Today to introduce steel concrete structure cooling tower maintenance methods.
1. For the evaporator of the air cooler: always check the defrosting situation. Whether the defrosting is timely and effective will affect the cooling effect and cause the liquid return of the refrigeration system.
2. Always observe the operating status of the compressor and check its exhaust temperature. When changing seasons, pay special attention to the operating status of the system, adjust the liquid supply and condensation temperature of the system in time, and pay special attention when adjusting, otherwise it is particularly prone to problems.
3. Listen carefully to the running sound of the compressor, cooling tower, water pump or condenser fan, and deal with any abnormalities in time. At the same time, check the vibration of the compressor, exhaust pipe and anchor.
4. Maintenance of the compressor: The internal cleanliness of the initial system is poor. After 30 days of operation, the frozen oil and dry filter should be replaced once, and then replaced after half a year of operation (depending on the actual situation). For the system with high cleanliness cooling tower, the frozen oil and dry filter should be replaced after half a year of operation, depending on the situation.
In recent years, frequent accidents of cooling tower fire, which reminds us that we should pay attention to the prevention of FRP cooling tower fire. We should pay attention to several aspects: including tower analysis of the cause of the fire, education and study of work sign, safety management, fire prevention measures, etc. Let's learn about it together with Xiaobian.
Analysis of the causes of fire in (I) FRP cooling towers.
1. Polypropylene corrugated sheet easy to burn.
From the structural point of view, the shell of FRP cooling tower uses unsaturated polyester as adhesive. Glass cloth is made of reinforced material. The packing in the tower is modified PVC corrugated sheet or polypropylene corrugated sheet, which is easy to burn in case of fire, which is the main cause of fire accident..
2. Safety education is not enough before construction, and workers work blindly.
Because the filler is flammable, electric welding is strictly prohibited at the installation site of the cooling tower. At the same time, the use of FRP cooling towers, there should be standing arson measures. However, before the installation and construction of the factory, this note was not paid enough attention to the fire hazard of the cooling tower, and there was also a lack of understanding of the fire hazard of the cooling tower, which led to the blind operation of the workers, which was also an important cause of the accident.
3. There is a gap in safety management and there are rules that do not follow.
Before installation and construction, if the fire permit is handled in accordance with the fire management regulations, it may not cause losses. However, people do not know enough about the importance of handling the fire permit, and it is also one of the reasons for the accident..
4. The fire prevention measures are not perfect.
Fire-fighting facilities are too far away from the scene, delaying the timing of fire-fighting in the event of a fire..
(II) precautions against fire in FRP cooling towers.
Be familiar with the characteristics of equipment or products, conduct safety education before construction, and prevent illegal hot work and unlicensed hot work. Try not to fire near the cooling tower, and take effective safety measures when the cooling tower is hot. The tower shell can be covered with a wet sack. Tower mouth and tower packing, so that the splash of sparks when wet extinguished. Fire scene also equipped with fire extinguishers. Manufacturers should improve the fire performance of FRP cooling towers..
In the process of cooling tower work, sometimes there will be the problem of circulating water temperature rise when the machine is running, and it is in the case of machine operation, so what is the reason for this.
Today, we analyze the problem of water temperature rise in the process of using the cooling tower, so that users can find and solve the problem in time, and will not affect the production.
Analyze the cause and solve the problem.
1: There is too much circulating water in the cooling tower, which exceeds the amount of circulating water that the cooling tower can withstand. At this time, we have to adjust the water volume to the cooling tower design standard.
2: The air volume is uneven, then we need to improve the ventilation environment.
3: air inlet network blockage, clear such as tuyere network blockage.
