Working Circuit
Circuit Principle
Chemical Injection System = Liquid boost pump + Valves + Gauges + Tubes + Cart
Composition of Standard Chemical Injection System
Liquid boost pump (DGG/DGGD/2DGGD three series for choosing)
F.R.L combination for driven air (adjust air pressure + add lubricating oil + filter function)
Driven air switch, driven air pressure gauge
High pressure needle valve, High pressure gauge, unload valve, Interconnecting pipes, etc.
Trolley ( There types options)
