1. Coolant properties
The composition, concentration and pH of the coolant have an important impact on the use of the storage tank. For example, a highly corrosive coolant may accelerate the corrosion of the inner wall of the storage tank and reduce the service life of the tank. Therefore, it is necessary to select suitable corrosion-resistant materials to make the storage tank. At the same time, the concentration of the coolant will affect its freezing point and boiling point, which in turn affects the cooling effect. When using it, the coolant concentration needs to be adjusted according to the specific working environment and requirements.
2. Working temperature
The ambient temperature of the storage tank and the temperature of the coolant itself have a significant impact on its use. If the ambient temperature is too high, it may cause the coolant to evaporate more rapidly, causing the liquid level to drop too quickly, and at the same time increase the pressure of the storage tank; while the temperature is too low, the coolant may freeze and damage the storage tank and related equipment. In addition, the temperature change of the coolant during the circulation process also needs to be controlled within a certain range to ensure the normal operation of the cooling system.
3. Pressure changes
The pressure fluctuations generated during the operation of the system may affect the storage tank. Excessive pressure may cause the storage tank to deform or even rupture, so it is necessary to install a suitable pressure relief device on the storage tank, such as a safety valve, to ensure that the pressure can be released in time when the pressure exceeds the set value. At the same time, when the system starts and stops, pay attention to the smooth change of pressure to avoid water hammer phenomenon that causes impact on the storage tank.
4. Storage tank material
Storage tanks of different materials have different performance characteristics. Common stainless steel materials are high in strength and corrosion-resistant, but the cost is relatively high; plastic materials have good corrosion resistance and low cost, but the strength may not be as good as stainless steel. When choosing the material of the storage tank, it is necessary to comprehensively consider factors such as the nature of the coolant, the working environment, the service life and the cost.
5. Maintenance and care
Regular maintenance and care are essential for the normal use of the storage tank. This includes checking the tank for leakage, corrosion, deformation, etc., cleaning the impurities and sediment in the tank in time, ensuring the accuracy and reliability of instruments such as level gauges, thermometers, and pressure gauges, and replacing vulnerable parts such as seals and valves. Good maintenance can extend the service life of the storage tank and ensure the stable operation of the cooling system.
