The adjustable high-speed homogenizer (taking YQ-3 as an example) is a core equipment in the fields of biochemistry, food processing, pharmaceuticals, etc. Its stable operation is directly related to experimental and production efficiency. This article systematically elaborates on the maintenance plan of equipment from four dimensions: daily cleaning, maintenance of key components, fault prevention, and operating standards.

1、 Daily cleaning: prevent cross contamination and performance degradation

1. Instant cleaning and deep disinfection

Clean the homogenization cup, blade, and temperature control cup immediately after each use. The specific steps are:

Physical cleaning: Use a soft bristled brush to remove any residue from the blade and avoid scratching with metal tools to prevent surface damage;

Chemical disinfection: For food or pharmaceutical grade applications, soak in 75% ethanol or sodium hypochlorite solution for 30 minutes, and then rinse with deionized water;

Dry storage: After cleaning, dry in a 60 ℃ oven for 2 hours or blow dry with compressed air to prevent microbial growth.

2. Anti corrosion treatment

If handling acidic or alkaline samples (such as solutions with pH<3 or>10), the residue should be neutralized with a 1% sodium bicarbonate solution after cleaning, and then rinsed with pure water to avoid corrosion of metal parts.

2、 Key component maintenance: Ensure stable core performance

1. Maintenance of motor and speed control system

Moisture prevention management: The motor and speed controller should be stored in a dry environment (relative humidity<65%). If they are accidentally damp, they should be dried with 50 ℃ hot air circulation for 4 hours before use;

Carbon brush replacement: Check the wear of the carbon brush every 200 hours of operation. If the length is less than 8mm, it needs to be replaced to avoid excessive sparks damaging the commutator;

Bearing lubrication: Add high-temperature resistant lubricating oil (such as Shell Alvania RL3) every six months, and clean the oil hole before oil injection to prevent impurities from entering.

2. Periodic replacement of blade and bottle cup

Blade sharpness detection: Observe the blade angle with a microscope every month. If the symmetry deviation is greater than 2 ° or there is a notch, it needs to be replaced immediately;

Integrity inspection of bottle cups: Before each batch of use, check whether the sealing ring of the bottle mouth is aging. If cracks or deformations are found, replace the matching bottle cup to prevent leakage during high-speed operation.

3、 Fault prevention: from operating standards to regular inspections

1. Pre operation checklist

Power supply compatibility: Confirm that the voltage (220V ± 10%) and frequency (50Hz) meet the equipment requirements;

Mechanical positioning calibration: Rotate the bottle cup clockwise to the locator, and use a level to check the perpendicularity between the motor shaft and the knife shaft, with a deviation of<0.5 °;

Governor zeroing: Before starting, adjust the knob to zero position to avoid overloading of the components caused by instantaneous high speed.

2. Exception handling during operation

Abnormal noise: If there is a metal friction sound, immediately stop the machine and check if the bearing is stuck or if the blade is loose;

Speed fluctuation: When the speed regulator cannot output stably, check the voltage of the voltage stabilization module (standard value 24V ± 0.5V), and replace the capacitor if necessary;

Overheating protection triggered: If the continuous operation exceeds 30 minutes, pause for 5 minutes to prevent the motor from overheating.

4、 Long term storage management: ensuring device reuse performance

If the equipment needs to be discontinued for a long time, the following measures should be taken:

Dustproof packaging: Wrap the whole machine with anti-static film and store it in an environment with a temperature of 10-30 ℃ and humidity<50%;

Regular start-up: Every 3 months, power on and run for 10 minutes to test the motor and speed control system functions;

Component lubrication: Apply anti rust grease (such as Molykote X-5) to the bearings and transmission components before storage to prevent rusting.

Through a systematic maintenance plan, the YQ-3 adjustable high-speed homogenizer can achieve stable operation for more than 5 years, reduce failure rates by 60%, and ensure consistency in sample processing. Operators need to establish maintenance records to document every cleaning, component replacement, and abnormal situation, providing data support for equipment lifecycle management.
