TARGET. The purpose of this work is to develop a method for diagnostics of equipment of sucker rod pumping units (SRPU) during operation according to the parameters of the wattmetrogram. A wattmetering module is used as a measuring element, the developed software in the MatLab software package serves as a tool for processing vibration signals. The technical condition of the sucker rod pumping unit is analyzed by the parameters of the wattmetrogram and the amplitude spectra of the object under study, formed using the fast Fourier transform procedure in the MatLab software environment.METHODS. The wattmetering method allows you to control the sucker rod-pumping unit during its operation under voltage. This control method is highly accurate, sensitive to developing defects, and allows the use of computer technologies for signal processing and analysis.RESULTS. The wattmetering method is fully disclosed. The construction of the spectrum is considered. The relationship between the wattmetrogram and the dynamogram has been established. The removal and evaluation of experimental data from the operating sucker-rod pumping unit during its operation was carried out. A wattmetrogram and a dynamogram were built, a spectrum was also built, which showed the presence of defects in this installation.CONCLUSION. This method of wattmetering with the MatLab software allows you to monitor the technical condition of the sucker rod pumping unit according to the amplitude-frequency characteristics of the wattmetrogram parameters.

Establishing and then solving the movement equation of the mechanism of the conventional sucker rod pumping units allows determining the variation on the cinematic cycle of the angular speed of the cranks as a dynamic response to the motor and resistant actions on the component elements. The evaluation as accurate as possible of the dynamic response depends on a more precise determination of the variation on the cinematic cycle of the synthesis parameters that occur in the movement equation of the mechanism of the pumping units. In the paper is established the movement equation of the mechanism of the conventional pumping units and are presented a series of results regarding the variation on the cinematic cycle of some synthesis parameters in the case of the mechanism of a C-640D-305-120 pumping unit. Experimental records have been processed with the Total Well Management program and the simulations have been performed with a computer program developed by the author using the Maple programming environment.

In the kinetostatic study of the mechanism of the sucker rod pumping units, the cinematic motion parameters of the elements are considered to be known, assuming that the cranks have a constant angular velocity imposed by the operating functioning conditions of the pumping unit. The paper analyzes the dynamic response of the mechanism of these pumping units, which implies the determination of the variation of the angular acceleration of the cranks during the operating cinematic cycle. A series of results regarding the determination of the variation of the angular acceleration of the cranks during the cinematic cycle in the case of the mechanism of a C-640D-305-120 pumping unit are presented. The obtained results are checked by comparing the experimental curves of variations of the acceleration at the polished rod with those obtained by simulation using a computer program developed by the authors in which the angular acceleration of the cranks was taken into consideration.

It is well known that the bearings of the mechanism of the conventional pumping units are heavily loaded so that their design has to be accomplished very carefully. In this scope the values of the connection forces acting on these bearings has to be determined as accurately as possible. In the paper is presented the kinetostatic analysis of the mechanism of the conventional sucker rod pumping units, obtaining in this way the values of the connection forces in the joints and of the motor moment at the cranks shaft. For processing the experimental records it has been used the program Total Well Management. The simulations have been performed with a computer program developed by the authors using Maple programming environment.

The aim of the research was to verify the impact of selected parameters on the efficiency and organization of chipper operations. The paper analyzes chipping operations in Polish forests with a focus on work site location, overnight chipper location, chipper workload per site, fuel consumption, and work shift duration, as all of these factors may affect operating efficiency. The mean chipper travel distance between sites during a shift ranged from 4.74 km to 9.5 km (chippers moved on average every other day). The mean work shift duration was 12.4 h. At the end of a shift, the chippers traveled on average from 4.2 km to 6.3 km to an overnight location. At the beginning of a workday, the chippers were dispatched to sites at a distance of 2.5 km to 4.0 km. The average fuel consumption of the forwarder-mounted chippers was 16 L/h and that of the truck-mounted chipper was 7.7 L/h. It was found that the following actions have a decisive influence on the effectiveness of the operation of the chippers: determination of the size of individual tasks and the deployment of successive forest areas, indication of the proper location of the machine base, and the method of accessing the forest area.
