Entering the winter, there may be problems with pharmaceutical purification water equipment and how to deal with them

【Pharmaceutical Network Technical Article】Entering November, I believe that there are already many small partners in northern China who have felt the attack
of cold air.
According to China Weather Network, at present, most of China's northeast and northwest regions have entered winter, and Huanghuai in North China has begun autumn and winter conversion
.
As the temperature drops, pharmaceutical purified water equipment is prone to some problems, which can affect the production schedule
.
Pharmaceutical purified water equipment is used to meet the needs of drugs, medical devices and other industries to prepare purified water equipment, the normal operation of the equipment is to ensure the stable output of purified water premise
.
So, what are the possible problems of pharmaceutical purified water equipment in winter? And how to deal with it? First, the AC contactor fails
.
This situation is mainly because the damage of the contactor causes the main engine water pump to not start, thereby affecting the operation of the reverse osmosis equipment, and the solution is to replace the new AC contactor
.
Second, the pump can not start normally, or the pump is damaged, in response to this fault, the technician suggests that you can press the AC contactor, manually suction and close, if the pump can run can eliminate the pump failure
.
Third, the level controller is damaged
.
In purified water equipment, the level controller is an important control element, and if damage occurs that causes the equipment to fail to start, it needs to be checked to eliminate the problem
.
Fourth, the host cannot be started
.
The pressure switch ensures the water supply pressure of the main engine of the purified water equipment and ensures the normal operation of the pump, if the pressure switch is set incorrectly, it will cause the host to not start, so when using the pressure switch, it should be ensured that the setting is correct
.
Fifth, the water output of the equipment suddenly becomes smaller
during use.
There are many reasons for this situation, most of which are caused by the equipment filter element not cleaning for a long time, so the filter element can not be replaced for a long time, if the filter element is blocked, each filter element should be replaced as soon as possible
.
However, there are special cases in winter, because the water temperature will drop in winter, the viscosity and fluidity of water will slow down, which will also cause the water production of purified water equipment to decrease
.
The technician said this was normal
.
Sixth, the equipment is frozen, due to the cold climate, the equipment is easy to be frozen if it does not do warm measures, so it is very important to
do a good job of antifreeze of purified water equipment.
Technicians remind that in a cold environment, attention should be paid to the insulation of purified water equipment pipelines, RO membranes and pumps, and it is recommended that the room where pure water production equipment is placed is not lower than 0 degrees, and the indoor temperature is controlled
.
When the purified water equipment is in operation, a detailed operation record table should be made to facilitate the viewing of the cause of the failure and solve the problem
in time.
For the temporary non-use of the equipment, it is necessary to discharge the water in the equipment pipeline cleanly, such as opening the flange, union, and valve to let the water flow out
naturally.
For the case of non-use of the equipment for a long time, it is necessary to close the water inlet ball valve, discharge all the water in the pressure barrel, check whether the appearance of the machine is normal before using it again, confirm that it is normal before connecting the water source power, and the first bucket of water prepared is also recommended to be
discharged.
In addition, in winter, it is necessary to regularly inspect the purified water equipment to see if any parts are frozen and do a good job of treatment in
time.
If you encounter freezing, be sure to thaw it before you produce
it.
