There are many sayings about the Stainless steel immersion heater wiring, and it is very important to heat the optical wiring. We must pay attention to the wiring when it is wired. Otherwise, some faults will occur. Please let us know how the Industrial electric immersion heater is wired.
Wiring method of Industrial immersion heater:
The first one is: a 3 phase flange immersion heater with a rated voltage of 220V, which is connected to a 380V circuit, requires a star connection.
The second type is: a Explosion proof immersion heater with a rated voltage of 380V, which is connected to a 380V circuit, requires a delta connection.
If the Explosion proof oil immersion heater is rated voltage 380V, the star connection method is adopted, the rated power of the screw plug immersion heater is not reached. The actual power is (220*220)/(380*380) of the original rated power. About one-third.
The heating of the Flanged Immersion Heater mainly relies on the internal heating wire to generate heat through the current, and the wiring mode determines the current and voltage state of the energization, so the wiring mode of the 220V 10KW industrial immersion heater is very important. The influence of the wiring method on the Brass Flange Immersion Water Heater can be understood by the article on the influence of the electric heating pipe wiring. Under reasonable conditions of use, the higher the voltage and power of the Flange Type Immersion Heater, the higher the heat efficiency. The Stainless Steel 304 Flange Immersion Heater wiring method determines the way that the external voltage and current pass through the resistance wire, so the choice of the wiring mode of the Industrial Dryer Immersion Heater has important practical significance. So how do we choose the wiring method of the Explosion proof immersion Tank heater?
There are two types of SUS304 220V 380V 3KW 6KW 9KW Immersion Heater commonly used on heating pipes: delta connection and star connection (also known as Y-connection).
1, the triangle connection method:
1 delta connection: the first end of each component of the heating tube is connected to the tail end of the other component, and the three contacts are connected to the three phase lines respectively;
2The characteristics of the delta connection: The three electric heating tube components are rated at 380 volts; if the resistance values of the three components are different, the feasibility of this connection is not affected. The delta connection is three times more powerful and current than the star connection.
2, star connection method:
1 star connection method: heating elements of three electric heating tubes, the first ends of each element are connected together (this point is called neutral point), and the three tail ends are connected by three phase lines respectively.
2 When the three components are rated at 220 volts; if the resistance values of the three components are different, the neutral point should be connected to the neutral line.
In our lives, we can't do without the application of Industrial Submersible Water Oil Heater. So what are the precautions about 3KW Stainless Steel Immersion Heater Element? Do you understand? Let's take a look at it below.
1. 2 Inch Stainless Steel 304 Flange Immersion Heater is allowed to work under the following conditions: A. The relative humidity of air is not more than 95%, and there is no explosive and corrosive gas. B. The rated working voltage should not exceed 1.1 times of the outer casing and should be effectively grounded. C. Insulation resistance ≥ 1MΩ Electric strength: 2KV / 1 minute.
2. The Brass Screw Plug Industry Electric Immersion Heaters should be positioned and fixed. The effective heating zone must be completely immersed in liquid or solid metal. Air combustion is prohibited. When the surface of the Brass Flange Industrial Electric Immersion Heaters is found to be scaled or carbonized, it should be cleaned in time to avoid heat and shorten the life of the impact.
3, hot fusible metal or solid nitrate, alkali, asphalt, paraffin, etc., should reduce the use of voltage, the medium to be melted to rise to the rated voltage.
