An oil mist generating system and monitoring method is shown and described, including pressurized air and oil supplies connected to a mist generating head. Sensors are provided for monitoring current values of the system operating parameters and for generating data signals based on the monitored values. A data processor functionally connected to the sensors generates signals based on the data input, such as an alarm signal if one of the monitored values is beyond the extremes of a predetermined range of values indicative of a fault condition. A visual display device displays programmed messages based on the signals generated by the data processing means. If a fault condition exists, the displayed messages aid the user in diagnosing and correcting the reason for the alarm signal. The user may manually request further programmed messages using a keypad, which messages direct the user to take predetermined actions to troubleshoot the problem and maintain the system at an appropriate operating level. The data processor also initiates or terminates steps in a system start-up sequence in response to the monitored values. A computer-compatible, two-way communication port is also provided for two-way communication between the system and a remotely located computer. The system and method thus guides a user through a safe, effective start-up and provides on-line troubleshooting while monitoring operation. The oil mist generating system may also include a stand-by unit having a mist generating head, wherein the regular and stand-by units share common connections to air supply, oil supply an mist outlets. Three-way valves for controlling the connections providing for a simple and safe switch-over to the stand-by unit during times of temporary shutdown.

Oil mist generating system and method

An apparatus for generating a mist for use in a centralized, pressurized gas-driven mist generating system is disclosed in which a frame member is formed with a mist generating passage, a pressurized gas inlet passage connecting with the mist generating passage, and a liquid inlet passage connecting with the mist generating passage. The mist generating passage is adapted to receive a gas-operated venturi nozzle having mist flow rates ranging from about 0.1 cfm to about 65 cfm. A pressure relief valve for relieving excess gas pressure is also disposed in the mist generating passage and adapted to open if the gas pressure in the mist generating system reaches a predetermined level. The mist generating apparatus further comprises an adjusting member, such as a needle valve, disposed in the liquid inlet passage and extending externally of the frame member to a position accessible for adjustive manipulation by an operator for controlling the liquid flow rate and adjusting the ratio of liquid-to-gas in the mist. A liquid supply tube, received in the liquid inlet passage of the frame member, a liquid heater and a liquid level detector are all part of the mist generating apparatus. An electrical conduit passing through the frame member for receiving and conveying power supply wires to the frame member and an electrical terminal strip fastened to the frame member for electrical connection requirements of the mist generating system are also provided. A reservoir is sealingly secured against the frame member for containing the liquid supply. A reservoir filling passage is formed in the frame member having an end opening into the reservoir and the other end opening externally of the frame member. For large reservoirs, a plurality of mounting ports for the frame member are provided for accommodating multiple heads for redundant or specialized functions.
