What is the reason for the slow speed of large ultra-pure water equipment?
The correct operation and reasonable maintenance of large ultra-pure water equipment is the premise to ensure its normal operation. In general, after using large ultra-pure water equipment for a period of time, many people may find that the water production of the equipment is slow, which is also a problem that many customers are more puzzling. This article is about the reasons for the slow production of water in large ultra-pure water equipment.
The reasons for the slow water production of large ultra-pure water equipment are as follows:
1. Blockage of membrane
The pre-filter filter is not changed and cleaned for a long time, resulting in the water quality inside the machine is far worse than the water quality before entering the machine. The raw water quality is poor, the proportion of waste water is small, resulting in the blockage of the wastewater solenoid valve or the washing combination valve, and then no waste water, or very little waste water, which leads to the blockage of the membrane, and the service life of large ultra-pure water equipment becomes shorter.
2. The transformer is faulty
The transformer is faulty, can not provide the voltage required for normal pressurization of the pump, the speed is slow, the increased pressure is small, the pressurization is small, and naturally can not reach the pressure required for tap water to pass the RO film, at this time, the water production is slow. The industry said that after excluding the main factors affecting the slow water production such as the pump factor and the membrane factor, it is necessary to replace a new transformer to try.
3. The check valve is blocked
Sometimes the check valve will be blocked, although this is rare, but when we check, we can take off the check valve to see the water output. If there is a significant change in the water output after and before removal, it means that the check valve is really blocked.
4. The filter element is blocked
At present, the secondary pollution of tap water is becoming more and more serious, if it catches up with the maintenance of the pipeline, the filter element can be said to be blocked. In industrial production, if there is a lack of special maintenance, the filter element is rarely replaced, so the blockage is very common. Replacing the filter element is very important to extend the life of the equipment, and personnel should be arranged for regular maintenance and replacement to ensure that it is unimpeded.
5. pump pressurization is small, pump pressure loss
Pump pressure is small, generally appear in the service life of more than two years of equipment, or long-term in the working state of equipment. Pump pressure loss, generally not easy to find. The direct manifestation is that the membrane water is less or the membrane does not water, which is often mistaken for a blocked membrane.
Large ultra-pure water equipment is the use of pretreatment, reverse osmosis technology, ultra-purification treatment and post-treatment methods, the conductive medium in the water is almost completely removed, and the water does not dissociate colloidal substances, gases and organic matter are removed to a very low degree of water treatment equipment.
