Abstract

A system (300) for indicating a non-ideal condition of a drum (120, 220) of a compressor (100, 200) comprises a sensor (302) connected to the drum (120, 220) of the compressor (100, 200) which generates a signal (304) indicating a current vibration amplitude of the drum (120, 220). The system (300) also includes a controller (320) with one or more memories (322) and one or more processors (324). The one or more processors (324) receive the signal (304) from the sensor (302), which indicates the current vibration amplitude of the drum (120, 220), compare the current vibration amplitude with a nominal range (R1) for the vibration amplitude of the drum (120, 220), determine whether the current vibration amplitude is outside the nominal range (R1) for the vibration amplitude, and generate an output signal (330) if the current vibration amplitude is outside the nominal range (R1) for the vibration amplitude. The output signal (330) indicates the non-ideal condition of the drum (120, 220) of the compressor (100, 200).

Description

Technical field The present disclosure relates to a compressor and in particular to a system for indicating a non-ideal state of a bandage of the compressor and a method for indicating the non-ideal state of the bandage of the compressor. State of the art A compactor is typically used to compact materials such as asphalt, sand, aggregates, rock, clay, concrete, or other similar materials. The compactor includes one or more drums that contact the materials to be compacted. The drums may have a smooth outer surface or they may be padded. Each drum is equipped with a vibration system that sets it in motion at a desired frequency and amplitude to compact the materials. Compressor drums can wear down over time through interaction with the materials being compacted. For example, cracks in the drum with the smooth outer shell can propagate, leading to a malfunctioning compressor and/or an inefficient compaction process. Furthermore, wear on multiple pads on padded drums can result in uneven contact with the compressor and uneven compaction. In some cases, materials being compacted by the compressor can accumulate on the outer shell of the drum or on the compressor's pads. This material accumulation can increase the drum's mass, which in turn can reduce its vibration amplitude. A decrease in vibration amplitude can reduce the effectiveness of the compaction process and require a greater number of passes to achieve the desired compaction level. US registration number 2020/0378554 This describes a machine that includes a compressor drum, a control unit, and a dispensing device. The compressor drum contains a vibration system with at least one bearing that supports the rotation of the vibration system within the compressor drum, and lubricant that is held by this bearing. The control unit is configured to monitor at least one physical property of the vibration system over a specific period and, based on this property, to predict the remaining service life of the lubricant. The dispensing device is configured to generate an output indicating the remaining service life.
