Section One Principle of action

Electrostatic impurity removerIt is composed of an electrostatic suction cup (or handheld stick) and a DC high-voltage power supply. The DC high voltage power supply provides positive high voltage to the electrostatic suction cup (or handheld stick), causing the electrostatic suction cup (or handheld stick) to emit negative positive electricity,,Then, the object (workpiece) is charged (artificial charge). The higher the voltage, the larger the effective range.

Section Three Installation and Usage

1Grounding: Ground the output grounding terminal of the DC high-voltage power supply to ensure that the resistance between the DC high-voltage power supply casing and the ground is less than or equal to10Oh.

2Connect to high voltage: Insert the high voltage input plug of the electrostatic suction cup (or handheld stick) into the output socket of the DC high voltage power supply, and lock it with the nut provided on the high voltage plug.

3Connect the control plug:

（1）Controlled by external contact points, one end of the contact is connected to the control plug“2”The other end of the foot and contact is connected to the control plug“3”Feet, “1”Feet are empty. When the contact is connected, output high voltage; Stop outputting high voltage when disconnected.

（2）Controlled by input voltage, positive pole connection is required“1”Foot, negative pole connection“3”Feet,

“2”Feet are empty. The input voltage is5V～12VBetween, the input current is greater than1mAWhen there is input voltage, output high voltage; No input voltage, stop outputting high voltage.

（3）Controlled by photoelectric switch. The photoelectric switch must beNPNNormally open type, brown wire connection for photoelectric switch“1”Foot, blue wire connected“2”Feet, black wire connection“3”Feet. When the photoelectric switch is closed, it outputs high voltage; When the photoelectric switch is turned off, it stops outputting high voltage.

Close the power switch on the high-voltage supply, adjust the control output voltage range, input the control signal, the indicator light will turn on, and output the appropriate DC high voltage.

Section 4 Precautions

1The charging effect of high-voltage suppliers is closely related to the structure and installation of electrostatic suction cups (or handheld sticks). Generally, the distance between the installation of electrostatic suction cups (or handheld sticks) and objects is80-100MMbetween.

2Do not use the electrostatic precipitator in flammable and explosive environments.

3The grounding terminal of the electrostatic impurity remover must be truly grounded, otherwise it will affect the charge effect and cause unsafe factors.

4Do not aim the firing needle of the electrostatic suction cup (or handheld stick) at the human body.

5The electrostatic suction cup (or handheld stick) has a short-circuit protection device inside, but it should be avoided to output frequent short-circuit ignition, otherwise the protection device will also be damaged due to fatigue.

Section Five Usage Tips

1、 High voltage supply device

1The output voltage of the high-voltage supply should not be adjusted too high at first. It should gradually increase from small to large, based on the principle of meeting the requirements. Setting the voltage too high not only wastes electricity but also poses safety hazards.

2The high-voltage supply is equipped with high-capacity capacitors inside. When the high-voltage supply is started, charging requires a certain amount of time (＜3The output voltage can only reach the rated value in seconds. Similarly, after the high-voltage supply is shut down, it takes a certain amount of time for the output voltage to drop to“0”. When repairing the electrostatic emitter (rod), it is necessary to stop the machine for sufficient time or use a wire to discharge the static electricity of the emitter to the ground before touching the discharge needle.

IIElectrostatic suction cup (or handheld stick)

1The discharge needle of the electrostatic suction cup (or handheld stick) should be kept away from the metal mounting bracket of the emitter, preferably using insulating material as the bracket.

2In order to apply sufficient static electricity to the material, there must be a flat "metal pallet" or "metal mesh plate" on the back of the material to be charged with static electricity. This metal support plate is connected to the "earth", which is the working grounding of the DC high-voltage supply, in order to form a "circuit" for electrostatic discharge.

3In order to add sufficient static electricity to the material and prevent it from leaking (escaping) quickly after adding static electricity. The higher the insulation value of the material, the better. The drier the materials and ambient air, the better.

4It is best not to discharge the electrostatic discharge needle towards the bare metal plate, as the area of the material subjected to static electricity is equal to the area of the metal plate. If the area size of the material to be electrostatically charged changes and the area or length of the electrostatic suction cup (or handheld rod) cannot be changed, it is best to place a thick insulating material on the bare metal support plate to cover it, or cover the discharge needle facing the bare metal support plate in a way that is conducive to the concentration of charges on the material that needs to be electrostatically charged.
