Belt Conveyor
For the raw material conveying scenario in the cement/building materials industry, INVT provides a long-distance, high-reliability variable frequency drive solution to ensure stable feeding of the conveyor.
For the raw material conveying scenario in the cement/building materials industry, INVT provides a long-distance, high-reliability variable frequency drive solution to ensure stable feeding of the conveyor.
High energy consumption and high cost: Adopting power frequency drag + hydraulic coupling, the motor runs at rated speed for a long time, with much ineffective energy consumption, low efficiency and poor operation economy.
Fast mechanical wear: Severe impact caused by motor start and stop leads to wear of mechanical parts and shortens equipment service life.
High maintenance cost: Belts (elastic materials are easy to wear) and hydraulic couplings need frequent inspection, repair and replacement, and maintenance cost accounts for a high proportion.
INVT adopts GD series high and low voltage inverters to directly drive the motor, realizing soft start/soft stop of the conveyor, combined with master-slave control to achieve multi-machine synchronization, and integrating deviation detection and overload protection functions to ensure equipment safety.
Core Concept
Variable frequency direct drive + master-slave coordination to realize stable start-stop and energy-saving operation of long-distance conveyors.
Technical Proposition
Synchronous direct drive: Eliminates the reducer and hydraulic coupling, reducing procurement and maintenance costs.
Stable start-stop: Soft start-stop + S-type acceleration and deceleration, greatly reducing mechanical impact and extending mechanical service life.
Master-slave coordination: Master machine speed/slave machine torque mode, the tail slave machine adopts torque setting + speed limit to avoid belt slipping and ensure power balance.
Synchronous direct drive eliminates gearboxes, reducing procurement and maintenance costs with obvious power saving.
Soft start/stop + S-curve acceleration/deceleration reduce mechanical shock; belt starting tension lowered by 30%, greatly extending idler and pulley life.
Master speed/slave torque mode, tail slave with torque reference + speed limit to avoid belt slip, ensure power balance and control current fluctuation within 20A.
