Principle of vacuum decompression system of ultrasonic cleaning machine

        Powerful ultrasonic cleaning machine vacuum decompression system, equipped with vacuum decompression pump and vacuum display table. Equipped with a vacuum motor and a solenoid valve, the recovery rate of vacuum distillation is 200l/h, and the boiling point of carbohydrates is 172°C under normal temperature and pressure. Under reduced pressure, the boiling point can drop. Under the condition of reduced pressure, the high-temperature carbohydrates quickly form hc vapor, which is extracted from the recovery tank of the ultrasonic cleaner together with the vacuum pump to form a liquid in the cooling box. After the activated carbon is filtered, it is called regeneration liquid and can be recycled.

1. Characteristics and precautions of hydrocarbon

1. Common sense supplement

        We have already said that the cleaning effect and cleanliness of the ultrasonic cleaner with the carbon dioxide will be better, and the hydrocarbon-containing cleaners have four structures of positive, susceptible, cyclic and aromatic hydrocarbons, and they have the following characteristics:

        The cleaning ability of metal working oil is strong → due to the small surface tension, the cleaning effect of fine slits and pores is good. It has good solubility for liquid crystal dust, especially biphenyl dust. In recent years, a variety of cleaning agents have been developed to clean various contaminants (water-soluble processing oils, registration agents, peeling agents). It does not corrode metals, but has little effect on resins. Most hydrocarbon cleaners can be recycled after passing through the distillation system of an ultrasonic cleaner, which is very economical

2. Precautions: The weakness of hydrocarbon compounds lies in their low ignition point, so attention must be paid to the explosion-proof of cleaning equipment and surrounding places.

2. Summary

        Since the introduction of hydrocarbon cleaners and ultrasonic cleaners on the market, they have been widely used as replacements for ozone-depleting substances or chlorinated solvents in automobiles, electronic equipment, automobiles, fine parts, heat treatment and other industries in my country and other Asian countries. Taste. Although hydrocarbon systems are inferior to chlorine systems in terms of flammability and dryness, this can be fully compensated for by improved cleaning equipment . It has small evaporation loss, less usage, low operating cost, no adverse impact on the environment, and the cleaning function is fully guaranteed. Therefore, the hydrocarbon system of ultrasonic cleaners has gradually become the mainstream of cleaning agents. In addition, from the perspective of ISO14000 series environmental management, hydrocarbon decontamination solvents have gradually become star products.
