When the vertical water heater is heated, it makes a loud noise. What's the matter?
3, the internal structure of drinking fountains:The water in the barreled water flows into the two water pipes through the hose of the water dispenser, one is a hot water bladder, and the other is a cold water bladder, and the two water pipes are provided with waterIn addition to the partition of hot and cold water, but also play the role of impurities in the precipitation of water, the problem is in the water base and hot and cold water inside the threeIn general, people usually drink only a bucket of water after they have finished drinking water, but they ignore the water dispenser in the process of changing waterThe liner will still contain nearly 1000 milliliters of water, and the longer it takes to drink a barrel of water, the more alarming the numbers of bacteria that carry the airPeople who have been disabled for a period of time or under high temperature and high humidity have two greater pollutionSome drinking fountains are prone to water accumulation, so dark and humid environment is very suitable for microbial growthGrown at 25 to 32 degrees Celsius, other microorganisms are suitable for breeding at 35 to 37 degrees Celsius, just as the room temperature is kissingThe purified water flows through the water intake with these molds and pathogens and is also contaminated. The bacteria multiply continuously, causing digestion,Urinary system and so on more than 50 kinds of diseases,
During the process of water exchange:The structure of most drinking fountains is generally reversed by the barrel of the barreled water, placed on the seat of the water dispenser, and filled with bottled waterAfter the machine, each release of a liter, there must be a corresponding volume of air entrainment of dust, Escherichia coli, Staphylococcus, fungi and so onA variety of bacteria also attached to the water dispenser, then the bacteria will continue to breed in the water fountain, yellow, sticky slip feeling, timeA long time can reach the degree of endangering human health
The scale is too muchThe so-called "two pollution" refers to bottled water pollution in drinking fountains, there are five main aspects:1, the working principle of drinking fountains:The water dispenser works with the principle of air pressure, and the water system is designed by the circulatory system adopting the principle of air pressureDifferent degrees of use of rubber tubes, plastic pipes and other chemical substances, coupled with air quality is getting worse and worse, the air acid base coefficient increasedLarge, serious oxidation of tubular products, resulting in the rubber hose, plastic pipes of the waste, resulting in white flakes, two pollution barrelsWater.
