Control units for lubrication system

The control and operation of the lubrication system may be done in three ways, with individual settings as necessary for the given track or vehicle.

The first option is using the control unit of the timer which is capable of operating in 4 independent modes (lubrication, circuit initiation, cyclic circuit blow-cleaning, and service buttons). These modes are selected by pushing buttons and their required durations are set by corresponding switches. The time-switched lubrication cycle consists of two phases, the lubrication phase, and the pause phase. The advantages of the timer are easy operation and small installation dimensions.

Another option of controlling the lubrication system is the automatic track curve detection using the SO-01 curve sensor. It is used to run the wheel flange lubrication of rail vehicles in the automatic mode. The device allows detecting curves of various radiuses based on optimum sensitivity settings.

The control unit JMO represents a fully automated control system with an integrated GPS module. The control unit processes input signals from the vehicle speedometer or a dedicated vehicle velocity sensor, the track curve sensor, and the integrated GPS module; it evaluates the current velocity of the vehicle, its position on the track, and the operating conditions. The data processed by the control unit software is used to control the lubrication system according to the current operating conditions of the vehicle, and to apply optimized quantities of grease. The lubrication is controlled either independently for the right and left sides of the axle with vehicle movement direction identification, or jointly for both sides of the vehicle axle. The control unit JMO consists of three basic parts: the control module, the GPS module, and the display unit.
