The direction of the magnetic field of the electromagnet can be judged by Ampere's rule.Amperidine is a rule that indicates the relationship between the direction of the magnetic induction line of the current and current excitation magnetic field, also called the right-handed screw rule.(1) Ampere's

When the iron core is inserted inside the energizing solenoid, the iron core is magnetized by the magnetic field of the energizing solenoid. The magnetized iron core also becomes a magnet, so that the magnetic properties of the solenoid are greatly enhanced because the two magnetic fields are superi

1. It adopts a fully sealed structure and has good moisture resistance.2. Optimized by computer, the structure is reasonable, the weight is light, the suction is large, and the energy consumption is low.3. The excitation coil is treated by special process to improve the electrical and mechanical pro

Lifting electromagnets have many advantages: the presence or absence of the magnetism of the lifting electromagnet can be controlled by on/off current; the magnitude of the magnet can be controlled by the strength of the current or the number of turns of the coil; it can also be controlled by changi

A device having an iron core inside and having a magnetic coil like a magnet is called an electromagnet. The iron core is made of soft iron or silicon steel which is easily magnetized and easily disappears. Such an electromagnet is magnetic when energized, and disappears after power is turned off. E

The screw buckle is mainly made of copper, iron and other materials. The surface is electroplated. It is generally used with chains and open rings. It is mainly used for toy accessories, craft jewelry accessories, gift accessories, etc. as pendants or decorations; There is a nut for locking at the o

It is made of high-quality products 1Cr18Ni9Ti or SS304 stainless steel. It has the characteristics of acid resistance, alkali resistance, cold and heat resistance, long service life, etc. It is widely used in food, chemical, pharmaceutical, rubber, printing, silk and other machinery, and for vario

The sprocket should be mounted on the shaft without skew and sway. In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprocket is less than 0.5 m, the deviation is 1 mm. When the center distance of the sprocket is 0.5 m

1. The allowable wear value of the chain shall not exceed 10% of the diameter of the ring chain or the thickness of the accessory;2. From the plane where the main ring is not bent, the main ring is distorted by more than 10 degrees and should be scrapped;3. Cracks appearing in any part of the chain,

1. In order to remove the play of the entire chain, it is measured under a certain degree of pulling tension on the chain;2. When measuring, in order to minimize the error, measure in the 6-10 section (link);3. Measure the number of the inner side L1 and the outer side L2 between the number of rolle
