Laser engraving machine, laser tube anti-freezing method

More cold than last year, this year in order to make their own laser equipment can work normally, please protect the laser tube! At present domestic most of the northern cities have entered the sub-zero temperatures, general water freezes will appear the phenomenon of the time. For the laser tube crack cause ice cooling fluid pipe scrap, today give you said the laser tube method and solution of antifreeze. Basic principle of laser engraving machine, laser tube antifreeze and methods: we all know that the liquid has its own 'freezing point', when the temperature of the liquid temperature is lower than the 'freezing point', the liquid will form a solid, and the laser tube commonly used coolant deionized water and purified water in the process of solidification get bigger size, this will 'hold' bad water cooling tube and sealing connection, causes the damage of laser tube. Laser tube for the laser tube, the liquid solidification cooling output head, water-cooled machine damage, has the following three solutions: 1. Such as local wouldn't power outages, the circumstance that does not work at night also not closed water cooling machine, at the same time to achieve energy saving, low temperature and room temperature to 5 - the temperature of the water - - - - - - 10 ℃, to ensure that the laser tube cooling fluid in the loop state and temperature below freezing. 2. Each downtime will be inside the laser tube, water cooling machine after using cooling liquid emptying. 3. Use antifreeze as a coolant. When laser machine power outages occur frequently use environment or do not have a day of emptying of coolant conditions, you must use antifreeze to antifreeze. The basis of antifreeze liquid composed of alcohol and water, not to corrosion of metal parts, rubber hose and so on laser machine accessories. When choosing or deployment of antifreeze, the freezing point of antifreeze should be about 5 ℃ lower than the lowest temperature using the environment. 1. Using ethanol for short-term frost: if power failure under the condition of cooling water, and cannot be emptying need temporary short-term frost, can join in deionized water or pure water ethanol ( Alcohol) , add the amount cannot be more than half of the tank volume. Because ethanol is corrosive is very strong, so cannot be used for a long time, must be emptying ethanol mixture in a week and use pure water or deionized water for cooling line cleaning, if still need frost must choose special antifreeze. 2. Using professional brand, dedicated antifreeze: well advised to choose a brand antifreeze, suitable for laser engraving machine system antifreeze generally has two types: 1) AntifrogenN glycol - Water type ( Industrial supplies, toxic) ; 2) AntifrogenL propylene glycol - Water type ( Food grade, harmless to the human body) 。 These two kinds of cooling fluid can easily buy. Note: any antifreeze can not completely replace the deionized water, can't continue to use all the year round. Etc. After the winter must use deionized water or pure water cleaning used coolant lines, and restore using deionized water or pure water as the coolant laser line. Water-cooled machine working condition or environmental permitting, or the power of the advice to improve my working environment, keep the water-cooled machine continues to run, or upgrade cooling waterway design, can be simple and rapid emptying water every day.
