In real life, we come into contact with electromagnets in many daily necessities, electrical appliances, and other things. However, the primary application of electromagnets is still in industry. In theory, electromagnet manufacturers are quite familiar with the principles of electromagnets. But they often encounter users asking: How to use an electromagnetic suction cup and what points should be emphasized when using it? Based on this, electromagnet manufacturers will put forward several points to be noted for the use of electromagnetic suction cups, hoping to help most of the peers in need.
Before lifting and operating, you should first check the surface cleanliness of the workpiece to be lifted. Try to deal with it before lifting so that rust and protrusions can be found and cleaned up before the object is lifted. At the same time, pay attention to ensuring that the center - line rod of the electromagnetic suction cup and the center of gravity of the workpiece are in the same position. Also, check whether the safety wedge of the handle is automatically locked, and then carry out the lifting operation.
Pay attention to the shape of different workpieces and flexibly use a variety of different lifting methods. The use of good methods can reduce mechanical wear and cost. When lifting a cylindrical workpiece, keep the contact between the B - shaped groove and the workpiece as two - straight - line contact. Therefore, the lifting force of the electromagnetic suction cup is only 30% - 50% of the rated lifting force.
Pay attention to the change of the ambient temperature of the lifting itself and the movement of the surrounding people. Overloading and people passing through are prohibited.
