Systems draining tanks by suction tubes - vary direction or rate of flow by artificially varying direction or cross=section of pipes to eliminate sec. flows also

摘要

A system of suction container with bottom troughs in the base and a suction tube of constant cross-section allows a liquid to be drawn off; the stream of liq. can be diverted by switching over the suction/supply arrangements and/or adjusted by altering the cross-section. The container and tube are both preferably made of polyethylene or polypropylene. ADVANTAGE - Eliminates flows after the container has been emptied. It removes accumulations of liq. (residues and condensates) after the suction process.
