Product Description:
The YBZD series explosion-proof type vibration three-phase asynchronous motor (abbreviated as explosion-proof vibration motor) operates on a principle similar to that of general-purpose vibration motors, utilizing high-speed rotation of eccentric blocks at both ends to generate vibration force as the vibration source. This series of explosion-proof vibration motors boasts advantages such as reasonable design, compact structure, high excitation efficiency, energy-saving, long service life, reliable operation, and easy installation and debugging. They can serve as vibration sources in explosion-proof environments for vibrating hoppers, vibrating screens, round vibration screens, vibrating feeders, and vibrating conveyors. Their explosion-proof performance conforms to GB3836.2-2000 "Electrical equipment for explosive gas environments – Explosion-proof type 'd'". The explosion-proof marking is ExdⅡBT4, suitable for use in Class II A, B groups T1~T4 flammable gases or vapors mixed with air in explosive mixtures.
The YBZD explosion-proof wall vibrator is an energy-saving general-purpose product driven by an explosion-proof vibration motor. It effectively eliminates phenomena such as bridging, arching, and blockages caused by internal friction, deliquescence, electrification, and component segregation through high-frequency vibration and impact force, ensuring the smooth discharge of materials from the hopper and the necessary equipment for stable material supply.
The YBZD series material storage vibration anti-blocking device (warehouse wall vibrator) is a specialized equipment designed to prevent and eliminate phenomena such as material arching, pipeline blockages, and sticking in material storage, bins, or gates, ensuring smooth material flow and enhancing the automation level of material transport. It can be widely used in various industries including power, construction materials, coal, chemicals, metallurgy, casting, light industry, food, grain, and transportation.

This series of explosion-proof vibration motors boasts advantages such as reasonable design, compact structure, high excitation efficiency, energy-saving, long lifespan, reliable operation, and easy installation and debugging. They can serve as vibration hoppers, vibration screens, round vibration screens, vibration feeders, and vibration conveyors in explosion-proof environments.
III. Application:
Explosion-proof motors are primarily used in coal mines, oil and gas, petrochemical, and chemical industries. Additionally, they are widely applied in sectors such as textiles, metallurgy, urban gas, transportation, grain and oil processing, and papermaking.
Section 4: Maintenance and care for YBZD explosion-proof vibration motors
Proper maintenance and care of the vibration motor ensure safe and reliable operation, as well as prolong its service life.
1. The bearings of explosion-proof vibration motors should be regularly (every 1000 hours) lubricated with Shell Eneos EP2 high-temperature grease by using an oil gun into the bearing chamber. The recommended grease volume per bearing is 5-10cc. Do not use lubricants from other brands.
2. The machine should be disassembled for maintenance and inspection after a cumulative operation of 5,000 hours. Clean the bearings and bearing covers simultaneously, inspect the bearings, replace heavily worn bearings, and then fill with grease to occupy 1/3 to 1/2 of the space volume.
3. The machine has been in stock for over half a year; it is necessary to disassemble, clean, and replace the oil in the bearings before installation and use.
4. The machine must undergo a thorough cleaning annually, including washing away accumulated dirt and oil inside the motor. This task can be done simultaneously with the oil change.
V. Technical Specifications:
Section 6: Installation Location and Method:
1. Full steel plate material storage silo: The YBZD type unit should be welded onto the wall surface of the storage silo.
2. Full concrete storage silos and reinforced-steel-reinforced material silos: Vibrating plates should be installed inside the silos, and the YBZD anti-blockage device should be welded onto the vibrating plate.
3. The upper section is a concrete storage bin; the lower section is a steel hopper. The YBZD anti-blockage device should be welded to the surface of the dry material wall.
4. Storage silos for pure rough bulk materials: Regardless of the form, vibration plates should be installed inside the storage silos for this material. The YBZD-type device should be welded onto the vibration plates.
5. Chute: The YBZD type anti-blockage device should be welded at the parts of the chute where it is prone to sticking and material blockage.
The YBZD type anti-blockage device should be installed on the vibration wave antinode segment of the installation surface, which is located between one-third to one-fourth of the total length from the top or bottom edge of the installation surface.
