Pneumatic control metering pump

Product Categories: Metering pumps

Company Profile Tel ：023-61727399 Fax：023-65305486

Product Description:

Consisting of metering pump, pneumatic positioner, directional valve, pneumatic motor, silencer set, mechanical controlled stroke valve, position feedback set, smart controller, etc.

The pneumatic servo regulating mechanism is an automatic regulating mechanism using compressed air as power source. When the control signal from the regulating instrument changes, the discharge pressure of the pneumatic positioner varies accordingly. The varied pressure, after comparison, makes the directional valve work; the compressed air then enters the pneumatic motor via the directional valve and cut-off valve to drive the stroke adjusting mechanism. The feedback rod sends the position signal back to the pneumatic positioner. When the position feedback signal corresponds to the pneumatic signal, the discharge pressure of the pneumatic positioner and the counter pressure of the directional valve achieve balance, the directional valve is closed and the stroke adjusting mechanism stops, thus realizing accurate positioning.

To trace input signals, stepless regulation of stroke, automatic control of capacity from 0 ~ 100%, closed-loop control, switchover of manual and automatic operations
