Product Introduction

----------------------------------------------------------------------

Application scope of small chillers
1. UV curing machine:
Features: Stepless dimming+water cooling+metal halide lamp=energy-saving+low temperature+high efficiency. The lamp chamber adopts water cooling (Chuanjing small chiller chilled water)+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; Small chillers are suitable for domestic and foreign printing equipment such as offset printers, gravure printers, flexographic printers, and 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 produces a highly energetic shock wave, equivalent to instantly producing high temperatures of several hundred degrees and pressures of up to 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 most 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, the Chuanjing brand industrial small chiller can reduce the temperature of cleaning agents, condense gaseous cleaning agents, and effectively prevent the volatilization of cleaning agents
3. Plastic products industry:
Injection molding, extrusion molding, blow molding, compression molding, blown film, and rolled film
Standard small chillers can be applied to the above-mentioned 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 a small chiller unit 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 as "tons" of clamping force, which requires converting "tons" to "Anshi". However, "tons" and "Anshi" do not correspond one-to-one, and the following comparison table is only a general conversion relationship with some deviation.
B， Extrusion molding
Extruded pipes, cable trays, cables, and various plastic profiles.
After heating and melting the raw materials through the mold, they are cooled in a freezing water bath, and the water temperature in the freezing water bath must be kept constant.
Due to high production speed and the need for large cooling units.
If the existing frozen water tank is large enough, the unit may not be equipped with a water tank.
C, Blow bottle
We mainly produce various types of mineral water bottles and soda bottles.
Compressed air drying - blowing bottles requires clean and dry compressed air, and the use of frozen water provided by industrial small chillers as a cold source can remove moisture from the compressed air.
Mold Cooling - Small scale chiller can accurately control mold temperature, improve product quality, and increase production efficiency
Compressed air drying and mold cooling can use the same small chiller as the cold source
D， thermoform
The most common products are those with fewer containers, such as yogurt cups
It is very important to maintain a constant temperature during the extrusion molding of plastic by a mold heated at a constant frequency, and the temperature difference range of the chilled water is very high. Therefore, a proportional chilled water valve is needed to automatically adjust the temperature.
E, hydraulic system
Mold opening, mold closing, and material injection all require a hydraulic system to complete. The hydraulic oil absorbs energy from the hydraulic pump and the temperature rises. Typically, the oil temperature should not exceed 60 ℃.
A cooling water temperature of approximately 27 ℃ is more suitable. As the required water temperature is different from that of the mold, it is necessary to separate the electric water valve from the mold cooling circuit or to have an independent cooling system.
4. Machinery usage industry:
A, laser technology
The laser source, beam controller, and electrical control cabinet in the laser system may require additional cooling.
The temperature requirement for frozen water is usually between 15... 22 ℃, and the accuracy requirement for frozen water is usually ± 1K or ± 2K. Some devices may require ± 0.5K,
In addition, some equipment has certain requirements for frozen water conductivity, corrosion resistance, etc.
Laser systems usually have certain requirements for water temperature during startup, which requires the addition of electric heating in the water circuit.
In some systems, the beam controller may require an independent cooling circuit.
For special applications in laser systems, industrial small chillers can be specifically designed to meet different requirements.
B, welding
Electrodes, welding furnaces, and cutters all require cooling.
Cooling of electrode nozzles for large and medium-sized welding machines; Electric furnace cooling for gold and silver jewelry processing
Usually small to medium-sized chillers.
Need an internal and external circulating water pump system or a closed water tank system.
C， Cutting Processing
Many cutting machines (such as machining centers, lathes, milling machines, drilling machines, etc.) require high-speed rotation of the tool or spindle to generate heat, which also generates a large amount of heat during the cutting process. The parts that usually require cooling in these machine tool equipment, such as the spindle, cutting fluid, lubricating oil, hydraulic oil, electrical control cabinet, etc.
D， Non cutting machining
Such as electric discharge machines, polishing machines, grinding machines, etc.
When using a small chiller unit, the water system is prone to blockage by some iron filings, so it is necessary to install a filter.
Need an internal and external circulating water pump system or a closed water tank system.
