Fig. 9.1: Compressed air receiver, horizontal | The compressor builds up a store of compressed air inside the receiver. The compressed air requirement can be covered at intervals from this store. The compressor does not supply compressed air during this time. It is in readiness and does not use electricity. Additionally, fluctuating use of compressed air is compensated for and peak requirements covered. The motor is switched on less often and wear on it reduced.
In some circumstances several receivers are needed to build up an adequate store of compressed air. Very large pneumatic systems usually have an adequate storage capacity. In this case, smaller receivers can be used. |
