Content available Diagnostics of the Passenger Lift Winch
EN
The proposal of the diagnostics methodology for the passenger lift winch is presented in this article. The selected device is tested against the emitted volume of sound and vibrations observed in the regular operation (driving operation as per agreed testing sequence). Thermal images are prepared to catch incorrect operation of the winch mechanisms. On the basis of received measurements for the sound volume, accelerations (vibrations), the analysis of vibrations frequency and thermal images, the attempt is made to diagnose the winch condition and to indicate possible reasons of the malfunctions condition.

The energy performance and operational characteristics of the passenger lift investigated in this study were based on energy consumption data registered throughout the normal duty cycle. An overview is provided of available methods employed to evaluate the energy uptake of passenger lifts, relying mostly on energy consumption measurements taken on a real object over an idealised reference duty cycle. Measurement data were used to determine the energy efficiency rating of the lift during the trip cycle and in the standby mode and the energy demand levels, which are then to be compared with measurement results obtained under the service conditions.

This paper is focused on the data acquisition system for registering parameters of lift installations in terms of their energy efficiency (energy take by the entire installation, by the drive unit, the lift car elements, control unit, lift car door, halt doors) as well as operational parameters (lift car loading, ride direction, distance covered, kinematic parameters, service time). The main components of the measurement system (transducers) are briefly described and the results are given as registered operational and energy parameters of the lifting installation measured over the weekly duty cycle, defined by the users’ demand and usage.

Artykuł prezentuje opracowany na Akademii Górniczo-Hutniczej w Krakowie, w Katedrze Transportu Linowego, system diagnostyczny do pomiaru prostoliniowości prowadzenia kabin dźwigów osobowych. Zostały w nim opisane możliwości sprzętowe i programowe wspomagające wybór położenia elementów ciągu prowadniczego kabiny w rozpatrywanym szybie dźwigu osobowego. Przedstawiona metoda pomiarów prostoliniowości zapewnia wysoki poziom bezpieczeństwa, krótki czas realizacji, niskie koszty przeprowadzania badania i aparatury pomiarowej oraz pozwala uzyskiwać wyniki obarczone małym błędem.

The article presents developed, at AGH University of Science and Technology, diagnostics system used for rectilinearity measurements of guiding rails in passenger lifts. There were described programmed and hardware possibilities supporting the choice of a position of elements of cabin guiding rails in considered shaft of passenger lift. This method of rectilinearity measurements ensures high level of safety, short term of realization, not excessive costs of conducted examinations and instrumentation, as well as the results with low errors.
