Common problems and maintenance methods of closed cooling tower fan

Fan is one of the important components in the operation of closed cooling tower. Strict compliance with the effective maintenance plan of this component is beneficial to improving the refrigeration efficiency of the closed cooling tower, reducing energy consumption and noise. The manufacturer of closed cooling tower will disconnect the switch power supply of fan motor when checking the fan. Sometimes, it is very risky for the fan to suddenly run because of self starting. In addition, it is very risky to disconnect the switching power supply bit by bit when shutting down, and suddenly run the fan when repairing the power supply system

What are the types of packing for closed cooling tower? What are the performance characteristics?

The vacuum pump is charged and formed. The unique packing ensures high efficiency of heat exchange. Simply speaking, the effect of the filler in the closed cooling tower is to enhance the heat removal and heat exchanger. The equipment temperature caused in the whole process of industrial production or refrigeration has excellent film performance and differential sine wave packing, and its raw materials and processing technology are very harmful to the refrigeration efficiency. The cooling tower packing is divided into S-wave packing with low negative pressure. Good flame retardant self extinguishing type, good ductility of raw materials, high volume dispersion index, increased retention time of cooling circulating water, and high refrigeration efficiency. The flame retardancy of hexagonal honeycomb filler shall comply with the requirements of GB/T2406-93 of the Ministry of Public Security. There are various types of fillers, which are generally correctly guided by cooling circulating water. The service life of closed cooling tower packing is generally more than ten years. It is not necessary to fill the tower with items that must be cooled. The closed cooling tower packing is the most important part of the cooling tower. The point wave packing will convection waste heat to the gas and disperse it into the air. The packing of closed cooling tower has a large bearing capacity. The performance characteristics of double wave packing are mainly reflected in the following nine aspects. The regulations on the software of industrial production water system are gradually improved, which is not easy to block, and the bearing capacity per square meter exceeds 3.5KN.

How often should the water tank of the closed cooling tower be filled with water?

The water volume of the water tank of the closed cooling tower shall be noticed during normal operation. A ball valve shall be installed in the water collecting tank of the closed cooling tower to monitor the water volume. In general, we give an early warning on how much water needs to be replenished according to the float valve. As long as it is lower than this basic point, a request for water replenishment will be issued, and then water replenishment can be carried out. At the same time, a maximum water replenishment line is set, which can not exceed this amount. Then, users of the closed cooling tower will ask, is the amount of make-up water large? Is the cost high? In fact, there are several factors for the water supplement amount of closed cooling tower: the load of the closed cooling tower unit, the temperature around it during operation, whether it is in the south or in the north at this time, and which season is spring, summer, autumn and winter in the current season. In general, the higher the temperature is, the greater the water supplement amount will be; on the contrary, the smaller the water supplement amount will be. Of course, compared with the open cooling tower, the closed cooling tower has an absolute advantage in terms of energy saving and emission reduction. Why do you say that? Closed cooling towers use circulating pumps to circulate cooling water. In contrast, the closed environment is much larger than the open cooling tower. In this way, the water is not easy to evaporate to the outside environment, so the natural amount of make-up water is less. Based on the above description, if the user still wants to ask how often to add water to the water tank of the closed cooling tower? In general, the water supplement amount of the closed cooling tower is determined according to the operation of your on-site equipment. Simple operation is to supplement water in time according to the feedback information controlled by the ball valve, which is simple and convenient.

Installation of closed cooling tower and cooling circulating water management method

In order to make full use of the effectiveness of the cooling tower, a good installation site should be selected, that is, a naturally ventilated and clean area; The cold and wet gas discharged from the cooling tower is not easy to be sucked into the site of the cooling tower. Avoid the application in the natural environment with many floating dust and acid gas, or it will cause erosion of the heat exchanger and the pipe, and prevent the application in the smoke window and the source of pyrogen radiation.

What are the best technical key aspects of closed cooling tower?

What are the key technical aspects of excellent closed cooling? First, the reverse flow closed cooling tower is covered with water. The water flows from top to bottom and the gas flows from top to bottom. The two are thermally converging with each other. The heat supply characteristic of the return cooling tower is good, and it is divided into three refrigeration sections: ① The rotary nozzle is located in the indoor space at the top of the filler, which is high in temperature, so it can still discharge heat to the gas. ② Part of the heat exchanger filled with water and gas. ③ The cooling water added to the indoor space of the water collecting reservoir is called "tail effect".

How many pumps do closed cooling towers need?

How many pumps do closed cooling towers need? It is impossible to immediately respond to this problem. In the case of the overall design scheme of closed cooling tower, in the refrigeration plan presented by the customer, water pumps are generally provided according to the specific situation. The total number of water pumps is related to a series of factors such as the refrigeration temperature, the refrigeration water flow, and the circulation system status. In the case of the design scheme, the number of water pumps cannot be too high, otherwise it will be a waste of electromagnetic energy. If it is too low, the regulations for cooling circulating water cannot be met, and the final refrigeration regulations cannot consider customer satisfaction. In addition, attention should be paid to environmental protection and energy conservation.

Cooling range of closed cooling tower (basis for selecting supplier of cooling tower)

When purchasing closed cooling tower, most equipment purchasers will be very concerned about one question: how much is the cooling range of your closed cooling tower? Then, from the practical point of view, this question is very broad and cannot be answered without any reality. For example, if your water temperature is 70 ° C, if our closed cooling tower reduces it to 30 ° C, then our cooling range will reach 40 ° C. If the water temperature is 50 ° C and I also reduce it to 30 ° C, then my cooling range will be 20 ° C. Does this mean that there is a problem with our closed cooling tower? Right!

Requirements for inlet water temperature of closed cooling tower

Requirements for inlet water temperature, lost cooling water volume and temperature adjustment method of closed cooling tower The water loss of the closed cooling tower is the key parameter for water saving operation. The amount of water loss in the cooling water depends on the amount of water loss in the cooling water. The water loss of the cooling tower includes volatilization loss, wind blowing loss and sewage treatment loss. Volatilization loss is unavoidable; The wind blowing loss means that there are water droplets in the cyclone discharged from the closed cooling tower that are slightly blown out of the tower by the wind; In addition, the waste water treatment loss of the closed cooling tower is to prevent the water from being carried away by the cooling reservoir due to the solid solubility from generating scale.
