In the process of contact with customers, customers are often confused about the price of drying equipment. Take the tube dryer as an example. The same model of tube dryer, whether it is quoted by weight or quoted by heat exchange area, Manufacturers' quotes vary widely. Customers often ask: How is the price gap so much the same as a tube dryer?
In fact, this problem is very simple, but the user's understanding of the tube dryer is still inferior to the manufacturer, plus many customers are completely price-oriented, so the above problems have arisen. There are several reasons for analyzing these issues:
1 The content of the quote is different
In general, the host of the tube dryer should include the main motor, main drive, fluid coupling, rotary joints, and the like. The basic supporting equipment includes induced draft fans, pipes, dust collectors, shutoff fans, fans, feed spirals, discharge spirals, etc. If it is a material that needs backmixing, it should at least include mixing spirals.
Some manufacturers' quotes are only mainframes, and some manufacturers include ancillary equipment. Of course, the included equipment will also be different. Therefore, when customers ask for quotes, they must be clear about what the manufacturer says about the bundled dryer.
2 Different materials and manufacturers
Tubesheets, heads, and tube bundles of tube dryers are all important components. Therefore, the materials and manufacturers used determine the equipment's price, performance, and service life.
In particular, the tube bundle must be a high-quality boiler steel pipe, and it is the implementation of the national standard 3087 standard. In addition, the manufacturer of the pipe should also pay attention to, for example, a pipe produced by a company in Tianjin, although the price is cheap, but the service life is very short (about less than a year), if the user buys a pipe dryer, the pipe is used, although The price is cheap, but it will be bad after use.
Therefore, when purchasing a tube dryer, it is important to understand the materials and manufacturers of these important components, and of course, also important indicators such as thickness. It should be known that some manufacturers use cutting-edge methods to reduce costs.
3 different processing technology
This problem is difficult to make clear here. Usually, the processing technology is complex and the performance of the equipment will be good. For example, the two ends of the tube bundle must be turned as a whole, otherwise the coaxiality cannot be guaranteed.
In fact, equipment processing is good or bad, mainly the processing of some details. For example, the flange of the head is not easy to handle and it is easy to leak. Some manufacturers have adopted welding methods to make this place a life-order product. The price is indeed cheap, but once a problem occurs, the entire equipment becomes obsolete. The well-manufactured flanges can be disassembled and the seals are also very good, but this requires complex and careful processing, of course, the price will be higher. However, this is a simple place that ordinary users can't notice.
It should be noted that, not necessarily a large manufacturer's product processing process is good, tube dryer processing process is complex, the need for some large-scale processing equipment, small manufacturers generally use external processing methods, some large manufacturers can own processing, and some instead took The simple method, the quality of this processing is not as good as a small manufacturer.
4 Attention to refurbished equipment
Some tube dryers that are very cheap are used equipment refurbished, but it is difficult for ordinary users to understand it clearly. Therefore, be sure to look at the purchase.
