Recently, many cities and provinces have experienced the storm hit. Lodging in the heavy rain not only crops, there are many "fragile" and
Solar water heaters Some support seriously distorted, hanging in the roof, crumbling; some were strong winds with the "root" uprooted, thrown to the ground. Many have installed solar energy
Water heater Roof in ruins. Should be said that urgent is the fact that wind and rain, but after the storms, most of a good brand or safe, normal use, and some no-name products are vulnerable, the situation is particularly acute in rural areas. It is understood that the main reason not stand the test of wind and rain some solar water heater stand of "body bone" However hard, innate, "calcium", and in the installation problems, which led to his "fragile", mainly:
One scaffold with low quality standards. In accordance with recommended industry standards, supports up with a plate should be at least 1.5mm thick, 100mm wide and be considered qualified, and some solar water heater manufacturers have cut corners in order to reduce costs, support timber becomes narrow and thin, only 1 ~ 1.2 mm thick, 60 ~ 70mm wide; there are many dig hole plate bracket, the industry as "material saving hole", thereby greatly reducing the torsional capacity of wind resistance. Once hit by stormy weather, they stand as suffering from "rickets", it is easy to "material saving hole" fracture took place. Some stents are used in aluminum alloy, shown in the storm obviously very poor wind resistance, some of the stents have been blown out of shape.
Second, poor corrosion resistance of material support, or corrosion protection is not complete. Exposed long solar water heater, frame must be treated with preservatives in order to ensure safety, however, some support materials used, technology is not up to spray layer and the substrate lead to poor adhesion, easy to fall off of aging, long-term commitment, windy weather, stand easy corrosion fracture in office.
3, installation design, unreasonable and not standard installation, professional, or even cut corners. Many windblown style support structure is unreasonable, inconsistent with basic principles of structural mechanics, lack of necessary support and connectivity components. Some poor installation techniques, there is no effective fixed, but simply "release" on the roof. Some very small water heater stand with a twisted wire even if "everything is all right" not to regulate the installation of the test is difficult to withstand wind and rain.
For solar water heaters installed on the "cartilage" issue, solar water heaters in the countryside of the entire industry after the active trading at a macro level, China
Consumers Association Remind consumers, in the purchase of solar water heater when note the following:
1, in the purchase of solar water heater, be sure to look at whether it is the professional installation technician, installation design is scientific, installation
Service Whether the specification. The installation of quality solar water heater solar water heater is directly related to the use and safety. At present, solar water heater industry-wide "re-
Sell Not re-install the "phenomenon, many businesses do not establish a professional installation team, the installer did not undergo a rigorous training, and even some grocery stores in rural areas have also assumed the agent-name solar water heater sales and installation of dual responsibility, such "service" either in the installation of the design of scientific rationality, or installation professional, the installation can not guarantee the quality.
Second, we must attach importance to support the selection, processing, generous degree of quality of the material status of installation. At present, no install solar water heaters mandatory national standards, such as installation support material selection, strength is not mandatory. If these poor installation material selection, process tests, the anti-aging, anti-twist and wind resistance will be poor, it is inevitable because of "calcium" and suffering "rickets", which would leave the use of solar water heaters serious security risks.
Third, select the installation service as a fairly standard well-known brands. At present, the solar water heater industry was mixed good and bad, in the installed services not currently introduce mandatory national standards, many enterprises install quality and service not paid enough attention, but relatively speaking, some of the installation of responsible business development of strict standards , regulate more, after-sales service, relatively perfect, therefore, choose to buy solar water heaters a good reputation, quality installation and reliable after-sales service are undoubtedly the best way to protect the brand.
