The use of many areas can all see it. However, ultrasonic cleaning machine ultrasonic spray nozzle without proper care, so its service life will shorten, so in a timely manner to maintain is indispensable. All the commonly used method for the maintenance of ultrasonic cleaning machine, if the user is in strict accordance with the above points to the operation, then can effectively extend the lifespan of the ultrasonic cleaning machine, also can reduce the maintenance cost to a great extent. So some maintenance skills for each user's interest. 1, first of all should take credible ultrasonic cleaning machine in ventilated place, every time and drainage water injection and maintenance of ultrasonic cleaning machine should be shut off the power, also need to plug in a timely manner after use.
2, completes the occupational protection. Daily operation to complete the ultrasonic cleaning machine, need to use twist dry clean soft cloth to wipe the instrument surface and inner cavity, and resistance to acid and alkali gloves should be worn when derusting descaling. Must pay attention to avoid to use steel wire ball or hard brush to wipe, lest cause damage to the ultrasonic cleaning machine.
3, regular scale and rust removal of ultrasonic cleaning machine ultrasonic handheld welder lumen, descaling agent or herbicides mixture ratio should be in strict accordance with the instructions, and in accordance with the related processes, derusting descaling: shut off the power and the inner cavity drainage to try to close the drain valve, with corresponding proportion scale remover or rust remover solution and rinse clean with clear water will be cleaner or rust remover and water after dry wipe with clean cloth. 4, check the valve of ultrasonic cleaning machine work is normal, check the method reference to the manufacturer instructions, if found abnormal ultrasonic cleaning machine, you need to report or hire a professional personnel for repair in time. In addition also need every year for calibration instrument, such as temperature sensor (done by professional maintenance personnel).
Use inspection and transducer connected by megger plug, check the transducer Ultrasonic nano dispersion of the positive and negative electrode insulation resistance value can be judged. General requirements above insulation resistance greater than 30 ohms. If can not reach the insulation resistance, is likely to be transducer be affected with damp be affected with damp. Repair method is to put the transducer as a whole (not including housing) into the oven set about 100 ℃, drying three hours or use hair dryer to tide until normal value. Light transducer vibrator, ceramic material fracture. Maintenance can be combined with the naked eye and megohmmeter. Generally as an emergency treatment measures, can the individual transducer cut off of the damage will not affect the normal use other transducer.
Transducer is the most basic factor for its produce the strength of the cavitation effect. Ultrasound and other sound, is a series of pressure point, namely a kind of compression and expansion wave alternately. If the sound energy is strong enough, the expansion of the liquid in the wave phase is away, the resulting bubble; In the wave of the compression stage, the bubbles in the liquid instantaneous burst or implode, produce a kind of very effective impact, especially suitable for the cleaning.
Burst of cavitation bubble will produce more than 10000 psi pressure and the high temperature of 20000 ° F (11000 ° C), and the ultrasonic cleaning machine burst in shenzhen instantaneous blast will rapid outward radiation. Energy released by a single cavitation bubble is very small, but every second for millions of cavitation bubble burst at the same time, the cumulative effect will be very strong, produce the powerful impact of contamination of the workpiece surface spalling, this is all the characteristics of the principle of ultrasonic cleaning machine.
