Low Pressure Water System

Cutting water inlet system provides cutting water flow and pressure to the intensifier. The low pressure inlet water system components include input water filter components and booster pump. Connected to the PLC with the pressure switches and temperature switches, it can monitor the inlet cutting water condition. If it goes beyond the inlet water requirements, it will shutdown the pump automatically.
Input cooling water flows through the oil/water heat exchanger (cooler) in order to control the temperature of the hydraulic oil. Then the cooling water flows out from the cooling water outlet into the drain or into a customer to provide water cooler. This path make up to the chilling circulation.
