Embodiment Construction

[0037] exist figure 1 In the side channel pump according to the invention, the shaft 14 is rotatably supported in the pump housing 15 . The pump housing 15 is provided with an inlet hole 16 and a discharge hole 17 , wherein the inlet hole 16 is arranged concentrically with the shaft 14 . The end of the pump housing 15 opposite the inlet opening 16 is closed so that the end of the shaft 14 is housed within the housing 15 . The other end of the shaft 14 is accommodated in the pump housing 15 by passing one end of the shaft 14 into the access hole 16, so that the pump is sealed-free in such a way that there is no place where Here the inner and outer chambers of the pump are only separated by a shaft seal. This has the advantage that escape of the conveyed medium is reliably prevented.

[0038] Furthermore, a drive motor is accommodated in the pump housing 15 , which includes a rotor 19 connected to the shaft 14 and a stator 20 . The motor is actuated via control electronics 3...

Abstract

The invention relates to a side channel pump with a pump housing (15) in which a working chamber (23) with a side channel (24) and a motor (19, 20) are arranged, and the side The channel pump has an impeller (22) in a working chamber (23) which rotates with a shaft (14) driven by a motor (19, 20). According to the invention, a cooling circuit (40, 44, 45, 46) extends from the working chamber (23) to the motor (19, 20) and from the motor (19, 20) to the suction section (46) of the pump, wherein, The cooling circuits (40, 44, 45, 46) are supplied by the working chamber (23), the output side of which is connected to the output hole (17) of the side channel pump. With this pump gas can be sucked in without the pump overheating.

Description

technical field [0001] The invention relates to a side channel pump with a pump housing. A working chamber with a side channel and a motor are arranged in the pump housing. The impeller in the working chamber rotates with the shaft driven by the motor. Background technique [0002] Side channel pumps have been known for a long time (document DE 855 363). They are used to transport liquids and mixtures of liquids and gases. The advantage of side-channel pumps is that the operation of the pump is only insignificantly impaired if larger quantities of gas are also entrained in the liquid. [0003] It is known externally that initially a pure gas can be conveyed with a side channel pump in order to thereby suck the liquid to be conveyed into the pump. This is then also possible when the working chamber is dry, ie initially contains no liquid volume in the working chamber, document WO 2014 / 033317 A1. For this purpose, the pump is operated at a high rotational speed, so that i...
