Abstract

PURPOSE: To prevent breakage of the shaft sealing part, in particular of a seal, and prolong the life of a pump by taking-out the discarge pressure from the vincinity of the discharge port of the pump body, and applying the discharge pressure into the internal chamber of the pump, against the backpressure due to an impeller, holding pressure balance at the shaft sealing part.
CONSTITUTION: A discharge pressure is taken-out from the vicinity of the discharge port 11 of a pump body. In a discharge pressure transmission mechanism 2, the internal chamber of the surging tank 19 equipped with a variable volume body 18 inside is allowed to communicate to a discharge communication pipe 17 and arranged between an oil chamber 13 and the pipe 17. The discharge pressure due to an impeller 4 is transmitted to the oil chamber 13 through the discharge part communicating pipe 17 and the surging tank 19, and the discharge pressure transmitted is offset by the thrust given to the impeller 4 and the shft sealing part 15. As a result, the pressure at the shaft sealing part 15 is balanced, and breakage of the shaft sealing part 15 and decrease of the sealing effect can be prevented, and the transportation pump is able to transport fluid without being subjected to strain continuously at the shaft sealing part.
