Background technique
1999-2000 in the air compressor plant in certain chemical plant, there are five L-type reciprocal compressors, two W type reciprocal compressors, air compression system is after driving, produce associating damaging vibration, abnormally dangerous, two W type reciprocal compressors are removed, go up again a centrifugal compressor, standby host using five L-type reciprocal compressors as centrifugal compressor, through technological improvement, since within 2002, driving, no matter be single opening L-shaped reciprocal compressor, still singly drive centrifugal compressor, whole air compression system does not all produce associating damaging vibration, do not produce local failure vibration yet, it is very steady that compression system turns round.Even to this day system turns round very normally.
Centrifugal air compressor is that a kind of high speed rotary formula equipment, air displacement are large, exhaust pressure fluctuation is less, but the adjusting of air displacement and exhaust pressure is more complicated.
In the middle of the engineering of centrifugal type air compression system, surge vibration, noise problem, occur often.Even if the centrifugal type air compression system running well, if gas consumption increases suddenly or reduces, all can produce surge, cause whole air compression system to produce associating damaging vibration, cause pipeline damaged, equipment damage, so that lead to production accident.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of compressed air system of centrifugal air compressor is provided.
No matter the compressor of which kind of form, also wants suitable setting pipeline, needs suitable pipeline to arrange and suitable setting pipe support, just can make whole air compression system without associating damaging vibration, vibrates the optimum air compression system of smooth running without local failure.
Based on the moving air compression system of centrifugal air compressor vibration damping, it is characterized in that, centrifugal air compressor air inlet, adopts horn shape suction port, and suction port position exceeds roof, adds silencing apparatus and rainhat on suction port.
Admission line is provided with silencing apparatus, and arranging of admission line pipeline is short and straight.
When admission line is turned, radius of turn is of a size of pipeline nominal diameter 2.5-3 doubly.
Centrifugal air compressor exports to the pipeline between automatic regulating valve, adopts lineal shape Connecting format, and automatic regulating valve is between gas-liquid separator, the pipeline layout of will turning.
When admission line is turned, pipeline turning radius size is 1.5 times of pipeline nominal diameters.
Admission line end is provided with reducer between centrifugal air compressor, and the length of reducer is greater than reducer Outside diameter, and the resistance drop causing to reduce reducer prevents the sudden enlargement of pipeline and dwindles suddenly the vibration that causes pipeline.
Reducer is connected with silencing apparatus, and silencing apparatus is connected with centrifugal air compressor, and centrifugal air compressor outlet is provided with safety valve, centrifugal air compressor outlet is provided with atmospheric valve, atmospheric valve top is provided with silencing apparatus and tarpaulin, and pipeline requires to be connected to outside factory building, and drain is higher than roof.
Centrifugal air compressor outlet is connected with outlet conduit, outlet conduit is provided with automatic regulating valve, when gas consumption increases suddenly or reduces, can be used for regulating air demand by automatic regulating valve, prevents centrifuge surge, cause the associating damaging vibration of whole air supply system, cause security incident.
Outlet conduit is connected with gas-liquid separator, and when outlet conduit is turned, radius of turn is of a size of 1.5 times of pipeline nominal diameters.
Gas-liquid separator outer pipe is connected to gas tank, and gas tank is provided with air supply header, and air supply header carries out air feed to outside.
The utility model has the advantage of, for production system provides stable without surge, without associating damaging vibration, without local failure vibration, low noise compressed air system stably.
