The four-mile-long Lee Tunnel – London’s deepest tunnel to date – will prevent 16 million tons of sewage from entering the river each year. At the end of the tunnel lies the Beckton Pumping Station, which is part of Britain’s largest wastewater and sewage treatment facility. A total of 6 KSB pump sets will be installed in a shaft structure located 85 meters below the Beckton Pumping Station; these pumps will be used to handle both stormwater and sewage.

Wear-resistant white cast iron is used for the wastewater pumps. Motors with a voltage of 6,600 volts and a power rating of 3.4 MW, controlled by frequency inverters, will be used to drive these pumps. To keep these motors cool, KSB will use heat exchangers specifically designed for use in underground applications. Compared to conventional air-cooled systems, these heat exchangers significantly reduce the amount of energy needed to dissipate heat. The use of white cast iron makes the wastewater pumps more wear-resistant, ensuring a longer service life

The use of white cast iron makes the wastewater pumps more wear-resistant, ensuring a longer service life. The 4-mile-long Lee Tunnel, London’s deepest tunnel, can prevent 16 million tons of sewage from reaching the river each year. At the end of the tunnel is the Becton pumping station, which is part of the largest wastewater and sewage treatment facility in the UK. Inside the shaft structure located 85 meters below the Beckton pumping station, there are 6 KSB pumps used to transport stormwater and wastewater after they have been collected. The wastewater pump is made of wear-resistant cast iron. The wastewater pump is driven by a 6600-volt, 3.4-megawatt, frequency-inverted motor. To maintain the cooling of these motors, Cemex adopted a special heat exchanger design for this underground facility. Compared to equivalent air-cooled systems, these heat exchangers can significantly reduce the energy required to eliminate an equal amount of heat load. White cast iron makes wastewater pumps wear-resistant and ensures a long service life. I don’t understand; give it a try and look it up. :handshake

This post was last edited by windman09 on 2015-9-20 at 10:59. The four-mile-long LEE tunnel is the deepest tunnel in London; it prevents 16 million tons of sewage from flowing into the rivers. At the end of this tunnel is the Beckton pumping station, which is part of the largest wastewater and sewage treatment plant in the UK. 6 KSB sewage pumps are installed vertically 85 meters below the pump station to transport rainwater and sewage.

The sewage pump is made of wear-resistant white cast iron. The sewage pump is driven by a 6,600-volt, 3.4-megawatt variable-frequency motor. To cool the motor, Kaisberg designed a special heat exchanger for this underground unit. Compared to air-cooled systems, these heat exchangers significantly reduce the energy required to eliminate the heat load. White cast iron makes sewage pumps wear-resistant, ensuring a longer service life for the pumps.

The four-mile long Lee Tunnel – London’s deepest tunnel – will prevent 16,000,000 tons of sewage from entering the river each year. At the end of the tunnel is the Beckton pumping station, part of which is the largest wastewater and sewage treatment plant in the UK. A total of 6 sets of KSB pumps will be installed at the Beckton pumping station, below an axis structure at a depth of 85 meters, to transport both rainwater and sewage. Wear-resistant cast iron will be used for the wastewater pumps; a voltage of 6600 volts with a rated power of 3.4 megawatts, along with frequency converters, will be used to drive these pumps. To cool these motors, KSB will deploy specially designed underground heat exchangers. Compared to equivalent air-cooled systems, these heat exchangers will significantly reduce the thermal load associated with energy consumption. White cast iron makes wastewater pumps wear-resistant and ensures a long service life. You can use Baidu, right? . .

Wear-resistant white cast iron is used for the wastewater pumps. 6,600-volt motors with a capacity of 3.4 MW, controlled by frequency inverters, will be used to drive these pumps.

Compared to conventional air-cooled systems, these heat exchangers significantly reduce the amount of energy needed to dissipate heat. The use of white cast iron makes the wastewater pumps more wear-resistant, ensuring a longer service life. One end of the Lee Tunne tunnel is the Beckton pumping station, which is part of the UK’s largest wastewater and sewage treatment plant. A total of 6 KSB pumps have been installed here; they are situated in a shaft 85 meters underground at the location of the Beckton pumping station. The main purpose of these pumps is to transport rainwater and wastewater collected from the surrounding area. The material used for sewage pumps is wear-resistant white cast iron; this material offers advantages such as wear resistance, which ensures a long service life for the pumps. The sewage pump is powered by a 6600V high-voltage motor with a rated power of 3.4MW, and it is controlled using frequency conversion control. To ensure the proper operation of the water pump at a depth of 85 meters, a dedicated cooling heat exchanger will be installed during design to cool the motor. Compared to air-cooled units with equivalent performance, these heat exchangers will significantly reduce the heat load of other additional losses required for cooling the motor. That’s what I mean, right? I’ve also adjusted the sentence order for you. foreigners often speak in a rather messy way too.... The whole text seems to convey the essence of a presentation or report on a design scheme
