“…Additional radiators 3 were mounted on the back of both hydraulic circuits, which can be switched on if the medium temperature is too high. Shut-off valves 4 were installed in each of the central pipes on the suction side and the pressure side. They allow a complete separation of the single pipes, but also the change of the hydraulic resistance and thus the load of the pump in a pipe strand.…”

“…In order to meet the efficiency requirements of the European Union, they are constructed as PMSM driven wet-rotor pumps [2,3]. Control, frequency converter, motor and impeller are combined in one integrated product [4] (see Figure 1). Microcontrollers are used to control these pumps.…”

“…Microcontrollers are used to control these pumps. In addition to current tasks, such as controlling the pump [5] and motor [4] or determining parameters such as flow or head [6], the electronics provide a platform for implementing fault detection algorithms. A few hard faults, such as overvoltage, overheating and rotor blockage can already be detected by new types of circulation pumps [7,8].…”

“…In order to save additional costs for sensors, the analysis should be limited to the data that is available anyway. For circulation pumps only the motor current is available [4]. The most widespread approach for motor fault detection on the basis of motor current evaluation is the motor current signature analysis (MCSA).…”

Pumps have a wide range of applications. Methods for fault detection of motors are increasingly being used for pumps. In the context of this paper, a test bench is built to investigate circulation pumps for faults. As a use case, the fault of impeller clogging was first measured and then examined with the help of motor current signature analysis. It can be seen that there are four frequencies at which there is an increase in amplitude in case of a fault. The sidebands around the supply frequency are in particular focus. The clogging of three and four of a total of seven channels leads to the highest amplitudes at the fault frequencies. The efficiency is reduced by 9 to 15% in case of faulty operation. These results indicate that the implementation of fault detection algorithms on the pump electronics represents added value for the pump operator. Furthermore, the results can be transferred to other applications.
