Precautions When using cross flow square cooling tower:
1. Antifreeze in winter
In order to prevent the cooling liquid from freezing and causing the water tank to burst and crack after stopping use in winter, it is required that the freezing point of the cooling liquid should be about 10°C lower than the lowest temperature in the area to prepare for sudden changes in the weather.
2. Anti-corrosion
The radiator, water pump, cylinder block, cylinder head, water distribution pipe and other components in the cooling system are composed of steel, cast iron, brass, copper, aluminum, solder and other metals. Due to the different electrode potentials of different metals, the role of electrolyte in the At the same time, the acidic products formed by the decomposition of glycol substances in the cooling liquid and the acidic waste gas after the combustion of the fuel may also penetrate into the cooling system and promote the corrosion of the cooling system. Corrosion of the cooling system will cause failure of the lower chamber of the radiator water tank, fuel injector spacer, cooling pipes, joints and water tank pipes, and at the same time the corrosion product Dusset pipe will cause the engine to overheat or even paralyze; if the corrosion is perforated, the coolant will seep into the combustion Chambers or crankcases can cause serious damage because when the coolant or water mixes with the oil, grease and gums are created that impair lubrication and cause valves, hydraulic valve push rods and piston rings to bond. Therefore, a certain amount of anti-corrosion additives are added to the coolant to prevent corrosion of the cooling system.
3. Anti-scale
In the circulation of the coolant, the generation of scale should be reduced as little as possible, so as not to block the circulation pipes and affect the heat dissipation function of the cooling system. To sum up, you should be careful when selecting and adding coolant. First of all, you should choose the appropriate ratio of coolant according to the specific situation. Next, add coolant. Add the coolant with the selected ratio to the water tank to make the liquid level reach the specified position.
Application of 300T Cross Flow Square Cooling Tower
The process of cooling water in a cooling tower is a heat and mass transfer process. The cooled water is distributed to the inner packing of the cooling tower by a nozzle, a water distributor or a water distribution plate, which greatly increases the contact area between the water and the air. Air is circulated by the induced effect of fans, forced air, natural wind or jets.
Cooling towers are mainly used in air-conditioning cooling systems, refrigeration series, injection molding, tanning, foaming, power generation, steam turbines, aluminum profile processing, air compressors, industrial water cooling and other fields. . The specific division is as follows:
A. Air temperature regulation categories: air conditioning equipment, cold storage, cold storage room, freezer, heating and cooling air conditioning, etc.;
B. Manufacturing and processing categories: food industry, pharmaceutical industry, metal casting, plastic industry, rubber industry, textile industry, steel mill, chemical industry, petrochemical products, etc.;
C. Mechanical operation and cooling: generators, steam turbines, air compressors, oil compressors, engines, etc.;
D. Other industries.
