GEAR PUMP QUANTITATIVE CONTROL SYSTEM

A. SYSTEM FEATURE:
control system adopt PLC programmable control model, equipped with progressive human-computer interface, can automatic & manual control on high viscosity medium dosing, quantitative filling, temperature controlling, liquid level controlling, pressure controlling, motor rotating all around, the control system can exploit the gear pump’s advantages on precision measurement to the full.

B. SYSTEM MODULARS:
■   Operation modular: PID digital display, PLC programmable human-computer interface
■   Delivery modular: DX gear pump
■   Executing modular: servo motor+ speed reducer, variable frequency motor+ speed reducer, electrical heating rod, pressure sensor, liquid level switch
■   Alarming modular: alarm under special conditions (sound/light)

C. FUNCTION NOTES:
■   Default flow pump-off (quantitative control)
■   Outlet liquid level control pump on/off
■   Tele-control pump on/off
■   Inlet liquid level control pump on/off
■   On-spot real-time flowrate/total flowrate display
