Application of Kinco Servo in High Precision Quantitative Injection Pump

1, system introduction

Sea Pa pump is a positive plunger pump, the typical structure of one-way valve and rotary valve type pump two. Check valve pumps are used in low and medium viscosity liquids with viscosities ranging from 1 to 10,000 cps. Rotary valves are used in liquids with high or medium solids viscosities ranging from 100 to 50,000 cps.

The unique and compact design of the HABA pump enables a variety of fluid injection functions and excellent performance: Micrometer capacity regulators for extremely high metering accuracy and repeatability; the actual measurement accuracy is higher than the nominal Plus or minus five thousandths, some pump models still achieve very high accuracy with a 1-μL injection volume. Independent speed control components, to achieve a variety of conditions under the liquid injection.

1) The use of sea Pa pump using eViewMD304L and Kinco servo system (stand-alone)

Basic selection of programs Model:

Servo motor: 23S21-0560-803J7

Technical parameters: Working torque 1NMm, rated phase current 5.6A, flange 56mm.

Servo drive: ED100 (using Profibus ED100 communication port on the scene more than one servo drive networking)

Text Display Model: MD304L

Switching power supply: 220V input, 60V and 24V output

Options: PDC Adapter PDC-24 (optional electronic measuring instrument Co., Ltd. Kunshan Yu Heng JBX electronic selection)

Basic process requirements:

As shown below, stop time T1, T2 can be set, injection volume (length), injection speed (motor speed) can be set to automatically remember the number of injections, the total injection volume. Jog, manual single, automatic (the number can be set).

Accuracy: ± 0.2% Stroke motor about three revolutions, the servo motor positioning error requires ± 48 pulses.

The mechanical part also has a direct effect on the accuracy.

Resolution: 0.001 ml Each motor revolution = injection of 0.712557392 ml of product,

Pulse resolution = 0.000089069 ml.

Operation: Requirements Each station length, speed, frequency of the target value can be set, the current value can be displayed, with

Jog function.

Project Design, Implementation (Application Engineer: Lin Jinsen)

1) The use of the sea Pa pump using my company eView text display and Kinco servo system (multi-machine applications) for the overall program implementation, the need to use MT5700T to do the total monitoring data processing, the use of Siemens S7-300 (315CPU), the system control system (Peripheral control + servo system networking PROFIBUS-DP, 12M baud rate).
