KBX-220 explosion-proof tilt switch

Application of KBX-220 explosion-proof tilt switch

The kbx-220 explosion-proof inclined blockage switch is a detection device used to detect whether there is blockage in the feeding part of the kbx-220 explosion-proof inclined blockage switch during the conveying of loose materials in the belt conveyor. The kbx-220 explosion-proof inclined blockage switch can be installed on a wall surface tilted at a 60 degree angle to the ground< Br/>
When the explosion-proof tilt switch is vertically suspended and deviates from the vertical position by more than 15 degrees due to external force, the internal contacts of the switch will act, and the normally closed contacts will open (or the normally open contacts will close). After the external force is removed, the tilt switch returns to the vertical state, and the contacts close (or open) again. Use the changes in the opening and closing of the internal contacts of the tilt switch to determine the working condition of the equipment, so as to take timely measures to protect the equipment< Br/>




Tilt switch, also known as coal flow switch, mercury switch, material level switch, coal blockage switch, or material level switch. It is a simple structure, convenient to use, and reliable material flow and level. It is small in size, easy to install, sturdy and corrosion-resistant. Usage: Blockage detector at chute or junction; Conveyor belt deviation detector; Dumping machine unloading; Used for detecting material shortage or absence in belts and vibrating feeders. Introduce American technology and import internal components< Br/>
Working principle:

&Nbsp; When the tilt switch of the vertical suspension is subjected to external force and deviates from the vertical position by more than 15 degrees, the internal contacts of the switch will act, and the normally closed contacts will open (or the normally open contacts will close). After the external force is removed, the tilt switch returns to the vertical state, and the contacts close (or open) again. Use the changes in the opening and closing of the internal contacts of the tilt switch to determine the working condition of the equipment, so as to take timely measures to protect the equipment< Br/>




Characteristics of tilt switch:

Can be used in harsh environmental conditions. Due to the sealed nature of the mercury switch, the internal mercury is isolated from the outside, making it suitable for use in environments with oil, steam, dust, and corrosive gases< Br/>
The external force required for connection and disconnection is small. Mercury is the only metal that can maintain a liquid state at room temperature. Its surface tension and specific gravity are relatively high. As long as a slight external force is applied to tilt the mercury switch, the mercury can move, enabling the switch to turn on and off< Br/>
Mercury has good conductivity, and the contact resistance between mercury switch electrodes is generally less than 100m&Omega< Br/>
The allowable current for mercury switches depends on the material of the electrode. The maximum allowable current for magpie wire electrodes is 10A, while for general alloy wires, the maximum allowable current is generally 1A< Br/>
Due to the fact that the on-off of the mercury switch is determined by the gravity of mercury, it can operate reliably for a long time< Br/>
The contact point of the electrode is liquid contact, without any noise< Br/>
Due to the ability of mercury to flow, as long as the acceleration reaches the set value or above, the mercury switch can be turned on or off, making it suitable as a vibrating element< Br/>
Small in size, diverse in form, and fully sealed devices< Br/>
Simple structure and low cost< Br/>
