• Automatic control
• Motor :no-load starting(when starting overload)
• Continuously viable speed
• On site/remote-control
• Multi-drive combination
Functions/Features
Working Principle
• Collecting instrument through various signal.
• The parameter of electro motor, hydraulic couplings, oil supply
system, working machine(including belt conveyor, draught fan,
water pump, crushers, etc will be sent to microcomputer
system of DY controllable system.
• Through computer programming, using the best control curve
to adjust the operation of hydraulic transmission device.
• Realize motor no-load start, work machine soft start and
continuously speed regulation.
Technical Advantage Of DY
• Intelligent automatic control
• DY electric hydraulic transmission device,
equipped with professional electric control
system, provides on site/remote control,
manual/automatic control ,etc
• Only need to set parameters, easily implement
intelligent programmable, soft start, multi-
drive power allocation, continuously speed
regulation
• Modular design
• DY series adopts modular design, dividing into
independent hydraulic drive mechanism and the oil
supply system
• (1) can reduce the noise and vibration of the
main engine
• (2) can greatly optimized oil supply system, such as:
can be a large fuel tank, a one-up oil pump group,
thus greatly improve the reliability of the equipment
• (3) design the mechanical part of hydraulic drive with
more compact connection, more stable structure, and
higher transmission efficiency
• Can control the fuel delivery system
• DY electric hydraulic transmission device, with the
independent oil supply station, can also be equipped with air
conditioning cooling system and water-cooling system.
According to the requirements of the equipment in the actual
operation, It can change with the environment and the
seasonal change, providing appropriate quantity of circulating
cooling, and automatically adjusting to the oil temperature to
a suitable range .
• According to the working condition requirements. It can also
realize the no-load motor soft start through the valve control
technology.
• A correct speed response
• DY electric hydraulic transmission device, using
independent research and development of the
core control technology, according to the
characteristics of hydraulic coupling, provides
professional computer programming to solve
the varied speed fluid coupling
• Control more accurately, with more sensitive
response.
• Simple electromechanical integration design
• DY electric hydraulic transmission device, with the use
of concise design
• Exquisite, powerful design.
• Belt conveyor crusher
