The "H" brand designates general purpose vibrators of increased reliability. Such vibrators are designed to excite vibration in installations for compacting concrete mixtures and soils, transporting, unloading and sieving bulk materials, driving vibratory feeders, vibrating pads and other technological works, including for mini brick block installations.
Vibrators are a three-phase asynchronous electric motor with a short-circuited rotor with unbalances mounted at the ends of the rotor shaft. The unbalances, rotating with the rotor shaft, create a driving force.
To regulate the magnitude of the driving force of the vibrator, the unbalances at both ends of the shaft are double. The adjustment is carried out by changing the angle between the movable and fixed unbalances at both ends of the shaft. It makes sense to use these models at high loads and long-term inclusions, which happens exclusively in large-scale industries. The vibrator of increased reliability is increased dust and moisture protection, cast-iron shields, increased strength of windings, selective assembly. Increased working life (at least 3 times).
