Once the tip cap is eliminated, the diaphragm and related plate are eliminated (Figure 9(d)). Then, a pin retaining the pump shaft is eliminated (Figure 9(f)) and the pump shaft is eliminated (Figure 9(g)) and threaded onto the actuator push rod (Figure 9(h)). The pump shaft is then put in again into the pump 12 with the actuator 52 connected thereto (Figure 9(i)), and the retaining pin is re-put in (Figures 9(j) and 9(k)).

Finally, the pump mounting surface 59 is positioned adjacent to the pump 12 so that the bores are lined up and the actuator 52 is fastened to the pumpl2 utilizing nuts and bolts (Figure 9(mO)). Alternatively, the power supply can be a wind turbine (not proven), or a fuel-powered electric generator (not shown), or an electrical power grid. The latter is particularly helpful for those pumps which aren't located in remote regions. The level data is then analyzed by the operator to determine the expenditure of every properly, and by the chemical supplier for scheduling refill deliveries based on the rate of injection.

If there is no electric present within the coil, the pressurized chemical pushes the metal ball onto the valve seat inflicting a tight contact between the ball and the rubber washer, which lastly shut down the flux of chemical. Previous studies have pointed out that there are advantages to realizing website-particular and variable-rate software of pesticides .

The SCADA system is typically remotely located from the well website, and in such case the discreet status sign output is to a RMS 242 connector that communicates with the distant SCADA system. The RMS 242 connection allows for manual or automated distant management of pump charges of the management system 10. Referring now to Figures 9(a) to (m), a way of installing the actuator fifty two onto the pump 12 is illustrated. Figures 9(a) and (b) show a conventional methanol A CANAN_LAW\ \1 11 injection pump with its diaphragm meeting in place. Referring to Figure 9(c), set up of the actuator fifty two begins by eradicating the tip cap of the pump's diaphragm meeting.


The efficiency of the closed-loop controller also can be verified from the output of the EC sensor as proven in Figure 12, in which the readings are from the identical check displayed by a strong line in Figure 9. Comparing these two curves, the flowmeter output and EC sensor change simultaneously.

When electric current flows through the copper coil, a strong magnetic area is generated contained in the metallic cavity primarily based on the electromagnetic induction principle, then the metal ball is pushed aside by the magnetic subject. Thus an entry for the chemical from the inlet to the orifice of the valve seat is formed, through which pressurized chemical can be injected.

Their process for monitoring the tank ranges was performed by devoted personnel driving from one properly to the subsequent. The worker manually logs every tank level on paper after which reports to the operator’s chemical supplier upon return to the office. The RRV used within the DNIS may inject chemical with move rates starting from zero.1 mL/min to greater than 30 mL/min, which covers most spraying operations within the area. Output of the EC sensor when the desired output of the flowmeter was set at eight V (equal to a desired chemical circulate rate set at eleven.8 mL/min).

Although they've opposite developments (the calibration of the EC sensor is unfavorable correlative, the higher the move fee and subsequently the conductivity, the decrease the output voltage), each might be used to point the circulate rate. After the circulate price achieved a gradual state, the EC values had been analyzed. The consistency and stability of the EC values indicate the focus of the salt resolution was stable, therefore the move fee metered by the closed-loop controller was constant.
