Information

An electromagnetic sucker is used to lift a sling of a magnetically conductive ferrous metal material and its articles. The electromagnetic sucker is composed of a cast steel shell and a coil placed therein (see FIG. 6-5). Direct current is fed into the coil winding by a cable.

When the lifting electromagnetic suction cup lands on the black metal product being hoisted, the magnetic flux of the electromagnet is closed by the outer shell of the electromagnet through the object, generating electromagnetic attraction (see figure 6-6) and remaining until the power is cut off. In order to ensure safety, electromagnetic sucker lines have delay performance.

Round electromagnetic sucker is used for lifting ingot, iron and steel casting and scrap. Rectangular electric disks are used to lift steel plates, steel tubes and various sections. The advantage of electromagnetic sucker is automatic loading and unloading, high efficiency. Disadvantage is from the major, large consumption of power, power will fall when the item. Hoisting capacity is affected by temperature and Mn and Ni content. General lifting temperature in the black metal products below 200℃, the temperature of 500℃ when the lifting capacity of the electromagnetic sucker will be reduced by about 50%. When the temperature reaches 700℃, there is no lifting capacity (general carbon steel to 785℃ magnetic all disappeared). At present, there are also used for high temperature lifting electromagnetic suckers, this electromagnetic suckers can absorb high temperature products, but ordinary electromagnetic suckers are not allowed to absorb high temperature products.
 
Operation safety requirements:
 
(1) pay attention to balance, electromagnetic suction should be placed on the center of gravity of the product above, and then electrified, to prevent light iron splashes;
 
When lifting, the working current should reach the rated value before lifting;
 
(3) landing electromagnetic sucker, to pay attention to the surrounding situation, to prevent injury;
 
(4) in the lifting, to pay attention to metal products and electromagnetic sucker should not have between non-magnetic articles, such as wood, sand and stone, otherwise it will affect the ability of lifting;
 
To carefully check the parts of each part, found damaged should be replaced in time;
 
6 in the process of hoisting, special attention should be paid to safety, not allowed in the equipment or personnel head through.
 
I. product introduction
