The goal of the work is by means of computer simulation to determine the dependence of the pulsation
coefficient of the output voltage of the three-phase controlled rectifier in the mode of intermittent currents on the angle of control and load parameters and to develop an analytical method for its calculation.
When installing pulsation
dampeners and back pressure valves in any pumping system, location and proximity are key.
Dhananchezhiyan and Hiremath  reported that the flow ripple is associated with pressure pulsation
in various drive frequencies of micro pumps.
Considering all of the above factors, the analysis of the impact of blood pulsation
phases on the results obtained from the Corvis tonometer is practically interesting.
Fourier analysis is employed in vibration analysis of the pressure pulsation
in fluid domain and dynamic stress in solid domain.
Monitoring points were mounted to achieve pressure pulsation
characteristics in different direction of the interface.

400 % of the pressure pulsation
in the normal mode (this is 20 ...
The pump features a closed lubricating cup and balanced stroke fluid section for steady output without any pulsation
. Designed for a wide range of material viscosities, it has a 16mm suction rod, recommended for frequent color changers, and a 25mm one for high-viscocity products up to 5,000 cps.
In parallel connection mode, the alternating operation of the pump heads results in smooth and level flow, reducing the need for additional dampening components for systems sensitive to pulsation
. Operating in the individual mode, two different liquids can be transferred simultaneously by one unit, eliminating the need for a second pump.
Due to this recent researches are concentrated on the improvement of the produced voltage quality and modulation techniques of the inverter in order to limit the torque pulsation
and speed ripple.
