An automated zipper manifold with remotely and independently controlled and monitored valves, wherein second pressure transducers are positioned on the zipper manifold and are configured to determine a flow analysis across the valve.

An automatic lubricator for lubricating an object is described, which comprises a housing with a coupling section configured to couple with a lubricant container containing a lubricant, wherein the lubricant container comprises a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. The lubricator further comprises an electric motor configured to drive the rotatable shaft of the lubricant container during at least one lubrication action, such that at least a part of the lubricant is dispensable from the lubricant container during the at least one lubrication action, and a power supply configured to supply the electric motor with a supply current during the at least one lubrication action. The lubricator further comprises a control circuitry configured to acquire a current signal indicative of the supply current over time during at least a part of the at least one lubrication action, determine a periodicity of the acquired current signal, and determine, based on the determined periodicity, at least one lubrication parameter indicative of the at least one lubrication action.

A lubricant supported electric motor includes a stator presenting an outer raceway and a rotor extending along an axis and rotatably disposed within the stator. The rotor presents an inner raceway disposed in spaced relationship with said outer raceway to define at least one hydrostatic support chamber disposed therebetween. A lubricant is disposed in the hydrostatic support chamber for supporting the rotor within the stator. A monitoring port is disposed in fluid communication with the at least one hydrostatic support chamber, and a sensor is coupled with the monitoring port for monitoring an operating characteristic of the lubricant disposed in said at least one hydrostatic support chamber. This monitored operating characteristic is then used to determine a real-time operating condition of the lubricant supported electric motor.

In a method of greasing a decanter centrifuge, each beating of the decanter centrifuge is located in a bearing housing and at least one bearing housing has a grease flow meter. The grease flow meter is connected to a control unit. The method includes generating a greasing operation when the operating time of the decanter centrifuge is equal to or exceeds a specific time interval between greasing operations. The greasing operation includes generating a start signal in the control unit, measuring an amount of grease injected into the bearing housing by using the flow meter, and generating a stop signal in the control unit when the amount of grease injected into the bearing housing is equal to or exceeds a specific amount of grease to be injected at each greasing operation.
