Many users are worried about delivery time, quality of goods, installation, debugging and acceptance, after-sales and other issues from the time they order equipment. This is human nature. Large equipment orders require high advance payments. Once quality problems occur in the goods, it is not only troublesome, but also the relevant managers need to bear considerable responsibilities. Therefore, the selection of closed cooling tower manufacturers, model selection, process control, installation and commissioning, and acceptance all need to be carried out professionally, rigorously, and standardizedly. Among them, product debugging and acceptance are the most important. 1. Appearance quality Appearance quality represents the basic quality status of a closed cooling tower manufacturer. Of course, shoddy manufacturing is not acceptable. The basic surface quality, welds, screw holes, flat surfaces, etc. must be standardized, otherwise it can be judged as unqualified. 2. Material acceptance: It is very important to check whether the material of the goods supplied by the closed cooling tower manufacturer meets the requirements. For example, the required 304 stainless steel, whether it is 304, the galvanized plate requires Z700, whether the coating thickness meets the standard, and whether the steel plate thickness tolerance is normal. There are professional acceptance methods for these, and we must not be careless. 3. Model parameters The product model parameters mainly refer to the main dimensions of the closed cooling tower and the specifications of important components. For example, whether the size of the closed cooling tower fan, the size of the closed cooling tower motor, the size of the spray pump, etc. are consistent with the ordered product requirements. 4. Commissioning and acceptance of retractable cooling towers is a very important step. Whether the product is running smoothly, whether the system design is reasonable, whether the basic energy consumption meets the standards, the degree of motor heating, whether the valves are tight, whether the flanges are leaking, etc. all need to be carefully and strictly inspected. 5. Performance acceptance Performance acceptance is the most problematic aspect of a closed cooling tower. Generally, project progress is highly variable, and the working conditions during the acceptance season are likely to be different from the design conditions. For example, during winter acceptance, the ambient temperature is low. When users perform performance acceptance, the performance of the closed cooling tower is very good. However, this performance result is likely to be based on the illusion of low ambient temperature. Once the second summer arrives, the performance may not be up to standard. There are two ways to deal with this situation: First, the most direct, winter debugging will be carried out first, and both parties agree that the real performance acceptance will be carried out in the following summer. ； Second, according to the theoretical formula of performance conversion, conversion of different working conditions can be achieved, so that accurate results can be obtained. However, most manufacturers do not have this method, not to mention that the users are not professionals in the closed cooling tower industry, so only manufacturers with standardized and technical background can do it. No matter what, equipment acceptance is only the final step. If you treat it seriously, rigorously and professionally from before ordering, there will be much less trouble later.
