Everyone may encounter many problems in the process of using the ultrapure water machine. So what causes the ultrapure water machine to discharge waste water all the time? Let me tell you about this problem:
1. The high-voltage switch fails
After the equipment is full of water, the on-press power switch should jump up to cut off the switching power supply. If it does not work, the equipment will continue to work, resulting in a constant flow of waste water. Resolution method: Turn off the pressure tank gate valve and the pump is working again. It must be that the high-voltage circuit breaker is not working well and needs to be replaced at this time.
2. The inlet solenoid valve fails
After the equipment is full of water, the pump stops working, and the water inlet solenoid valve should be disconnected for water seepage. At this time, if the sewage port keeps flowing, it may be that the water inlet solenoid valve is not working. Resolution method: turn off the water seepage gate valve, the sewage is terminated, it can be sure that the water inlet solenoid valve is not working, and it can be replaced.
3. The check valve fails
After the equipment is full of water, the pump stops working. If the check valve does not work, the person in the pressure tank will flow back to the RO membrane shell and discharge it according to the sewage port. Resolution method: turn off the pressure tank gate valve, the sewage is terminated, it can be confirmed that the check valve is not working, just replace it.
1. Ultra-pure water machine refers to the water treatment equipment that removes or reduces the hydrochloric acid salt (mainly the strong electrolyte that dissolves the water) to a certain level. The pure water resistance (25℃) produced is generally 1.0-10.0μS/cm, and the salt content is 1-5mg/L.
2. Ultrapure water machine is a kind of water treatment equipment that uses multi-level filter elements to carry out sewage purification and solves the physical methods of multi-application, such as filtering, absorption, and reverse osmosis without adding compounds. According to the precision of ultrapure water purifiers, it can be divided into two categories: ultrapure water purifiers for daily life consumption, also called household water purifiers, and ultrapure water purifiers for laboratory use that can meet the requirements of laboratory pure water.
3. The suspended matter in the filter water, heavy metals, germs, virus infections, etc. are all removed. It has a high filter technology. Household water purifiers generally have four or five levels of filter, and the first level is a pp cotton filter. The second and third grades are activated carbon (a well-made manufacturer can combine the second and third stages into one), the fourth grade is RO reverse osmosis membrane, and the fifth grade is precision activated carbon. Improve the taste, so the ultra-pure water machine is more suitable for areas with more serious water pollution.
