BORSIG COMPRESSOR PDF

Main article: Scroll compressor A scroll compressor, also known as scroll pump and scroll vacuum pump, uses two interleaved spiral-like vanes to pump or compress fluids such as liquids and gases. The vane geometry may be involute , archimedean spiral , or hybrid curves. Often, one of the scrolls is fixed, while the other orbits eccentrically without rotating, thereby trapping and pumping or compressing pockets of fluid between the scrolls. Due to minimum clearance volume between the fixed scroll and the orbiting scroll, these compressors have a very high volumetric efficiency. These compressors are extensively used in air conditioning and refrigeration because they are lighter, smaller and have fewer moving parts than reciprocating compressors and they are also more reliable. They are more expensive though, so peltier coolers or rotary and reciprocating compressors may be used in applications where cost is the most important or one of the most important factors to consider when designing a refrigeration or air conditioining system.

Play media Borsig steam locomotive type made in From early on, Borsig was a supporter of railroads. The founding date was declared to be 22 July , the day of the first successful casting in the foundry.

Technical drawing of the first steam locomotive Despite tremendous costs, the first locomotive, bearing factory number 1 and the name BORSIG, was finished in This locomotive had an interior frame, a two-axle front pivoted bogie and an extra dead axle behind the only drive axle.

The Borsig locomotive won by 10 minutes, proving that in spite of the lack of experience, Germans could build locomotives that were at least as good as the British models, and so the import of locomotives and engineers was no longer necessary. After this victory, the number of orders rose quickly. A further six machines of this type were sold to the Berlin-Stettiner Eisenbahn and the Oberschlesische Eisenbahn in In the beginning, the Borsig company also built steam engines for their own needs and machines for other companies as well as cast parts for art and construction.

However, the focus soon shifted to locomotive building, and the name Borsig is connected with locomotives to this day. By , railway companies in Prussia had ordered 18 locomotives, and in , Borsig could exhibit his 24th locomotive at the Berlin industrial fair. The one hundredth locomotive was finished in Meanwhile, Borsig built the steam pump for the fountain at Sanssouci and participated in the building of the domes of the Nicolai Church in Potsdam and the Berliner Stadtschloss Berlin City Palace.

The company was expanding rapidly in those years, since new railways were being built all over Germany. In , construction of the new Moabit ironworks started and they became operational in August Borsig was said to be a strict but just boss with a zest for action. For his workers, he set up a sickness fund, a funeral expense fund, and a savings bank. His company had an instruction room, a dining room and a bath with swimming pool.

Borsig steam locomotive used on the Warsaw-Vienna railway Borsig had become sufficiently important by the end of the s that he was able to weather the economic crisis of with little damage. After the th locomotive had been completed in , Borsig was made Geheimer Kommerzienrat Secret Commerce Councillor.

This allowed him to tighten his monopoly position, and 67 of the 68 new Prussian locomotives in came from Borsig factories. However, he could not enjoy his wealth for very long. He died in Berlin on 6 July , at the height of his power.

Further history of the company[ edit ] After the death of August Borsig, the company was led and expanded by his son August Julius Albert Borsig. On the occasion of the completion of the th locomotive, a large celebration with many prominent guests was held, among them the explorer Alexander von Humboldt. At this time, the company that had started out with 50 workers, had employees. It continued its expansion, and moved some part of its production to Zabrze in Silesia in In , Borsig was the largest locomotive producer in Europe.

The company continued to be led mostly by Borsig family members and continued to build large numbers of locomotives, but it began to lose market share to other traffic-related companies. The company moved to Tegel, a former suburb of Berlin. The works was inaugurated in The Tegel works area was one of the most modern facilities in Germany at that time. It had its own harbour where the ships brought the material for the locomotives.

The works itself had long road with every production step at its place. The brand new locomotives left the works through this gate. The company also developed new products that are still part of the current manufacturing program: pressure vessels and compressors. By , the company was on the verge of liquidation , the locomotive business was saved by a merger with AEG. The last of a total of 16, locomotives was built in The rest of the company went to Rheinmetall.

The actual product and service programme of the BORSIG Group consists of pressure vessels, heat exchangers, process gas waste heat recovery systems, quench coolers, scraped surface exchangers, reciprocating compressors for process gases, turbo compressors for process gases, reciprocating compressors for CNG filling stations, blowers and blowers systems, compressor valves, membrane technologies, such as emission control units, vapour recovery systems, gas conditioning, advanced separations, industrial boilers, power plant engineering, power plant services and industrial services.
