Benefits of technology

[0007]In view of the disadvantages in the prior art, it is an object of the present invention to provide a multi-stage compressing apparatus in which an operation control system is simplified, its cost is reduced and safety is improved.

Problems solved by technology

So the secondary gas compressor 102 is loaded excessively and is liable to be out of order.
The whole apparatus becomes not only more complicate, but also high cost for manufacturing it.

second embodiment

[0018]FIG. 2 is a block diagram of a multi-stage gas compressing apparatus according to the present invention.

[0019]A relief valve 11 is provided at a conduit 10 between a primary gas compressor 8 and a secondary gas compressor 9. If the secondary gas compressor 9 is out of order or does not work, the primary gas compressor 8 will have to compress a gas to substantially the same pressure that the secondary gas compressor 9 could achieve compression. So the primary gas compressor 8 would be subjected to excessive load and would be broken. To avoid such situation, gas that flows through the conduit 10 is released to air by opening the relief valve 11, if gas pressure reaches an upper limit such as 0.75 MPa.

third embodiment

[0020]In the third embodiment in FIG. 3, instead of the relief valve 11, at the conduit 10 between the primary gas compressor 8 and the secondary gas compressor 9, an intermediate control device 12 is provided and comprises a pressure sensor 13 and a micro computer circuit 14. In the intermediate control device 12, upper limit pressure and lower limit pressure are set. A pressure switch may be used instead of the pressure sensor 13. The pressure sensor 13 detects pressure of gas through flowing the conduit 10 and actuates the microcomputer circuit 14 connected to the pressure sensor 13 electrically.

[0021]In FIG. 3, if the secondary gas compressor 9 is out of order or does not work, the primary gas compressor 8 will have to compress gas to substantially the same pressure that the secondary gas compressor 9 could achieve compression. The primary gas compressor 8 would be subjected to excessive load and would be broken. To avoid such situation, if the pressure sensor 13 detects an uppe...

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

BACKGROUND OF THE INVENTION[0001]The present invention relates to a multi-stage gas compressing apparatus for compressing a compressed gas by a plurality of compressors, and particularly relates to a multi-stage gas compressing apparatus for simplifying operation of a primary gas compressor and a secondary gas compressor.[0002]In FIG. 5, a conventional gas compressor comprises a low-pressure primary gas compressor 101 such as a scroll compressor for compressing a compressed gas, and a high-pressure secondary gas compressor 102 or booster compressor such as a reciprocating compressor for further compressing gas compressed by the scroll compressor 101. High pressure gas compressed by the secondary gas compressor 102 is stored in a storage tank 103.[0003]To control operation of the compressors, pressure sensors 104,105 for setting upper-limit pressure and lower-limit pressure respectively are provided to the gas compressors 101,102 respectively. Based on the upper-limit pressure and lo...
