The use of water curtain fans to cool down workshops has always attracted attention. Practice has proved that for some workshops that do not use water curtains for cooling, the temperature is 5% to 6% higher than those that use water curtains. When the outside temperature The higher the value, the more obvious the cooling effect. However, what should we pay attention to when using it? Let us find out together below!
Water curtains can easily breed moss and other algae when exposed to sunlight, causing obstruction. Therefore, sunlight must not be directly irradiated on the water curtain. At the same time, do not use transparent water pipes, filters, etc. It is also necessary to avoid impurities adhering to the water curtain or water circulation system, because any pollution problem may cause serious consequences and affect normal use. In winter, the outside of the water curtain can be covered with plastic paper, which can not only keep the workshop warm, but also prevent dust and insect netting.
Warm reminder: The water curtain fan must clean the filter of the water curtain system every week. Never use chemicals containing chlorine or bromine to wash the water curtain. The pool water must be changed every week, every three Drain, clean and disinfect the entire cooling water system every month. Detailed introduction of the green and environmentally friendly wet curtain: Nano antibacterial characteristics: On the basis of maintaining the functions of the standard wet curtain, the use of nanomaterials can effectively inhibit the growth of bacteria and keep the air fresh and natural for a long time. Deodorizing characteristics: On the basis of maintaining the function of the standard wet curtain, adding special aromatics can not only prevent the growth of algae, but also make the air fresh, natural and fragrant.

2; Daily maintenance of the negative pressure fan:
(1); Clean the impurities in the protective net,
(2); Check the softness of the belt, if If any looseness is found, arrange for adjustment and reset immediately.
(3); Check whether there is any abnormal noise in the bearings of the motor. If so, check whether there is still lubricating oil on the motor! Evaporative cooling pads are very durable products. In order to ensure the longest life of the wet curtain and maintain optimal efficiency, please use it under correct installation and usage conditions.
When stopping use:
Before shutting down the machine every day, cut off the water source and let the fan continue to run for 30 minutes or more to allow the wet curtain to dry completely before shutting down. This is beneficial. Prevents the growth of algae, which can clog water pumps, filters and water distribution lines.
Algae can grow on any light, moist, exposed surface. Here are some suggestions for preventing its growth:
(Chlorine and bromine are two very common chemicals that prevent algae growth. But they are The wet curtain core is potentially harmful and should be used with caution;)
Do not use open pond water;
Use water with good quality;
< p>Cover the water supply tank to prevent exposure to sunlight and entry of dust in the air;Let the fan run for a while after cutting off the water source;
Water self-supply system and other The system is isolated;
The wet curtain avoids direct sunlight.
Water quality
The PH value of circulating water is maintained between 6-9 (a PH value of 7 is pure water). If the pH value is too high or too low, it will damage the wet curtain; the calcium carbonate precipitate contained in hard water will not damage the wet curtain, and it needs to be kept within a limited range. If the sodium chloride (soft water) concentration exceeds (or approximately) 50,000 ppm, Salt substances will precipitate on the wet curtain, thereby reducing the air flow through it; the concentration of salt in the circulating water must be within 50,000 ppm, and the concentration of salt in the mixed water must be within 40,000 ppm.
Cleaning
If airborne dust tends to block the passage of airflow, normal operation of the system can usually clear these obstructions. If necessary, use low-pressure steam spray or gentle scrubbing. Never use chlorine or other pungent-smelling chemicals for cleaning.
Proper water level
Do not overflow the water in the system. If the water level is too high, the bottom of the wet curtain will always be soaked in water and become over-watered, which will affect the self-watering system of the medium and shorten its service life.
Maintain drainage
As water continues to evaporate and new water is constantly replenished, salts and minerals are retained during the water cycle. In order to reduce the formation of sediment and scale, an automatic drainage device is needed, because the drainage rate is 5% to 10% of the evaporation rate, and the evaporation rate mainly depends on the hardness of the water and the level of air pollution. The drainage rate under normal operating conditions should be 20% of the maximum evaporation rate under poor conditions.
Make water evenly distributed on the wet curtain
Control the water supply by adjusting the water pump. Clean the pool, water pump inlet, filter and water pipes, etc. Remove dirt from inside each water circulation system.
Annual shutdown
At the end of each quarter, drain the water in all water pumps, water tanks, water storage rooms, and wet curtains. If some water remains in the system, it will accumulate precipitation and produce algae. When it is used next time, it will block the holes in the water pump, water distribution pipe channels and wet curtains.
