Problems solved by technology

Although there is always a residual leakage gap between the blade units, this leakage gap is small enough that it does not counteract the ingress of gas

Embodiment Construction

[0026] exist figure 1 In the case of the side channel pump according to the present invention, the shaft 14 is rotatably mounted in the pump casing 15 . The pump housing 15 has an inlet hole 16 and an outlet hole 17 , wherein the inlet hole 16 is arranged concentrically with the rotating shaft 14 . The end of the pump housing 15 opposite the inlet opening 16 is designed as a split cage 18 in which a magnet element 19 connected to the rotating shaft 14 is arranged. A magnet element 19 is arranged outside the split cage 18 , said element being connected to the output shaft of the electric motor 21 . The electric motor 21 has a controller 35 .

[0027] If the electric motor 21 is operated, the magnet element 20 performs a rotational movement around the splitting cage 18 . Rotation is also imparted to the rotary shaft 14 through magnetic force transmission, so it rotates synchronously with the output shaft of the motor 21 . Since one end of the shaft 14 enters the inlet hole 1...

Abstract

The invention relates to a side channel pump (28) and a method for operating the side channel pump (28), in which an impeller (22) rotates in a working chamber (23) having a side channel (24). According to the invention, firstly the side channel pump ( 28 ) is operated at an overspeed with a gas-filled working chamber ( 23 ). Then, the speed is reduced to operating speed to pump the liquid. The pump of the present invention has a high suction power due to the overspeed speed when the premise is to suck in gas first.

Description

technical field [0001] The invention relates to a side channel pump and a method for operating a side channel pump. In this pump, an impeller rotates in a working chamber with side channels. Background technique [0002] Side channel pumps are used for pumping liquids and gas-liquid mixtures. The advantage of side channel pumps is that even with relatively large amounts of gas entrained in the liquid, the operation of the pump is only slightly impaired. [0003] Side channel pumps can also be used to pump pure gases. For example, for pumping liquid from a tank even if the riser line is full of gas. However, in the case of side channel pumps according to the prior art, this is only possible if the working chamber contains a large amount of liquid. When the impeller rotates, the mass of liquid forms a liquid ring in the working chamber by means of which adjacent blade units are partially closed with respect to each other. Although there is always a residual leakage gap be...
