Lifting solenoid suction cups are divided into rectangular suction cup electromagnets, round suction cup electromagnets, square solenoid suction cups, etc. The application fields of suction cups are very wide. In particular, there are many industrial suction cups (such as crane suction cups) that can be applied to foundries, large steel plants, and other workpieces that are difficult for machines to grasp. Mechanical operation tools (such as electromagnetic suction cups, electromagnetic suction cups, etc.) are indispensable in the handling process.
There are also many classifications of lifting solenoid suction cups, and the cranes are widely used, also known as suction cup solenoid cranes. The production process of suction cup electromagnets is very precise. The adsorption power of different specifications is different. The average adsorption force per square centimeter can reach 10 ~ 12 kg. The adsorption surface should coincide with the adsorption surface of the suction cup. Otherwise, it will greatly reduce the efficiency of the suction cup electromagnet and reduce the adsorption power of the suction cup.
The important part of the suction cup electromagnet is mainly the development and improvement of the overall use of AN, the improvement of the leakage and waterproof performance of the suction cup electromagnet, after strengthening the waterproof function of the suction cup electromagnet on the original basis, it can be soaked for several months, not a drop of water enters, and a large number of products are put into production after the successful experiment.
The lifting solenoid suction cup is a closed magnetic circuit composed of wire sheath, yoke iron, iron core (pole column), and pole lamp. The energized conductive coil (coil/pack) generates a certain magnetic field, and the core (pole column) rearranges the irregular ferromagnetic metal atoms inside in a regular manner under the action of the external coil magnetic field, pointing in one direction, and magnetizing to increase the magnetic flux, thus generating a considerable amount of magnetic flux in the core, yoke iron and air gap.
Generally, the electromagnetic field formed by an electromagnet is related to the amount of current, the number of coils, and the ferromagnetic body in the center. When designing electromagnets, attention should be paid to the distribution of coils and the selection of ferromagnets, and the electromagnetic field should be controlled by the amount of current. Because the raw material of the coil has resistance, the size of the magnetic field that the electromagnet can generate is limited, but with the discovery and application of superconductors, there may be a chance to exceed the existing limit.
