ABSTRACT:
Device for the surface cleaning of rotating machine elements such as the rotors of regenerative heat exchangers. A swinging cleaning arm is driven by an adjustable operating member to move across a rotor face through various angles, the extreme radially outer position of the cleaning arm being substantially constant, while its extreme inside positions, in various portions of its operating cycle, are variable. The operating member may be a fluid pressure motor; a control gear for the operating member contains a number of distribution sections arranged parallel in a distributing member. The distributing member is connected through connecting piping to a source of pressure fluid, and through further interconnecting piping is connected to the respective pressure spaces of respective operating members for swinging cleaning arms. The distributing member is controlled by an electric controlling member having a number of controlling sections, each controlling section having time switching elements, step-by-step selectors, and auxiliary electric controllers which may be adjusted to vary the parameters of the cleaning cycle of the cleaning arm, as required by the operating conditions of the apparatus being cleaned.
