Lifting Electromagnet Tool Electric Lifting Magnets Big Size For Iron And Steel

1.MW electromagnet is widely used in smelt, casting and transportation department. It is a tool for conducting magnetic objects for carrying steel plate, steel casting , steel ingot, ingot, scrap iron and steel.

MW electromagnet is supporting the use of controlling equipment,cable reel and electronic weighing apparatus. It can effectively control electromagnet suction ,discharge and display weight value.

It has safe and reliable use.

2. Electromagnet are ensure of reliable work under the following conditions:

a,Not more than 2500 meters above sea level

b,Ambient air temperature is not more than 40 degrees Celsius, the minimum temperature is not less than -20

c,Non explosive hazardous and non corrosive gases in the environment

d,Ambient air humidity is not more than 90% (average temperature is 25 degrees Celsius)

e,Both indoor and outdoor use

Structure

Magnetic circuit is made of shell, iron core, out magnetic pole, inner magnetic pole and absorbed. The magnetic circuit parts are made of high quality steel and cast steel with low carbon content.Double glass fiber enameled aluminum or aluminum oxide film insulation with winding coil . Insulation material with H grade heat resistance grade .Its use of high wear resistance of high manganese steel. The inner and outer rings and the inner and outer magnetic pole welding seal cast epoxy resin to increase the waterproof, shock proof and insulation performance of the coil

Install and Use

1, An electromagnet is a large inductance component.

When the power is switched off, the high voltage back will be generated when the power supply is disconnected.It will cause serious and even burn control electric arc contact and breakdown coil. So it is necessary to match the power, and the discharge circuit of the special control equipment.

2, Electromagnet is generally used in crane, crane and other lifting equipment.

Cable drum must be installed in the middle of the transmission cable between the electronic control equipment and the electromagnet to avoid the lifting electromagnet when using the cable snapped.

3, Electric control box and cable reel are installed on different lifting equipment.

4, In the operation of electromagnet suction scrap, should choose flat stacking

This can play the suction of the electromagnet.When the material is electrified, the current is increased steadily, and then move to the discharge position to discharge the material, so as to shorten the time of the electromagnetic power supply. This can prevent the temperature rise is too high, to maintain the weight absorption capacity.

5, After the electromagnet discharge power, do not immediately power,

You should drive to the suction position, then energized suction.

Iron and steel scrap ahead of electricity will fly up to the bottom of the electromagnet is falling to cause a great impact on the electromagnet, it is likely to cause a short circuit of the solenoid coil. At the same time, it will cause the temperature rise of the electromagnet. Accelerating the wear of the magnetic pole to reduce the capacity of the electromagnet

6, High temperature type electromagnet for lifting high temperature steel.

7, After continuous use of the electromagnet, the temperature rise is too high, should avoid the use of cold water forced cooling.

8, Cable connector cable fastening should not loose. Before the cable plug should be carried out after the electromagnet has been cut off.

Care and Maintenance

1. Should regularly check whether there are cracks in the solenoid enclosure.

If it is found that cracks should be welded in time.

2, Each class before use to check whether the normal connectors and cables

Found abnormal should be processed in a timely manner

3, After long-term use, the insulation resistance of the electromagnet will drop

Please use 500V shake table to measure the thermal state of the electromagnet insulation resistance, should be more than 1M or more, or should be repaired in time

4, The chain and a pin used for a long time, found that more than 10% wear should be replaced

5, After long-term use, the electromagnet is found to decrease the suction, and the DC resistance of the coil should be checked. If the rated value is not reached, the coil of the electromagnet should be replaced.

6, Magnet for many years after the use of magnetic pole ground. If the height of magnetic and non-magnetic plate h less than 10 mm, should replace the pole
