The realization of this structure of rotating cylinder transmission cooling system allows to utilize the cooling medium of the bearing oil of rotating cylinder transmission device as the rotating cylinder transmission device.This allows to abandon the optional equipment into cooling rotating cylinder transmission device, thereby can build the little and simple centrifugal separator of size.
Centrifugal separator may link to each other for simultaneously the pump of rotating cylinder actuator beairng fuel feeding with the diffusion pump of band coolant jacket with oil groove by heat exchanger, the coolant jacket of diffusion pump and this three of coolant jacket of rotating cylinder transmission device.
Such solution allows the cooling diffusion pump and need not to adopt additional cold-producing medium and supplementary equipment therefore, and this also makes centrifugal separator simplify and reduce weight.
The present invention will be further explained by the detailed description and the accompanying drawings of its specific embodiment, and these accompanying drawings are:
Fig. 1 represents centrifugal separator, by the present invention, vacuum and refrigeration system is arranged, and lubricating system and cooling system are arranged;
Fig. 2 represents that centrifugal separator has the embodiment of diffusion pump.
At the centrifugal separator of high rotating speed of having of industrial use and so-called hypervelocity, the vacuum system that keeps necessary vacuum, the refrigeration system that keeps the necessary temp situation are arranged usually, the lubricating system and the cooling system of rotational parts (particularly bearing).
Turn to Fig. 1 now, concrete, the unrestriced embodiment of centrifugal separator is described with schematic form in the figure.At vacuum chamber 1(Fig. 1) in keep the vacuum system of desired vacuum, wherein contain vavuum pump 2.In vacuum chamber 1, place and guarantee to be the equipment of centrifugation institute necessary condition.
Refrigeration system comprises refrigeration unit 3 and the evaporimeter 4 that is contained in the vacuum chamber 1.Between the sleeve 5 of 1 bottom, chamber and evaporimeter 4, heater 6 is housed.
Work rotating cylinder 7 is housed in chamber 1, and it is fixed on the flexible shaft 8 of transmission device 9.
Certain temperature regime of maintenance work rotating cylinder 7 realizes by refrigeration unit 3 and heater 6.
For the bearing 10 to the transmission device 9 that makes work rotating cylinder 7 rotation is lubricated, we study lubricating oil system, and there is the oil pump 11 that is contained in the oil groove 12 in this system.Filter 13 is contained in the oil groove 12, is implemented on this filtration device structure on the post 14 and with the pump 11 of charged motivation 15 to link to each other.In order to give bearing 10 by oil groove 12 fuel feeding, utilize valve 16, its nationality pipeline 17 links to each other with bearing 10, and both link to each other pipeline 18 transmission devices 9 and oil groove 12 and as the oil spilling bucket of bearing 10.
