Reasonable selection of heating equipment components can effectively reduce production costs, and reasonable use of heating equipment components can increase the life of the components. The electric heating tube is one of the heating elements. It has many advantages such as environmental protection, energy saving, safety, simple operation, and low price. The electric heating tube heating is one of the most ideal elements for the electric heating element. It can be used one day earlier, and the benefit will be the same day earlier. The manufacturer teaches you how to choose electric heating elements, hoping to give users a most useful reference:
The heating of the electric heating tube is mainly caused by the internal heating wire through the electric current, and its application is mainly used for heating water, heating oil and other liquids. It can be said that the electric heating tube is the most widely used electric heater element. Common electric heating pipes are made of steel pipes, copper pipes, stainless steel pipes, and titanium pipes. There is no standard model for electric heating tubes, and they are usually customized according to customer requirements. The voltage is normally 110V-380V, and the power is 0.1KW-100KW.
In the use of electric heating tubes, the wiring method of the electric heating tube determines the current and voltage state of the energization, so the wiring method of the electric heating tube is very important, and it is necessary to talk about it.
Under reasonable conditions of use, the higher the voltage and power, the higher the heating efficiency of the electric heating tube. The wiring method of the electric heating tube determines the way the external voltage and current pass through the resistance wire, so the choice of the wiring method of the electric heating tube has very important practical significance. The two most used delta connection and star connection (also commonly known as Y connection)
1. Delta connection: ①Delta connection: The first end of each element of the electric heating tube is connected to the end of another element, and the three contacts are connected to three phase wires respectively; ②The characteristics of the delta connection: three electric The rated voltage of the heating tube element is 380 volts; if the resistance values of the three elements are different, it does not affect the feasibility of this connection. The power and current of the delta connection are three times that of the star connection.
2. Star connection: ①Star connection: the heating elements of three electric heating tubes, the head of each element is connected together (this point is called the neutral point), and the three tail ends are respectively connected to the wiring of the three phase wires Way. ②When the rated voltage of the three elements is 220V; if the resistance values of the three elements are different, the neutral point should be connected to the neutral line.
