Apparatus and method for lubricant condition control and monitoring

A volumetric lubricant dispensing apparatus for delivering a precise volume of lubricant, such as oil, to a rotating machine element. The delivery mechanism includes a piston and cylinder assembly. A plurality of sensors are utilized to record operating conditions of the machine, element, environment, and lubricant. The apparatus is controlled either manually or with the aid of a controller unit such as a microprocessor. The output from each sensor is inputted into the microprocessor wherein an algorithm computes an responsive output. The responsive output is sent to the piston and cylinder assembly, which maintains an optimum lubricant condition within the reservoir wherein a rotating machine element located. Alternatively, for the purpose of qualitative control, the present invention may be described as a system intended for controlling lubricants, both mineral (natural) and synthetic based by measuring the condition characteristics of the lubricant. Some condition characteristics may include water or moisture content (the content could be any liquid, e.g., solvents like ketones are known to change condition characteristics like viscosity) and viscosity. Viscosity is related to temperature, therefore, temperature correlation to viscosity is helpful to provide relative indications for condition characteristics like lubricant flow.

InactiveUS20140188404A1High pressure environmentEngine temperatureEngine pressureEngineeringLubrication
This invention encompasses embodiments for multi-modal integrated simultaneous measurement of various aspects of fluids contained in circulating systems such as automotive reciprocating engines and vehicle transmissions. These circulating systems perform constant internal lubrication, and heat and contaminant removal to protect the internal moving parts from the inherent friction and damage in normal operation. Most commonly this is achieved with fluids based on hydrocarbon and / or related synthetics, which, over time, can lose their protective properties, and vary in their performance or breakdown / decay due to internal and external events. Several components within the lubricant fluid can be measured and can provide insight into the efficacy of the system to perform its designed mission. Described herein is a real-time, simultaneous, integrated, multi-modal sensor system for early warning notification.
