How to ensure the quality of ?
[REVIEW] solar water heater is a family durable \"hybrid\" consumer goods, can also be labeled \"new energy appliances\", is a home appliance industry, one of four kinds of water heaters. Drop-style tank and collector are installed on the roof, wind and rain and sun, maintenance difficulties, it is more demanding in quality.
Household durable solar water heater is \"hybrid\" consumer goods, can also be labeled \"new energy appliances\", is one of the appliance industry four kinds of water heaters. Drop-style tank and collector are installed on the roof, wind and rain and sun, maintenance difficulties, it is more demanding in quality.
In each analysis of the industry\\ s own problems, how to ensure product quality is a question worth considering.
Standard: National since 1991 has been released of solar thermal standards (including the industry standard) ten, but twenty years of industrial development, and practice the standard of proof too low, and a serious lack. Useful to have on the heat according to the average heat loss of eligibility requirements and vacuum tube solar absorptance, hemispherical reflectance of the eligibility requirements, as long as the reduced collector area to maintain the original water tank capacity, Nissan 1500 coating, the exhaust off the assembly line production can be reached. This is a large number of low-end manufacturers offer cutting corners.
Detection: According to the survey, production and sales in 2000 yuan of small workshops, small businesses are almost no self-test equipment, even if only some of the majority of dress facade, national sampling Lunbu Shang, local sampling failed to fine money, and supervision and sampling the former tend to Leak, may surprise some to cope with a number or zero to do better to buy dozens of vacuum tubes coupled with the root can also be escaped.
Management: Quality Management System ISO, electrical safety, CCC, CE, environmental certification and other companies are full, but most only for publicity, the real action is in the scale of the enterprise, for small workshops, small business was virtually nonexistent. Many companies also have post with no quality control, as well as the use of false, expired certificates.
Quality: The quality of solar water heater is finished performance, life cycle, security, judged according to the standard. Useful to have the heat on the level of the same quality with a high degree of sunshine, the latitude and longitude, used to detect different errors with a large, difficult to judge, so I graded energy efficiency standards for labeling some questions. Check the water quality of the hot water is discharged two days later still meet the health standards of the water, not only rely on visual inspection, then how to use water during the guarantee?
Parts: the upper reaches of the supply of parts suppliers, small businesses tend to look at the price small workshops to see the relationship, without testing, the standard itself is still missing, especially the difference between good and bad quality of the vacuum tube is too great, and control sensor on the instrument, has been broken through the dealer and consumer users of the heart, not with the factory, the market and very messy, good or bad water quality at least one year or even three months after to repair.
Services: There is now a common problem, the factory just to sales, even if it is some of the brands they simply do everything possible to end Give a man a fish to sell, but can not delegate to fish, how to install how to maintain good service?
As a brand product is finished, water pipes, fittings, control instruments and other parts of the supply should not be difficult in these kick to the distributor. Expansion tank suction deflated customer complaints and bad, may not be the product quality problem but caused by the installation, the results of the play to end it passed to the user much dissatisfaction. Installation how to regulate? Installation requires the user to specify the correct way to use the factory has responsibility for training.
Finally a word, while the factory in the impulse, should pay attention to product quality and perfect after-sales service.
Solar Energy Industry Association, Shandong Province, the standards for to make the upgrade and standardize. Jiaxing Solar Energy Industry Association of the relevant component parts of solar water heaters, the Quality Alliance standards are being developed on the basis of the standard will soon be promulgated. This shows that our industry associations have been really in their functions, let us work together now!
