5.13 FLOW RATE ADJUSTMENT SYSTEM
Flow rate adjustment is continuous and regular and can be carried out either with the pump running or at rest. Anyhow the action it is
easier when pump is running, especially in case of large diameter plunger pumps.
5.13.1
Manual adjustment via graduate knob and linear vernier
Standard version provided when it is not specifically requested a particular adjustment system.
The graduated knob, turning on a fixed vernier, runs on a linear scale sub-divided from 0 to 10. Zero (0)
on the knob lower edge is a reference index for setting the adjustment system to a desired flow rate
percentage value.
5.13.2
Manual adjustment via handwheel with gravitational dial
Manual version as an alternative to the "base" version (supplied upon request).
Easy and quick manual adjustment combined with precise, clear and immediate reading. The dial has a
percentage scale (from 0 to 100) and is equipped with two pointers. Each turn of the handwheel
corresponds to an adjustment change of 1% (millesimal reading).
ATTENTION: Adjustment via handwheel with gravitational dial indicator can be
decalibrated during transportor handling due to sudden accelerations, shock or capsizing.
Proceed as follows to reset decalibrated adjustment:
- start up the pump and extract the gravitational dial from the handwheel by means of a screwdriver;
- turn the handwheel counter-clockwise, stopping when the plunger remains STOPPED (despite the motor running);
- turn the gravitational dial by hands bringing the pointers to 0%, then reposition the dial in the handwheel.
5.13.3
Automatic adjustment by means of actuator
The adjustment system can be automated (upon request) via the application of an electric or pneumatic actuator.
For information on actuator operation consult its specific operating manual.
5.14 INTERNAL SAFETY VALVE ON HYDRAULIC OIL CIRCUIT
All X9 pumps are equipped with an internal safety valve in the hydraulic circuit, located in the expansion tank (see the figures in
"Hydraulic system oil filling").
