     4-3、system setting

                                                           Pic. 7 System setting

              ⑴Rated displacement: the rated displacement of gear pump in current system.

              ⑵Rated speed: current system servo motor rated speed.

         4-4、Quantitative model

                                                                                Pic. 8  Quantitative model

  (2)Speed setting: motor speed in quantitative mode, not higher than rated speed.

        (3)Interval time: delay time between completion of each quantitative filling in automatic mode.

       (4)Quantity setting: the total number of filling required in automatic mode, and the machine will stop automatically after reaching the set value. If it is set to 0, it is the manual mode, Press start once to complete parameter setting only once; At this time, the external switch signal can also control the program.

        (5)Revolution completed: the number of revolution completed currently.

        (6)Completed quantity: the number of completed work in automatic mode or manual mode. In the automatic mode, when the set quantity is reached, stop and press the stop key to clear the quantity.        

       4-5、Displacement mode                                                                                      Pic. 9  Displacement mode

               (1) Speed setting: the speed of motor in Displacement mode.

           (2)Instantaneous flow:In the conveying mode, the theoretical flow is calculated by multiplying the real-time speed of the motor and the displacement of the pump.Due to the structural characteristics of the gear pump, the greater the inlet and outlet pressure difference, the smaller actual flow is  less than the theoretical flow.

           (3)Setting time: the total running time set for the conveying mode. When the time is up, the machine stops working. If set to 0, it will run continuously after startup.At this time, the external switch signal can also control the program

           (4)Working time: the current running time of Displacement  mode

        4-6、  External control mode

(1) In quantitative mode: start using when the quantity is set to 0.。

(2) In conveying mode: start using when the time setting is all 0.

Product Characteristics:

No pulse, high precision.

the external gear design makes the pump flow relatively unaffected by the system pressure,and the flow output has no pulsation, which can accurately measure the flow, and has strong repeatability.

Stable transmission.

Gear transmission can ensure constant instantaneous transmission ratio.

Zero leakage.

no packing seal or mechanical seal, no wearing parts, using magnetic drive, static seal,truly achieve zero leakage.

Corrosion resistance.

304 / 316L, Hastelloy and engineering plastics can be selected as pump body materials,which can be used in most chemical media.

Efficient and convenient, long service life.

adopt the way of motor direct drive, reduce the vulnerable parts. High efficiency and energy saving, simple maintenance, low installation cost, long service life.

Applicability.

suitable for high differential pressure, high system pressure and wide range of medium viscosity.

long service life.

The magnetic drive design of the non dynamic seal makes the shaft end no longer need the dynamic seal, which ensures the leakage free operation of the pump. The solid and stable shaft support can ensure the accurate meshing of the gear when the pump is running at high speed, ensure the smooth operation of the pump, the high accuracy of metering and the long service life of the pump.

Diversified drive mode.

magnetic drive gear metering pump can be directly connected with DC brushless motor,2-pole and 4-pole AC motor without reducer. The flow control of the pump can be realized by the controller of AC, DC, brushless DC and other motors. We can provide a variety of standard driving methods to meet the needs of customers.

A wide range of applications.

magnetic drive gear pump in the design, manufacture and application of a large number of use of magnetic drive, pump and motor technology. It has the advantages of no pulsation, long life and no leakage. These advantages make our products widely used in chemical, medical, laboratory, water treatment, food and other industries.

Applicable conditions:

All kinds of liquids, high precision fluid transportation, high repeatability, continuous small flow without pulsation.

It is used in aviation equipment, aircraft, spacecraft, chemical laboratory, chemical reagent adding, film manufacturing, pharmaceutical machine equipment, various lasers, micro cooling device of sighting instrument,tobacco flavoring adding, inkjet printing machine manufacturing, inkjet printer manufacturing, high-performance color printing machine and other industries.
