Definitions

the invention relates to a vacuum pump arrangement according to the preamble of 1. Protection claim.
Vacuum pumps in which the invention can be used particularly effectively can be rotating pumps, especially friction pumps. They exist usually from a number of levels, which are designed differently can and each have rotor and corresponding stator components. This Pump-active components are penetrated by the gas to be pumped. To optimal Pump properties, such as maximum gas throughput and maximum compression, To reach the rotating parts at high speed circulate. The drive energy required for this purpose is only partially in transformed kinetic energy. Much of it is called heat loss released. Further undesirable amounts of heat are released through storage (mechanical losses due to friction in ball bearings or electrical Losses in magnetic bearings) and by compression and friction of the gases.
the amount of gases pumped by a vacuum pump is among others depends on the temperature in the scoop chamber.
the amount of gas is higher Temperature per unit volume is lower than at lower temperature. It is So it makes sense to take measures to increase the temperature in the scooping chamber to reduce.
the rotor temperature becomes due to the heat dissipation to the pump housing affected. With a cool pump housing and thus a larger one The temperature difference between the rotor and the housing is the one that arises on the rotor Heat dissipated better. This allows the amount of gas to be pumped increase.
a lower rotor temperature also has a positive effect the lifespan.
vacuum pumps are of conventional design directly connected to the recipient.
cooling devices which are integrated in the pump housing.
Such a rigid solution fixes the increased manufacturing costs even for the applications where one Cooling at the appropriate point is not necessary.
the invention is based on the object of presenting a vacuum pump which effectively dissipates the heat generated during operation can.
the construction should be simple and inexpensive to implement and variable be applicable.
the arrangement according to the invention is a simple construction. You can in Principle of every pump both in the high vacuum range and in the fore vacuum area to be attached. If necessary, several components can be put together to be assembled. By varying the temperature of the tempered liquid the temperature at different points of the pump depending on the requirement adjusted and so the thermal conditions optimal to the application and the operating status can be adjusted. In particular, there is Possibility, for example, of a higher temperature on the fore-vacuum side generate to prevent condensation at this point.
the pump is with the housing 1, which has a suction opening 2 and Has gas outlet opening 3, provided.
the rotor shaft 4 is in bearings 5 and 6 fixed and driven by the motor 7.
Component 18 attached, which has a temperature control device 20.
a first embodiment (Fig. 2) is the component on the circumference with a groove 21 for Providing a tubular hollow body 22 provided. Through this hollow body flows through an inlet connection 23 and a corresponding one, not here shown outlet the tempered liquid.
a groove 16 is attached. This is with a sleeve 27 and Sealing devices 28 closed.
the tempered in this groove Liquid via an inlet connection 31 and one not shown Flow outlet pipe.
FIG. 4 Another embodiment is as a detail in Fig. 4 and for better explanation shown again in Fig. 4a in plan view as a section.
Component 18 with bores 32 extending in the tangential direction for receiving the tempered liquid.
ком ⁇ онент 18 can be between Pump and recipient can be arranged. Via a temperature control device 35 The temperature of those flowing through the component 18 can be known per se Liquid can be adapted to the requirements.
the invention enables better heat dissipation from the pump flange as well thermal decoupling from the recipient.
the temperature control is independent of the pump cooling circuit. Existing systems can easily can be converted by adding one or more components.
the invention Arrangement not only allows cooling, but also beyond general temperature control in the area used.
