- Check the system for reconditioning the cooling lubricant
Orientation
Cooling and cleaning equipment for cooling lubricants is used where reconditioning
of the cooling lubricant is necessary. Here, in order to achieve high availability of the
cooling lubricant, the cooling lubricant is filtered (e.g., using edge gap filters or
vacuum rotation filters) and also cooled using coolers to a certain preset
temperature.
Here, the filters, pressure and temperature sensors, valve functions and fluid lines of
the devices must be checked.
Similarly, the supply lines to the machine and the fluid lines in the machine must be
checked for damage such as abrasions or kinks or leakage.
For all work in connection with operating materials, the information in
the data sheets of the respective manufacturers and the information
in the document Notes on Operating Materials must be observed.
Due to different requirements and/or specifications of the respective
manufacturers, be sure to review the respective manufacturer's
documentation!
Requirement
To determine the concentration of cooling lubricant in the cooling lubricant, a
measuring device (refractometer) is necessary.
Procedure
1. Evaluate the overall impression of the system.
2. Visual inspection for leaks.
3.
Filters are hazardous waste and must be disposed of in a
controlled manner.
Replace filter.
4. Check and potentially adjust float switch settings.
5. Check and potentially adjust temperature sensor settings.
6. Check and potentially adjust pressure sensor settings.
