摘要： A lubrication system comprises a lubricant reservoir, a motorized pump, a follower plate, a stationary rod, a movable sleeve, and a flexible connection. The motorized pump is disposed to pump fluid from the lubricant reservoir to lubricant work lines. The follower plate is situated within the lubricant reservoir. The stationary rod has a colored indicator portion. The movable sleeve disposed concentrically about the stationary rod. The flexible connection extends between the follower plate and the stationary colored rod, such that the flexible connection pulls the movable sleeve away from the stationary rod to reveal the colored indicator portion as the follower plate drops towards a bottom of the lubricant reservoir.

摘要： A motor control system for a lubricant pump motor comprises a pump system power input, a motor drive, a current sensor, a lubrication controller, and a drive controller. The pump system power input is configured to supply system power. The motor drive is configured to drive the lubricant pump motor using the system power. The current sensor is disposed between the pump system power input and the motor drive to sense an input current of the system power. The lubrication controller configured to provide motor activation signals. The drive controller is disposed to receive the motor activation signals via an isolated digital input, and to control the motor drive as a function of the sensed input current and a user-defined current set-point, in response to the activation signals.

摘要： A fuel pump is disclosed wherein a substantially cylindrical plunger bore is provided with an annular drain groove fluidically coupled to a drain duct. A pump plunger is driven by a drive system located in a separate mechanical compartment that holds a reservoir of lubricating oil. An annular seal is provided adjacent the drain groove substantially at the end of the bore and retained in position by a seal support. Exemplary embodiments provide the drain groove and seal as being positioned immediately adjacent one another so that the seal forms a lower wall of the drain groove.
