Abstract
A kind of high pressure oil-free scroll pneumatics moving plate portion molded line head construction, it is characterized in that increasing a step body (2) close to Moving plate or quiet disk part of trying to get to the heart of a matter in Moving plate or quiet dish-type the end of a thread portion (1), thicken the molded line head of Moving plate or quiet disk, to increase the compressive resistance of molded line.The present invention is enhanced by molded line to be designed, the intensity for both guaranteeing the volumetric efficiency being vortexed while improving molded line head, to guarantee molded line life requirement under high pressure.
Description
Technical field
The present invention relates to a kind of high-speed rail technology, especially a kind of oil-free air compressor technology that high-speed rail equipment uses, tool
Say to body it is a kind of high pressure oil-free scroll pneumatics moving plate portion molded line head construction.
Background technique
The compressed air that high-speed rail equipment uses is necessary for oil-free compressed air, although current vane type, piston type are oil-free
Compressor is able to satisfy it and is infused using village, but either vane type or piston type oilless (oil free) compressor exist volume is big, manufacture at
This height, the big problem of installation and maintenance difficulty affect its popularization and application in high-speed rail equipment.And scroll compressor then has
It is small in size, manufacture problem easy for installation, but traditional automobile-used scroll compressor due to resistance to pressure it is not high, pressure at expulsion can not
Reach the 1.2MPa or more of high-speed rail equipment requirement, it is necessary to be improved.
Summary of the invention
The purpose of the present invention is there is a problem of that pressure at expulsion is too low for existing oil-free turbo-compressor, one kind is designed
High pressure oil-free scroll pneumatics moving plate portion molded line head construction, the problem of to meet high-speed rail equipment high pressure at expulsion.
The technical scheme is that
A kind of high pressure oil-free scroll pneumatics moving plate portion molded line head construction, it is characterized in that in Moving plate or quiet dish-type the end of a thread portion 1
Increase by a step body 2 close to Moving plate or quiet disk part of trying to get to the heart of a matter, thickens the molded line head of Moving plate or quiet disk, to increase molded line
Compressive resistance.
It is excessive using circular arc between the step body 2.
The step body 2, which tries to get to the heart of a matter to be connected with Moving plate or quiet disk, partially also uses circular arc excessive.
The radius of corner of the circular arc transition is R1.5 millimeters.
Beneficial effects of the present invention:
The present invention is enhanced by molded line to be designed, the intensity for both guaranteeing the volumetric efficiency being vortexed while improving molded line head, to protect
Demonstrate,prove molded line life requirement under high pressure.
The configuration of the present invention is simple, it is easy to accomplish, pressure at expulsion can be made to stablize in 1.2MPa or more.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is step body structural schematic diagram of the present invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figs. 1-2.
A kind of high pressure oil-free scroll pneumatics moving plate portion molded line head construction, in Moving plate or quiet dish-type the end of a thread portion 1(as schemed
1) increase by a step body 2(such as Fig. 2 close to Moving plate or quiet disk part of trying to get to the heart of a matter), the position of step body is 1/2 or so of molded line height
Place, the height (thickening size between 0.5-2 millimeters, be 1.5 millimeters in Fig. 2) of step, makes the molded line head of Moving plate or quiet disk
Portion thickens, can be thick with equal thickness half, and also variable thickness thickens, but far from tail portion of the type through one end should gradually transition, Cong Hou subtracts
The distance between it is as thin as normal thickness, the length of thickening (count from molded line head to normal thickness value) it is 13-15 millimeters
Between, to increase the compressive resistance of molded line.It is excessive using circular arc between two step bodies 2 up and down, it is described such as Fig. 2
Step body 2 try to get to the heart of a matter with Moving plate or quiet disk be connected part also using circular arc it is excessive.The fillet of the circular arc transition half
Diameter is R1.5 millimeters.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
