Abstract

The invention relates to a machine tool industry, in particular to methods for supplying a coolant fluid (LCL) during their thermal activation. The aim of the invention is to increase the cooling efficiency and reduce the consumption of coolant. When the valve 4 is closed, the water coolant of the feeder 1 is filled and hermetically sealed with the cover 2. The valve 4 is opened and the steam generator 5 is filled with the coolant until the coolant closes the pipeline 3. The heater 6 is turned on, the steam is heated to 101-103 ° C under pressure of 0.01-0.02 MPa and feed it through the pipeline 9 into the nozzle 10. 1 Il., 1 tab.

The invention relates to a machine tool industry, in particular to methods for supplying a coolant fluid (LCL) during their thermal activation.

The purpose of the invention is to increase cooling efficiency and reduce the consumption of coolant.

The drawing shows the setup diagram for the implementation of the method.

The installation includes a feeder 1 with an airtight cover 2, connected to it through a pipe 3 with a crane 4, a steam generator 5 with a heater 6 and a heating controller 7, a safety valve 8 installed on the steam generator 5 and a coolant supply pipe 9 to the nozzle 10.

The method is carried out as follows.

When the valve 4 is closed, the water coolant of the feeder 1 is filled and hermetically sealed with the lid 2. The valve 4 of the pipeline 3 is opened and the steam generator 5 of the SOC is filled until it closes the pipeline 3. The heater 6 is turned on, the coolant in the steam generator 5 is heated to temperature intense vaporization (boiling). The intensity of vaporization is regulated by the regulator 7. The resulting

the steam overheats to a temperature of 10-1-103 ° C under a pressure of 0.01-0.02 MPa and is fed under this pressure through conduit 9 to the nozzle 10. As the CO / K boils out, the opening of the conduit opens. The coolant flows by gravity from the feeder 1 to the steam generator 5.
