Abstract: método para filtrar ruído de bomba. a presente invenção refere-se a um método de filtragem de ruído de pressão gerado por um ou mais bombas de pistão (1), em que cada bomba (1) é conectada a um sistema de tubulação a jusante comum (18,20), e em que a pressão de descarga é medida por um medidor sensível a pressão (26), caracterizado pelo fato de que a(s) posição(ões) angular(es) instantâneas do eixo de manivela ou do came de atuação da(s) bomba(s) (1) é/são medidas simultaneamente com a pressão de descarga e usadas como variáveis fundamentais em um modelo matemático adaptável do ruído.

Abstract: A method for detection of a fluid leak related to at least one piston machine (1), where the method includes: -- attaching a pressure sensor (18, 24) to at least a pressure side of the at least one piston machine (1); - measuring the pressure on the pressure side of the at least one piston machine (1); - attaching a transmitter (28) to the at least one piston ma-chine (1), said transmitter (28) rendering a signal for cal-culating the rotational speed of the at least one piston ma-chine (1); - calculating the speed of the at least one piston machine (1); - calculating the sum of nominal flow rates from all piston machines(1); - calculating a flow rate compensation factor; - calculating a normalized pressure (42) to be equal to the discharge pressure multiplied by the said compensation factor for the flow rate; and - monitoring the normalized pressure (42) to detect a leak-age.

Abstract: A method of filtering out pressure noise generated by one or more piston pumps (1), where each pump (1) is connected to a common downstream piping system (18, 20), and where the discharge pressure is measured by a pressure sensitive gauge (26), characterized in that the instantaneous angular position(s) of the pump(s)' (1) crankshaft or actuating cam is/are measured simultaneously with the discharge pressure and used as fundamental variables in an adaptive mathematical noise model.

Abstract: A method of determining a leakage in a piston machine comprising at least two pistons is provided. The rotational velocity of the piston machine, and therefore the volume flow through the piston machine, is varied periodically as part of a time-limited active test while measuring the differential pressure and the angular position. An angular position-based Fourier analysis of the measured values from differential pressure and rotational velocity measurements performed during the test are used to experimentally determine the amplitude ratio and phase angle difference between volume flow variations and pressure variations. The amplitude ratio and phase angle difference are used, together with an angular position-based Fourier analysis of the measurements of differential pressure and rotational speed made after the active test, to determine the amplitude and phase of the leakage flow.
