Abstract:
A water hammer cleaning machine comprising:a cleaning liquid supply piping line (P2) composed of a closed circuit in order for cleaning liquid to be circulated selectively between a cleaning liquid tank (40) and a cleanable piping line (P4) as well as provided with a pump (30) to give pressure to said cleaning liquid, an air piping line (P1), on an end portion of which is installed an air compressor (10) and the other end portion of which is connectd selectively to said cleaning liquid tank (40) and the cleaning liquid supply piping line (P2) connecting with the cleanable piping line (P4), an automatic opening-closing valve (Vm) being provided on said air piping line (P1) and being handled automatically selectively between the first position closing said air piping line (P1) and the second position opening said air piping line (P1), a water hammer device (20) provided between said air compressor (10) and said automatic opening-closing valve (Vm), and intermitting the compressed air, which is spurted from said air compressor (10) according to the pre-set value in case that said automatic opening-closing valve (Vm) is regulated to the second position, to flow periodically or non-periodically into said air piping line (P1), and a control means provided to control said automatic opening-closing valve (Vm), said water hammer device (20) and other valves selectively according to the pre-set work-process.
