Lubricant delivery systems, related methods, and computer program products for facilitating the assessment of operating conditions of one or more lubricant recipients are disclosed. In an aspect, assessment(s) facilitated by the lubricant delivery systems and related methods and computer program products of the present disclosure may be used to maintain a lubricant delivery process that delivers a lubricant supply to one or more recipients in order to minimize or prevent damage. Assessment(s) may be at least partially facilitated by one or more sensing devices that may be configured to detect, measure, or sense one or more operating conditions of at least one recipient in order to identify situations wherein the recipient(s) may be operating without adequate supply, amount, density, viscosity, and/or composition of one or more lubricants. A user and/or computing device may make one or more adjustments to at least one lubricant delivery process to the recipient(s).

There is disclosed a tool for filtering a lubricant to meet a target ISO cleanliness code. The tool includes a skid-mounted integrated filtration system having a pump that circulates a flow of lubricant from an inlet port, through a heater, through a series of specifically sized filters, and past a digital particle counter. The filtration system also includes a user interface and a programmable logic controller (PLC) configured to track outputs from the pump, the oil heater, and the particle counter to monitor a cleanliness of the circulating lubricant. The filtration system also includes a filtration operations server in communication with the PLC and configured to implement a tracking and monitoring software application enabling control of the filtration system from the system itself or remotely through one or more remote user terminals such as a smartphone, a laptop or tablet computer, and the like. Other embodiments are disclosed.

Provided is a grease injection system including a plurality of grease injection devices and a host. The grease injection devices uses control information to output lubricating grease, and output a plurality of pieces of status information. The host receives the pieces of status information from the grease injection devices, and generates the control information based on the pieces of status information.

There is provided a bearing lubrication application control system which comprises a digital controller device operably coupled to a lubrication meter and a computer readable medium reader. As such, during lubrication application, the digital controller device is configured for reading bearing data from bearing computer readable media associated with each bearing and also recording an applied lubrication volume for each of the bearings. As such, for a subsequent lubrication application, the digital controller device is configured for calculating a dynamic lubrication schedule for each of the bearings wherein the schedule comprises at least an appropriate lubrication volume to be applied calculated at least according to the stored apply lubrication volume for each of the plurality of bearings.

A gas turbine engine including a lubricant system defining a lubricant circuit through which a lubricant flows in fluid communication with a bearing assembly of the engine. The lubricant system selectively bypasses thermal communication of the lubricant and a heat sink based at least on a temperature of the lubricant within the lubricant circuit.

A lubrication system includes a progressive distributor that is configured to dispense lubricant to a consumer. The lubrication system also includes a control device and at least one sensor that is configured to determine at least one lubricant pressure inside the lubrication system. The control device is configured to receive measured values from the at least one sensor and to recognize a lubrication cycle based on the measured values and also to determine an average pressure of the lubrication cycle, to perform a comparison of the average pressure and at least one normal pressure of the lubrication system, and to determine a state of the lubrication system based on a result of the comparison.

A motor assembly includes a shaft, a bearing, at least one fluid channel, a temperature sensor, a lubricant supply pump, and a controller. The bearing defines a bearing interface against which the shaft rotates. The at least one fluid channel is fluidly coupled with the bearing interface. The temperature sensor detects a temperature of the bearing. The lubricant supply pump is fluidly coupled with the at least one fluid channel to transport lubricant from a lubricant supply to the bearing interface via the at least one fluid channel. The controller receives the bearing temperature from the temperature sensor, determines a difference between the bearing temperature and a supply temperature of the lubricant, determines a lubricant flow rate based on the difference, and transmits a control signal to the lubricant supply pump to cause the lubricant supply pump to transport the lubricant to the bearing interface at the lubricant flow rate.

A lubricant deterioration detection device of the present invention includes a gas sensor that selectively detects a carbonyl compound.
