The utility model discloses a characteristics are: simple structure, installation, easy maintenance effectively protect pump shaft, slide bearing, make it when abominable transport contains solid particle or special corrosive medium, during pump shaft and slide bearing can be in cleaning medium, extension pump shaft, slide bearing's life, the safe and stable operation of guarantee pump.
Description
Technical field
This utility model relates to a kind of vertical submerged pump, a kind of for carrying containing certain solid particle, the vertical pump of corrosive liquids.
Background technology
At present; for carrying various cleaning, having the center of a small amount of solid particle or the liquid that is corrosive to go out to flow vertical submerged pump; pumped (conveying) medium is by a stay tube; contacting with pump shaft and sliding bearing, when containing solid particle in some media or be corrosive, easily there are the situations such as corrosion, wear in pump shaft and sliding bearing; serious curtailment pump shaft and the service life of sliding bearing; once pump shaft or sliding bearing damage, and the friction pair parts of pump will be the most impaired, affect the properly functioning of pump.
Summary of the invention
The purpose of this utility model is to provide the pump shaft of a kind of vertical submerged pump and sliding bearing protection device; effective insulation blocking pump shaft and sliding bearing when conveying contains solid particle or has special Korrosionsmedium, it is ensured that pump is in the normal even running of bad working environments.
For reaching above-mentioned purpose; the technical solution adopted in the utility model is: propose pump shaft and the sliding bearing protection device of vertical submerged pump; including outlet section, blower inlet casing, a stay tube, intermediate support beam, impeller, pump shaft, parts of bearings and seal member; pump shaft pillar it is provided with outside pump shaft; pump shaft pillar is between pump shaft and a stay tube; and the sliding bearing being installed on pump shaft is positioned at pump shaft pillar; described pump shaft pillar is fixed between seal member and blower inlet casing, and the upper port of pump shaft pillar connects with annular seal space.
It is provided with sealing ring between upper port and the seal member of described pump shaft pillar, between lower port and the blower inlet casing of pump shaft pillar, is provided with sealing ring.
Described pump shaft pillar uses some intermediate support beams to be fixed between seal member and blower inlet casing, and intermediate support beam is distributed along the axially spaced-apart of pump shaft pillar, and the bottom of pump shaft pillar is fixing with blower inlet casing to be connected.
This utility model is provided with inside pump shaft pillar, and pump shaft pillar the cleaning medium of pressure medium in being connected with higher than a stay tube between pump shaft outside and a stay tube, is effectively isolated pump shaft and sliding bearing and pumped medium.After using said structure; owing to sliding bearing is immersed in the cleaning medium higher than external agency pressure; the granule being prevented effectively from medium or Special Corrosion liquid are to pump shaft and the damage of sliding bearing; preferably protection pump shaft and plain bearing element; extend the service life of pump, it is ensured that the safety and steady of pump runs.
Feature of the present utility model is: simple in construction; installation, maintenance is convenient; effectively protect pump shaft, sliding bearing; make it when severe conveying contains the medium of solid particle or Special Corrosion; pump shaft and sliding bearing are in cleaning medium; extend pump shaft, the service life of sliding bearing, ensure that the safety and steady of pump runs.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
The pump shaft of vertical submerged pump as shown in Figure 1 and sliding bearing protection device, including parts of bearings 1, seal member 2, outlet section 3, stay tube 4, pump shaft pillar 5, pump shaft 6, intermediate support beam 7, sliding bearing 8, blower inlet casing 9, impeller 10, suction casing 11.It is provided with pump shaft pillar 5 in pump shaft 6 outer cover, pump shaft pillar 5 is between pump shaft 6 and a stay tube 4, and the sliding bearing 8 being installed on pump shaft 6 is positioned at pump shaft pillar 5, pump shaft pillar 5 is fixed between seal member 2 and blower inlet casing 9, it is provided with sealing ring between upper port and the seal member 2 of pump shaft pillar 5, being provided with sealing ring between lower port and the blower inlet casing 9 of pump shaft pillar 5, the upper port of pump shaft pillar 5 connects with annular seal space.
Pump shaft pillar 5 uses and some is fixed on intermediate support beam 7 between seal member 2 and blower inlet casing 9, and intermediate support beam 7 is distributed along the axially spaced-apart of pump shaft pillar 5, and the bottom of pump shaft pillar 5 is fixed with blower inlet casing 9 and is connected.
Pump shaft pillar 5 with sealing ring plays the effect of separate pump pumped (conveying) medium and cleaning medium, pump shaft 6 and sliding bearing 8 inside pump shaft pillar 5, does not contacts with pumped medium.Pumped medium is in a flowing between stay tube 4 and pump shaft pillar 5.The cleaning medium higher than pumped medium pressure being passed through in annular seal space flows through blower inlet casing 9 and the impeller 10 of pump by pump shaft pillar 5, flows directly to the entrance of pump from impeller 10 balance pipe, is effectively isolated protection pump shaft and sliding bearing.
This utility model has simple in construction; installation, maintenance is convenient, effectively protects pump shaft, sliding bearing so that it is be in cleaning medium when conveying is containing solid particle or Special Corrosion medium; extend pump shaft, the service life of sliding bearing, ensure that the safety and steady of pump runs.
