Abstract
The invention provides a method for oil purifying and vacuumizing of an electron beam (EB) furnace by utilizing a vacuum system. The method comprises the following steps: 1, dehydrating; and 2, impurity removing. The method has the beneficial effects of being applied circularly, lowering the production cost and improving the product market competitiveness.
Description
Technical field
The invention belongs to EB stove (electron beam melting furnace) vacuum pollution lard purifying method technical field.
Technical background
EB stove (electron beam melting furnace) system produces many splashes; Many cooling apparatuss that distribute leak main vacuum system mechanical pump, lobe pump, oily topping-up pump, diffusion pump, the holding pump of diffusion pump, propeller pump because a variety of causes produces; The diffusion pump propeller pump of EB rifle vacuum system (being used for slightly vacuumizing and holding pump); So just there are impurity and water molecules in these equipment hydrodynamic lubrication the insides in the vacuum system, thereby make vacuum oil oil variation affect the effect of EB stove evacuation, because vacuum oil is expensive, consumption is large, larger on the production cost impact, expensive meeting makes the product market competition ability, so just need to carry out purification processes to vacuum oil oil.At present not yet there is pair vacuum oil oil to carry out the method for purification processes.
Summary of the invention
There is the situation of impurity and water molecules in order to overcome existing EB furnace system vacuum oil, can be recycled application, reduce production costs, improve the product market competition ability, the invention provides the method that a kind of EB stove utilizes vacuum system purification vacuum oil.
The objective of the invention is to realize by following technical solution.
A kind of EB stove utilizes vacuum system to purify and vacuumizes oily method, and step of the present invention is as follows:
1) dewater:
(1) vacuumizes with the vacuum pump startup and to the working chamber;
(2) after startup vacuumizes 10 minutes, open the gas ballast valve of all mechanical pumps;
(3) in the situation that gas ballast valve is opened, the working chamber is vacuumized, can effectively make the water molecules condensation of extracting out in the working chamber, and be deposited to the mechanical pump bottom;
(4) these water moleculess can will be insoluble to the gaseous impurities absorption of vacuum oil in the mechanical pump;
(5) every 15-20 minute, open the mechanical pump fuel outlet, the water molecules that is deposited to the bottom is discharged from fuel outlet; Play the effect of purifying vacuum oil;
(6) this step repeatedly is until vacuum reaches high vacuum (＜9.0E10
-3Hpa) get final product;
2) removal of impurity:
(1) vacuumizes with the vacuum pump startup and to the working chamber;
(2) (＜1.0E10 when reaching the lobe pump entry condition
1Hpa), the online oil filtration device is connected to mechanical pump fuel outlet and oil strain mouth, starts online purolator;
(3) under this vacuum condition, vacuum pump can be extracted into the metallic impurity that swim in a large number the space, working chamber in the mechanical pump cavity, because the impurity volume is little, quality is light, so can be deposited in the vacuum oil, circulates with vacuum oil;
(4) in working cycle, with internal impact, bonding, impurity can form larger grumeleuse with insolubles in the vacuum oil, filters and the impurity of the overwhelming majority can be removed totally through online oil filtration device (5), plays the effect of purification vacuum oil;
(3) every 30-60 minute mechanical pump is once filtered, each filtration time is no less than 15 minutes and gets final product.
Beneficial effect of the present invention is that application capable of circulation has reduced production cost, has improved the product market competition ability.
Below just concrete the drawings and specific embodiments the present invention is further explained.

Fig. 2 is the deimpurity structural representation of the inventive method.
Embodiment
See Fig. 1, shown in Figure 2, a kind of EB stove utilizes vacuum system to purify and vacuumizes oily method, and step of the present invention is as follows:
1) dewater:
Vacuumize with the vacuum pump startup and to the working chamber;
After startup vacuumizes 10 minutes, open the gas ballast valve of all mechanical pumps;
In the situation that gas ballast valve is opened, the working chamber is vacuumized, can effectively make the water molecules condensation of extracting out in the working chamber, and be deposited to the mechanical pump bottom;
These water moleculess can will be insoluble to the gaseous impurities absorption of vacuum oil in the mechanical pump;
Every 15-20 minute, open the mechanical pump fuel outlet, the water molecules that is deposited to the bottom is discharged from fuel outlet; Play the effect of purifying vacuum oil;
This step repeatedly is until vacuum reaches high vacuum (＜9.0E10
-3Hpa) get final product;
2) removal of impurity:
Vacuumize with the vacuum pump startup and to the working chamber;
(＜1.0E10 when reaching the lobe pump entry condition
1Hpa), the online oil filtration device is connected to mechanical pump fuel outlet and oil strain mouth, starts online purolator;
Under this vacuum condition, vacuum pump can be extracted into the metallic impurity that swim in a large number the space, working chamber in the mechanical pump cavity, because the impurity volume is little, quality is light, so can be deposited in the vacuum oil, circulates with vacuum oil;
In working cycle, with internal impact, bonding, impurity can form larger grumeleuse with insolubles in the vacuum oil, filters and the impurity of the overwhelming majority can be removed totally through the online oil filtration device, plays the effect of purification vacuum oil;
Every 30-60 minute mechanical pump is once filtered, each filtration time is no less than 15 minutes and gets final product.
