Wet laser particle size analyzer, as a precision testing equipment, is widely used for measuring particle size and its distribution. Winner2009 wet laser particle size analyzer has become the * * * in the market due to its high precision, intelligence, and full range testing range. However, in order to ensure its long-term stable operation and maintain high-precision measurement results, daily maintenance and upkeep are crucial.
1、 Daily maintenance
1. Cleaning and dust preventionAfter each experiment, the sample tank and injection pipeline should be cleaned immediately to prevent sample residue from causing blockage or affecting the next measurement result. At the same time, regularly wipe the instrument casing with a soft cloth to keep the instrument clean, and clean accessories such as sample spoons and containers. When not in daily use, a dense dust-proof cloth should be covered to prevent dust from accumulating and entering the interior of the instrument.
2. Laser light source and optical path inspectionRegularly check whether the He Ne laser is working properly and whether the laser power is stable. At the same time, check whether there is any deviation or shading in the optical path to ensure that the laser smoothly passes through the sample cell and reaches the detector. The Winner2009 wet laser particle size analyzer uses a precision four item hybrid stepper motor to form an optical path automatic alignment system, but regular inspections are still required to ensure its micro motion accuracy reaches the micrometer level.
3. System connection and software updatesCheck if the connection between the instrument and the computer is normal, and ensure that data transmission is error free. At the same time, regularly check and update software to use the latest features and fix known issues. When plugging or unplugging cable signal lines, be sure to turn off the power switch first to avoid damaging the instrument or causing abnormal data transmission.
4. Inspection of pump and mixing systemWinner2009 wet laser particle size analyzer uses a high-power circulation pump to optimize the pipeline design. Therefore, it is necessary to regularly check whether the water pump and ultrasonic mixing system are working properly to ensure that the sample can be evenly dispersed. At the same time, check whether the waterway system is unobstructed and whether there is any leakage.
5. Exhaust and DrainageAfter the experiment is completed, the liquid in the sample pool should be emptied and the exhaust and drainage systems should be ensured to be unobstructed. Wet attachments that have not been used for a long time should be wiped clean with a mirror paper dipped in ethanol to avoid water stains.
2、 Precision maintenance
1. Environmental controlMaintain stable temperature and humidity in the environment where the instrument is located. Significant temperature fluctuations may affect the performance of optical and electronic components, while high humidity may lead to mold growth in optical lenses. The Winner2009 wet laser particle size analyzer should be placed in an environment with relatively stable temperature and moderate humidity to avoid extreme temperature and humidity changes. It is recommended to install air conditioning with heating and dehumidification functions in humid or low-temperature areas to maintain a dry environment.
2. Vibration and interference protectionThe instrument should be placed on a stable and sturdy tabletop to prevent vibration, knocking, or other mechanical interference. Surrounding areas should avoid interference sources such as strong magnetic fields and strong electric fields to prevent affecting measurement accuracy. The fully built-in dispersion system and high-precision optical path design of Winner2009 wet laser particle size analyzer are particularly sensitive to vibration and interference, so special attention should be paid to protection.
3. Sample pretreatmentDuring the operation, the sample needs to undergo sufficient pre-treatment to ensure that there are no large particles, so as not to block the injection pipeline. If there are large particles in the sample, a suitable sieve should be used for screening or other pretreatment methods should be used to remove them. Select appropriate dispersion media and dispersants to assist in sample dispersion and ensure the accuracy of measurement results.
4. Regular calibrationRegularly calibrate the instrument using standard substances to ensure the accuracy of measurement results. The high-precision measurement of Winner2009 wet laser particle size analyzer relies on its advanced detection system and fitting technology, but long-term use may still lead to error accumulation, so regular calibration is needed to maintain accuracy.
5. Professional training and operating standardsEnsure that operators have received professional training and are familiar with the operating procedures and maintenance processes of the instrument. Strictly follow the operation manual, use the instrument correctly, and avoid improper operation that may cause damage to the instrument or decrease in accuracy.
3、 Summary
The daily maintenance and accuracy maintenance of wet laser particle size analyzer is a systematic process that requires starting from multiple aspects such as cleaning and dust prevention, laser light source and optical path inspection, system connection and software updates, pump and stirring system inspection, exhaust and drainage. At the same time, attention should also be paid to environmental control, vibration and interference protection, sample pretreatment, regular calibration, as well as professional training and operating standards. By following these steps and precautions, the service life of the instrument can be effectively extended, high-precision measurement results can be maintained, and reliable data support can be provided for scientific research and production.
