In view of this, a kind of new vacuum pump need be provided.
The model utility content
In view of the deficiency of above-mentioned existing technology, the purpose of the utility model is to provide a kind of liquid-ring vacuum pump, is permitted often to change problems such as accessory, maintenance cost height with the vacuum pump that solves the available technology adopting hydraulic jack.
In order to achieve the above object, the utility model has been taked following technological scheme:
A kind of liquid-ring vacuum pump; Comprise being used for the pump housing that the air in the press is extracted, wherein, also comprise: Roots pump, ice water system; Said Roots pump connects press; Said ice water system connects the carbonated drink knockout drum through water pump, and said carbonated drink knockout drum links to each other with the pump housing through first pipeline, second pipeline respectively, and said ice water system links to each other with Roots pump through the 3rd pipeline, the 4th pipeline.
Described liquid-ring vacuum pump wherein, also comprises a valve, and said valve is arranged on the 3rd pipeline.
A kind of vacuum system wherein, comprises described liquid-ring vacuum pump and a plurality of press, and said liquid-ring vacuum pump links to each other with each press respectively.
Described vacuum system wherein, also comprises a PLC control gear, is used to control each press according to certain sequence starting and shutdown.
The liquid-ring vacuum pump that the utility model provides; Comprise the pump housing that is used for the air in the press is extracted and Roots pump, ice water system; Said Roots pump connects press; Said ice water system connects the carbonated drink knockout drum through water pump, and said carbonated drink knockout drum links to each other with the pump housing through first pipeline, second pipeline respectively, and said ice water system links to each other with Roots pump through the 3rd pipeline, the 4th pipeline.Described liquid-ring vacuum pump adopts water as working solution, does not have the machinery wearing and tearing, and 100% does not have oil, less demanding to air-breathing medium, also have operate steadily, advantages such as the life-span is longer, non-maintaining maintenance.
Description of drawings
The schematic representation of the liquid-ring vacuum pump that Fig. 1 provides for the preferable enforcement of the utility model.
Embodiment
The utility model provides a kind of liquid-ring vacuum pump.For the purpose, technological scheme and the effect that make the utility model is clearer, clear and definite, below with reference to accompanying drawing and give an actual example to the utility model further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, the schematic representation of the liquid-ring vacuum pump that Fig. 1 provides for the preferable enforcement of the utility model.As shown in the figure; Said liquid-ring vacuum pump comprises: the pump housing 100 that is used for the air in the press 10 are extracted and Roots pump 200, ice water system 300; Said Roots pump 200 connects press 10; Said ice water system 300 connects carbonated drink knockout drums 500 through water pump 400, and said carbonated drink knockout drum 500 links to each other with the pump housing 100 through first pipeline 610, second pipeline 620 respectively, and said ice water system 300 passes through the 3rd pipeline 630, the 4th pipeline 640 links to each other with Roots pump 200.
Specifically, its workflow is following: the pump housing 100 with said liquid-ring vacuum pump extracts press 10 air, when being extracted into certain negative pressure, adopts Roots pump 200 to continue to take out, and negative pressure value is increased; Utilizing simultaneously with ice water system 300 cools off for the cold water circulation of carbonated drink knockout drum 500 through water pump 400 raising frozen water.Be, because the pump housing 100 has negative pressure to produce when vacuumizing, so the water in the carbonated drink knockout drum 500 can get into the pump housing 100 through first pipeline 610 automatically with should be noted that; Simultaneously, because Roots pump 200 need cool off and seal when vacuumizing, so cool off for Roots pump 200 by force through 630 water inlets of the 3rd pipeline, 640 water outlets of the 4th pipeline.
Please continue to consult Fig. 1; It is following to describe vacuum from the angle of gas flow process below: the air the press 10 is evacuated to the Roots pump 200. and the pump housing 100; Hydration gas mixture in the said pump housing 100 gets into gas water separation tank 500 through pipeline second pipeline 620 and carries out air-water separation, accomplishes the process that vacuumizes.
Further; Comprise that also one is arranged on the valve on the 3rd pipeline; Pass through with flexible outlet valve can guarantee that it all is being in the best efficiency point operation in the vacuum ranges; In addition, impeller is cavitated and is reduced noise in the time of can also having avoided near limiting vacuum through an exclusive cavitation erosion protective gear.
