Product description and schematic manner magnet
Adaptation:
Magnetic filter rods (magnet) mainly used to remove powder, granular and liquid or slurry ferromagnetic impurities, widely used in ceramics, electricity, mining, plastics, chemicals, rubber, pharmaceutical, food, environmental protection, paint, dyes, electronics, metallurgy and other industries.
How it works:
Magnet is made ​​of high quality stainless steel and high alloy NdFeB rare earth B values​​, and using a special production method is made. The holder can be combined in forming the cylindrical magnets filter. When the ferrous material through when attracted by the magnetic bar, a substance containing iron magnet firmly adsorbed on the wall, in order to ensure the integrity of equipment and product safety.
Product Features:
No energy, no pollution, can be installed on the production line can be anywhere in contact with the material, space-saving, easy installation, as a magnet NdFeB rare earth alloy magnetic source, strong magnetic force, simple structure, long life, specification style can be in accordance with customer requirements and production scene arbitrarily change the custom.

A drum-type magnetic separator

Magnetic separator can effectively remove the cooling fluid in the iron, consumes no filter. Easy to install, can be used with other forms such as the filter drum (drum) paper filter, flat comb paper filter, vacuum-type paper filter used in combination. Magnetic separator can be used according to customer requirements ferrite magnets, NdFeB or Alnico. Magnetic separator housing made of high quality materials, depending on the circumstances of carbon steel or stainless steel. Magnetic Separator Application: widely used in grinding coolant adsorption separation of impurities. In the painting, phosphating, cold and other industries have also been applied. Particularly suitable for CNC machine, EDM machine, polishing machine, Magnetic Rods gear cutting machines, grinders and other produce in the process of cooling liquid iron particles using the occasion. Magnetic Separator role: coolant consumption can be reduced so that the cooling pump, tool life increased. Workpiece surface quality Ra value can be increased by 30% for work, impurities easy to discharge machine maintenance time reduced by 50% Easy to install and no consumption of magnetic separator filter Main features: ● According to impurities in the coolant and oil situation morphological optional roller and comb-type magnetic separator magnetic separator ● roller type magnetic separator according to site specific conditions and an optional built-in motor ● To facilitate external adsorbed on the surface of the magnetic impurities fully falling, cot inner magnet type magnetic separator by a strong magnetic force can be designed into the structure of the fade, only the outer cylinder turn, reduce power consumption, energy saving significant. ● magnetic type comb Tooth type magnetic separator surface plus optional scraper conveyor mechanism and hydraulic flushing device to completely eliminate impurities, debris deposited solve the problem; For better drained moisture, comb-type magnetic separator level control switch also optionally add or time relay to make the gear motor intermittent operation ● For the convenience of customers using a magnetic separator into the water can be designed to last into the water or back into the water, the water can be designed around and under the water ● magnetic separator standalone traffic from 25 l / assigned to 4500 liters / min ● Three-phase geared motor voltage is 380 or 220 volts, geared motor according to user requirements placed on the right or left side ● PLC automatic control and manual control in two ways

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.

AC solenoids and DC solenoids issues

Rely on electromagnetic suction of two alternating magnetic field formed by superposition of a DC component of magnetic force to do work, and therefore inefficient, bulky core, coil and high energy consumption;
Low power factor, the coil current, severe fever, is a waste of energy and premature aging of the coil, damaged;
When the armature mechanical inlay cards, or overloaded, or low-voltage operation Dry Magnetic Separator with load difficulties, the coil will burn;
There frequency vibration noise. For the contactor, this vibration can lead to low voltage arcing contacts, contact burning, reduce product reliability and service life

;
Coil current, leading to bulky coils, causing the core bulky waste huge copper iron.
☆ ☆ ☆ DC solenoid

The whole process due to solenoid coil current is constant, so that more than 95% protection status of the energy is wasted energy is wasted for the heating coil, the coil hair

drum separator Hot and premature aging, damaged;
To reduce the heating coil, the coil wire diameter forced to increase, resulting in a huge waste of copper;
Coil volume increases, making the core volume increases, resulting in a huge waste of steel;

superconducting materials with DC solenoid problem

Resistivity of superconducting materials is almost zero, the resistivity of copper enameled copper resistivity. At room temperature, but can not make any conductors of a superconducting material, as

Temperature superconductors is usually -327 °.
    Or want to increase the magnetic force of the electromagnet, it must have a greater current power, a sufficient number of turns of the electromagnetic coil and a sufficiently large U-shaped core

, Magnetic Grate The specific needs complex calculations to calculate primary and secondary school is in an ideal condition, so the actual operation of a large deviation. Simply put, the line

The number of turns is proportional to the current size and magnetic, but too many turns, and the current will decrease, and this requires a large wire size (reduce the resistance, increasing current)

Increased diameter will increase the weight and volume, while providing enough power to a DC power supply. Various factors spurred the discovery and invention of the superconductor. magnetic bar But the super-

Conductor is an amateur can not be achieved under the conditions.
