Maintenances for the TOP WATER CHILLER

The service life for the water chiller unit mostly depend on the good working condition and maintenece for the chiller system. For the Chiller, below points should be noted for the maintenance
1.The refrigerating water pump should not work if there is no water in the water tank; (For the chiller unit above 7.5 HP, there is a built-in water level protector in the water tank. While the water level is too low or the tank is empty, the water pump will be stopped automatically, and it displays the water-level fault code and alarm.)
2. The operating switches should be avoided frequently switching over. Pls turn off the main power when the machine did not work for a long time.
3. While the refrigerated-water temperature reaches to the set temperature, the compressor will stop.
4. In order to prevent the evaporator freezing, do not set temperature below 5℃;( except the low temperature chiller), Pls drain out the chilled medium off the machine when it did not work for a long time.
5. To make sure the best cooling efficiency and best working condition of the unit, please clean the condenser, evaporator and the water filter regularly, and confirm there are no adulterant and other obstruction.
6. Please turn off the chiller while it is alarming. And start chiller after the failures are removed according to the way stated in the Mannual.
7. Good ventilation and clean working condition will be better for the operation of air cooled chiller as along as keeping in high cooling efficiency.

Development of bottle blowing machine

Hollow plastic containers with lightweight and inexpensive , safe and other characteristics, widely used in beverage , pharmaceutical, cosmetics, food and chemical industries , is attracting more manufacturers choose plastic containers instead of glass containers in the past . Today's plastics industry 's most advanced equipment , molds and raw materials, all unfolding in front of us , new technologies, new applications emerging , look at the field of plastic blow molding is also fruitful. With world oil prices soaring, plastic raw materials prices are high, the development of low energy consumption, alternative raw Province is one of the market trends. Bottle blowing machine is the most simple and obvious explanation is capable of plastic granules ( softened into a liquid ) or do a certain process preform by means of blown bottle machine.
CNC ( CNC machining center ) is a computer numerically controlled machine tools (Computer numerical control) for short , is a program-controlled machine tool automation . The control system can logically process control codes or other symbols with the provisions of the directive , it is decoded by a computer , allowing the machine to perform a good action prescribed by the cutting tool material will be processed into semi- finished parts blank . Its advantages are:
● high precision , with high processing quality ;
● can be multi-axis linkage , can process complex shape parts ;
● When machining parts changed, generally only need to change the NC program can save production lead time ;
● High precision machine itself , rigidity, choose the amount of favorable processing , production rate ( generally 3 to 5 times that of ordinary machine tools ) ;
● High degree of automation tools , can reduce labor intensity ;
● mass production , product quality and easy to control ;
CNC machining is widely used in all areas of machining any , is the development trend of mold and important and necessary technical means.

Development prospects of Metal Laser cutting machine

The original Chinese name is called laser "laser", "Lasse" is its English transliteration of the name of LASER, is an acronym derived from the English Light Amplification by Stimulated Emission of Radiation each word consisting of the first letter. Meaning "by stimulated emission of light expanding." Laser full name in English has been completely express the main laser manufacturing process, the principle of the laser has been found as early as in 1916 the famous American physicist Albert Einstein. According to China in 1964, the famous scientist Qian proposed that "light by stimulated emission of radiation" was renamed "laser." Laser applications is very wide, there are laser marking machine, fiber optic communications, laser spectroscopy, laser rangefinder, laser radar, metal laser cutting machine, laser weapons, CD, laser pointer, laser vision correction, cosmetic laser, laser scanning, laser mosquito and so on.
The Metal Laser cutting machine is a laser using a high power density laser beam scans over the surface of the material, the material is heated in a very short time first million to several thousand degrees Celsius, melting or vaporization of the material, then the high pressure gas or vaporized material molten cracks blown away from the cut, to achieve the purpose of cutting material.
Laser marking machine (laser marking machine) with a laser beam the surface of a variety of materials marked with a permanent marker. Laser marking with a laser beam the surface of a variety of materials marked with a permanent marker. Marking effect evaporation surface material is exposed through the deep substance, chemical or physical change through energy cause the surface material and "carved out" signs, or part of the material is burned by light, showing the required etching patterns, text.
In modern society, the role of information and more important, who has mastered the more rapidly the information, the more accurate, more abundant, more who will take the initiative, will have more chance of success. Appeared laser triggered an information revolution, from VCD, DVD disc to the laser illumination, the use of laser greatly improves the efficiency and convenient for people to save and retrieve information, "Laser Revolution" significance. Controlling the time and space controlled well laser, the material of the object, the shape, size, and have a great degree of freedom in the processing environment, especially suitable for automated processing, laser processing systems and computer numerical control technology combine to form a highly efficient automated processing equipment, timely production enterprises has become the key technology for high-quality, efficient and cost-effective processing opens up broad prospects. 2013, laser technology has been integrated into our daily lives, and in the coming years, the laser will bring us more miracles.
