage of oil simultaneously from the oil content core.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim variation, the modification of the foregoing description.
