9. operating system To use your 6000 Series Pump System effectively you must know what you want to do with the fluid you are pumping and how to utilize Pump Works to accomplish this The 6000 Series Pump System uses operating modes to pump fluid in a wide variety of ways First the user must decide whether to choose an independent or paired operating mode Ifa single stroke volume is sufficient for the desired flow then independent cylinder operation is possible If multiple stroke volumes are needed but discontinuous flow is acceptable then an independent cycled mode may be a good choice If smooth continuous fluid flow of more than one cylinder stroke volume is needed then paired cylinder operation is required The second decision is whether the flow should be at constant rate or constant pressure For constant pressure operation decide if the output pressure of the pump is to be held constant or if the pressure across a portion of the flow loop is to be held at a constant constant delta pressure Constant delta pressure requires the user to interface an external delta pressure transducer to the CN 6000 Pump Controller interface connector in order for the controller to be able to read this pressure Decision number three involves how you want fluid to flow in relationship to the pump Will the flow of fluid be out of the pump delivering fluid or into the pump receiving fluid Once you decide what you want the pump to do you then need to

When the pump cylinder reaches the Max Extend position close the deliver valve open the fill valve switch the direction to Retract Re start the pump cylinder and as the piston retracts fluid will be drawn into the cylinder barrel Then on the next Extend stroke mostly air is still delivered out of the fluid outlet fitting If neither air nor fluid is delivered out of the fluid outlet there is probably a leak in the plumbing Repeat this procedure until you reach a piston stroke where no air bubbles come out only liquid End with a Retract stroke The cylinder barrel is now full of fluid and all air is flushed out If you are pumping gas test for bubbles Repeat this procedure for each pump cylinder in your system ending with all pump cylinders full of fluid and the pistons in the Max Retract position 3 5 Quizix 6000 SERIES PUMP MANUAL 3 6 3 6 Pressure Transducer Check Because the pump system can reach extremely high pressures very quickly it is absolutely essential that the pressure transducers be checked carefully To do this use the following procedure l It is assumed that each pump cylinder is full of fluid and each piston is in the Max Retract position Close both valves fill and deliver for pump cylinder 1A using PumpWorks Pump Data amp Controls window Set the flow rate to 10 ml min With the safety pressure still set at 100 psi 700 kPa and the direction set to Extend start the pump cylinder W

C 6000 20K Stroke Volume Typical 550 ml 275 ml 125 ml Chapter 4 PUMP OPERATING BASICS For example a C 6000 5K pump cylinder with a full cylinder barrel in Independent Constant Rate mode mode 1 at a flow rate of 1 ml min would deliver fluid for 550 minutes and then stop because it had reached the end of its piston stroke and was empty Operation of an individual pump cylinder is most useful to provide overburden pressure to a core sample or when the volume to be pumped is less than the stroke volume so that the single piston stroke limitation is irrelevant Because of the large stroke volume of the 6000 Series pump cylinders there are numerous applications where a single pump cylinder operated in an independent mode works well 4 3 12 6 Paired Cylinder Configuration Two pump cylinders can operate together as a pair to provide continuous flow The two pump cylinders take turns being the active and standby pump cylinder For example in a deliver mode the active pump cylinder is delivering fluid and the standby pump cylinder fills with fluid and pre pressurizes to the delivery pressure level of the active pump cylinder When the active pump cylinder has completed its piston stroke there is a switchover The standby pump cylinder becomes the active pump cylinder and the active pump cylinder becomes the standby pump cylinder In a paired configuration two pump cylinders can pump fluid continuously for an indefin

23. Pressure Transducer A pressure transducer is a device that converts a pressure to an electrical signal proportional to that pressure In the 6000 Series Pump Controller the signal generated by the pressure transducer is sent directly to an A D analog to digital converter which converts the analog electrical signal of the amplifier to a 20 bit digital signal that is displayed on the computer Each individual pressure transducer will have slight variations in zero pressure output voltage zero offset and its output voltage at full pressure gain In the 6000 Series Pump System these variations are compensated for in the controller software The process of adjusting the offset and gain compensation values is called calibration 11 6 2 Methods of Calibrating the Pump System There are two basic methods of pressure calibration for all Quizix Pump Systems The first method is to attach a secondary calibrated gauge such as a quartz transducer to the system With this method the pressure for the calibration procedure will be generated by the Quizix pump Then the pressure read by the Quizix system is adjusted until the system s transducer readings match the reading by the calibrated gauge CG The second method is to use an external pressure source such as a dead weight tester With this method the user connects the external calibrated pressure source PS to the pump system The pressure is then read by the pump system and adjusted unti
