We had to come up with a solution to avoid further damage to the streets and the sewage system. This proved a challenge in more than one way: the bypass would have to handle the significant flow fluctuations throughout the day and cause minimal disruption to residents and passersby.
The maximum flow demanded by the customer was 3200 m³/h. In order to meet this demand and control the flow variation, the pumps had to operate in parallel AND had to be equipped with a flow alteration system. This system ensures that the flow provided by the pumps automatically matches the prevailing flow demand.
Furthermore, to minimize the disruption, the surface pipelines of the installation had to be laid on the ground over a length of 350 metres. The extra difficulty here was the 2 x 16 inch diameter of the pipe in combination with the high pressure demand. Normally a pipe with a large diameter requires about 8 lines of 8-inch holes.
Inserting the large number of bolts and screws needed to weld all these different sections of the pipe together would be very time-consuming. We thus needed to come up with an innovative solution and designed a pipe without joints, where the ends of the pipes can be slided into one another.
The advantages of this innovation? Along with a rapid assembly, it saves the client a lot of money.
With the local residents and passersby in mind, we equipped the pump installation with the newest vacuum automatic priming technology. This technology reduces the level of noise emanating from the diesel pumps. It creates a vacuum that removes any air present from the suction piping and pumps. As the vacuum level increases, the water level rises at a predictable rate until each pump is fully flooded . Compare it to a propeller that pushes the liquid through the pump.
“ The reactive and creative mindset of our team really made the difference. The customer appreciated the innovative solution we designed especially for them. This project has created many new opportunities and has put Atlas Copco Rental on the map!
The customer’s project team even received a special company prize for the innovative operational technology ”
