Can a variable-frequency motor be used for Naisch pumps?
Thread Content
Our plant uses Naisse pumps for liquid chlorine filling; these pumps are used to handle chlorine gas within the filling lines and to detect any residual chlorine gas in the cylinders. To save energy, we are considering switching to variable-frequency control for regulating the suction force at the inlet – is this feasible?
It is not feasible from the perspective of safety and environmental protection; when the inlet pressure increases and the frequency conversion rate rises, it is easy to cause chlorine leakage, which can affect the health of employees.
