Operations
Chemical Injection System
The chemical injection system is unique in that it
utilizes the pressure spikes generated by the high
pressure solution pump to move chemical into the main
solution stream. The high pressure spikes move the
diaphragm in the chemical pulse pump forcing small
amounts of liquid chemical to be moved in a single
direction of flow with the aid of two check valves.
The chemical is drawn from the container, and through
the flow meter, which indicates rate of flow. The
chemical then moves to the chemical pulse pump
where it is pressurized.
After being pressurized by the chemical pulse pump the
chemicals are fed to the control valve which directs the
chemical either into a bypass loop to purge air from the
system or in to the solution metering valve.
The metering valve creates an orifice allowing the
correct amount of chemical to enter the outlet manifold.
The outlet manifold assembly is complete with a check
valve that will not allow the chemicals to travel
upstream into the plumbing system of the unit.
The chemicals are then mixed with hot pressurized
water to make a solution for the chosen cleaning
application.
