Automated lubricating system for cables
A recently granted patent (Publication Number: US11879590B2) discloses a system for lubricating cables, such as wire ropes or ropes, as they are traversed through a container. The system includes a pump that forces viscous lubricant onto the cable, a sensor that generates signals indicating the cable's movement rate, and a pump controller that automatically adjusts the lubricant amount based on the sensor signals. The system can be used with pull-feed devices, where the cable is drawn through the container, and features manual override controls, potentiometers for flow-rate adjustment, and motor-controlled clamping mechanisms to regulate the lubricant application.
Furthermore, the patent describes a method for lubricating cables using the system, involving adjusting the pump's adjustable orifice based on the signals from the sensor to control the lubricant amount applied to the cable. By drawing the cable through the container, the system ensures efficient and precise lubrication, enhancing the cable's performance and longevity. The innovative design of the system, with its integrated sensor technology and automated control features, offers a reliable and effective solution for lubricating cables in various industrial applications, contributing to improved maintenance practices and operational efficiency.
