Summary of the invention
The purpose of this utility model is to provide a kind of good seal performance, anti abrasive pump with anti-abrasion of particles mechanical seal in order to address the above problem.
The utility model is achieved through the following technical solutions:
A kind of pump is with anti-abrasion of particles mechanical seal, comprise stationary ring, rotating ring and throw-out collar, described stationary ring comprises the first stationary ring and the second stationary ring, described rotating ring comprises the first rotating ring and the second rotating ring, one side of the close inlet end of described the first stationary ring is provided with restrictor ring, the opposite side of described the first stationary ring cooperates with a side of described the first rotating ring, the opposite side of described the first rotating ring is provided with described throw-out collar, one side of described throw-out collar is provided with the rotating ring fitting seat, described the second rotating ring is installed on the described rotating ring fitting seat, one side of described rotating ring fitting seat is provided with on the stationary ring fitting seat, and described the second stationary ring is installed on the described stationary ring fitting seat.
By two pairs of rotating rings and stationary ring are set, and at inlet end restrictor ring is set, mechanical seal Seal cage internal pressure is higher than sealed medium pressure, sealing fluid enters mechanical seal from periphery, reduce the temperature of rubbing surface with cooling means, can effectively reduce between mechanical seal device and the driving shaft to produce friction, the wearing and tearing of less driving shaft have improved the sealability of mechanical seal device.
To be provided with O-ring seals and v-ring between described the first rotating ring and the described throw-out collar as further improvement of the utility model.
That described the second stationary ring is provided with dual-gripper O shape circle as further improvement of the utility model.
Also to be provided with pushing out ring between described throw-out collar and described the first rotating ring as further improvement of the utility model.Between described throw-out collar and described the first rotating ring, pushing out ring is set, is conducive to floating of the first rotating ring.
As preferably, described O-ring seals is O shape rubber ring or tetrafluoro O shape circle.
As preferably, described the first stationary ring and the second stationary ring are ceramic stationary ring or Tungsten carbite stationary ring.
As preferably, described the first rotating ring and the second rotating ring are ceramic rotating ring or Tungsten carbite rotating ring.
By adopting harder stationary ring and the rotating ring of material, because the hardness of the hardness ratio particle of stationary ring and rotating ring is high, can not cause the end face of stationary ring and rotating ring can not wear and tear or plucking.
The beneficial effects of the utility model are:
By two pairs of rotating rings and stationary ring are set, and at the pump shaft inlet end restrictor ring is set, mechanical seal Seal cage internal pressure is higher than sealed medium pressure, sealing fluid enters mechanical seal from periphery, reduce the temperature of rubbing surface with cooling means, can effectively reduce between mechanical seal device and the driving shaft to produce friction, the wearing and tearing of less driving shaft have improved the sealability of mechanical seal device.
