Opis:
The purpose of this work is to study the effect of oil pocket shape and density on friction in reciprocating sliding. The experiments were conducted in reciprocating motion under starved lubrication conditions. Tribological tests were performed using an Optimol SRV5 tribotester. The frictional pair consisted of two discs of 42CrMo4 steel. One disc was laser textured. The oil pockets had circular and sandglass shapes. Disc samples of various texture shapes were characterized by the same pit-area ratios. The operating parameters were the same for all friction pairs. In most cases, surface texturing led to reductions in friction force value and scatter. For both dimple shapes, the best tribological properties were achieved for oil pocket density of 9%. When discs with circular dimples were tested, the highest resistance to motion was received for the highest pit-area ratio of 9%. On the contrary, the worst tribological performance of discs with sandglass-shaped oil pockets of sandglass shape were obtained for the largest oil pocket density of 22%.

Opis:
During research works concerning piston internal-combustion engines specifications of these objects are often needed. This data is usually dispersed and reaching to some is hampered or impossible. Therefore, an electronic database was drawn up about the most important ship producer’s piston internal-combustion engines for needs of exploitation investigations in the destination of gathering the necessary information. This paper presents a database of global marine diesel engines. For example, engines of the following companies were described: Akasaka Diesel, CAT, Cummins, Fiat, Hyundai, MTU, Niigata Power Systems, Pielstick, Scania, Volvo Penta etc. Information was obtained from various sources, so as websites of producers, advertising catalogues, or books and magazines about subject matter associated with marine diesel engines. This information was collected and written with the help of the program Microsoft Office. Gathered data was divided in engines of the main drive and emergency, containing details about producers, types and parameters of 2-stroke engines and four-stroke. The base enables supplementing and the alteration of entered data. Produced engines are usually operated by several dozen years after producing on swimming objects. Produced internal combustion engines are usually operated by several dozen years after producing on floating objects, and producers are merging or are stopping existing.

Opis:
The paper presents results of the research related to the analysis of the thermodynamic and flow processes occurring in a prototype VC 20.96 two-stage liquid-cooled reciprocating compressor. The compressor has been developed and manufactured by H. Cegielski Poznan metal works in collaboration with the Poznan University of Technology. The research related to the VC compressor was realized within the KBN 3127/C.T07-6/2002 project titled “Development of design of type-series of reciprocating compressors and their implementation in production”. The basic task of the project was to develop two type-series of liquid- and air- cooled reciprocating compressors of the V- and W- arrangement, designed to serve as marine engine starters. The result of the design work was the manufacturing of two compressors: the VC 20.96 liquid-cooled compressor and the WP 18.80 air-cooled one. The main aim of the research described in this paper was to evaluate the efficiency of the cooling system which uses inter-coolers integrated with the compressing stages and the cooperation of the compressing stages in terms of pressure ratio distribution. Owing to the cooling method, the applied design assumptions enabled to develop a compact compressor fulfilling the assumed operating parameters.

Żadne z obowiązujących obecnie norm dotyczących zagadnień diagnostyki drganiowej nie poruszają tej problematyki, w związku z czym diagności nie mają poziomu odniesienia dla zmierzonych parametrów drganiowych. W pracy skupiono się na diagnostyce dwóch typów sprężarek przeznaczonych dla celów nurkowych i technik hiperbarycznych. Zaproponowano tok postępowania w czasie pomiarów. Wskazano dalsze kierunki służące opracowaniu spójnych procedur dotyczących diagnostyki sprężarek tłokowych o mocach poniżej 100 kW.
The article presents problems related to the diagnostics of vibrations in reciprocating compressors driven by motors of less than 100 kW. None of the currently applicable norms concerning the issues of vibration diagnostics broach this subject, and therefore diagnosticians have no reference levels for measured vibration parameters. The present paper focuses on two types of compressors intended for diving purposes and hyperbaric techniques. The paper contains a suggested course of actions at the time of taking measurements. Further suggestions for developing coherent procedures as regards the diagnostics of reciprocating compressors of less than 100 kW have been indicated.

Opis:
In line with current rapidly developing technology, mechanization in industry is increasing. In this case, all components that form a machine are becoming important. Compressor plays an important role in operations of numerous machineries. They are used for increasing pressure by compressing gas. Compressors have various types and especially in industries such as automotive, textile, and manufacturing, reciprocating compressors are frequently used. Reciprocating compressors consist of cylinder, piston, and crank and connecting rod mechanism. These components work by narrowing the volume inside the cylinder and increasing gas pressure inside. In this study, flow structure inside a reciprocating compressor was numerically analysed. For this purpose, models were created for 2 different crank angles of a reciprocating compressor. Simulations were made for different pipe angles of inlet pipe and outlet pipe. Valve openings were kept constant at 6 mm. Input and output angles of inlet and outlet pipes to cylinder was changed as 0°, 30°, 45°, 60° and 90°. As a result, it was determined that as the angle of inlet and outlet pipes changed, general flow structure inside the cylinder changed as well. Especially, there were differences in velocity vectors plotted for input and output of the flow from valve to cylinder.

Opis:
The choice of appropriate additives to alternative type of fuels determines the basic problem related with diversification of fuels used to the internal-combustion engines. The research micro engine with swept volume of 165 mm3 and the rotational speed reaching 25000 rpm was fuelled with various liquid fuels of the methyl and ethyl alcohol base. To the alcohol, additives were added with various percentage compositions, such like castor oil and nitro methane. In the fuel system the mixer of fuel with air was applied, that permitted on supply with the liquid fuel, but the composition of the fuel-air mixture was controlled with the quantity of supplied air. Registered was the graph of compression pressure in mini combustion chamber, the maximum power and shaft output torque was measured with the different composition fuels supplied to engine. Research proved that not only alcohol type applied as fuel, but also above all percentage participation of additives to the fuels influenced most on the micro engine work parameters. For the same type of alcohol, but with the different additives, the maximum power and the maximum torque differed significantly. For the micro engine of this type, the best fuel was based on the methyl alcohol and has composition of 60% methanol as fuel, 15% nitro methane (CH3NO2) as fuel additive and 25% of lubricant - castor oil. Article presents the design of the power shaft output micro engine, tested fuels, exemplary graphs of compression pressures in mini chamber on the prototype of a miniature power shaft engine, graphs of the rotary torque and of the engine power of supplied with various fuels.

This article presents selected results of investigations on adverse events of ships throughout one year. The investigations included mainly merchant vessels used to transport bulk material and heavy objects. Ships have been divided into functional systems and elements and into navigational and machine parts. An attempt was made to classify the causes of accidents and evaluate material losses. The quantitative analysis of the causes of the events leads to different conclusions than those reached on the basis of the analyses of losses. Although the failures on-board the vessel occurred more frequently, the costs of machine adverse events were larger. The most critical consequences was fire of a ship caused by loosening of the bleed screw of the fuel filter. Auxiliary engines of the vessel were operated in different external and internal conditions, and were fed by distillation fuel. As a consequence, the evacuation of the crew and fire suppression were required, using the CO2 installation of the ship. The ship was stopped and deprived of its primary sources of electric energy. An analysis of the event was along with the elaboration of a plan of preventive measures. The results should be useful for selecting the monitored diagnostic objects of vessels.

Opis:
Monitoring and diagnostics systems of machinery are increasingly used in many industries. Generally, these systems are responsible for such a machinery like steam turbines, pumps, fans, etc. The increase in efficiency as well as the growing interest of diagnostics systems has expanded the potential markets to other related industries such as mining or metallurgy. This paper presents efficient monitoring methods of machinery generating high vibration signal disturbances. The results have been developed by a diagnostic team, monitoring a reciprocating compressor, which is located on the Baltic Sea oil rig. Important feature of the compressor is existence of strong impacts in the vibration signals. These impulses introduce strong distortion to the signal spectrum. The paper shows that different faults require specific diagnostic methods. The paper shows example of selection of such a method. It is the application of the enhanced resolution envelope analysis for detection of the bearing faults.
Systemy monitoringu i diagnostyki maszyn są coraz powszechniej stosowane w wielu gałęziach przemysłu. Są odpowiedzialne za pracę takich maszyn jak turbiny parowe, pompy, wentylatory i wiele innych. Powiększająca się skuteczność oraz wzrost zainteresowania systemami diagnostycznymi spowodował poszerzenie grona odbiorców na inne pokrewne gałęzie przemysłu takie jak przemysł wydobywczy i hutniczy. Niniejszy artykuł przedstawia efektywne metody monitorowania stanu technicznego maszyn charakteryzujących się silnymi zakłóceniami sygnału drganiowego. Wyniki opracowane zostały przez zespół diagnostów monitorujących kompresor tłokowy, który znajduje się na platformie wiertniczej na Morzu Bałtyckim. Charakterystyczną cechą pracy kompresora jest obecność bardzo silnych impulsów. Impulsy te wprowadzają silne zakłócenia widma sygnałów drgań. W artykule pokazano, że w zależności od typu uszkodzenia konieczny jest dobór specyficznych metod diagnostycznych. Artykuł przedstawia przykłady zastosowania analizy obwiedni o podwyższonej rozdzielczości do wykrywania uszkodzeń łożysk tocznych.

Opis:
Process of development of vehicles is nowadays preceded by extensive modelling tests, which allow evaluating influence of applicable design solutions on future utilitarian parameters of the vehicle. Here, estimation of vehicle's dynamics by measuring of acceleration time from 0 to 100 km/h can be an example. Similar, maximal speed, pollutants emission or fuel consumption under speciflc conditions of vehicle's operation can be the example. Modelling research allow to shorten time of introduction of new vehicle for production significantly. Most eager group of model used in simulation tests of vehicles, according to short time of calculation, is black box models. They do not take into consideration they cyclic type of operation, however, it is possible to identify fast and simple their coefficients. This work involves description of reciprocating engine tests, which have been done under transient and steady-state conditions. Transient conditions were forced by rapid change of engine control signal. During the tests differences of torque generated by engine under transient and steady-state conditions have been registered for the same control signal. Basing on the received results a new algorithm of transient torque calculation has been proposed. In the presented model value of the transient torque has been combined with the engine control signal and others engine parameters, which deser ibe transient history of the engine. Hence, iterative procedures of the transient torque calculation with declared time step have been implemented.

Opis:
An aim of work was analysing of combustion and ignition processes in chambers with small volume at the use of different sorts of fuels, fuel liquid and air mixtures and fuel gas ones. For experiments, the machine of single compression the cubic capacity of 400 mm3 approx and average piston speeds 4 m/s was used. Investigated physical processes allowed better recognizing processes occurring in miniature- real engines. For the feeding of the machine of single compression, homogeneous mixtures of hydrogen with air, propane with air and mixtures methyl and ethyl alcohol in the stoichiometric relation with air were used. Adequately earlier prepared mixtures warranted the repeatability conditions of the experiment. Experiments effected with the machine of single compression showed small increases of pressure from combustion process. The occurrence this can be explained with significant heat conduction to walls during comparatively long compressing and combustion. In carried research with the machine of single compression with very large ratio surface combustion chamber to its volume, one obtained comparatively low value of the maximum compression pressure. The researches showed that on processes of compression, combustion and ignition, the greater influence had geometry of combustion chamber, average piston speed than sorts applied fuels.

Opis:
In the study of wear behavior of tribo-pairs in reciprocating pumps, the tribo-pairs can be considered as contact pairs consisting of a disc and pin. In this paper, pin-on-disc wear tests were carried out by using two types of cast iron pin specimens with different materials. Additionally, the effects of the lubrication condition, test load, diamond-like carbon (DLC) coating and plateau honing cross-hatch pattern on wear behavior of the tribo-pairs were investigated. Experimental results based on surface topography analysis and scanning elec- tron micrograph (SEM) analysis show that the lubricant and DLC coating have a positive effect on wear resistance of test specimens. Disc specimens of three material types (i.e. ISO 185/JL/250, tin-bronze, zirconia) are able to show good anti-wear behavior. The tribo-pairs composed of spheroidal graphite cast irons as well as implementation of the plateau honing cross hatch on disc specimens have no significant effect on the wear resistance. The Archard model was used to estimate abrasive wear under dry conditions, which was over-predicted compared to the experimental results.

Opis:
The paper presents the specificity of operation of propulsion systems of seagoing ships which causes the need to control the load on them, especially on their engines called main engines. The characteristics of the load on the propulsion systems, especially on the main engines as well as on the shaft lines and propellers driven by the engines, along with the process of wear in tribological joints (sliding tribological systems) of the machines have been described herein. Using examples of typical types of wear (both linear and volumetric) for the tribological systems of this sort, interpretation of states of their wear has been provided with regards to the wear levels defined as acceptable, unacceptable and catastrophic. The following hypotheses have been formulated: 1) hypothesis explaining necessity to consider the loads on the systems under operation as stochastic processes; 2) hypothesis explaining a possibility of considering the processes as stationary; and 3) hypothesis explaining why it can be assumed that a given technical state of any tribological system can be considered as dependent only on the directly preceding state and stochastically independent of the states that existed earlier. Accepting the hypotheses as true, a four-state continuous-time semi-Markov process has been proposed in the form of a model of changes in condition of a propulsion system (PS) of any ship. The model includes the most significant states affecting safety of a ship at sea, such as: s0 – PS ability state, s1 – PS disability state due to damage to the main engine (ME), s2 – PS disability state due to damage to the shaft line (SL) and s3 – PS disability state due to damage to the propeller (P). Probability of occurrence (changes) of the states has also been demonstrated.
