After each use, the residual liquid on the surface of the filling machine should be promptly cleaned to prevent crystallization or corrosion. Pay special attention to the liquid residues on the filling heads and conveyor belts. These can be wiped with a damp cloth, and avoid using sharp tools to scratch the equipment surface.
Check whether all connection components such as pipe joints and screws are loose to ensure the overall structural stability of the equipment. At the same time, observe the operation of the conveyor belt. If there is any deviation or jamming, adjust it in a timely manner.
According to the requirements of the equipment operation manual, regularly lubricate moving parts such as servo motors and gear pumps, and add appropriate lubricating oil or grease to reduce wear and extend the service life.
Parts of the magnetic gear pump such as gears and seals are wearing parts. Regularly inspect and replace them according to the equipment's usage frequency and operating conditions. Generally, the seals should be inspected every 3 - 6 months. If there is any aging or damage, they should be replaced in a timely manner. The gears should be replaced when significant wear or a decrease in accuracy occurs.
Regularly calibrate the filling volume of the filling machine. Tools such as standard measuring cups can be used for measurement to ensure that the filling accuracy is always within the specified range. If the deviation of the filling volume exceeds the allowable value, adjust the parameters of the servo motor or check the working condition of the magnetic gear pump in a timely manner.
In addition to the common filling of large - volume sodium chloride injection solutions, it can also be used for filling small - volume sodium chloride injectables, such as filling ampoules or vials in specifications of 2ml, 5ml, 10ml, etc., to meet different clinical needs.
After appropriate adjustment and cleaning, it can also be used for filling some pharmaceutical solutions with similar properties to sodium chloride, such as glucose and sodium chloride injection, compound sodium chloride injection, etc.
In the food processing industry, it can be used for filling liquid seasonings containing sodium chloride components such as soy sauce and brine, providing the necessary saltiness and anti - corrosion effect for food.
It can be used for filling sodium chloride solutions in some chemical raw materials, such as electroplating solutions and electrolytes. The sodium chloride content and filling accuracy of these solutions also need to be strictly controlled.
In pharmaceutical production, sodium chloride filling machines must meet the requirements of the Good Manufacturing Practice (GMP) for pharmaceutical products. This includes all aspects of equipment design, manufacturing, installation, operation, and maintenance, ensuring that no adverse effects are exerted on the quality of pharmaceutical products, and guaranteeing the safety, effectiveness, and quality controllability of drugs.
The quality of the sodium chloride injection filled by the filling machine must comply with the relevant standards of pharmacopoeias of various countries, such as the Chinese Pharmacopoeia and the United States Pharmacopoeia. This requires that during the filling process, the filling machine should ensure the accurate dosage, sterility, and pyrogen - free nature of the injection.
Sodium chloride filling machines used in the food industry need to comply with food - related hygiene standards and safety regulations, such as the "National Food Safety Standard - General Safety Requirements for Food Contact Materials and Articles", etc., to ensure that the equipment components in contact with food do not release harmful substances and do not contaminate food.
Sodium chloride filling machines used in the chemical industry should follow the relevant specifications and standards of the chemical industry, such as the safety design standards for chemical equipment and the operation specifications for chemical liquid filling, to ensure the safety and stability during the chemical production process.
