One of tool is often referred to oil diffusion pump.Diffusion pump is a kind of secondary pumps, it needs mechanical pump as fore pump.
Vacuum drying oven diffusion pump exposes some problems in use at present, such as:There are problems that oil droplet splashes down, very
After empty diffusion pump is preheated, when opening main valve, a large amount of oil droplets existing for script will be with the promotion of valve deck and sputter on valve deck
Drippage, the oil droplet part splashed down can be dropped into diffusion pumping hole, be returned in diffusion pump;The oil droplet splashed down some can fall on
To outside diffusion pumping hole, vacuum chamber can be flowed into after having collected more, vacuum environment is caused to be destroyed, and pollute workpiece, damage is set
Standby, cleaning up also causes high effort for.
In conclusion vacuum drying oven diffusion pump splashes down and pollutes the two big urgent problem to be solved such as workpiece there are oil droplet at present.
Utility model content
The technical problems to be solved in the utility model is to overcome existing vacuum drying oven during the work time, and oil droplet is splashed down and polluted
The defect of workpiece provides a kind of vacuum drying oven diffusion pump oil baffle, to solve the above problems.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
A kind of vacuum drying oven diffusion pump oil baffle of the utility model, including interior oil baffle, outer oil baffle and valve deck, valve deck are set
The diffusion pump above device and below face is set, diffusion pump surface size is identical as valve deck and pumping hole is provided with sealing flange,
Sealing flange is looped around at pumping hole and contact site passes through encapsulation process, and interior oil baffle is welded on the outside of sealing flange, interior gear oil
It encloses open top and is more than valve deck, outer oil baffle is welded and fixed on the outside of interior oil baffle.
As a kind of optimal technical scheme of the utility model, interior oil baffle and outer oil baffle are made of alloy, are completed
After carry out stress relief annealing process, stability is good, and buckling performance is good, and can ensure its size, good appearance well.
As a kind of optimal technical scheme of the utility model, interior oil baffle side forms back taper angle and higher than sealing
Flange, so that the oil droplet splashed down can be pushed to be slipped to the old place at work, space is also reasonably utilized.
As a kind of optimal technical scheme of the utility model, welding fabrication after outer oil baffle and the processing of interior oil baffle, weldering
The type of being connected into has saved cost.
As a kind of optimal technical scheme of the utility model, outer oil baffle is higher than interior oil baffle, outer oil baffle and interior gear
Scraper ring complements one another, and prevents the oil droplet splashed down from polluting workpiece.
The advantageous effect that the utility model is reached is:The utility model is reached by creating newly-installed interior oil baffle
The effect for preventing greasy dirt realizes the most of oil droplet of barrier, ensures the function of the working performance of vacuum drying oven, when work, in main valve
One circle oil baffle of welding on the outside of valve bonnet seal flange, stops that most of oil droplet for splashing out flange port, the height of interior oil baffle are higher than
Sealing flange, such setting make most of oil droplet be blocked, can not splash down in outside, solve the problems, such as that oil droplet splashes down;
By creating newly-installed outer oil baffle, achievees the effect that avoid workpiece contamination, realized the function of protection workpiece, connect in main valve
The one outer oil baffle of circle of pipe end welding, it is higher than inner ring oil baffle, stop the oil droplet being splashed to outside inner ring oil baffle, outer oil baffle by
In higher than interior oil baffle, though such setting so that most of oil droplet to fall on outer gear if splashing down on the outside of interior oil baffle oily
Inner wall surface is enclosed, original place is largely flowed back to, solves the problems, such as pollution workpiece.
