Electromagnetic pump is a kind of equipment without mechanical moving parts. It has the characteristics of reliable operation, good sealing, simple structure and no need of shaft sealing. These advantages make it very important in the printing, chemical and other industries It can deliver some toxic metals. In the electromagnetic pump often need to work when the motor, that many people will put forward the "why the electromagnetic pump motor" this question. Why the electromagnetic pump motor with liquid metal in the current feed can be divided into 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, 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. In the magnetic field in the fluid under the action of electromagnetic force in a certain direction of flow of the pump. 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 electromagnetic pump means that the pump impeller and motor drive connection between the use of electromagnetic clutch, the drive or the need for the motor. With the increasing transport volume of toxic metals and metals, such as mercury, lead, potassium-sodium alloy and non-ferrous metals in modern industry, the demand for electromagnetic pumps is also increasing. Meanwhile, the demand for electromagnetic pumps is also raised Requirements, I believe for the electromagnetic pump research and development will continue.
Speed Control Peristaltic Pump provides flow range from 0.00011 to 6000 mL/min with variable pump heads and tubings. It provides not only the basic functions such as reversible direction, start/stop and adjustable speed, but also Time Dispense Mode and Anti-Drip function. With MODBUS RS485 interface, pump is easy to communicate with external device, such as PC, HMI or PLC.
