Piano water heater electric heating tube is an important indicator of electric water heater joining

The electric heating pipe of Piano water heater is an important indicator for the joining of electric water heaters. Instantaneous electric water heaters are also known as extremely fast or fast heating or instantaneous electric water heaters. The basic feature of instantaneous electric water heaters is that cold water is superheated. When the faucet is turned on, the energy will be continuously supplied with hot water within seconds, and the faucet can be turned off when the hot water is not in use. A typical instant electric water heater is mainly composed of a heating trough plate or heating tube, a pressure sensor, a power regulator, a water volume adjustment faucet, an inlet pipe and a water outlet pipe components, among which the heating trough plate or heating tube is an instant electric water heater Vital components. The quality standards of electric heating tubes are mainly based on the main indicators such as high pressure, working leakage, reliability life, heating uniformity, etc. The product design engineers of many manufacturers do not have a comprehensive understanding of the knowledge of electric heating tubes, and the real technology of electric heating tubes The requirements and future performance are not very clear, so there are some misunderstandings about the standards of electric heating tubes. In addition, some well-known quick-heating electric water heaters in China have entered into a misunderstanding a long time ago, bringing the high standards of electric heating pipes into the industry, and some other quick-heating electric water heaters have also blindly followed the requirements of large enterprises. On the way, many domestic fast-heating electric water heaters have very high requirements for electric heating pipes. For example, the insulation resistance must reach 1000 megabytes, the high voltage must reach 2000 volts, and dry burning tests are required, which are much higher than the UL and IEC standards. The requirements for stainless steel electric heating tubes are much stricter than those in the international market. Strict requirements are right, but excessively high standard requirements do not mean that they are reasonable, because the higher the required standards, special designs, special processes, and special materials are required to complete the production of heating tubes, and the cost of materials It will be much higher. Therefore, some high standards have no practical significance, but only increase the cost. Whether the instant electric water heater product using stainless steel electric heating body can be made well depends on the manufacturing level and design level of the enterprise in the end. Good product design is very important to product quality and manufacturing cost. Electric heating body is an important key component in instant electric water heaters. If the heating body is not done well, the quality of the product will be very unreliable. . Although the stainless steel electric heating element is a relatively mature technology, the material of stainless steel has its particularity and the welding process is also more complicated. Therefore, when designing the structure of the heating element, pay special attention to the internal stress caused by the uneven heat transfer of the stainless steel. , The focus is to do some special flexible designs in this area, and at the same time, relevant tests must be done to verify the reliability of this design, so as to ensure the product's use effect and give full play to the advantages of stainless steel heating tubes. For manufacturers of instant electric water heaters, if the company itself is not strong in product structure design, it is safer to use copper heating pipes. In theory, the cost of using stainless steel electric heating tubes is lower than that of copper heating tubes, but if the product is reversed, the cost of stainless steel will be higher. (
