How to replace the liquid parts of the automatic liquid dispenser

The liquid path of an automatic liquid dispenser contains critical components such as pipes, spouts, and seals. Regular replacement of these parts is critical to ensuring the accuracy and performance of the instrument.
Manufacturer recommendations and maintenance schedule:
Before performing parts replacement, first carefully read the user manual and maintenance guide provided by the manufacturer. These documents typically contain recommended intervals, procedures, and precautions for component replacement. It is recommended to develop a regular maintenance schedule to ensure timely replacement when required.
Operator training:
Ensure that operators performing component replacements are adequately trained. This includes understanding the internal structure of an automatic liquid dispenser, becoming familiar with the location and function of parts, and mastering proper replacement procedures. Training helps reduce human error and ensures the accuracy of the replacement process.
Make sure equipment is down:
Before performing part replacement, ensure that the automatic liquid dispenser is in a safe shutdown state. Disconnect the power supply, close relevant valves, and ensure that the liquid system is in a safe condition. This helps prevent accidental leaks or other safety issues.
Clean work area:
Before performing part replacement, clean the work area to prevent any contaminants from entering the system. Use appropriate cleaning agents to clean surrounding surfaces and ensure the operating environment meets clean operating standards.
Correct selection of parts:
Before replacing parts, make sure the parts selected are compatible with the automatic liquid dispenser model and liquid type. Using original parts from the manufacturer is your best option to ensure performance and quality.
Follow the correct replacement steps:
Strictly follow the replacement steps provided by the manufacturer. This may involve steps such as removing old parts, cleaning the area, and installing new parts. Make sure to follow the steps in the correct order to avoid potential problems.
Calibration and verification:
It is very important to calibrate the liquid distributor after replacing parts. Perform calibration procedures to ensure accuracy of new parts according to manufacturer's recommendations. Perform verification testing to ensure that replacement parts will not affect the performance of the instrument.
Records and Document Management:
All steps to replace parts should be well documented. This includes information such as replacement date, part model used, replacement procedures, calibration results, etc. These records help trace the history of the instrument and are part of the quality management system.
Preventive maintenance:
Consider implementing preventive maintenance measures, such as regularly checking the status of components in the fluid path, so that possible problems can be detected in advance and repaired or replaced promptly.
