Compressed air production system for Diesel - Electrical locomotives.
The compressed air production system supplies compressed air to pneumatic assemblies used in industry and transport, including locomotives.
The new Gardner Denver screw compressor used in producing compressed air for railway vehicles eliminates the disadvantages of other
systems in that it consists of a cooler and of a compact air end with a screw rotor driven by an electric motor by means of a belt.
The system for compressed air production is automated through a control unit that gathers information about the pressure and temperature of the air coming out of the air end and about the oil temperature in the oil sump. This unit autmatically controls the operation of the whole system.
Advantages of MIGHTYPROD's compressed air production system:
- easily installed;
- the cooler has separate cooling units for air and oil, respectively;
- the blades of the cooling fan are made of composite materials with iron core and can be replaced one by one;
- the system includes a filter for eliminating water out of the compressed air;
- the hood and the intake pipes for cooling air are fast and easily installed;
- the air end has double bearings at each end of the screw rotors;
- the system for compressed air production works automatically, without operators.
