1.3 Introduction of product typical applications
⚫
The products are widely used in thermal power generation, hydropower, transmission and distribution equipment,
metallurgy, chemical industry, mining, construction and other industries.
⚫
Water pump---Using the soft stop function, the water hammer phenomenon of the pump is relieved when the pump is
stopped, and the cost of system maintenance is saved.
⚫
Ball mill-Using voltage ramp to start, reduce the wear of gear torque, reduce maintenance workload, save time and
save money.
⚫
Fan--Reduce belt wear and mechanical impact, saving maintenance costs.
⚫
Compressor---Using current limiting to realize smooth starting, reduces motor heating and prolongs service life.
⚫
Belt conveyor---Realize a smooth and gradual starting process through soft start, avoid product displacement and
liquid overflow.
