Introduction to the principle of ultrasonic cleaning machine

  Ultrasonic wave spreads in the liquid, making the liquid and the cleaning tank vibrate together under the ultrasonic frequency. When the liquid and the cleaning tank vibrate, they have their own natural frequency. This vibration frequency is the sound frequency, so people hear the buzzing sound. With the continuous development of the cleaning industry, more and more industries and enterprises have applied ultrasonic cleaning machines.     For the principle of ultrasonic cleaning machine, the high-frequency oscillation signal sent out by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and transmitted to the medium - cleaning solvent. The forward radiation of ultrasonic waves in the cleaning liquid makes the liquid flow and produces tens of thousands of straight diameters of 50-500 μ M, the tiny bubbles in the liquid vibrate under the action of the sound field. These bubbles form and grow in the negative pressure area of ultrasonic longitudinal propagation, while in the positive pressure area, when the sound pressure reaches a certain value, the bubbles increase rapidly, and then suddenly close. When the bubble closes, it generates a shock wave, which generates thousands of atmospheres around it, destroys the insoluble dirt and disperses them in the cleaning fluid. When the group particles are wrapped by oil and adhere to the surface of the cleaning part, the oil is emulsified and the solid particles are separated, so as to achieve the purpose of cleaning the parts. In this process called "cavitation" effect, bubble closure can form a high temperature of several Baidu and an instantaneous high pressure of more than 1000 air pressures. The advantages of ultrasonic cleaning machine are: good ultrasonic cleaning effect, simple operation. The sound people hear is an acoustic signal with a frequency of 20-20000hz. Sound waves higher than 20000hz are called ultrasonic waves. The transmission of sound waves propagates longitudinally according to the sinusoidal curve, producing a large number of small bubbles. One reason is that there is tensile stress locally in the liquid and a negative pressure is formed. The reduction of pressure makes the gas originally dissolved in the liquid supersaturated, and it escapes from the liquid and becomes a small bubble; Another reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation.

How much temperature is appropriate for ultrasonic cleaning equipment?

The cleaning effect of ultrasonic cleaning equipment is very significant, and the cleaning efficiency is high, so it is deeply favored by everyone. When using ultrasonic cleaning equipment for cleaning   The core component of high-pressure water jet equipment is the high-pressure pump, whose main function is to turn quantitative water into high-pressure water flow, making the water flow have a strong impact. Among them, there are various types of high-pressure pumps, such as high-pressure piston pump, high-pressure reciprocating pump, high-pressure electric pressure test pump and so on. Among them, piston pump is the most common high-pressure pump used in high-pressure ultrasonic cleaning machine. The main reason is that piston pump has high operation efficiency and longer service life. The piston of high-pressure pump is generally made of ceramic, which is not easy to be worn, so it has a long service life.   Piston pump is through a fixed seal, a piston moves back and forth. Piston pump relies on the reciprocating motion of the piston to make the working volume of the pump chamber change periodically, so as to realize the suction and discharge of liquid. The seal of the plunger pump is installed on the plunger and passes through a smooth cylinder wall. It is mainly a pump that uses the plunger to reciprocate in the pump cylinder to change the volume between the plunger and the pump wall, repeatedly inhale and discharge liquid and increase its pressure. Generally, plunger pump has better initial use characteristics. Its advantages are high rated pressure, compact structure, high efficiency and convenient flow regulation. However, its disadvantages are that it can not operate at too high pressure and its service life is short.   The water capacity of the pump depends on the running speed of the pump, and the pump must allow the same amount of water to enter and exit. The water flow parameters of the piston pump are stable, that is, the water flow sprayed out under different pressures of the equipment is unchanged. Therefore, if the nozzle or high-pressure pipe is blocked, the pressure of the high-pressure pump will be too large. Therefore, devices such as pressure relief valves must be installed in the equipment system.   The most likely cause of failure of high-pressure cleaning machine is usually not the pump. Pump failure is generally caused by the wear of components or parts, such as the wear of nozzle seals. Generally speaking, the insufficient water inflow in the pump is one of the main reasons for the failure of the pump in the early use stage. Generally speaking, it is because the diameter of the inlet pipe is too small or the water supply is insufficient, which leads to insufficient water entering the pump, causing cavitation in the pump. Cavitation causes a small explosion of the gas mixed in the water, resulting in overpressure damage and piston surface wear.   The above is a brief description of the pump of the high-pressure washer. The pump is the heart of the operation of the high-pressure washer, so the quality of the pump affects the cleaning effect and service life of the machine.
