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, with at least one sensor generating signals indicating the cable's rate of movement. A pump controller then automatically adjusts the amount of lubricant applied to the cable based on these signals. The system also features a manual override control on the pump, a potentiometer for adjusting the flow rate, and an adjustable orifice controlled by a motorized clamping mechanism to regulate the lubricant amount effectively.
Furthermore, the patent describes a method for lubricating cables using the system, where the pump's adjustable orifice is adjusted based on signals from the sensor to control the lubricant application. The cable is drawn through the container, ensuring proper lubrication as it moves. This innovative system offers a precise and automated way to lubricate cables, enhancing their performance and longevity. The inclusion of various control mechanisms and sensors allows for efficient lubricant application tailored to the cable's movement, making maintenance easier and more effective in various industrial applications.
