Description
Technical field
The utility model belongs to field of mechanical technique, relates to cooling system, particularly a kind of sliding valve vacuum pump cooling system.
Background technique
At present sliding valve vacuum pump is widely used in the vacuum impregnation, vacuum drying process of transformer, electric wire, the capacitor of power industry.Be vacuum coating, vacuum smelting, vacuum heat treatment, vacuum oil strain, lyophilisation; The comparatively ideal vacuum equipment of aviation simulation test.
Along with the continuous development of industrial technology, people constantly promote the requirement of vacuum equipment, how to produce to vacuumize the higher and equipment reliability that do not descend of efficient and become the target that vacuum equipment manufacturers are pursued.But also brought other problems when having solved the pumping speed problem; Because swing speed rises; How effectively cooling is cooled to for a difficult problem to equipment; Sliding valve vacuum pump active chamber swing efficient height then temperature is prone to raise, if under this environment, work for a long time, has had a strong impact on the working efficiency and the operating life of sliding valve vacuum pump.Traditional type of cooling has air-cooled and water-cooled, because active chamber is inner at the sliding valve vacuum pump pump housing, and then air-cooled poor effect; Water-cooled then need be designed a cooling chamber and come the active chamber of sliding valve vacuum pump is cooled off.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology; A kind of sliding valve vacuum pump cooling system has been proposed; This sliding valve vacuum pump cooling system can effectively reduce the active chamber temperature under the situation of not changing pump housing internal structure; Improve working efficiency, prolonged the working life of pump.
The purpose of the utility model can realize through following technical proposal: a kind of sliding valve vacuum pump cooling system; Sliding valve vacuum pump comprises the pump housing and the active chamber that is positioned at the pump housing; This cooling system comprises the cooling chamber that is positioned at the pump housing, and described cooling chamber is wrapped in the outside of active chamber; It is characterized in that the described pump housing is provided with ball valve, Decompression valves and feed pathway; The import of ball valve is connected with the bottom of cooling chamber, and described feed pathway is connected with the top of cooling chamber; The import of described Decompression valves is connected with cooling chamber.When sliding valve vacuum pump was worked, water intake began water inlet, and water is in liquid inlet channel injects cooling chamber, and water is full of cavity gradually; Water temperature in the cavity raises, because the pump work time is long, when the water-cooled effect descended, then water intake pressure increased, and opens the bottom ball valve and carries out draining, and the Decompression valves of bottom is opened automatically when the liquid inlet channel water feeding pressure is too high, carry out pressure release, thereby the equipment that prevents is impaired.
In above-mentioned sliding valve vacuum pump cooling system, the import of described Decompression valves is connected with the bottom of cooling chamber.Too high when intake pressure, Decompression valves is then opened the water in the venting cooling chamber automatically, thus the decompression protection device.
In above-mentioned sliding valve vacuum pump cooling system, Decompression valves was in opening state when the force value of the inlet of described Decompression valves reached 0.25MPa～0.35MPa.Water intake pressure is not if carry out pressure release then because the excessive pipeline burst that causes of pressure when surpassing 0.25MPa～0.35Mpa.
In above-mentioned sliding valve vacuum pump cooling system, be provided with honeycomb duct in the described cooling chamber, an end of described honeycomb duct is connected with the outlet of feed pathway.Water gets into from feed pathway and through honeycomb duct water is injected in the cooling chamber.
In above-mentioned sliding valve vacuum pump cooling system, the other end of described honeycomb duct is provided with the plug of this port of shutoff, and it axially has several osculums the tube wall upper edge of described honeycomb duct.Water flows out from the osculum of honeycomb duct, thereby flows in the cooling chamber.
In above-mentioned sliding valve vacuum pump cooling system, described honeycomb duct is straight tube or swan-neck.Can select the honeycomb duct of multiple shape according to actual needs.
In above-mentioned sliding valve vacuum pump cooling system, the inlet of described feed pathway is connected with joint.Be easy to dock, make things convenient for the water filling cooling with water pipe.
Compared with prior art, this sliding valve vacuum pump cooling system has the following advantages:
1, need not to change internal structure, active chamber is carried out effective water-cooled.
2, be provided with Decompression valves in the bottom, effectively protective gear avoids causing unnecessary loss.
3, the water-cooled effect is obvious, increases work efficiency, and has prolonged operating life.
Description of drawings
Fig. 1 is the structural representation of this sliding valve vacuum pump cooling system.
Among the figure, 1, ball valve; 2, Decompression valves; 3, feed pathway; 3a, joint; 4, honeycomb duct; The 4a osculum.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As shown in Figure 1, a kind of sliding valve vacuum pump cooling system, sliding valve vacuum pump comprise the pump housing and the active chamber that is positioned at the pump housing, and this cooling system comprises the cooling chamber that is positioned at the pump housing, and cooling chamber is wrapped in the outside of active chamber; The pump housing is provided with ball valve 1, Decompression valves 2 and feed pathway 3; The import of ball valve 1 is connected with the bottom of cooling chamber, and feed pathway 3 is connected with the top of cooling chamber; The import of Decompression valves 2 is connected with cooling chamber.The import of Decompression valves 2 is connected with the bottom of cooling chamber.Decompression valves 2 was in opening state when the force value of the inlet of Decompression valves 2 reached 0.25MPa～0.35MPa.Be provided with honeycomb duct 4 in the cooling chamber, an end of honeycomb duct 4 is connected with the outlet of feed pathway 3, and the other end of honeycomb duct 4 is provided with the plug of this port of shutoff, and it axially has several osculums 4a the tube wall upper edge of honeycomb duct 4; Honeycomb duct 4 is straight tube or swan-neck; The inlet of feed pathway 3 is connected with joint 3a.
When sliding valve vacuum pump is worked, the joint 3a and the water source of the water inlet of feed pathway 3 joined, begin water inlet, water gets into liquid inlet channel 3 from the water inlet, flow into honeycomb duct 4 again, flows out the osculum 4a of water from honeycomb duct 4 to inject in the cooling chamber; When water temperature raises, the water-cooled effect descends, and then increases water feeding pressure, opens the ball valve 1 of bottom greatly, changes water, with high-temperature water discharge low temperature water mend into, required water-cooled requires high more, then water intake pressure is big more; But because honeycomb duct 4 and feed pathway 3 pipeline when pressure surpasses 0.25MPa～0.35MPa is prone to explosion, when then water intake pressure reached 0.25MPa～0.35MPa, the Decompression valves 2 of bottom was opened and carried out the draining pressure release, thereby protective gear.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
