Technical field
The utility model relates to field of metallurgy, in particular to a kind of level Four mechanical pumping system for generating vacuum environment.
Background technique
At present in metallurgy industry, producing vacuum environment main means has two kinds of pumping systems of steam jet pump and mechanical pump.It steams
Vapour jet pump system generally uses Pyatyi series connection of pumps to arrange, in acceptable investment scope, can produce enough suction energy
Power；Steam jet pump operating cost height becomes its serious deficiency, the high-energy source consumption in the preparation process of steam, in life
The pollution for being largely difficult to the sludge cleared up and water is generated during producing；And mechanical pump is mostly three-level mechanical pumping system, but this is
Calorific value of uniting is high, and system fluctuation of service, modular design causes single failure of pump to be affected system.
Utility model content
Utility model is designed to provide a kind of level Four mechanical pumping system for generating vacuum environment, solves single failure of pump
Big problem is influenced on total system.
The utility model is realized in this way a kind of level Four mechanical pumping system for generating vacuum environment, the generation vacuum ring
The level Four mechanical pumping system in border includes: vacuum main valve, passes through the sequentially connected bag-type dust filtering of pipeline with the vacuum main valve
The rear and front end of device, primary pump, two stage pump, triplex and four-stage pump, every grade of pump is equipped with blocking valve.
The further technical solution of the utility model is: the quantity of the bag-type dust filter is 4.
The further technical solution of the utility model is: every grade of pump is equipped with by-pass line.
The further technical solution of the utility model is: the triplex is lobe pump.
The further technical solution of the utility model is: the four-stage pump is screw pump.
The utility model has the beneficial effects that the novel level Four mechanical pumping system of this hair, reduces energy consumption, operating cost is reduced, is mentioned
High system stability reduces influence of single failure of pump to system, so that mechanical pumping system is reliably applied to very much steel plant severe
Under environment in existing technique；This level Four pumping system can significantly shorten the pumpdown time, to improve yield, be preheated by reducing
Time reduces production cost, and improves the quality of production by sufficient guarantor's vacuum time；Pump group efficiency is improved, and efficiency value mentions
The service life that can extend pump is risen, reduces the usage amount of pump, and reduce the one-time investment and operating cost of client；Extend
The service life of pump will run to protect pump at a lower temperature using the vacuum system of level Four mechanical pump；It is excellent
Change the compression ratio between every grade of pump, to improve the efficiency of system and reduce calorific value.
Detailed description of the invention
Fig. 1 is a kind of overall structure signal of level Four mechanical pumping system for generating vacuum environment provided by the utility model
Figure.
Appended drawing reference: 2, vacuum main valve 3, bag-type dust filter 4, primary pump 5, two stage pump 6, triplex 7, driver pump 8,
By-pass line 9 blocks valve.
Specific embodiment
Embodiment one: Fig. 1 show it is a kind of generate vacuum environment level Four mechanical pumping system, the four of the generation vacuum environment
Grade mechanical pumping system include: vacuum main valve 2, with the vacuum main valve 2 by the sequentially connected bag-type dust filter 3 of pipeline,
Primary pump 4, two stage pump 5, triplex 6 and four-stage pump 7, the rear and front end of every grade of pump, which is equipped with, blocks valve 9；It is described
The quantity of bag-type dust filter 3 is 4；Every grade of pump is equipped with by-pass line 8；The triplex 6 is lobe pump；It is described
Four-stage pump 7 is screw pump, and the novel level Four mechanical pumping system of this hair reduces energy consumption, reduces operating cost, improves system stability.
Influence of single failure of pump to system is reduced, mechanical pumping system is made reliably to be applied to very much existing work under steel plant's adverse circumstances
In skill；This level Four pumping system can significantly shorten the pumpdown time, to improve yield, be produced by reducing preheating time reduction
This, and the quality of production is improved by sufficient guarantor's vacuum time；Pump group efficiency is improved, and the promotion of efficiency value can extend pump
Service life, reduces the usage amount of pump, and reduces the one-time investment and operating cost of client；Extend the service life of pump:
It will run to protect pump at a lower temperature using the vacuum system of level Four mechanical pump；Optimize between every grade of pump
Compression ratio, to improve the efficiency of system and reduce calorific value.
When work: exhaust gas removes chalk dust removing by filter into four bag-type dust filters 3 by vacuum main valve 2
Exhaust gas, into 4 system of primary pump, behind sequentially enter two, three, four-stage pump, be most discharged into atmosphere through tip tube road afterwards.In each pump
Front and back, which is equipped with, blocks valve 9, when breaking down to prevent from individually pumping, can close front and back valve, by pump extraction maintenance, without shadow
The operation for ringing whole system, is equipped with by-pass line 8 in every primary pump, and when this grade pump does not start, pump front and back valve is closed, other
Valve of threading a pipe is opened, and gas passes through through by-pass line 8.The pump of the third level 6 is using can the Roots that is gas-cooled with pre-admission of direct-connected atmosphere
Pump, rear heat exchanger can carry out cooling down to the exhaust gas that triplex 6 comes out, and exhaust gas section after cooling is back to three-level
Pump 6, to cool down to the pump housing.For four-stage pump 7 using the screw pump that can bear High Pressure Difference, tail end connects atmosphere, and by exhaust gas
It is discharged into atmosphere, all pumping systems are all positioned in ventilation, noise reduction process.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
