Drum - the use and protection

Drum is a key component of the camera, and the drum performance has a direct impact on the quality of the image after recording, so we use it to pay attention to protect. The drum has a head designed to detect the rotational phase of the PG video signal magnetic tip and a rotor mounted on the outer cylindrical surface of the drum motor of the two magnets of opposite polarity, and when the head and the magnet is damaged or bad, PG head available mono recorder instead of the recording head; magnet magnet can be used instead of (with tape glue). But pay attention to the polarity of the magnet to match; distance and position the head to the right.

Drum

In order to Magnetic Rods extend the service life of the drum, we have to do:
First, do not use in dusty places great camera.
Second, do not try to touch the drum surface, or is likely to cause damage to the head.
Third, we want to use the manufacturer's recommended use of the cleaning cartridge.
Fourth, the inferior surface of the tape on the head in terms of like a sandpaper, and old tape dropouts can cause serious head clogging, so we do not use inferior and obsolete tape.
Going out shooting, drum jams are likely to occur, in general we can through the following methods to clean the dirt on the drum.
First, the normal processing mode. We can make the camera enters playback status, remove the tape and put into cleaning tape, then press the playback button, about ten seconds or so cleaning can be, this is a more thorough cleaning method.
Second, the simple approach. When using this method, we must first stop the camera into playback mode, press PLAY playback button, then press REW quick search key, so that the relative speed of the drum with the highest tape, lasted about 15-20 seconds. and then back to the camera state, to find just the end of the recording, then we can continue a normal camera. Often this method is suitable for tape is relatively new and usually very careful to use the machine's environment.
Third, other magnetic name tag treatment methods. When out of the house forgot and easy handling and cleaning does not work, we can get a new tape into the cassette in the camera state to open menus to adjust to the LP mode, then remove the menu, press the camera button camera, About 10-30 minutes later and the machine can be a normal camera up. When the checks have been after a good cleaning, but also to re-adjust to the SP mode in order to get a better film quality.

Separators Precautions

8.1 electromagnet should be measured before the cold insulation resistance at room temperature, its value is not less than 10MΩ.
8.2 electromagnet is not poised on the matter being sucked Do not energized before work. Forbidden to use electromagnets to make trips hammer.
8.3 Materials must be selected relatively flat parts of the suction lift.
8.4 requires high temperature materials electromagnet suction lift, lifting electromagnets normal temperature normal temperature materials is prohibited lifting electromagnet normal temperature hot object.
8.4.1 forbidden to stay in the high-temperature objects electromagnet waiting to be sucked surface temperature drops below 600 ℃ before the magnet close to the work.
8.4.2 When not in use, is strictly magnetic hooks prohibited electromagnet stay at high temperatures, hovering, storage.
8.4.3 minimize contact time electromagnets and hot objects.
8.4.4 If in the course of the electromagnet suction decreased or poles appear overheated, should be allowed to rest for some time electromagnet.
8.5 electromagnet load's center of gravity should be as symmetrical placement.
8.5.1 Note eccentric longitudinal direction, the center of gravity of the material to be sucked lifting.
8.5.2 electromagnet payload = suction weight capacity × (1 + eccentricity / space), so the spacing between the lifting electromagnet is better to be slightly larger. When the spacing between the two electromagnets small eccentricity is large, both with a deadweight electromagnet electromagnet is almost the same, the work would be extremely unsafe. The pitch can not expand the occasion, the operation should minimize the amount of eccentricity to make work safe and reliable.
8.5.3 For longer difficult to produce around the degree of steel solenoid load larger, generally using multiple combined. In this way, the suction surface level is very important, should adopt the balance-type two-beam ceiling. Except for special reasons, the use of four electromagnets, so that the hanging chain the accuracy requirements of the class is much smaller, easy to practice, commissioning and use.
8.5.4 When using more than four units when lifting electromagnets, electromagnetic adsorption surface should be carefully adjusted to suit the actual working conditions, there would be not only ineffective individual electromagnet, but will also add weight to increase the other electromagnet burden.
8.5.5 when used in combination of two materials whose spacing is half the length.
8.6 With the crane lifting electromagnet, to avoid smashed pull off the power cable.
8.7 in the operation to regularly observe the solenoid control screen voltage and current indicated value.
8.7.1 solenoid excitation current should be in the cold between the current and the thermal state current.
8.7.2 voltage allows the error does not exceed ± 10%.
8.8 electromagnet should be kept dry, non-water-cooled. After use, should be stored in dry, ventilated place no harmful substances.
8.9 Always check the chain, pin wear. Less than 90% of the original diameter, replace genuine.

Separators electrical performance

5.1 solenoids repeated short-time work status of the solenoid duty cycle TD is generally 60%
I.e. TD% = [tp / (tp + tn)] × 100%
tp as working time, tn as rest time.
Ie solenoid is energized to lift the material sent from the destination to the release of material being sucked entire period of time is working time tp, time to return to the original magnetic sweeper position of rest time tn, a cycle of work and rest time.
5.2 the rated continuous power voltage and 60% of the intermittent operation, the solenoid coil temperature rise reaches a stable value, the current time is the thermal stability of the current, the coil current is not higher than the thermal current coil generally does not appear coil burning and insulation down and so on.

Updating of equipment; ensure good lubrication is the key to extend its service life. Dry magnetic separator when open gear lubricant should be sufficient,

While bearing cover hole injection, then at least once every three months, you have to grease, as this will ensure the life of the machine, saving costs while improving efficiency.

Magnetic Separator in rougher tailings slurry with a high concentration when the characteristics of understanding, under normal circumstances, it should be ready to remove the pulp of wire rod head or the like

So in order to avoid a small amount to the mine when the time, these things may not come up with, then the tube will soon be worn or scratched leather production and cost are negative. This

When the cylinder is a foreign body, you can shutdown observation hole through both ends of the inspection. Ore magnetic separator has the following six characteristics:

1, to the mine rinse water to make a slurry into a high concentration can be diluted and adequate separation, magnetic separation to make a good effect, the magnetic separator for coarse-grained magnetite coarse

Select the slurry having a high concentration feature. Magnetic separator tailings flow channel division is running fine before and after the overflow or fine mud tailings and tailings underflow orifice then ran around coarse particles

Stone dykes, suitable for roughing coarse magnetite slurry has a particle size distribution is very wide, coarse or very different characteristics of the high clay content.

2, the downstream groove, making pulp larger particle size, which does not cause heavy coarse groove plug, suitable for coarse-grained magnetite mineral rougher when coarser features.

3, because the equipment sorting drum surface field strength is high, the pulp can be given directly to the ore bucket sorting higher field strength cylinder surface area, making it difficult to be adsorbed and easy flow of the magnetic

Lost in the coarse tailings iron with the living body, the higher magnetic force can be effectively adsorbed on the surface of separation tube. 4, magnetic separator has a higher surface mine, the larger the magnetic wrap angle

Makes sorting with a long, iron magnetic minerals are adsorbed recovered fully, so magnetic material high recovery rate. Separator applications currently expanding scope and

magnetic Basics

Magnetic materials is an important foundation for the electronics industry functional materials, widely used in computers, electronics, communications, automotive and aerospace industries and household appliances, children's toys and other daily necessities, as the world economy and the rapid development of science and technology, unprecedented demand for magnetic broad. The development of China's current magnetic ranks first in the world, has become the world's largest permanent magnet material production in the country.
Magnetic
    Functional devices used in the magnetic sweeper manufacture of magnetic material called magnetic materials. The classification are: permanent magnet material (also called hard magnetic material), soft magnetic materials, semi-hard magnetic materials, magnetostrictive materials, magnetic thin film, magnetic fluid, etc., they are collectively referred to as functional magnetic material.
Permanent (hard) magnetic materials and soft magnetic materials
    Magnetic materials, also known as hard magnetic material when the magnetic field is removed, the material still having magnetism; soft magnetic material when the magnetic field is present, a high magnetic flux density, when the magnetic field removed, the loss of the magnetic materials. This does not refer to a hard and soft on the mechanical properties of the hard and soft, but rather on the magnetic properties of the hard and soft. After literally means applied magnetic magnetized magnetic material to be able to retain their ferromagnetic long (short magnetic), characterized in that the high coercive force. Coercivity magnetic material magnetized later that a residual magnetism after demagnetization (residual magnetic flux density and residual magnetization) of the magnetic field strength is reduced to zero. The soft magnetic material is both easy magnetization of magnetic field, and easy to demagnetization, the low coercivity magnetic material. Refers to the applied magnetic field demagnetization (referred to as magnetic field) after magnetizing the magnetic material, combined with the Drawer magnets  of the magnetic field in the opposite direction to decrease the magnetic field.
Bonded permanent
    Bonded permanent plasticity refers to the binder material is a blend of the permanent magnetic powder to plastic powder, through a variety of plastic materials molding process to obtain a composite magnetic body. In the whole process of forming the adhesive physical changes occur, with the powder particles together and made of magnet is called a bonded magnet.
Sintered Magnet
    Application of powder metallurgy, materials made of powder will burn, molding made of rough, then made of sintered magnets.
Neodymium iron boron (NdFeB)
    Is a new kind of magnetic material NdFeB ternary intermetallic compounds, is all magnetic materials magnetic energy per unit volume contains the largest of a permanent magnet material. Made of NdFeB bonded magnet powder with this the magnets can be strong, temperature stable performance, high precision forming of complex shapes without the need for post-processing of parts, and has good corrosion resistance and good toughness, widely used in computer disk drives voice coil motor (VCM), magnetic resonance imaging (MRI) equipment and a variety of audio-visual equipment, microwave communications, magnetic machine (magnetic pump, magnetic valve), household appliances and maglev trains and other fields.
Ferrite
    Ferrite is iron oxide (Fe2O3) based oxides of other elements reaction of a ferrous compound.
Calcined ferrite material
    Iron oxide red (or iron scale) and strontium or barium carbonate and a small amount of materials, according to a composition ratio after mixing, at a certain temperature below the sintering atmosphere, through a raw material in the solid phase reaction between MO6Fe2O3 (where M as Sr, Ba) ferrite.
Ferrite Materials
    Ferrite material is strontium ferrite and barium ferrite, ingredients SrFe12O19 and BaFe12O19. Has a magnetic quality, high cost performance, good stability, is the world's largest amount of magnetic functional materials. Widely used in permanent magnet motors, speakers, and magnetic retention, electronic deflection, etc., including automotive, communications, audio, video recorders, televisions, radios, microwave ovens, refrigerators, magnetic separation equipment, medical equipment, computer peripherals, office automation equipment, children's toys, and many other fields.
Isotropic and anisotropic materials
    Permanent magnet materials based on single-domain grain orientation were divided into: isotropic material, rough shape when single-domain grains are disordered; anisotropic materials, grain rough shape when under the effect of the orientation field arrangement is orderly.
Magnetic Recording
    The basic principle is that the magnetic field into electrical signals input to the recording head to the coil, so that the gap at the head produce a corresponding change in the magnetic field, if this magnetic recording medium having a magnetic tape at a constant speed immediately adjacent to the head through gap, the magnetic field must be the change magnetization hysteresis and will remain as the input signal corresponding to the track, which is a simple recording process. Conversely, if the magnetic tape after a certain speed is achieved by the reproducing head gap, the magnetic head coil will induce a change in the track corresponding to the electrical signal is amplified and then converted to the original input signal, which is magnetic read out the regeneration process.
Nano-magnetic materials
    A nanometer is 10-9 meters middleweight, will nanoscale magnetic material powder whose performance has changed fundamentally, the main applications are: nanocomposite permanent magnetic materials, permanent magnetic materials and soft magnetic materials by mixing powder then After processing, the permanent magnet material can be very high magnetic properties. Also made of powder particles of the material to achieve sub-micron level, with Chengchou structure, excellent performance can be obtained permanent magnet. It can increase the production of magnetic recording materials than dry sound, improving image quality; made of magnetic liquid is a very good sealing material. In addition, you can use magnetic nanomaterials as anticancer drugs magnetic carrier; cell separation medium magnetic materials; copier toner and magnetic ink and magnetic printing.

the electromagnet is characterized by what

the electromagnet is characterized by what
Electromagnet has many advantages: you can use the presence or absence of magnetic solenoid off through current control; magnetic size can use the current strength or coil turns to control; also change the resistor to control the size of magnetic control current drum separator size; it The pole can be controlled to change the direction of the current, and so on. Namely: the strength of the magnetic can be changed to control the presence or absence of magnetism, the magnetic pole direction can be changed, the current may be due to the disappearance of the magnetic disappear.

he electromagnet works

Solenoid is energized to produce a magnetic, like a magnet can be adsorbed ferrous objects. Electromagnet can be applied to a variety of areas, such as large amusement equipment, automotive, aerospace, industrial, and other undertakings. Common applications such as solenoid: punch the time clock at work, the supermarket cash register, Drawer magnets  enter the number of units of automatic doors. These electromagnets by the magnetic field energy is converted, and then the magnetic force generated by the magnetic field acting on the center of the electromagnet core, the core movements. The main application is the core of the electromagnet forces generated by movement. This can be done a few grams minimum force tens of grams, in theory, can do infinitely large, basically able to do almost a hundred kilograms. The magnetic effect of the current is the current that the magnetic field around the. The electromagnet is energized, the current through the coil generates a magnetic field, the magnetic field generated in the core operation.
