Talking about the purchasing skills of cross-flow closed cooling tower

When purchasing a cross-flow closed cooling tower, the cooling tower must be accurately selected. After calculating the required cooling water volume, cooling capacity, power and other parameters, the correct selection and purchase can be made. There are many kinds of materials for the production of cross-flow closed cooling towers, such as aluminum-zinc plate, stainless steel plate, glass steel and other materials. Therefore, the cost should be considered when purchasing a cross-flow closed cooling tower. Today, the editor of okmarts.com will share with you the tips and requirements for purchasing a cross-flow closed cooling tower. I hope it will be useful to everyone!

　　 1. Choose according to the cooling fluid. Some cooling fluids are corrosive, so choose the cooling tower material and avoid chemical reaction with the cooling fluid. Aluminum-zinc plate and stainless steel have outstanding performance in corrosion resistance, and their service life can adapt to different environments and usage requirements;

　　2. The cooling capacity must match the applicable requirements. Because the cooling tower has a certain cooling capacity, it is not possible to save costs, and the actual cooling capacity of the selected cooling equipment cannot meet the working requirements, then this will cause the cooling to be untimely and affect safe production;

　　3. Fan selection: The fan is an important device to control the air volume of the cooling tower, but the noise effect caused by the cooling tower fan is a factor to be considered. When purchasing a cross-flow closed cooling tower, the fan should be a fan with a suitable power and a low speed. The large fan blade design ensures the air volume, so the Zhuangsu of the fan can be appropriately reduced, thereby effectively reducing the noise impact caused by the fan;

　　4. Motor purchase: The motor must have better insulation, good start-stop performance control, and stable operation. For some cooling towers, reducers are not used, so the purchase of motors must be strictly controlled. Under the condition of proper process control, the z* with high motor stages is appropriate to ensure the smooth operation of the equipment;

　　 5. The cooling capacity cannot be judged by the tower volume. Cross-flow closed cooling towers are usually designed to be more compact, because the pool is designed at the bottom. However, in order to demonstrate the cooling capacity of the cooling tower, some manufacturers have made adjustments in the design of the tower body. It is a compact equipment structure that has become larger, improved the visual perception, and created the illusion of greater cooling capacity.

　　 6. To check the relevant qualifications. Qualification is the basic thing of cooling tower quality description. Many enterprises in our country are trying to pass ISO international quality system certification. This is a manifestation of the quality of cooling towers to improve the quality of the brand.

The composition of the cross-flow closed cooling tower is relatively simple. The choice between the cross-flow cooling tower and the counter-flow cooling tower should be based on the actual space used. In terms of cooling performance at higher temperatures, the cross-flow cooling tower is better than The performance of the counter-flow type is better, but the volume of the cross-flow cooling tower will be larger and occupy more positions. The cross-flow closed cooling tower should be considered comprehensively when purchasing.

The birth of the closed cooling tower originated from the industrial evaporative cooler, which is a kind of name relative to the open cooling tower. As an indirect contact cooling tower, the filler of the ordinary open cooling tower is heated by the heat exchange plate. Tube group replacement, and the service object can be widely used from common cooling with lower requirements to high cleanliness of process fluid and high precision of process fluid temperature control.
