Opis:
In this paper, the authors have discussed the subject of fire and explosion hazards during the operation of a modern ship's high-power internal combustion engines. The causes of the occurrence of and the methods of preventing explosions in the starting manifolds of modern piston combustion engines equipped with a pneumatic starting system, with starting valves on the cylinder heads, have been specified. The concept of an active system for monitoring the technical condition of the starting valves has been presented in order to quickly diagnose leakages and reduce the risk of explosion. A conceptual design of a prototype of a non-invasive, new generation leak detector for starting valves and its technical design have been presented. Exemplary implementations of the prototype detector have been shown and its selected functionalities have been discussed. This paper has ended with an assessment of the possibility of further development and the applications of this device.

Opis:
The article presents the results of selected energy parameters calculations, carried out for the recorded values of instantaneous voltages and currents in the three-phase power supply of the model vibratory unit. The parameters were the values of active and apparent power taken from the drive consisting of two electric motors supplied by the inverter for selected frequency settings and directly from the power grid. In addition, calculations of tgφ power factor values were made to evaluate the compensation of reactive power consumption in the tested power systems. Measurements and calculations lead to the conclusion that if the frequency of the inverter output voltage rises, the active and apparent power consumed by the model vibratory drive unit increases. The active and apparent power for setting the output frequency of the inverter from 50 Hz was less than the active and apparent power taken by the model vibratory unit that was powered directly from the power grid. The power factor tgφ in the power supply system was approximately 6, except one case (f = 30 Hz).
