The wire of the electric heater must be installed with a plug, and the wire head of the electric heater cannot be directly inserted into the socket; the aging or damaged circuit should be replaced in

The resistance wire that has been repaired many times should not be used anymore, and a new resistance wire should be replaced; all kinds of flammable and explosive items are strictly prohibited to be

Wipe the surface of the electric heating tube first, then turn on the AC 220V power supply, dry it in the air, and turn off the power after the surface turns red. After the electric heating tube is co

The factors that affect the electrical strength of the electric heating tube mainly include the thickness of the insulating layer, the quality of the raw material of the insulating layer, the length o

The form of infrared heat transfer is radiation heat transfer, which transfers energy by electromagnetic waves. When far-infrared rays hit the heated object, part of the rays are reflected back, and p

It is mainly related to the quality of the resistance wire and the technological level of the manufacturer. Before mass production, Xinhongda electric heating needs to do a temperature coefficient tes

Electromagnetic heating is to generate an alternating magnetic field through the components of the electronic circuit board. When a ferrous container is placed on it, the surface of the container is c

Corrosion resistance is a problem often encountered by water heating electric heating pipes and barbecue electric heating pipes. In addition to the reasonable selection of materials, it is also relate

(1) It is non-conductive, will not burn and explode, and has no chemical corrosion and pollution, so it is safe and reliable to use. (2) The heating and cooling speed is fast, and the work efficiency

1. The red marked parts of the size of the liquid heater in the outline dimension drawing must be fully immersed in oil to avoid burning the components. The heated oil should be non-corrosive. 2. The

Power = root 3 times current times voltage, so current equals, power divided by (root 3 times current), single phase heater formula, power equals current times voltage.

The components should be stored in a dry place. If the insulation resistance drops to less than 1 megohm due to long-term storage, it can be dried in an oven at about 200℃ for several hours (or the lo
