| titleOfInvention | Small-flow ultrahigh-pressure boiler feed pump |
| abstract | A small-flow ultrahigh-pressure boiler feed pump belongs to the technical field of boiler feed pumps, and particularly relates to a single-shell, horizontal, multistage, segmental, centrifugal, small-flow (85 m 3/h) and ultrahigh-pressure (18-20 MPa) boiler feed pump. The invention provides a small-flow ultrahigh-pressure boiler feed pump which is convenient to overhaul, safe, stable and reliable to operate. The invention is characterized in that: be provided with sealed letter body and bearing body on the pump shaft at pump body both ends, be mechanical seal in the sealed letter body, its characterized in that: a connecting flange matched with the pump body is arranged outside the sealing box body, and a fixing flange matched with the connecting flange is arranged on the bearing body; an annular cooling groove is formed in the opposite surface of the sealing box body and the pump body, an isolation rib is arranged in the annular cooling groove, and a water inlet and a water outlet which are communicated with the annular cooling groove are formed in the sealing box body and positioned on the two sides of the isolation rib; the inside sealed water hole that is provided with and mechanical seal and the outside intercommunication of sealed letter body of isolation rib. |
