The operation method of diagnostic reagent filling machine can be divided into equipment preparation, operation, parameter setting, and maintenance. The specific process is as follows:
1、 Equipment preparation and inspection
1. Placement and installation: Place the filling machine on a flat and stable workbench to ensure a safe distance between the equipment and surrounding facilities.
2. Power and gas source connection: Connect to a 380V power supply and ground it, with a stable air pressure of 0.05~0.07MPa.
3. Component inspection: Confirm that there are no abnormalities in key components such as the filling head, conveyor belt, and control system, and add new lubricating oil to lubrication points.
2、 Running operation process
1. Startup:
Turn on the main power and touch screen, and check parameters such as air pressure and hydraulic oil level.
Start the conveyor belt and neatly place the reagent tubes into the bottle hopper, ensuring no tipping over.
2. Filling and sealing:
By using a peristaltic pump for quantitative filling, the accuracy can reach ± 1%.
The capping station adopts servo motor control, with adjustable torque and no damage to the capping.
The sealing process uses hot pressing technology to ensure no dripping or leakage.
3、 Parameter setting and monitoring
1. Filling volume adjustment: Set the target capacity through the touch screen and support dual mode calibration of coarse adjustment and fine adjustment.
2. Speed control: Adjust the filling speed according to the viscosity of the material, and replace the position of the pulley if necessary.
3. Safety monitoring: Real time monitoring of parameters such as air pressure and liquid level, triggering alarms in case of abnormalities.
4、 Maintenance and troubleshooting
1. Daily cleaning: Use non-woven fabric to clean parts that come into contact with reagents, in compliance with GMP cleanliness requirements.
2. Common faults:
Inaccurate filling volume: Check the sealing ring, throttle valve or clean the blockage.
Pneumatic abnormality: Check for cylinder O-ring wear or air path leakage.
Shutdown maintenance: Cut off the power and gas supply, and regularly replace vulnerable parts such as sealing rings.
5、 Precautions
1. It is strictly prohibited to put hands into the area of moving parts during operation.
2. Thoroughly clean during production changes to avoid cross contamination.
