Abstract
A multi-stage gas compressing apparatus comprises a primary gas compressor and a secondary gas compressor. A gas compressed in the primary gas compressor is transferred to the secondary gas compressor in which the gas is further compressed. A detector detects upper and lower limits of discharge pressure from the secondary gas compressor, and a signal is sent from the detector to a control device connected to the primary and secondary gas compressors. Then, the primary and secondary gas compressors are started or stopped by the control device.
Description
Technical field
[0001] the present invention relates to a kind of multistaging gas compression device, relate to a kind of multistaging gas compression device of having simplified gas compressor and secondary air compressor operation specifically by the compressed gas of a plurality of compressor compresses.
Background technique
[0002] as shown in Figure 5, traditional gas compressor comprises a gas compressor 101 of low pressure that is compressed the scroll compressor of gas such as compression, the high-voltage secondary gas compressor 102 that is compressed gas that was compressed by scroll compressor 101 with further compression is perhaps such as the booster compressor of reciprocal compressor.Pressurized gas by 102 compressions of secondary air compressor are stored in the storage tank 103.
[0003] in order to control the operation of compressor, the pressure transducer 104 and 105 of capping pressure and threshold pression offers gas compressor 101 and 102 respectively respectively.The upper limit pressure and the threshold pression of the outlet pressure that detects respectively based on pressure transducer 104 and 105, gas compressor 101 and secondary air compressor 102 begin independently and stop by control apparatus 106 and 107.
[0004] yet, in multistaging gas compression device,, need provide two pressure transducers 104,105 and control apparatus 106,107 in the control gaseous compressor 101 and 102 independently each.And in order to adjust load, receiving tank 108 has to be arranged between gas compressor 101 and the secondary air compressor 102.
Especially, if a gas compressor 101 stops, having only 102 operations of secondary air compressor.The load of secondary air compressor 102 exceeds the quata and malfunction easily like this.
Whole device is not only more complicated, and manufacture cost is high.
Summary of the invention
[0005] consider the shortcoming of technology formerly, an object of the present invention is to provide a kind of multistage compression device, its operation control system is simplified, and reduces cost, and increases Security.

[0007] Fig. 2 is its second embodiment's a skeleton diagram;
[0008] Fig. 3 is the 3rd embodiment's of gas compressor work for once a skeleton diagram;
[0009] Fig. 4 is the skeleton diagram as idle the 3rd embodiment of gas compressor; With
[0010] Fig. 5 is the skeleton diagram of traditional multistaging gas compression device.
Embodiment
[0011] as shown in Figure 1, multistaging gas compression device according to the present invention comprises gas compressor 1 or lower scroll formula compressor, is used to compress compressed gas; With secondary air compressor 3 or high pressure reciprocal compressor, be used for further compressing compressed gas, link to each other with a gas compressor 1 by pipeline 2.
The compressed gas storage of the high pressure by secondary air compressor 3 compression is in storage tank 5, and described storage tank 5 links to each other with secondary air compressor 3 by pipeline 4.
[0012] pressure transducer 6 is set to storage tank 5 to survey the head pressure by the pressurized gas of secondary air compressor 3 compressions.Pressure transducer 6 is set at when 1.0MPa upper limit pressure and cuts out, and 0.8MPa opens during threshold pression.
When pressure transducer 6 detected upper limit pressure, it passed to the signal of control apparatus 7 " pass ", and the signal that described control apparatus 7 will be used to stop to send to gas compressor 1 and secondary air compressor 3 so that they stop simultaneously.
Air in the storage tank 5 is consumed, and pressure transducer 6 detection limit pressure.The signal of " opening " sends to control apparatus 7 from pressure transducer 6, and the signal that described control apparatus 7 will be used to begin sends to gas compressor 1 and secondary air compressor 3 so that they begin simultaneously.
[0013] Fig. 2 is the skeleton diagram according to second embodiment of multistaging gas compression device of the present invention.
[0014] safety valve 11 is arranged on the pipeline 10 between gas compressor 8 and the secondary air compressor 9.If secondary air compressor 9 is worked undesired or do not worked, No. one time gas compressor 8 have to reach the roughly the same pressure that should finish compression with secondary air compressor 9 by pressurized gas.So No. one time gas compressor 8 may be subjected to overburdening and damage.For fear of this situation, if gas pressure reaches the upper limit such as 0.75MPa, the gas that flows through pipeline 10 11 is discharged in the air by opening the safety-valve.
[0015] as shown in Figure 3, in the 3rd embodiment, be to substitute safety valve 11, on the pipeline 10 between gas compressor 8 and the secondary air compressor 9, be provided with the neutral-controlled plant 12 that includes pressure transducer 13 and micro-computer circuit 14.Upper limit pressure and threshold pression in neutral-controlled plant 12, have been set.Pressure switch can be used for replacing pressure transducer 13.The gas pressure of pressure transducer 13 detection flows pipings 10, and driving and pressure transducer 13 electricity micro-computer circuit 14 in succession.
[0016] as shown in Figure 3, if secondary air compressor 9 is worked undesired or do not worked, No. one time gas compressor 8 have to reach the roughly the same pressure that should finish compression with secondary air compressor 9 by pressurized gas.No. one time gas compressor 8 may be subjected to overburdening and damage.For fear of this situation, if pressure transducer 13 detects the upper limit pressure such as 0.75MPa, micro-computer circuit 14 will transmit a signal to 8, gas compressors 8 of a gas compressor will be stopped.
[0017] as shown in Figure 4, if 8 work of gas compressor are undesired or can not work, secondary air compressor 9 may be subjected to overburdening and damage.For fear of this situation, if pressure transducer 13 detects the threshold pression such as 0.5MPa, micro-computer circuit 14 will transmit signal and give secondary air compressor 9, and secondary air compressor 9 will stop.
[0018] scope between the upper and lower bound pressure that detects of safety valve 11 or the control apparatus 12 that increases is provided with to such an extent that the scope between the upper and lower bound pressure that detects than the pressure transducer 5 that is connected on the storage tank 5 is lower.If not like this, gas compressor or secondary air compressor may work undesired.
[0019] above-mentioned only relevant with embodiments of the invention.Under the situation of the scope that does not deviate from claim, those of ordinary skills can make multiple variation and modification.
