The general troubleshooting method for water purifiers without water (1)
Jan 17, 2019

In the case of checking that the water purifier does not produce water, the valve must be closed. The water purifier is also called a water purifier. Generally, two kinds of households can change the water value to reach the standard of drinking water. This kind of water can change the water value. The machine is also called reverse osmosis water purifier, or pure water machine. It usually has five-stage filter. The first three stages are clean water, also known as wash water. The latter two stages change the water value through the fourth-stage reverse osmosis RO mode. One is an ultrafiltration machine, which is also composed of a five-stage filter, but it does not require electricity to make water. Let us introduce the pure water machine first.

This is the working principle of the pure water machine. We can clearly see that it enters the pure water machine from the three-way valve that the tap water has passed. The second valve that has changed the tap water into the machine is called the “decompression valve”. Highlight the point,




The function of the decompression valve: it can control the excessive pressure of the external water, so that the machine can not bear, it is easy to damage the various filter elements inside the machine. The most common is the fourth stage of the RO mode, the fifth level, if the water pressure is too large It is easy to cause damage to them. It has both advantages and disadvantages. When the machine in the home is used for a period of time, it is easy to cause it to clog. At this time, just check the clean water, that is, if the water coming out of the washing port is small or does not produce water, The decompression valve is blocked, and the removal method can be removed or the pressure relief valve can be removed or replaced.




Water through the decompression valve to our pure water machine first-stage filter PP cotton, also known as polypropylene PP cotton, the old machine is 8-9 inches are currently 10 inches, its role is to remove all visible water from the microfiltration membrane Things/dust and impurities. These particulate matter comes from the aging of pipes, rust, and secondary pollution of roof tanks. According to the water value of the tap water, the service life is generally 6-8 months.




The second stage is granular activated carbon. It is divided into several types according to the production raw materials: coconut shell granular activated carbon, coal granular activated carbon, and fruit shell granular activated carbon. The granular activated carbon is made of high quality anthracite as raw material and refined by advanced technology. Black amorphous particles; with developed pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, low cost, etc.; used for purifying bacteria in water, purification of industrial and domestic water, solvent recovery, etc. According to the local water value is generally 8-12 months replacement




The third stage is a carbon rod, also known as a sintered carbon rod filter. The sintering bonding technology has high filtration precision and good adsorption effect. It does not cause secondary pollution when used. The replacement time is generally 8-12 months. The water filtered out in the first three stages is pure water, which retains the minerals in the water and is best used for washing vegetables.
