Compressor crankcase can accomplish the air-tightness that can effectively improve crankcase.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
A kind of modified high-air-tightness compressor crankcase of the utility model, including cabinet, the bottom of the cabinet are fixed
Pedestal is installed, the center of top of the pedestal is fixedly installed with fixed disk, and the fixed disk has wrapped around box shell, described
Through several equally distributed connecting holes are provided with, the inner end of the connecting hole, which is surround, is covered with airtight circle, described on the surface of box shell
The top of box shell is covered with sealing ring, and the top surface of the box shell is provided with several equally distributed limit holes.
As a kind of optimal technical scheme of the utility model, the airtight circle is mainly made by polytetrafluoroethylene material
It forms.
As a kind of optimal technical scheme of the utility model, the sealing ring is mainly made by rubber material.
As a kind of optimal technical scheme of the utility model, the fixed disk is fixedly connected with box shell by pedestal.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model encloses the airtight circle being made by polytetrafluoroethylene material by covering one in the inner end of connecting hole,
So as to using it is airtight circle enhancing connecting hole rate of pressurization, while the utility model by the top of box shell covering one circle by
The sealing ring that rubber material is made, so as to enhance the leakproofness of crankcase connecting portion using sealing ring, so as to improve
The air-tightness of crankcase.
Detailed description of the invention

Embodiment 1
As shown in Figure 1, the utility model provides a kind of modified high-air-tightness compressor crankcase, including cabinet 1, cabinet
1 bottom is fixedly installed with pedestal 2, and the center of top of pedestal 2 is fixedly installed with fixed disk 3, and fixed disk 3 has wrapped around case
Shell 4, through several equally distributed connecting holes 5 are provided with, the inner end of connecting hole 5, which is surround, is covered with airtight circle 6 on the surface of box shell 4,
The top of box shell 4 is covered with sealing ring 7, and the top surface of box shell 4 is provided with several equally distributed limit holes 8.
Further, airtight circle 6 is mainly made by polytetrafluoroethylene material, and polytetrafluoroethylene (PTFE) does not glue commonly referred to as
Coating or material easy to clean, this material have the characteristics that antiacid alkali resistant, resist various organic solvents, are practically insoluble in all molten
Agent, meanwhile, polytetrafluoroethylene (PTFE) has the characteristics that resistant to high temperature, its coefficient of friction is extremely low, so after lubricating action being made, also at
For the ideal coating of water pipe internal layer easy to clean, often it is made into elastic sealing bands when polytetrafluoroethylene material is as sealing material
Or seal washer etc., therefore the utility model connecting hole 5 can be enhanced using the airtight circle 6 that polytetrafluoroethylene material is made
Air-tightness.
Sealing ring 7 is mainly made by rubber material, and rubber refers to the strong flexible polymer material with reversible deformation
Material, at room temperature high resilience can generate larger deformation under the external force of very little, remove resilient after external force, rubber
It is often used as sealing base part when glue material is due to its leakproofness, therefore is covered using the sealing ring 7 that rubber material is made
On the top of box shell 4, the air-tightness of crankcase can be enhanced.
Fixed disk 3 is fixedly connected with box shell 4 by pedestal 2, and user can be by crankshaft installed in one end of fixed disk 3.
Specifically, user is when using this crankcase, can first by crankshaft installed in the inside of cabinet 1, and by crankshaft with
Fixed disk 3 in cabinet 1 connects, other connecting components are connected through connecting hole 5 with crankcase by user again, in connection
In the process, airtight circle 6 is tightly sleeved in the outer end of connecting component, and airtight circle 6 is mainly made by polytetrafluoroethylene material,
The sealing performance of polytetrafluoroethylene (PTFE) is very prominent, by when be often used as sealing class material, be made by polytetrafluoroethylene material
Airtight circle 6 itself air-tightness it is very good, enhance the air-tightness at the position that crankcase and connector are connected with this, make
