Analysis of China's second-hand instrumentation industry development status

In the instrumentation industry, the used instrument market has risen earlier in the country, but it has been in a tepid state. What are the factors that exist? With the changes in the environment, the instrument manufacturers' distribution equipment strategy will be adjusted. What will be the market share of the used equipment market?

Second-hand equipment market rises

The United States is the country with the largest concentration of used equipment. The so-called used equipment refers to the original purchase requires the purchase of used equipment. The reason why the used equipment has a market is mainly in two aspects: the first is that the supply channels are good, and the equipment and instruments of many foreign manufacturers have deadlines, and the company also exists. Problems such as equipment renewal have led to opportunities for some people who have access to the road and business opportunities. The second is that people in China have also begun to pay attention to practicality, and the cost-effectiveness is now valued, not just a single brand. Used equipment is not a market for large pharmaceutical companies, because they are not bad money. However, it is still attractive for companies that have just started businesses.

The bottleneck in the used equipment market

The first factor in the used equipment market is that the new equipment is too expensive, and the demand of the production and R&D departments is constantly increasing. In addition, the product's own product update cycle is very slow. In order to reduce costs, production is guaranteed. From the perspective of buying used equipment is a good choice. However, the secondary market is not standardized, and the supply channels are not uniform. After-sales service can not guarantee, and to a large extent, it brings a development bottleneck to the used equipment market. As we all know, the price of each instrument is not cheap. Now we purchase instruments. Customers not only value the quality of the instrument, but also regard the quality of post-sales service and technical support. Buying an instrument requires many follow-up services. Instruments and follow-up to the instrument are an organic whole.

In recent years, many domestic used equipment has been purchased. Some of them are very successful and can be used normally in a short time. Some are not very successful in buying, equipment can not be put into use for a long time, or put into operation but low efficiency, high failure rate, long maintenance downtime. Some are even in the box. This raises a question for us. How should we buy and use second-hand equipment to operate and make decisions, so as to achieve the goals of less investment, quick results, and promotion of production development?

Second-hand equipment market domestic and imported instruments are not evenly divided

Although China's metrological instrumentation industry has achieved certain development, it is far from being able to meet the ever-growing demand for various aspects of national economic research, national defense construction, and social life. Most of China's metrology equipment products belong to medium and low-grade technology. Moreover, key indicators such as reliability and stability have not yet reached the requirements. High-end, large-scale equipment and equipment are almost entirely dependent on imports. Mid-range products and many key components and parts, and foreign companies also account for more than 60% of the domestic market. This is the status quo of domestic instruments. As for the used instruments, most users will choose to import the instruments, and the relevant data of the network second-hand network can also show this very well.

Second-hand instrument purchase dominant factors

The preparatory preparation for second-hand equipment preparation should be given the same importance as the ordering of new equipment. You can't relax your requirements because they are cheap and functional. Unlike the ordering of new equipment, its specifications and functions need to be checked according to the needs of a typical process. It is also necessary to understand and master the year of manufacture, the status of service, and the type of control system. According to Netizen's second-hand netizens in general, when buying second-hand equipment, the following issues will be considered: second-hand reasons, quality, price and after-sales. Everybody buys second-hand equipment and understands the causes of used equipment. It is an important lesson and an important reference indicator. The reasons for the use of used equipment are as follows: (1) Due to the earlier production date, the production efficiency has been Can not meet the needs of production. This kind of equipment is in service for a long time and its function and function quality are normal. (2) Idle because of factory closure or steering. This equipment has also been in service for a long time and its function and function quality have been tested. Quality is the premise, the instrument can not be used cheaply or not, quality is the last word, for the judgment of the quality of the instrument, to do a set of performance confirmation is a very good method to confirm the accuracy of the instrument there are no problems in all aspects. The price is the key factor, the price can not be too high, it should be better to have an advantage below 50 percent.

After-sales service should be the customer's most concern, the warranty contract should be more than six months, you can pay to purchase an extended warranty contract (1 year), along with maintenance equipment. If you do not provide an extended warranty contract, a second-hand equipment company professional engineer can provide on-site maintenance. Be sure to pay attention to the warranty conditions, as well as the unused or used equipment sold by the maintenance personnel themselves, that is, new and refurbished quantities. If there is a lack of maintenance documents and the warranty conditions are poor, then purchase this second-hand instrument product. For test equipment, whether the new or refurbished product is subject to inspection or the risk is greater, it must be carefully considered.

Boiler Auxiliary Equipment

Soot Blower 001 JpgBoiler auxiliary equipment mainly includes water supply equipment, ventilation equipment, fuel supply, slag removal and dust removal equipment, steam and water pipes and accessories, detection instruments and automatic control equipment.

The treated boiler feed water is lifted by the feed water pump and then sent to the upper drum through the economizer.




2. Ventilation


The ventilation equipment includes air supply fan, induced draft fan and chimney. Its function is to provide air for mule fuel combustion and lead out combustion product flue gas from the boiler, so as to ensure the normal combustion, and make the flue gas wash the heating surface at the necessary flow rate of 7a68696466fe78988e69d8331333433626465 to strengthen heat transfer. Finally, the stack with a certain height will exhaust the smoke to the atmosphere to reduce the smoke pollution and improve environmental health.



3. Fuel supply, slag removal and dust removal equipment

This is for conveying fuel to boiler, removing ash and purifying flue gas. Belt conveyor, ash conveyor, ash truck and dust remover, etc. For boilers that need to be pre processed with fuel, fuel preparation such as screening, crushing and coal grinding shall also be included. In addition, the dust remover or flue gas desulfurization and denitrification device installed in the flue at the tail of the boiler is an indispensable auxiliary equipment to reduce the smoke pollution and protect the environment.




4. Check instruments and automatic control equipment


In addition to water level gauge, pressure gauge, safety valve and other instruments installed on the boiler body, in order to supervise, regulate and control the safe and economic normal operation of the boiler equipment, a series of instruments, automatic boiler feed water regulating device, automatic fuel combustion control device, etc. are often installed. Some boiler rooms are also equipped with industrial television and remote control device and even more modern automatic control system, more Scientific supervision. Control boiler operation.


Boiler auxiliary equipment, not every boiler is equipped completely, but with the boiler capacity, type, fuel characteristics and combustion mode as well as water quality characteristics and many other factors to adapt to local conditions, adapt to the times, more practical requirements and objective conditions.
