' Pure water Machine ' is a commonly known, many places also called RO reverse osmosis water purifier, or RO reverse osmosis water purifier. Reverse osmosis water purification mechanism of the cause of slow, many people attributed to the RO membrane blocked, to change the film.
In fact, there are other reasons why water is slow.
Reason one: membrane blockage
Factors that affect membrane clogging: 1, the membrane is used for a long time, some have been used for two years, three years, or longer. According to the instructions, the lifespan of the film is 1.5 to two years.
The life of the membranes takes into account water consumption and the water quality factors, water consumption and raw water quality and membrane life is generally proportional.
2, the front filter core is not changed for a long time, resulting in the internal water concentration of the machine, far worse than the water before entering the machine.
3, the raw water quality is poor, the proportion of concentrated water is small, resulting in dense water solenoid valve or flush combination valve plug, and then the machine does not arrange the thick water, or the drainage is very few, then the short-lived film is expected. 4, the quality of the film itself is poor.
Like how low the price is, how low is the membrane of the rotten street, and what do you expect it to be?
Reason two: Filter plug A metaphor, water purifier filter like our body's ' kidney ', water purifier water quality depends not only on the quality of the filter, but also depends on the filter's service life is timely replacement, if the filter time is too long, and not to replace, will cause water jams, less water, long-time use will also cause the whole water purification system is contaminated , so users should develop a good habit of changing the filter regularly.
General Specification Water purifier manufacturers will not be the case of arbitrary charges, the cost of core replacement is not high.
Reason three: post-active cotton clogging This typically occurs after the replacement of a new post-activated carbon. Because there is more toner, there is no burst.
Therefore, the general granular activated carbon filter can not be too full (not to cut corners), to reserve the space for filling, on the one hand to ensure that the flow, on the other hand, activated carbon itself also has expansion coefficient.
Reason four: Low temperature Ro membrane water production speed and temperature have a great relationship, the hottest not more than 40 degrees, the lowest not less than 5 degrees. The general optimum temperature is 25 degrees. To 25 degrees, generally, the water yield will be reduced by 3% for each reduction. Therefore, winter than the summer of the water-making speed generally reduced by half or even more.
Rural users in particular need to pay attention to cold protection, sometimes winter will freeze bad filter bottle, membrane shell, thick water pipeline export winter also do not put in the outdoor.
Reason five: Pump booster Small Pump pressurization Small, generally appear in the service life of more than two years of reverse osmosis water purifier, or long-term working state of pure water machine. Pure water machine principle is driven by the pump to power through the reverse osmosis membrane needs the appropriate pressure, household water purifiers generally in about 6-7 kilograms, reverse osmosis commercial aircraft generally in 4 to 6 kilograms or so.
