Fluidtronik delivers in record time
3rd Quarter 2010
Hydraulic systems & components
Fluidtronik recently completed the first of two orders worth 5 million rand each for Bosch Projects, a specialised sugar equipment supplier based in Durban.
This involved delivery of the complete hydraulic system for a chainless diffuser to be installed in the state of Bihar in India. It was delivered within a staggering eight weeks from the date of order. This included detailed design, manufacture, assembly and full in-house testing.
The system comprised a Retract Motion Control system and a Forward Motion Control system. These were made up of:
* 24 heavy duty hydraulic cylinders.
* 24 control blocks integrated on the cylinders.
* Four power pack units.
* Four transducer panels.
* A nonwelded piping system.
* Electrical prewiring
In addition 12 off LVDTs were integrated within each of the forward motion cylinders for accurate position control.
Unique features
Fluidtronik incorporated several unique features into the design: stainless steel reservoirs were used to prevent internal corrosion caused by condensation; a failsafe control system allowed the cylinder to float whilst the opposite cylinder was being activated; pump unloading through the LS vent allowed for an extra smooth decompression stage before switching direction solenoid valves; and heavy duty cylinders with a unique sealing and bearing design were used.
In addition pressure transducers monitored the individual diffuser screen loading and served as an interlock to switch the direction of the control valve only when pressure was decompressed. The leak-free piping system was flared and flanged with no welds.
Successful simulation
Before shipping the system to India. Fluidtronik built a mockup of the diffuser in order to simulate and test the complete hydraulic system together with the instrumentation. The in-house tests were very successful. Fluidtronik now has the ability to pre-test and ship this type of system anywhere in the world.
Bosch Projects has more projects in the pipeline in Africa, India and Brazil and Fluidtronik is looking forward to supplying many more of these systems.
Heinz von Fintel, MD of Fluidtronik, elaborates that this achievement was made possible by his hardworking, motivated team of engineers and artisans as well as excellent service from numerous reputable suppliers.
He is very proud of the quality of the product and the professional approach his company displayed in executing the project.
