Chiller is a water cooling equipment, can provide constant temperature, constant current, constant pressure cooling water equipment, its working principle is to first into the machine into a certain amount of water tank, through the cooling system will be water cooling, and then by the pump will be low temperature Cooling water into the equipment to be cooled, chilled water will take away the heat after the temperature rise and then back to the tank, to achieve the role of cooling. However, in the use of chillers for a long time, chillers or tanks often have some dirt deposits, then how are these sediments come from?
1, chemical processor pharmaceutical
Such as in the water cycle system plus zinc salt or sentence phosphate corrosion inhibitor, there are zinc or phosphoric acid scale formation. So we should always on the chiller maintenance work, not only to ensure its cooling capacity, but also can extend the service life of chillers.
2, the disclosure of process media
Water cooler leaks, especially oil spills or some organic matter that causes deposition of sludge.
3, tap water
Untreated poor water will be sediment, microorganisms, suspended solids into the chiller, even if the clarification, filtration, disinfection of good water will have a certain amount of turbidity and with a small amount of health, clarification process It is also possible to mix the hydrolyzate of the mixture, aluminum or iron ions in the replenishment. In addition, regardless of whether the pretreatment, replenishment of dissolved salt will be brought into the circulating water system.
Sediment, dust, microorganisms and their spores will bring the air into the circulatory system, and sometimes the insects will bring into the system, causing the heat exchanger blockage. When the cooling tower around the surrounding environment is contaminated, hydrogen sulfide, chlorine dioxide, ammonia and other corrosive gases will react in the unit and indirectly caused by deposition.
