Extending the lifespan of automatic liquid separators: a comprehensive guide from daily maintenance to troubleshooting

In laboratory, medical testing and other scenarios, automatic liquid separators have become the core equipment with their precise and efficient liquid separation capabilities. But many users have found that the equipment may experience problems such as inaccurate liquid separation and leakage after prolonged use, which are mostly related to neglecting maintenance. Mastering scientific maintenance methods and common troubleshooting techniques can not only extend the service life of automatic liquid separators, but also ensure the reliability of test results and reduce usage costs.

　　Daily maintenance: the core foundation for extending lifespan

1. Cleaning and maintenance should be done in a timely manner

After each use, it is necessary to clean the surface of the equipment and parts that come into contact with liquids in a timely manner. For critical parts such as nozzles and pipelines, distilled water can be used to rinse and remove residual samples; If it comes into contact with corrosive or viscous samples, it is necessary to soak them in a special cleaning agent and rinse them to avoid chemical corrosion of components or sample drying and blockage of pipelines. When cleaning, be careful to avoid directly flushing electrical components such as control panels and motors with water to prevent short circuit damage. Deep cleaning can be carried out once a week, removing vulnerable parts such as suction needles and sealing rings, carefully wiping away stains, and reinstalling.

2. Regular calibration is essential

Accuracy is the core advantage of automatic liquid separators, and calibration is the key to maintaining accuracy. It is recommended to calibrate every 3-6 months using standard weights or calibration solution, and adjust the separation accuracy according to the steps in the equipment manual. If the equipment is frequently used for high demand experiments or after transportation, it needs to be calibrated in a timely manner. Calibration records should be properly retained for easy traceability and maintenance in the future.

3. Replacement of vulnerable parts should be timely

Sealing rings, suction needles, pipelines, and other vulnerable components can experience aging, wear, and cracking over long-term use. Regularly inspect these components. If the elasticity of the sealing ring decreases, the suction needle deforms, or the pipeline is damaged, the original accessories should be replaced in a timely manner. Do not use non original accessories, otherwise it may cause leakage, inaccurate separation, and even damage to the equipment body due to size mismatch. It is recommended to reserve commonly used vulnerable parts in advance to avoid affecting work progress in the event of a malfunction.

4. The storage environment should be suitable

When storing equipment, it is necessary to choose a dry, ventilated, and non corrosive gas environment, with a temperature controlled at 15-25 ℃ and a relative humidity maintained at 40% -60%. Avoid placing the device in direct sunlight, severe vibration, or areas with a lot of dust. When not in use for a long time, disconnect the power supply, drain the liquid in the pipeline, cover it with a dust cover, and run it regularly for 5-10 minutes to prevent component aging and adhesion.

　　Common troubleshooting: Quickly solve usage problems

1. Inaccurate liquid separation volume

This is the most common malfunction, often caused by expired calibration, bubbles or residues in the pipeline, and blockage of the suction needle. When troubleshooting, first check if it has not been calibrated for a long time, and if it has not been calibrated, calibrate it in a timely manner; If there are bubbles in the pipeline, they can be discharged through the exhaust function of the equipment, or the pipeline can be disassembled and the exhaust can be reinstalled; If the suction needle is blocked, a dedicated needle can be used to clear it, and then rinse with cleaning agent. In addition, abnormal viscosity and temperature of the sample can also affect the accuracy of liquid separation, and it is necessary to ensure that the sample meets the requirements for equipment use.

2. Equipment leakage

Leakage often occurs at the joint, sealing ring, or suction needle. Firstly, check if each joint is loose. If it is loose, gently tighten it; If there is no problem with the joint, observe whether the sealing ring is aging or deformed, and replace it in a timely manner; Damaged suction needles can also cause leakage and require replacement with new ones. At the same time, attention should be paid to the pressure setting during liquid separation. Excessive pressure may cause pipeline rupture and leakage, and it is necessary to operate according to the pressure range specified by the equipment.

3. Unable to start normally

When the device cannot be started, first check whether the power connection is normal, whether the plug and socket are in good contact, and whether the power cord is damaged; If the power supply is normal, check if the fuse is blown. If it is blown, replace it with a fuse of the same specification; If it still cannot be started, it may be a control panel or motor malfunction. Do not disassemble it yourself at this time, and contact the manufacturer's professional maintenance personnel for handling.

4. Pipeline blockage

Blockage in pipelines can lead to difficulty in liquid absorption or separation, often caused by residual dry lumps or foreign objects entering the sample. You can first rinse the pipeline with distilled water. If the blockage is severe, remove the pipeline and soak it in a special cleaning agent for 30 minutes before rinsing. If necessary, gently unclog it with a fine needle and be careful not to damage the inner wall of the pipeline.

The service life of an automatic liquid separator is closely related to daily maintenance. Scientific cleaning, regular calibration, and timely replacement of vulnerable parts can reduce the occurrence of failures from the source. When encountering faults, follow the principle of "simple first, complex later" to troubleshoot. Most small problems can be solved by themselves, while complex faults require seeking professional support. Maintain the equipment properly to ensure that the automatic liquid separator always maintains its optimal working condition, providing support for experimental testing work. If you encounter specific problems during maintenance or troubleshooting, you can consult the equipment manufacturer or professional technicians at any time.
