{Scope of Application}: Widely used in various industrial productions (plastic industry, electronics industry, electroplating industry, food industry, pharmaceutical industry, printing industry, automotive industry, aerospace industry, etc.).

1. UV curing machine:

Features: Stepless dimming+water cooling+metal halide lamp=energy-saving+low temperature+high efficiency. The lamp chamber adopts water-cooled+air-cooled heat dissipation. Insulated quartz glass is installed below the lamp tube to effectively reduce the surface temperature of the illuminated object, protect dry items from thermal deformation, and extend the service life of the lamp tube; The CJW water-cooled series is suitable for domestic and foreign printing equipment such as offset printing machines, gravure printing machines, flexographic printing machines, and gloss coating machines. Offset printing machines such as German Manroland, Heidelberg, Gaobao, Japanese Komori, Ryomei, Mitsubishi, Sakurai, Hokuto, etc. Gravure printing machines such as Swiss Bobst, Italian Serudi, Xi'an Black Bull, Zhongshan Songde

2. Ultrasonic cleaning machine:

Through research, it has been proven that when ultrasound is applied to a liquid, the rupture of each bubble in the liquid generates an energy shock wave, equivalent to instantly producing high temperatures of tens of degrees and pressures of thousands of atmospheres. This phenomenon is called "cavitation", and ultrasonic cleaning uses the shock wave generated by the rupture of bubbles in the liquid to clean and flush the inner and outer surfaces of the workpiece.

The second ultrasonic wave propagates in the liquid, causing the liquid and the cleaning tank to vibrate together at the ultrasonic frequency. The liquid and the cleaning tank vibrate at their own natural frequency, which is the frequency of sound waves, so people hear buzzing sounds.

The suitable cleaning temperature for water cleaning solution is 40-60 ℃, especially in cold weather when the temperature of the cleaning solution is low and the cavitation effect is poor, the cleaning effect is also poor. Therefore, some cleaning machines wrap heating wires around the outside of the cleaning cylinder for temperature control. When the temperature rises, cavitation is prone to occur, so the cleaning effect is better. As the temperature continues to rise, the gas pressure inside the bubble increases, causing a decrease in the impact sound pressure, reflecting the synergistic effect of these two factors.

Based on the final economic factors, Chuanben brand industrial can reduce the temperature of cleaning agents, condense gaseous cleaning agents, and effectively prevent the volatilization of cleaning agents

3. Plastic industry

Injection molding, extrusion molding, blow molding, compression molding, blown film and rolled film, standard industrial models can all be applied to the above industries.

A， Injection mold cooling

The plastic pellets are melted by heating and injected into the mold. After solidification, the mold is opened and the molded plastic workpiece is ejected. In the continuous production process, it is necessary to cool the mold to shorten the plastic solidification time, improve the dimensional accuracy, molding quality, and surface quality of the workpiece.

Temperature requirement for frozen water: 6-18 ℃

Temperature difference requirement for frozen water: ± 2K or ± 0.5K

The cooling capacity of the group is related to the injection volume of the injection molding machine (usually referred to as "Anshi"), and the larger the injection volume, the greater the required cooling capacity.

Injection molding machines are usually labeled with locking force, which requires converting tonnage to Anshi. However, tonnage and Anshi do not correspond one-to-one, and the following comparison table is only a general conversion relationship with some upper and lower deviations.

For special applications in laser systems, they can be specifically designed for industrial use to meet different requirements. Laser freezers are mainly used in laser marking machines, laser engraving machines, laser welding machines, laser coding machines, laser cutting machines and other laser processing equipment.

The intermediate frequency vacuum coating machine generally needs to be equipped with a cooling device as the coating machine (mainly cylindrical target)
Intermediate frequency equipment must be cooled with water because of its high frequency and high current. When current flows through a conductor, there is a skin effect,
Electric charges will accumulate on the surface area of the conductor, causing it to generate heat. Therefore, a mesoporous tube is used to cool the conductor by adding water in the middle.

{Maintenance and upkeep}

1. Cleaning water tower

When using a water-cooled system, it is important to pay attention to the cleanliness of the cooling water source. When the cooling water is dirty or has too many impurities, impurities will adhere to the inner wall of the copper tube when the cooling water flows through the condenser. Over time, a lot of scale will be formed on the inner wall of the copper tube, which significantly reduces the heat exchange between the cooling water and the refrigerant. This reduces the heat carried away by the cooling water from the refrigerant, resulting in poor heat dissipation and affecting the refrigeration effect.

Therefore, it is necessary to regularly clean the cooling water tower, generally at least once a week (depending on the environment). When high-pressure faults occur during the cleaning of the cooling water tower, it is necessary to consider cleaning the condenser to ensure the cooling effect.

2. Compressor

After the compressor has been running for 1000 hours, it should be checked:

Is the compressor refrigeration oil normal

Is the current normal during compressor operation

Is there any abnormal sound when the compressor is running

3. Other

After using the machine for a certain period of time, due to various factors, it is necessary to do the following:

Conduct a performance test on the pressure switch to determine if it can trigger high and low pressure alarms. For the electrical control box, it is necessary to regularly blow out the dust inside and check whether the screws are loose to avoid machine damage and prevent accidents from occurring.

If there are any abnormalities mentioned above, please notify the branch office to dispatch maintenance personnel for handling as soon as possible.
