Summary of the invention:
The purpose of this utility model provides a kind of multistage centrifugal pump bearing support bearing support assembly that labyrinth collar is housed, make the bearing support labyrinth collar that is installed at the bearing gland labyrinth collar in the bearing gland and is installed in the bearing support make effective seal, to adapt to and to satisfy needs under the pump shaft work of high temperature, high pressure and high speed rotating to lubricant oil.
The multistage centrifugal pump bearing support bearing support assembly that labyrinth collar is housed, it is made up of pump shaft, bearing gland, seal ring, bearing sleeve, bearing support, bearing gland labyrinth collar, bearing gland connecting bolt, bearing sleeve lock screw, oil thrower, circlip for shaft, bearing support labyrinth collar and bearing, in bearing gland inner ring wall and between the pump shaft outer wall, be set with the bearing gland labyrinth collar, between bearing support madial wall and pump shaft outer wall, be set with the bearing support labyrinth collar; Bearing sleeve is contained on the pump shaft by bearing sleeve lock screw lock sleeve; Bearing outer ring is installed in the bearing support of bearing support, and bearing inner race is installed on outside the bearing sleeve, and has the circlip for shaft that is installed on the bearing sleeve that bearing is made axially locating; On bearing sleeve, be installed with oil thrower; Bearing gland is installed by the bearing gland connecting bolt and is connected the bearing support left end.
The utility model multistage centrifugal pump bearing support is described as follows with the design principle of the bearing support assembly that labyrinth collar is housed:
The oil thrower that is installed on the bearing sleeve rotates under the pump shaft that rotates drives, the lubricant oil of dishing out, parts such as the pump shaft in the bearing support, bearing sleeve and bearing are lubricated, the lubricant oil of being dished out in bearing support is sealed and collects by bearing gland labyrinth collar of installing in the pump shaft left and right sides and bearing support labyrinth collar, thereby makes lubricant oil can continue to obtain lubricated the use in bearing support.
The bearing gland labyrinth collar is columned labyrinth collar, throttling groove, sawtooth and liquid return hole are arranged in the bearing gland labyrinth collar, throttling groove is a trapezoidal cylindric space throttling groove, can make lubricant oil be thrown in the liquid return hole by throwing through throttling groove, the liquid return hole is two adjacent columniform holes, lubricant oil can be back in the bearing support by the liquid return hole.
Bearing support labyrinth collar and bearing gland labyrinth collar structure are identical, the bearing support labyrinth collar is sleeved between bearing support inboard and the pump shaft, and the bearing gland labyrinth collar is sleeved between bearing gland inner ring wall and the pump shaft outer wall.
On the pump shaft left side, have keyway,, be connected with motor output shaft for connecting key is installed; Have some connecting bolt holes on the bearing support right side by installing connecting bolt, bearing support is installed on the inlet segment.
The utility model multistage centrifugal pump bearing support is because bearing gland labyrinth collar and bearing support labyrinth collar have been installed with the advantage of the bearing support assembly that labyrinth collar is housed, in the leakage way of its labyrinth collar, be provided with a plurality of sawtooth and throttling groove, so just increase the resistance in the leakage flow, being sealed under high temperature, high pressure and the high speed like this is effective especially, there is not friction, power consumption is little, and long service life does not need to safeguard.
