The following graph shows approximate values for the pressure vs coolant orifice diameters for the TSC 300 and TSC 1000. The graph uses a tool with 2 coolant orifices. These values are approximate, and will vary.
The pressure in the flood coolant system is very low, and is not measured in the control. And the tool does not affect the performance of the flood coolant system. The pressure, flow, and velocity of the flood coolant system is affected by these things :
- Changes to the number or diameter of coolant nozzles.
- Closing or opening the coolant valve.
Other Factors Which Affect the Performance of a Coolant System
Other factors can also affect the performance of a coolant system. The most common factors are:
- The input voltage to the pump.
- A restriction in the inlet to the pump.
- A clog in the coolant hose from the pump to the coolant nozzles (Flood coolant only).
An inlet restriction occurs when the filter is clogged with chips. Inlet restriction can cause cavitation. This can cause the pump to run rough. It can also cause the coolant pressure to increase or decrease quickly. It is important to regularly service your coolant filter and inlet for best performance. When the inlet restriction increases, the pressure, flow, and velocity decrease. In the same way when the inlet restriction decreases, the pressure, flow, and velocity increase.
In flood coolant systems, small chips may get past the chip screen, and become stuck in the coolant plumbing. When this happens, the effect is the same as closing the coolant valve. The most likely place for chips to become clogged is behind the coolant nozzle, or at the connections near the pump.
