Magnetic pump filling machines are widely used in the pharmaceutical, chemical, food and other industries due to their high precision and strong corrosion resistance. They are especially suitable for filling liquid products such as flavors, reagents, chemicals, etc. However, during use, in order to ensure the stable operation of the equipment and the filling quality of the product, special attention should be paid to the following points:

1. Preparation before operation
1. Equipment inspection
- Ensure that the appearance of the equipment is intact, the power cord is not damaged, and the connection is not loose.
- Check whether there are foreign objects in the magnetic pump and ensure that the pump body is clean and unblocked.
2. Liquid compatibility check
- Ensure that the liquid to be filled is compatible with the material of the magnetic pump to avoid corrosion of the pump body by the liquid.
- If the liquid is volatile or flammable, confirm whether the equipment is suitable for the safety requirements of the specific liquid.
3. Calibrate equipment parameters
- Adjust the filling speed and time according to the viscosity and filling volume of the liquid to avoid overfilling or underfilling.
- Use water or other test liquids for trial operation to ensure that the filling accuracy meets the requirements.

II. Precautions during filling
1. Monitor the operating status
- Always pay attention to whether the sound of the equipment is normal. If there is abnormal vibration or noise, stop the machine immediately for inspection.
- Ensure that the suction pipe and discharge pipe of the liquid are tightly connected and there is no air leakage.
2. Prevent liquid reflux
- For liquids that are easy to reflux, the check valve should be adjusted or the pipeline design should be optimized to ensure accurate filling.
3. Operator safety
- Operators should wear necessary protective equipment, such as gloves, goggles, etc., especially when handling corrosive liquids.
- It is forbidden to adjust the pump head or replace accessories while the equipment is running to avoid danger.

III. Equipment cleaning and maintenance
1. Regular cleaning
- After each filling, the pipeline and pump body must be flushed with clean water or designated cleaning fluid to avoid crystallization or solidification of residual liquid.
- For filling tasks of multiple liquids, the equipment should be thoroughly cleaned before switching liquids to prevent cross contamination.
2. Check key components
- Regularly check the wear of the pump head and seals, and replace aging parts in time.
- Ensure that the coupling and motor of the magnetic pump are aligned to avoid equipment damage caused by poor alignment.
3. Lubrication and maintenance
- Although the magnetic pump itself has no mechanical contact parts, other moving parts such as conveyor belts and bearings still need to be lubricated regularly.
- When not in use for a long time, the pump body should be cleaned and dried, and the equipment should be stored in a dry and ventilated environment.

Fourth, common problems and solutions
1. The pump does not discharge liquid
- Reason: The liquid inlet pipe is blocked or the suction head is too high.
- Solution: Check whether the pipeline is unobstructed, reduce the suction head, and ensure that the pump is filled with liquid.
2. Inaccurate filling
- Reason: Improper flow parameter setting or change in liquid viscosity.
- Solution: Recalibrate the filling parameters and adjust the operating speed according to the liquid viscosity.
3. The pump body is hot
- Reason: The pump idles for too long or the liquid flow is too small.
- Solution: Avoid pump idling and check whether there is any poor liquid circulation.

V. Scope of application of magnetic pump filling machine
Magnetic pump filling machine is suitable for low-viscosity, particle-free liquids and is widely used in the following fields:
- Chemical industry: solvents, reagents, acid and alkali liquids, etc.
- Food industry: soy sauce, vinegar, wine, flavors, etc.
- Pharmaceutical industry: disinfectants, liquid medicine, injection, etc.

Summary
Magnetic pump filling machine is simple to operate and easy to maintain, but it is necessary to strictly follow the operating specifications during use, especially when dealing with corrosive or volatile liquids, special attention should be paid to the compatibility and safety of the equipment and liquids. Choosing a high-quality magnetic pump filling machine, such as the equipment from CX PACKING MACHINE, can provide users with more reliable performance and longer service life.
