The way to choose a magnetic flap level gauge cleaner involves a lot of problems to be considered and solved before spending money. Today’s magnetic flap level gauge cleaning machines can perform a variety of cleaning tasks from small desktop or desktop devices with simple switches to advanced cleaning machines with adjustable or controllable working parameters. The capacity of the cleaning solution ranges from less than 1 gallon for household or hobbyist applications to hundreds of gallons for cleaning cars, ships, and aircraft engines.
There are also many different formulas for the chemical composition of the cleaning solution, which should be carefully selected (and maintained) to provide the best cleaning performance according to the nature of the substance to be cleaned and the pollutant removed. Most of today’s popular ultrasonic cleaning solution formulations are in the form of water-based concentrates and are biodegradable. These two functions provide economy, simplify storage and reduce (if not eliminate) disposal problems. The problems and challenges associated with trichloroethylene and perchloroethylene cleaning solvents used in the past no longer apply.The working principle of the magnetic flap level gauge cleanerYou may have heard or know how energy efficient the magnetic flap level gauge is when cleaning products. This is a brief introduction to the working principle of the magnetic flap level gauge cleaner.The magnetic flap level gauge cleaning machine includes a cleaning liquid tank, an ultrasonic transducer is connected to the cleaning liquid tank, and the ultrasonic transducer is driven by the ultrasonic generator of the unit.The transducers are usually glued under the bottom of the tank, although some cleaners glue them to the sides. There are also sensors that are immersed in the water tank-sometimes called shoebox sensors. No matter where they are placed, their functions are the same.Although there are some models that can operate at dual frequencies, most magnetic flap level gauge cleaners are designed to operate at a specific magnetic flap level gauge frequency (see below). When the activated transducer vibrates at its designated frequency, it will cause the bottom of the tank to vibrate in the form of a membrane and generate billions of tiny vacuum bubbles pulsating in the solution. When the bubbles explode, they will release a powerful jet of liquid (cleaning solution), which will be blown away by the contaminants in the cleaning product. This process is called ultrasonic cavitation.When we say strong, we mean it. The temperature range of the shock wave is 5,000 to 10,000?C, which may be about 15,000 to 150,000 psi. However, the process is so fast that when the correct frequency is used, the cleaning of the magnetic flap level gauge is safe. In other words, do not touch the bath of the magnetic flap level gauge that is running.As mentioned above, the range of magnetic flap level gauge cleaner is very wide, from simple device with switch to equipped with timer, temperature control, adjustable magnetic flap level gauge power, optional magnetic flap level gauge A device that counts the frequency and slightly agitates the cleaning basket to improve the cleaning effect.What frequency of magnetic flap level gauge should I use?Manufacturers of magnetic flap level gauge cleaners (such as Tovatech’s Elma) specify operating frequencies in kilohertz (kHz) or thousands of cycles per second. The operating frequency of popular cleaners is 37 or 45 kHz. Other units operate at frequencies such as 25, 80, or 130 kHz.Frequency selection can be important, depending on what is being cleaned. Low frequencies (such as 25 kHz) will produce (relatively) larger cavitation bubbles, which will burst out with greater violence than the high frequencies of 80 and 130 kHz. Low-frequency cavitation is ideal for heavily contaminated parts (for example, metal parts and cast parts). Delicate and highly polished surfaces should be cleaned at a higher frequency (for example, 80 or 130 kHz). It is also recommended to use a higher frequency when cleaning parts with complex shapes and parts with cracks, gaps, blind holes and machined holes. This is because smaller bubbles can better penetrate these hard-to-reach areas.Most cleaning operations can be performed on 37 or 45 kHz equipment. If you clean a variety of products with different characteristics, the dual-frequency magnetic flap level gauge cleaner is a good choice.What size cleaner should I use?First, placing the parts in the basket will perform most of the cleaning operations of the magnetic flap level gauge. This is because the parts to be cleaned should not be in contact with the bottom or sides of the fuel tank. Otherwise, the sound and vibration of the parts will quickly damage the water tank. The only exception is if the parts are suspended in the cleaning fluid, or if the storage tank is made with a chassis, such as some large industrial cleaning machines.Back to our first point: the size of the basket is smaller than the tank size in terms of length, width and depth. You will need to specify the size of the magnetic flap level gauge cleaner tank according to the corresponding basket size to accommodate the parts to be cleaned.In addition, the parts to be cleaned must be completely immersed in the cleaning fluid. Therefore, you must consider the working depth of the so-called cleaning solution. This is defined as the distance from the inner bottom surface of the basket to the surface of the liquid in the filled tank. If the working depth of the device you are considering is not provided or the specifications are not clear, please ask the manufacturer.In particular, if you want to clean small parts (such as machined screws), you can buy a fine mesh basket that can be placed in a standard mesh basket. Alternatively, you can put the parts in a glass beaker filled with cleaning fluid, and then place the beaker in the basket. In this case, the magnetic flap level gauge will penetrate the glass, causing air pockets to act on small parts.Magnetic flap level gauge cleaner bell and whistleAs we mentioned earlier, the range of magnetic flap level gauge cleaners ranges from cleaners with switch buttons to complex equipment that allows users to perform a variety of cleaning tasks. Here are some examples of functions that may be useful.DEG acts as a fresh cleaning solution to quickly shut off the residual air from cavitation suppression on the drive. This can also be achieved by running the cleaner under no load, but in a large-capacity cleaner, this can take a lot of time.The trumpet is a slight change in the ultrasonic frequency to provide a more uniform cleaning throughout the solution.Pulse is activated to provide very high intermittent peaks of magnetic flap level gauge power to remove stubborn contaminants. Pulses can also be used to degas the solution.The heater helps improve the cleaning efficiency of parts contaminated by coolant and other oily contaminants. The heater can be thermostatically adjusted to a maximum of 80?C. Above this temperature, cavitation can be suppressed and the cleaning efficiency can be stabilized. Heat is also a natural by-product of cavitation. (In some cases, an optional cooling coil may be required to help keep the solution temperature within the recommended range.)Adjustable power can provide faster and more effective cleaning results, but more power is not always better. Too much can damage soft metal surfaces, such as polished surfaces of soft metals such as aluminum and other fragile items. The magnetic flap level gauge cleaner with adjustable power is very useful when cleaning various surfaces (including very sensitive items).The stirring of parts in the cleaning process of the magnetic flap level gauge can improve the cleaning speed and efficiency. For example, the vertical vibration of the cleaning basket of 2 cm can increase the cleaning speed by 10 to 20% and improve the cleaning uniformity.How to choose a cleaning solution for magnetic flap level gaugeThe chemical action of the cleaning solution is as important as the frequency and power of the magnetic flap level gauge mentioned in this article. The most commonly used chemical reagents are divided into three categories: alkaline, acidic and neutral. They are usually provided in the form of concentrates, so they are slightly helpful. When formulated with non-toxic biodegradable ingredients, disposal problems can be eliminated. The manufacturer provides recommendations for dilution and cleaning temperature.Because most solutions are based on water, they may rust. You can add rust inhibitor to solve this problem.How many solutions should I use?Good question, this is an important question.Most magnetic flap level gauge cleaners have fill lines or other names that indicate the maximum solution level. You will get the best results when cleaning with a full bucket. But equally important is the so-called service volume. This is the amount of solution required to be completely immersed in water to accommodate the displacement of the part being cleaned. In other words, when you put the parts basket into the tank, the solution should rise to the fill line. Service volume specifications are provided in the user manual.Know this: Filling the tank with water will not increase efficiency. Insufficient filling will aggravate cleaning and may damage the container. This is why the service volume assignment is important. When the basket is empty, it can safely mix the solution, degas and heat it.The following is the recommended process to adapt to different displacements when cleaning different products: Prepare fresh solution for a full tank. Pour the water in half, add the correct amount of cleaning solution concentrate to the entire tank, then fill the tank and activate the ultrasonic and degas mode to mix and degas the solution. You can extract and store the excess amount to accommodate the displacement.How to extend the service life of cleaning fluidAfter maintaining the solution, the cleaning effect will be improved. Degrease and set aside oily contaminants floating on the surface. If you use a larger water tank, please choose a water tank equipped with spray rods and weirs to deal with. Large storage tanks can use filtration systems to capture pollutants. If these pollutants settle and stay at the bottom, the storage tank will be damaged.However, ultimately all solutions must be replaced by emptying the water tank and complying with local disposal regulations. Follow the instructions in the user manual to clean the water tank.Post-cleaning stepsBefore subsequent steps, product rinsing and drying may be required to remove solution residues. This can be done using a washing spray station, washing tank and hot air dryer. Please contact the supplier for equipment options.Other operation tipsAlthough you cannot hear the frequency of the magnetic flap level gauge, the magnetic flap level gauge cleaner (especially the magnetic flap level gauge cleaner operating at a lower frequency) will produce noise due to the vibration of the tank wall. Cover the water tank to reduce noise and reduce evaporation of the solution. It is also recommended to place the water tank in a sound-absorbing shell and use sound-absorbing earmuffs. Some devices may be equipped with heat-insulating covers to reduce noise.Clean with volatile solventWhen cleaning water-sensitive or residue-free products, flammable solvents such as acetone, IPA, MEK and toluene are often used.When using flammable solvents, special equipment is required. In order to solve this problem, an explosion-proof magnetic flap level gauge cleaner should be used. These cleaners, available from Tovatech, carry explosion-proof labels and comply with OSHA standards as well as NEC and NFPA guidelines.They have a high explosion-proof rating because their structure completely isolates potential spark-generating system electronics from solvent vapors or spilled solvents. Their tank capacity ranges from under one gallon to 90 gallons, but they are not equipped with heaters.Important safety pointsExplosion-proof ultrasonic cleaners in operation can create hazardous areas due to cleaning solvent fumes. Smoke must be ventilated using an approved ventilation system. All electrical equipment, wires, lighting equipment, sockets and similar devices must be rated as intrinsically safe in accordance with the provisions of Article 500-503 of the National Electrical Code of NFPA-70.Second, because the solvent evaporates quickly, the operator must keep the solvent level greater than half of the tank’s capacity, otherwise there is a risk of damaging the ultrasonic transducer.in conclusionThis article covers many considerations when choosing an ultrasonic cleaning system. Once the equipment is in place, you will gain experience about preparing the correct amount of cleaning solution for the job done, the best cleaning solution temperature and cleaning time. After the routine program is established, the magnetic flap level gauge cleaner can be programmed according to the functions provided by the equipment through time, temperature, frequency and other variables.
