How is the heating tube of the rice steamer connected?
This article delves into how the heating tube of a rice steamer is wired. The commonly used heating tube nozzle of a rice steamer is a double U-shaped heating tube, with a national standard power of 2KW, 3KW, and 4KW. The commonly used diameter is 12mm stainless steel tube, and the cheapest material is stainless steel 201. The disadvantage is that it is easy to damage. 304 and copper heating tubes have a better service life. If you want the heating tube of a rice steamer to be used for a long time, it is recommended to use dry burning for the first time, Secondly, if the heating length of the heating tube is increased without length limitation, the pipe material should be at least stainless steel 304!
Let's take a look at how the specific stainless steel heating tube is wired?
1. Firstly, when purchasing heating tubes, we need to distinguish the rated voltage of a single heating tube. If the rated voltage of a single heating tube is 220V and the total power supply is 380V, we will connect three heating tubes in a group using a star shaped connection method, as shown in the following example
2. If the rated voltage of a single cable is 380V and the total power supply is 380V, we will connect three heating tubes in a group using a triangular connection method, as shown in the example below
It is particularly important to note that if the wrong wire is connected, the success rate may increase exponentially, leading to damage to the U-shaped electric heating tube or reducing power, resulting in prolonged heating time! If a single 220V is connected according to the 380V connection method, for example, if the power of a single 2KW suddenly increases to nearly 6KW, the heating tube will quickly burn out; On the contrary, if a single 380V electric heating tube is connected using a 220V single method, the actual power of a single 2KW heating tube is only about 670W, which will greatly prolong the heating time!
