1. The conductor in the magnetic field, through the current, the conductor will be subjected to the thrust of the magnetic field, the three directions perpendicular to each other, the size of the thrust F = I × B × L. Conducted boiler feed pump without any rotating parts, to solve the mechanical pump wear problems, the formation of maintenance-free welder. However, due to the liquid metal contact with the large current electrode to the liquid metal conduction current process, due to the oxide residue on the electrode attachment and shielding, resulting in wave instability, and even ups and downs, can not be stable, the domestic imports of Switzerland such models Nearly 50 basic have been disabled.

2 induction boiler feed pump principle It uses the principle is the use of single-phase C-type opening electromagnet, due to the difference between the inner and outer ring and the inner and outer ring magnetic field phase difference, and thus the formation of forward magnetic field component, from the leading phase point lagging phase Of the forward magnetic field component. The liquid metal brazing filler metal in the forward magnetic field component cuts the flux lines and is therefore subjected to a forward force to pump the liquid metal brazing material. Due to the use of magnetic phase difference generated phase difference, the formation of the forward magnetic field component, the forward magnetic field component is very limited, most of the pulsation magnetic field does not produce forward thrust to produce as shown in Figure broad-wave peak (300mm ~ 400mm peak width) and Very high peak (40mm height) is very difficult.

What is the principle of the boiler feed pump?

3. The principle of three-phase asynchronous induction pump This is another patented technology obtained in China in wave soldering machine, which not only solves the conduction peak of the conduction current electrode of the conduction type boiler feed water pump of the conduction type boiler feed pump, Stable problems, without any rotating parts, no current transformer, maintenance-free, wear-free, and high efficiency, access to high and powerful peaks and wide peaks. Three-phase asynchronous induction pump principle is the use of three-phase power 120 ° phase difference between each other in space, forming their own magnetic field, the magnetic field synthesis is a forward magnetic field cutting magnetic lines, the induction current, the formation of forward electromagnetic force. Principle and Instruction: Boiler feed pump working principle and application example Boiler feed pump is a kind of electromagnet driven high pressure micro-pump. Its features: compact structure, output pressure, no leakage, small size, good dynamic regulation, etc. 1. Working principle : When the boiler feed pump coil power, the slider in the electromagnetic field force to the right, the sealed chamber volume increases, the pressure is less than the inlet pressure, the liquid flows into the sealed chamber when the boiler feed pump power, the slider in the spring The force moves to the left, the sealed chamber volume decreases, the pressure is greater than the outlet pressure, the fluid flows out from the outlet after the power rectification pulse frequency of 50Hz or 60Hz, slider around the frequency of 50Hz or 60Hz, so fluid Continuous flow from the import and export. 2. Boiler feed pump is mainly used for beverage brewing machines, steam cleaners, red teeth, spray humidifier, filter pressurization, carpet cleaning machines and so on.
