Electromagnetic pump without mechanical moving parts, simple structure, good sealing, reliable operation, does not require shaft sealing, so in the chemical industry, the printing industry for the transport of some toxic heavy metals such as mercury, lead, for the transmission of nuclear power plant Liquid metal (sodium or potassium, sodium-potassium alloy) as a heating medium is also used for transporting molten non-ferrous metals in casting production. Flow up to 13,000 m 3 / h, pressure up to 1.7 MPa and temperature up to 1200 ° C. Electromagnetic pump according to the form of power can be divided into AC pump and DC pump. AC electromagnetic pump according to the liquid metal current feed can be divided into conductive (conductive) electromagnetic pump and induction electromagnetic pump. Conductive electromagnetic pump with DC or AC. It has a tube made of a non-magnetic refractory metal (see photo), surrounded by a magnet, with the lines of magnetic force perpendicular to the tube. When passing the current perpendicular to both the tube and flux lines, a mechanical force is generated to push the conducting fluid out of the tube according to the left-hand rule. The conductivity type is generally a small pump for low pressure and small flow. Conductive electromagnetic pump, the current from the external power supply through the pump on both sides of the electrode directly to the liquid metal. Induction pump, inductive use of multi-phase AC. Current is induced by alternating magnetic fields. The latest type of induction electromagnetic pump is a linear induction pump, equipped with a flat, linear stator windings, inductive axial force, large size, large flow pumps are of this type. According to the structure of different electromagnetic pumps can be divided into plane pumps and cylinder pumps. The use of magnetic field and current in the conductive fluid interaction, the fluid by the electromagnetic force generated pressure gradient, thereby promoting fluid movement of a device. Mostly used for pumping liquid metal, so called liquid metal electromagnetic pump. Electromagnetic pump according to the form of power can be divided into AC pump and DC pump; by liquid metal current feed can be divided into conductive electromagnetic pump and induction electromagnetic pump; according to the structure can be divided into flat pump and cylinder pump. Conduction pump, the current from the external power supply through the pump electrode on both sides of the electrode directly to the liquid metal; induction pump, the current induction by the alternating magnetic field generated. Electromagnetic pump without rotating parts, simple structure, good sealing, reliable operation, so in the chemical industry, the printing industry for the transport of some toxic heavy metals, such as mercury, lead, etc .; in the atomic power industry for the delivery of a particularly lively chemical properties Metals, such as sodium, potassium and sodium-potassium alloys, can be used as a quantitative pump for active metals such as aluminum and magnesium in casting companies, but are now mainly used by large enterprises such as the military. The disadvantage of electromagnetic pump electromagnetic pump structure is less efficient, in the smelting, casting industry has not yet been widely used. Electromagnetic pump similar to the ordinary solenoid valve, which uses AC power as the work force, the current through the electromagnetic windings to form an alternating fixed magnetic field, and the formation of the pump body can interact to drive the pump body vibration, promote liquid output.
LED Linear Tube
The led tube is rgb color dmx lighting, can be used as Xtube, mediatube, outdoor tube for creative lighting solutions, such as make a 3D cube. led tube color have rgb color tube, rgbw color tube. Regarding how to program led light, because the light is dmx programming, so ISEELED dmx LED Controller or Artnet Controller are suggested. ISEELED DMX512 led linear tube compete with eurolite led tube, osram led tube, Philips led tube, american dj led tube. The pixel tube have 1led 1pixel, 2led 1pixel, 3led 1pixel, 6led 1pixel. Address setting have two type, one is auto address, another is manual address. That's to say we have led tube auto and led tube manual. Auto led linear tube, you don't need assign dmx address, it's convenience for event show and led light rental. Manual led linear tube, you need assign dmx address by address writer before light up, for DJ club, architecture light, it's ok.
