How to select closed cooling tower Part.2-- Huatal Closed Cooling Tower

When selecting a closed cooling tower, an appropriate closed cooling tower can be selected by calculating the required cooling water, cooling capacity, power and other parameters. There are many kinds of materials for the production of closed cooling towers, such as aluminum and zinc plate, stainless steel plate, glass fiber reinforced plastic and other materials.

Therefore, cost should be taken into account when purchasing. The following details introduce the skills and requirements of purchasing closed cooling towers:

1. Select according to coolant:

   Some coolants are corrosive, so the materials of the cooling tower are selected to avoid chemical reactions with the coolant. Aluminum zinc plate and stainless steel have excellent corrosion resistance and long service life, can adapt to different environment and use requirements.

2. Cooling capacity shall meet applicable requirements:

   Because all cooling towers have a certain cooling capacity, in order to save costs, the actual cooling capacity of the selected cooling equipment can not meet the requirements of the work, which will cause cooling delay and affect the safety of production.

3. The fan selection:

   The fan is an important equipment to control the air volume of the cooling tower, but the noise caused by the fan of the cooling tower is not obvious, and the sound is a factor to be considered. When purchasing closed cooling tower, the fan with appropriate power and low speed should be selected. The fan blade design is large to ensure the air volume, so it can appropriately reduce the noise of the fan, so as to effectively reduce the noise impact of the fan.

4. The motor selection:

   The motor should have good insulation performance, good start-stop performance control and stable operation. For some people the cooling tower has no reducer, so the choice of motor must be strictly controlled. In the case of proper process control, the high-order motor is the most appropriate, mainly to ensure the smooth operation of the equipment.

5. Cooling capacity cannot be judged by the volume of the tower:

   Enclosed cooling towers are usually designed to be compact because they are designed with pools at the bottom. However, in order to demonstrate the cooling capacity of the tower, some manufacturers have tweaked the design of the tower to make the equipment in the tower more compact and larger, which improves the visual effect and gives the illusion of greater cooling capacity.

6. Check relevant qualifications:

   Appraising is the most basic content in the quality specification of cooling tower. Many enterprises in our country are trying to pass the ISO international quality system certification, which is the embodiment of the quality awareness of the brand to improve the quality of cooling tower. The composition and structure of closed cooling tower are simple. The selection of cross-flow cooling tower and counterflow cooling tower should be determined according to the actual space used. In terms of cooling performance at higher temperature, the cross-flow cooling tower is better than the counterflow cooling tower, while the cross-flow cooling tower is better than the counterflow cooling tower.

7. Cover area:

   Closed cooling tower is large in volume and covers an area of more land. When purchasing closed cooling tower, it should be considered comprehensively.
