How often do we need to hand in the circulating water to the closed cooling tower?

Jiangsu Yunuo Cooling Technology will introduce to you how often we need to hand over the circulating water to the closed cooling tower.
The main principle of the closed cooling tower is that the spray water evaporates on the outer wall of the coil to cool the fluid in the pipe, and the fan is used to take away the generated water vapor in time. A small part of the spray water evaporates, and the rest is collected and circulated by the chassis. In addition to being used in air conditioning systems, closed cooling towers can also be used in metallurgy, chemical, petroleum and other industries. But its use also increases production investment and work costs. Therefore, it is necessary to optimize the design, and then achieve the purpose of economical energy saving.
Coolant optimization, different coolants have a very important and decisive effect on the cooling effect of the closed cooling tower. The working environment of the closed cooling tower (environmental optimization), the installation of the closed cooling tower in a ventilated environment can effectively improve the work efficiency and facilitate the air circulation in the tower.
The V-belt of the blower may be slightly stretched when it is working for the first time. Please adjust the belt tension properly according to the adjustment method. If it is too tight, it will damage the bearing and cause an accident. The upper sink water hole and the lower sink filter should be cleaned regularly once a month. Please loosen the belt when it is not in operation, add oil to the bearing part of the blower, and cover the motor. At the beginning of work, confirm the tightness of the belt, tighten the nut, and add oil to the bearing part of the blower. Others should also confirm whether there is a bird's nest or foreign matter in the tower, and then start the work again. Communicate circulating water at least twice a year.
After the circulating water evaporates, the dissolved substances in the water will be left, which will increase the water concentration. After the water is concentrated, the corrosiveness and scale will increase, so that the cooling tower can be lowered, and the piping and equipment will be damaged. In order to prevent this situation, it is recommended to use the method of releasing part of the circulating water. In order to prevent the freezing of the copper pipe (radiator) and the distribution water of the closed cooling tower, please pay attention to these points, in order to prevent the freezing of the circulating water , please add antifreeze in circulating water, or add auxiliary antifreeze electric heater in piping. After adding antifreeze, the freezing temperature drops, and it is not easy to freeze. The higher the concentration of the antifreeze liquid, the lower the freezing temperature, but the thermal conductivity will decrease. Therefore, attention should be paid to the selection of cooling towers. If other water leaks, the antifreeze will be diluted when adding water, and the freezing temperature will rise, please pay attention. When the circulating water pump of the closed cooling tower is working, the antifreeze electric heater is heated, and the water will not freeze. If there is an occasion where the circulating water pump is stopped, the circulating water pump needs to be supplemented. Here we recommend the use of a complete set of antifreeze (including auxiliary circulating water pump, antifreeze electric heater, and piping). The circulating water system is equipped with a 3-directional valve. When the circulating water is used to control the capacity through the bypass pipe, if the flow rate of the bypass pipe is increased, the flow rate in the copper pipe will decrease, and it may freeze even when there is a load. Please set a small amount of circulating water in the cooling tower.
In order to prevent the freezing of the water pump and the water distribution pipe, please use an antifreeze electric heater to maintain the temperature of the lower water tank.
