Opis:
This paper aims to analyse the results of the comparative study of the characteristic frequencies, in terms of Power Spectral Density (PSD), generated by an SKF6322 bearing in a rotational blower. Among all the analysed frequencies, we have focused on the ones generated by the shaft rotation speed, the one on the blades and the ones of the SKF6322 bearing, such as the tracks, the cage and the balls. For this study, we followed the ISO 10816 criteria, both in the sampling part and in the data analysis, using the speed values in terms of PSD, which improves the results in both high and low frequencies. This study can be used to predict the performance of bearings and their future failure, determining the most decisive frequency, the one with the highest incidence and the relative influence of each one on the different positions and monitoring coordinate axes. This procedure can be applied to improve the predictive maintenance protocol in order to improve the performance, efficiency and reliability of the equipment with bearings in their systems.

Opis:
Changes in operating properties of the internal combustion engine, for various reasons, may manifest themselves with similar symptoms. An example is the drop in engine power, which may be caused by malfunctioning of the system such as power supply, or excessive wear geometric kinematic pairs as the piston-crankshaft. Identification of the causes of malfunction is the basis for carrying out corrective action. In practice, the workshop frequent disability are different manifestations of the drive units having identical symptoms. An alternative to iterative repair methods is the introduction of diagnostic tools that will help identify causes of failure, without having to remove the individual motor units. These provisions comply with the method of vibration analysis. The vibration signals provide information about the technical condition of the object. The paper presents examples of applying the methods of vibration in the identification of changes in the technical condition of the engine, which confirm their usefulness in identifying sources of failure. During the process of investigations, time courses of vibration accelerations were recorded with piezoelectric transducer mounted at half height of the first cylinder, perpendicular to its axis. The worked out method is based on vibration signals recorded at engine operation. The dominant amplitude components of time courses are strongly connected with air- fuel mixture ignition as well as with kinetic pairs of the engine.

In the paper selected problems related to diagnostics of onboard generators and alternators fitted with control systems are discussed. Problems refer to commutator generators and synchronous single- and threephase alternators. Special attention is paid to commutation effects. Results of incorrectness and possibility to detect them are discussed. There are also discussed effects associated with changes in a character of pulsation, which occur during shortings or insulation clearances in rotor or stator wiring. Possibility of diagnosis of generator’s or alternator’s parts by means of analysis of pulsation component parameters is indicated. In the case of alternators a number of diagnostic methods based on observation of changes in shape of voltage or frequency modulation, is discussed. This allows to detect many mechanical or electrical faults of generators, alternators or their control systems.

Badanie ultrabiomikroskopowe to silne narzędzie diagnostyczne, które może pomóc w prowadzeniu i leczeniu wielu pacjentów. Jest szczególnie pomocne w przypadku jaskry, gdyż nie zawsze patomechanizm powstawania zmian jest znany, a uszkodzenie nerwu wzrokowego często postępuje. Będąc świadomym przyczyny, można skutecznie leczyć pacjenta. Samo badanie UBM nie może jednak zastąpić pełnego badania klinicznego, włącznie z wykonaniem gonioskopii dynamicznej. Jest ono świetnym uzupełnieniem, które może potwierdzić wiele postawionych diagnoz.
Ultrabiomicroscopic (UBM) examination is a powerful diagnostic tool that can assist in the management and treatment of many patients. It is especially helpful in the case of glaucoma and damage to the optic nerve. We can successfully treat patients only if we are aware of the disease cause. Although UBM examination cannot replace a complete clinical examination (including dynamic gonioscopy), it is a great supplement that can confirm many diagnoses.
