Control Standards and Operation Precautions of Closed Type Cooling Tower Water Temperature

Control Standards and Operation Precautions of Closed Type Cooling Tower Water Temperature

The closed type cooling tower is a kind of circulating heat dissipation equipment, which can absorb the heat generated by circulating water or enter the closed type cooling tower into the closed type cooling tower, and then spray it on all the materials and contact with some large machines After that, all the heat can be dissipated into the air, so as to better reduce the circulating water temperature of the closed type cooling tower. Through these closed type cooling towers and the related mixed contact, all the temperature differences can be used to reduce the temperature. The water evaporates into the air, so that it can achieve the effect of self-cooling.


1. Control standard for the outlet water temperature of the closed type cooling tower


In the actual temperature control process of the closed loop cross flow cooling tower, there will be more control standards, and the temperature difference between the inlet and outlet water of the cooling tower will also be different. This is also the most effective way to measure, and also has More important parameters, in general, cooling towers will have various designs. The temperature of the closed type cooling tower is basically around 37 °C, the temperature of the outlet water is around 32 °C, and the difference in water temperature is around 5 °C. The design conditions of industrial closed type cooling towers are basically divided into many different designs, which can be divided into several grades, so that in the process of design, the difference in water temperature is 8 ℃ to 20 ℃.


During the actual operation of the closed type cooling tower, it is necessary to ensure the smooth flow of all links, and some blockages cannot occur. The most common blockage of the oil pipeline or the blockage of scale, if there is a blockage, it is best to be able to first time to clean up, so as to ensure the final cooling effect, and in actual use, there must be more sophisticated use.


2. Precautions for the operation of the closed type cooling tower


In the actual application of the closed type cooling tower, there will be more precautions. The reducer should always check the position of the entire oil mark, and the lubricating oil must be recommended to have various hyperbolic cooling tower gearbox oil. For industrial oil, use some oil with relatively high viscosity in summer. When running for the first time, be sure to check the operating standard. If it is more than 20 days later, be sure to drain all the oil in it. Empty, put in new oil.


When the closed type cooling tower is in actual operation, there will be more fans or reducers and other operating standards. Before operation, check according to the relevant instructions, especially the wiring of some motors. In the actual wiring selection At the same time, there will be various options, and sometimes all aspects are inconsistent, especially easy to cause wiring errors, and then start after meeting the requirements, the starting sequence is different, from low-speed to high-speed blades The angle will also be installed according to the relevant specified values. If high-speed operation is required, it may exceed the original rated value to some extent.
