Abstract
The invention relates to a vacuum obtaining apparatus, namely a dry type screw rods vavuum pump that designs two screw rods into hollow and employs the heat pipe internal cooling method. In the heat pipe internal cooling dry type screw rods vacuum pump provided by the invention, the screw rods are made into hollow; the internal of the screw rods are cooling chambers, which is convenient for cooling the screw rods, taking away the heat generated by the screw rods, therefore the surface temperature of the screw rods is reduced, the problem of medium solidification carbon formation generated in the process of pumping the medium by the screw pump is solved, and service life of the screw rods are greatly improved.
Description
Technical field
The present invention relates to pumping equipment, is that two screw rods are made into the dry screw vacuum pump that cools off in hollow and the employing heat pipe.
Background technique
Screw vacuum pump has been proved to be the dry vacuum pump of function admirable, it has, and ultimate pressure is low, vacuum system is simple and direct, active chamber does not have any medium, can obtain clean vacuum, advantages such as applied widely, environmental protection, be applied to all trades and professions more and more, replace traditional water ring vaccum pump and oil-sealed vacuum pump.Screw vacuum pump in the market is easy to generate medium and solidifies carbon distribution because the work cavity temperature is higher, has seriously influenced the working life of vacuum pump, and needs the curing carbon distribution in the periodic cleaning active chamber.
Summary of the invention
The present invention provides cooling dry screw vacuum pump in a kind of heat pipe in order to solve the above-mentioned problems in the prior art.
To achieve these goals, the technical solution used in the present invention is: cooling dry screw vacuum pump in a kind of heat pipe comprises the pump housing, motor, intermeshing right handed screw and left handed screw; The described pump housing, the mesospore that is installed in pump housing outside and exhaust cap constitute closed cavity jointly; Right handed screw and left handed screw are fixed on the screw axis; The two ends of screw axis are separately fixed on mesospore and the exhaust cap; The front end of described screw axis is equipped with driving gear; Motor drives left handed screw and right handed screw rotation by coupling and driving gear; Described right handed screw and left handed screw are hollow structure, and helical tooth inside is cooling chamber.
Described screw axis is hollow structure.
In the described cooling chamber cooling medium is housed, deaeration and sealing, thus form cooling structure in the hot tube.
Bonnet at the pump housing is equipped with cooling oil pump, and described cooling oil pump cools off screw axis.
Described exhaust cap is provided with relief opening.
The cooling dry screw vacuum pump is compared with existing screw vacuum pump and is had the following advantages in the heat pipe of the present invention:
1. screw rod is made into hollow structure, screw rod inside is cooling chamber, is convenient to screw rod is cooled off, and the heat that screw rod work produces is taken away, thereby reached the purpose that reduces the screw surface temperature.Screw rod working surface temperature reduces, and can solve the problem that medium that screw pump produces in pumping the medium process solidifies carbon distribution effectively, has greatly improved the operating life of screw rod.
2. adopt the stainless steel hollow screw, alleviated rotor weight, saved the operation of screw rod working surface coating corrosion-inhibiting coating; Improve the running accuracy of screw rod, solved the problem that corrosion-inhibiting coating comes off, reduced the cost of production of screw rod.
3. the change of relief opening position, gas medium can be pumped in the process, liquid and solid particle that liquefaction and curing produce are discharged, and the material that has solved original screw pump generation can't be discharged, the problem that screw pump workpiece wearing and tearing are big has improved reliability and the operating life of screw pump.
