Abstract
PURPOSE: To make possible stable automatic operation of a pump for a small-sized pressure tank by such a construction that the lower opening of the priming line in the pressure tank at the upper part of the pump is situated below the upper opening of the drainage line.
CONSTITUTION: At the time of self-suction operation, prime water poured from the prime water intake 14 fills the inside of the casing 5 etc. situated below the upper opening of the drainage line 18. When self-suction operation is started, the air in the suction tube 9 is taken into the casing 5 and transported to the discharge side 11 in the form of bubbles, and then accumulated afloat in the pressure tank 3, giving an effect of increasing the effective utilization capacity at the time of automatic operation. The water which has taken off the air, descends again into the casing 5 to repeat self-suction action. Then, when pumping operation is commenced it rises up through the priming line 16 from the gap 23 and further supplied through the upper opening 19, the drainage line 18 and the discharge opening 17. An air quantity which makes possible stable automatic operation due to the position of the openings 19, 21 can be accumulated in the tank 3.
