DY Controllable Electro Hydraulic Transmission

• 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.

• Draught fan, Water pump centrifugal)

• Belt conveyor crusher
