The purified water equipment fails to produce water, what is the matter?

[Pharmaceutical Network Technical Article] In the pharmaceutical production process, special purified water equipment is often required to produce water
.

Purified water equipment can effectively remove impurities and desalination.
It has the characteristics of stable and reliable water production, easy operation, low operation and maintenance costs, and environmental protection.
It can meet the needs of medical testing water, biopharmaceutical water, and medical supplies water in the pharmaceutical industry
.

In recent years, with the rapid development of the pharmaceutical industry and the improvement of GMP requirements, the demand for purified water equipment in water treatment has gradually expanded, and the development prospects are broad
.

At present, the purified water equipment products on the market cover a wide range, and major enterprises are also seizing the opportunity to continue to make efforts to create more purified water equipment that can meet the high-standard water demand in pharmaceutical production and other fields, and escort the high-quality development of the pharmaceutical industry.

.

It is worth mentioning that in the process of using purified water equipment, some problems often occur, such as performance deterioration, excessive water supply, sharp rise in pressure difference, reduction in salt removal rate, decline in water quality and even failure to produce water, etc.
The situation has brought obstacles to the water production process of pharmaceutical enterprises
.

Recently, some users said that their purified water equipment could not produce water.
What is going on? Some purified water equipment manufacturers responded that the equipment cannot produce water and needs to be analyzed in two cases, one of which is for the case where the high-pressure pump can work normally, and the other when the high-pressure pump cannot work normally
.

 　　Among them, for the situation that the high-pressure pump can work normally but the water production failure occurs, it is necessary to carefully check whether the high-pressure pump of the equipment has a pressure loss failure, and whether there is a problem with the water treatment accessories and consumables
.

If there is a fault, further treatment is required to meet the requirements of normal water production; if the user finds that neither waste water nor pure water is discharged or only a small amount of waste water is discharged during inspection, it may be that the pre-filter is blocked and needs to be corrected.
The pre-filter is dredged
.

However, if only waste water is discharged but no pure water is discharged, this situation is generally caused by the blockage of the check valve.

.

 　　In addition to the above exclusion methods, if the solenoid valve fails and cannot be started effectively, there will also be a situation where water cannot be produced
.

Therefore, the user needs to check the solenoid valve, and deal with it in time after finding the problem
.

 　　The industry pointed out that although the failure of purified water equipment is very common, if users do not pay attention to maintenance during normal use, it will be difficult to ensure the continuous and stable operation of the equipment, not to mention improve the water quality of the equipment, so this also reminds users that it is necessary to strengthen Equipment maintenance work
.

 　　So, how to maintain the purified water display? On the one hand, it is necessary to arrange relevant staff with professional skills to regularly clean the purified water equipment to remove dust, oil stains, dirt and other substances on the surface of the equipment, and at the same time, check the equipment regularly, regularly and at fixed points to ensure that all devices in the water system are in good condition.
, which can also detect potential failures in advance and deal with them in time
.

 　　On the other hand, it is also important to replace the consumable materials in time
.

Some manufacturers' technicians said that they can regularly replace consumables such as filter elements according to the condition of the raw water and the preset replacement cycle of the system
.

"According to the use of the equipment, some parts are disassembled, cleaned, repaired or replaced to ensure that each component of the water system is in good operation and improve the water quality
.

For example, the filter element of the security filter usually takes 1 to 3 months.
Disassemble and wash, if the treatment effect is still poor after disassembly and washing, it is recommended to replace it
