A method for detecting the state of operation of a rotating machine, in particular a centrifugal pump, includes detecting using at least one first temperature sensor a change in temperature in or at least one bearing region of a rotating element of the rotating machine, identifying temperature gradients using an evaluation unit, from a temperature profile generated from the at least one temperature sensor, and identifying a switch-on and/or switch-off process of the rotational movement of the machine on the basis of a characteristic of the ascertained temperature gradient.

Method for detecting the state of operation of a rotating machine

A method for protecting a pump unit comprising a variable-speed fluid-conveying device, particularly a centrifugal pump, a drive and a control system, is provided, with protection in the event of cyber attacks. Signals relating to the speed and/or speed regulation of the fluid-conveying device are detected and then evaluated to detect a maliciously effected, anomalous operation of the pump unit characteristic of a cyber attack. At least one nominal variable and at least one actual variable derived from the analyzed signal are compared. Subsequently, a unit transmits signals to components of the pump unit in order to control the operation of the fluid-conveying device in a state in which the fluid-conveying device is protected from current and/or other cyber attacks.

Method and apparatus for protecting pump units from cyber attacks

A method and device for protecting a flow-conducting device of an installation against cavitation initiated by cyber attacks. At least one signal relating to an operating state of the installation is evaluated by an evaluation unit in order to detect a cyber attack by comparison with at least one reference value. If the evaluation unit detects a willfully brought-about irregular operating mode of the installation based on the evaluation, the unit passes on signals to components of the installation to bring about an installation operating mode which is in compliance with regulations and during which generation of cavitation is avoided, and produces a state in which the flow-conducting device is protected against the current cyber attack and/or against future cyber attacks.

Method for the protection against cavitation in cyber attacks and unit for carrying out the method

A flow-conducting component such as a pump impeller is provided. Passages between vanes of the flow-conducting component include notches in the form of transitions between the vane and a common surface, such as a cover disk. The notches include a transition surface having a geometric configuration determined in accordance with a calculated load spectrum along at least a portion of the length of the notch and in accordance with a particular geometric pattern.

Flow-conducting component

A device and a method for detecting deposits () on walls () that are covered by a medium, in which as sensor () is integrated in the wall (). A component () of the sensor () locally heats the medium in a region (), and the temperature of the medium around the component () is detected. The sensor () relays temperature measurement signals to an analysis unit (), where the degree of deposit formation is determined, e.g., by comparison with stored reference data.

Device and method for detecting deposits

A centrifugal pump including a rotor and a housing surrounding the rotor, the housing having a connection on the pressure side and another on the intake side, respectively. The housing surrounding the rotor is constructed as a composite part in which a first thin-walled layer () defines the inner configuration of the housing, and at least one second layer () provides structural stability to the housing.

Centrifugal pump

A flow-ducting system with a combined pump-drive module, the pump-drive module including a drive module, and a pump module having an impeller that can be driven by the drive module, the unit including a casing having at least one inlet side and at least one outlet side and a moveable shut-off device arranged between them, a flow path between the inlet side and the outlet side being formed in at least one position of the shut-off device, and the pump module being arranged in the flow path between the inlet side and the outlet side. In at least one further position of the shut-off device (), the unit () is capable of shutting off the flow path () in such a way that the shut-off device () and the unit casing () form an area (), which is separated from the flow path () and which is sealed off from the inlet side () and the outlet side (), and the pump-drive module () is arranged at least partially inside this area ().
