Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
Detailed narration is made to the structural principle and operation principle of the present invention below in conjunction with the accompanying drawings.
As shown in Figure 1：Including B1 pumps 1；B2 pumps 2；C1 condensers 3；Stop valve 1；Stop valve 25；S4 stop valves 36；
Stop valve 47；S3-1 pumps 8；S3-2 pumps 9；C2 condensers 10；S4-1 pumps 11；S4-2 pumps 12；C3 condensers 13；Described cut-out
Valve 1 is arranged between C1 condensers 3 and S3-2 pumps 9；Described stop valve 25 be arranged on C1 condensers 3 and S3-1 pumps 8 it
Between；Described S4 stop valves 36 are arranged between C2 condensers 10 and S4a-1 pumps 11；It is cold that described stop valve 47 is arranged on C2
Between condenser 10 and S4b-2 pumps 12.Wherein stop valve 25 is the increased valve in former vacuum pump system building form, is also
The key point of the present invention.
The mode of operation of vacuum pump system refers to table 2《Vavuum pump mode of operation is selected》；The operational mode of vavuum pump is still
According to table 1《The operation signal of vavuum pump mode of operation》Perform.
Embodiment 1, when processing steel grade is not required the speed of evacuation, it is only necessary to general light processing is carried out to molten steel, now
The selection mode of ejector stage pump (S3, S4) is with reference to " the pattern 1 " in table 2.
Embodiment 2, when handling the larger steel grade of the discharge quantity such as ultra-low-carbon steel, it is necessary to carry out deep decarburization, now ejector stage pump
The selection mode of (S3, S4) is with reference to " the pattern 2 " in table 2.
Embodiment 3, when the failure of ejector stage pump (S3, S4) some pump, or vacuum system leak rate are excessive, now sprays
The selection mode of level pump (S3, S4) is with reference to " pattern 3 " or " pattern 4 " in table 2.
The operation principle of the present invention：
Application claims need the exhaust capacity of deployed jet pump in design calculation stages.Calculating exhaust capacity and steam
During consumption, jet pump S3-1 pumps 8, S4-1 pumps 11 are smaller compared to S3-2 pumps 9, S4-2 pumps 12, mainly based on matched with pressurization pump；And
S3-2 pumps 9, S4-2 pumps 12 are main to shorten based on pumpdown time, therefore exhaust capacity and the steam consumption can be than larger.It can thus be concluded that, very
" the mode of operation meeting steam saving consumption of pattern 1 ", relative motion cost is relatively low for empty pumping system selection；And " the selection of pattern 2 "
Stress the operating efficiency of vavuum pump, in the processing steel grade that discharge quantity is larger, processing time is longer, although the unit vapour of vavuum pump
Consumption is larger, but shortens total processing time, has equally saved steam consumption quantity on the premise of metallurgical index is ensured, has reached saving
The effect of cost.As for " pattern 3, pattern 4, pattern 5 " are set only for special (accident) situation, it is therefore an objective to ensure production section
Play, it is to avoid unnecessary accident and loss.In a word, increased between the entrance of jet pump S3-1 pumps 8 cut is exported in C1 condensers 3
Disconnected valve 25, can make the operational mode change of vacuum pump system various, more adapt to production requirement.And disappear with steam is reduced
The effect of consumption, reaches the function of energy saving and cost lowering.
The operation signal of the vavuum pump mode of operation of table 1
The vavuum pump mode of operation of table 2 is selected
