TS-DD series cold water machine
Cold water machine, also known as freezers, chillers, refrigeration system according to the principle of low temperature and pressure liquid refrigerant in the evaporator inside and around the water heat exchange evaporator heat absorption of water, evaporated to low temperature and pressure gaseous refrigerant temperature evaporation process constant, low temperature and pressure gaseous refrigerant into the compressor, compressed by the compressor.
It is compressed into a high temperature and pressure gas, and then into the condenser, the condenser in heat exchange with the interior of the medium, part of the heat of the high temperature and high pressure gaseous absorbed by the media, media temperature, refrigerant heat condenser into a high temperature and high pressure liquid condenser process temperature is constant, then enter the expansion valve throttling, throttling the rapid cooling process, the liquid refrigerant into a low temperature and pressure , this process again after the refrigerant into the evaporator and the evaporator heat exchanger.
The refrigeration system in order to achieve the process of this cycle is carried out continuously, the water was able to continuous cooling.

Pump overload
Fuse protection
High-voltage protection
Abnormal alarm protection
Phase protection
Application:
1, UV curing machine:
Features: stepless dimming + water cooled metal halide = + + + Low energy-efficient, water-cooled indoor lights (Kawamoto chiller chilled water) + air-cooled exhaust heat lamp below the installation of insulation quartz glass, effectively reducing the illuminated surface temperature, protect the dried goods will not heat deformation, extend lamp life; CBE for water-cooled series: offset, gravure, flexo printing machine, glazing coater.
2, ultrasonic cleaning machine:
Ultrasonic wave in a liquid, the liquid in each bubble burst will have a great shock wave energy, equivalent to instantly generate hundreds of degrees of heat and up to thousands of atmospheres, a phenomenon called "cavitation" ultrasonic cleaning is the liquid bubble burst with shock wave generated to achieve the effect of cleaning and scouring inner and outer surfaces of the workpiece.
Second ultrasonic propagation in liquid, the liquid, together with the cleaning tank vibrating at ultrasonic frequency, and the liquid has its own natural frequency of vibration when cleaning the tank, the vibration frequency acoustic frequency, so people hear the hum.
Cleaning fluid optimum cleaning temperature 40-60 ℃, in particular if the cleaning effect of low-level liquid temperature difference in cold weather, the cleaning effect is also poor. So some washing machine in the wash tank outside around the heating wire temperature control heating, when the temperature rises cavitation-prone, so cleaning is better. When the temperature continues to rise, increasing the gas pressure within the vacuole, causing the impact sound pressure drop, reflecting the synergistic action of these two factors.
3, the plastic industry
Extrusion blow molding injection compression molding blown film, rolling film
Standard industrial chillers can apply the above-mentioned industries.
A, injection mold cooling
Melted by heating plastic pellets injected into the mold, after condensation, mold ejection of the molded plastic parts, there is need to use the mold is cooled in a continuous production process to reduce the plastic setting time and improve the dimensional accuracy of the workpiece, forming quality, surface quality .
Cold water temperature requirements: 6 ... 18 ℃
Cold water temperature requirements: ± 2K or ± 0.5K
B, extruded
Extruded pipe, trunking, cable and all kinds of plastic profiles.
After a cold water bath, cold water bath water temperature must be kept constant by heating to melt the raw material after molding.
Due to the high production speed, due to surface need large capacity chillers.
Because if there are frozen pool is large enough, the unit may not deserve tank.
C, blowing
Mainly produce various kinds of mineral water bottles, soda bottles.
Compressed air - blowing required a clean, dry compressed air, the use of industrial chillers provide cold water for cooling the compressed air source can be removed in the water.
Mold cooling - chillers can accurately control the mold temperature, improve product quality, increase productivity
Compressed air drying and mold cooling can use the same water cooler as a cold source
D, thermoformed
The most common products for a number of small containers such as yogurt cups
Plastic is heated at a constant frequency die extrusion, to maintain a constant temperature is very important for the chilled water temperature range requirements are very high, and therefore requires a proportional valve from the cold water, but to precisely adjust the temperature.
E, the hydraulic system
Mold, mold, injection materials are required to complete the hydraulic system, hydraulic pump oil absorption of energy the temperature rises, the oil temperature is usually not higher than 60 ℃.
Cooling water temperature of about 27 ℃ more appropriate, due to the requirements of the mold temperature is not the same, requiring electric valve with mold cooling circuit or need a separate independent cooling system.
4, machinery industry
A, laser technology
Laser laser (laser) systems generating source, beam controller and the cabinet may require additional cooling.
Of cold water temperature requirements are usually between 15 ... 22 ℃, accuracy of cold water is usually ± 1K or ± 2K. Some devices may require ± 0.5K,
Also part of the equipment of cold water conductivity, corrosion resistance, etc. have certain requirements.
Laser systems typically start water temperature there are certain requirements, which will require an increase in electric heating water circuit.
In the part of the system of the beam controller will require separate cooling circuit.
Laser systems for special applications, can specially designed industrial chillers to meet different requirements.
B, welding
Electrodes, welding furnace and cutter etc. need to be cooled.
Such as large and medium-sized welding electrode tip cooling; gold and silver jewelry processing furnace cooling
Usually small to medium-sized chillers.
Need external circulation pump system or a closed tank system.
C, cutting
Many cutting machine tools (machining centers, lathes, milling, drilling, etc.) requires a tool or spindle rotation speed generates heat in the cutting process also generates a lot of heat. In these machine tools generally it is cooled spindle part, cutting fluids, lubricating oil, hydraulic oil, cabinet and so on.
D, non-cutting machining
Such as EDM machine, polishing machine, grinding machines.
When using water chiller system of turning some of the iron is blocked, because some necessary filters installed.
Need external circulation pump system or a closed tank system.
