초록 ▼

A metalworking fluid central system through which aqueous cutting fluid recirculates through a plurality of machine tools is provided with an in-line fluid condition monitor which produces real-time fluid composition data for use in controlling the condition of the fluid. Four sensors simultaneously measure temperature, pH, dissolved oxygen and conductivity at hourly intervals and the data is stored in a computer module linked to the monitor. A plurality of diversely located plants are similarly equipped. A computer at a remotely located central monitoring facility selectively connects to the computer modules at the various plants through modems and a telephone system to collect the data daily. The data is analyzed at the central facility and dimensions are made manually and automatically to add components to the fluid at the respective plants or to take other corrective action. Commands and recommendations are communicated to the computer modules at the respective plants where they are manually and automatically implemented by the operation of valves, pumps or other devices or methods to modify the make-up of the fluid in the central system.

대표청구항 ▼

A method of maintaining the condition of an aqueous metalworking fluid at a metal working location having located thereat a plurality of metalworking machines, a central reservoir containing a volume of the aqueous metalworking fluid sufficient to service the plurality of machines, and means connected to the machines and the reservoir for circulating fluid through the machines and the reservoir, the fluid being made up of components that include a lubricant and water and being used under conditions that will support contaminating biological activity within it, the method comprising the steps of: monitoring, in-line with the fluid circulating means, a plurality of different components of the fluid and producing in real time for each monitored component a measurement signal responsive thereto, including an oxygen measurement signal responsive to the dissolved oxygen content of the fluid and a pH measurement signal responsive to the hydrogen ion content of the fluid; generating, in response to the oxygen measurement signal and the pH measurement signal, at least one monitoring signal carrying information of the pH and oxygen content of the fluid; analyzing the pH and oxygen content information carried by the monitoring signal; and modifying, in real time, the content of a third component of the monitored fluid in response to the analysis to control the biological activity therein.
