Abstract
The invention relates to a vertical submerged pump bearing protection device, which comprises a pump body, a pump cover, a pump shaft, a sealing part, an impeller and a bottom plate, wherein a bearing box body is additionally arranged outside a rolling bearing at the upper end of the pump shaft; the bottom of the bearing box body is connected with a gland in a sealed way to form a sealed oil chamber and a water-cooled cavity at the outer side of the oil chamber; an oil extraction hole is formed in a shaft sleeve body matched with an inner ring of the rolling bearing; one port of the oil extraction hole is communicated with a space between the inner ring and an outer ring of the rolling bearing, and the other port of the oil extraction hole is communicated with the oil chamber, and forms a lubricating oil path together with a through hole in the upper end of the bearing box body; upper, middle and lower heat-preservation cavities of a sliding bearing are additionally formed outside an upper support frame, a support tube and the pump cover respectively, and are communicated through a through hole; a vapor inlet and a vapor outlet are formed in the upper and lower heat-preservation cavities respectively. The device has the characteristics of safe and reliable structure, long service life of the bearings in a pump and the like, the bearings in the pump can work in an ideal environment, and the safe and stable running of pump equipment is ensured.
Description
technical fieldthe present invention relates to a kind of pump inner bearing protective gear, especially a kind of be applicable to carry there is inflammable and explosive, poisonous and harmful, the vertical submerged pump bearing protection device of fusing point high.
background techniqueuse at present such as pumping units such as high temperature liquid sulfur pumps, because this type of pump is operation or stops all in the condition of high temperature, therefore work under bad environment.And there is respectively the structural imperfection such as lubrication, insulation in rolling bearing, sliding bearing in pump, easily cause bearing fault, reduce working life, affect the problems such as the normal smooth running of pumping unit.
summary of the inventionthe object of this invention is to provide a kind ofly for the problems referred to above, can guarantee the vertical submerged pump bearing protection device of rolling bearing in pump, the operation of sliding bearing safety and steady, long service life.
For achieving the above object, vertical submerged pump bearing protection device of the present invention comprises the pump housing, pump cover, pump shaft, sealed member, impeller, base plate, bearing housing is set up in the rolling bearing outside that is wherein positioned at pump shaft upper end, bearing housing bottom is connected to form with gland seal the waterway that seals grease chamber and outside, grease chamber, in the sleeve body coordinating with ring in rolling bearing, offer and carry oilhole, this is carried oilhole one port and is communicated with the space between rolling bearing inner and outer rings, another port is communicated with grease chamber, and forms lubricating oil path with the through hole of bearing housing upper end; In the outside of upper support frame, support tube, pump cover, set up respectively the upper, middle and lower incubation cavity of sliding bearing, and be communicated with by through hole, steam inlet, outlet are opened in respectively upper and lower incubation cavity.
Adopt after said structure, formed lubricating oil path and the water cooling plant of pump shaft upper end rolling bearing, improved the working environment of rolling bearing, guarantee that it uses for a long time.Owing to having set up sliding bearing insulating structure, when outage state or liquid level decline, can prevent that medium crystallization in running clearance is curing, ensure the normal continuous operation of pumping unit.
As a further improvement on the present invention, in grease chamber, be arranged with vertically gear oil jacket in parallel, in the radial clearance of axle sleeve lower end and pump shaft, be provided with oil removal cover.Adopt this structure can stop lubricant oil to rotate, stop oil leakage with axle sleeve.
As of the present invention, further improve, outer wall middle part in grease chamber's is provided with benefit metering jet and is communicated with center region, grease chamber, and gland bottom is provided with drain oil.Adopt accurately oil mass the and in time dregs of fat of collection being emitted in Bu Ce grease chamber of this structure.
The present invention has the features such as structural safety is reliable and stable, pump inner bearing long service life, can make pump inner bearing guarantee steadily normal operation of pumping unit in comparatively ideal working environment.
accompanying drawing explanationfig. 1 is vertical submerged pump bearing protection device overall structure schematic diagram of the present invention.
Fig. 2 is rolling bearing part-structure enlarged view as shown in Figure 1.
Fig. 3 is the insulating structure enlarged view of sliding bearing part as shown in Figure 1.
embodimentbelow in conjunction with accompanying drawing, the present invention is described in further detail:
As Fig. 1, 2, shown in 3, vertical submerged pump bearing protection device of the present invention, comprise the pump housing 1, pump cover 28, pump shaft 2, sealed member 15, impeller 27, the base plate 16 affixed with basis, bearing housing 7 is set up in rolling bearing 4 outsides that are wherein positioned at pump shaft upper end, bearing housing bottom is tightly connected and forms the waterway 9 in sealing grease chamber 8 and outside, grease chamber with gland 12, in the axle sleeve 6 coordinating with ring in rolling bearing, be processed with and carry oilhole 5, this is carried in oilhole one port and rolling bearing, space between outer shroud is communicated with, another port is communicated with grease chamber, and form lubricating oil path with the through hole 3 of bearing housing upper end, in the outside of upper support frame 20, support tube 23, pump cover, increase the upper, middle and lower incubation cavity 18,29,24 that welded closure baffle plate forms sliding bearing 19 respectively, and be connected by through hole 22, the sealing gasket 21 that is positioned at above-mentioned incubation cavity joint can prevent steam leakage.Steam inlet 17, export 25 and be opened in respectively upper and lower incubation cavity.In grease chamber, parallel being provided with kept off oil jacket 10 vertically, and oil removal cover 11 is installed in the radial clearance of axle sleeve lower end and pump shaft.Outer wall middle part, grease chamber is provided with mends the connection of center region, metering jet 13Yu grease chamber, and gland bottom is provided with drain oil 14.When pump turns round, pump shaft impeller rotation, discharges by drain pipe 26 after liquid is pressurized, roller bearings pump shaft, and beat not when guaranteeing that pump shaft rotates, need to arrange a plurality of sliding bearings according to pump shaft length.Owing to outside the increasing of rolling bearing, bearing housing and lubricating oil path and water cooling plant being installed, can be by lubricant oil by carrying oilhole, spray is to rolling bearing, and unnecessary lubricant oil turns back to grease chamber from the through hole of bearing housing upper end, realizes the lubrication and cooling of rolling bearing.Gear oil jacket stops lubricant oil to rotate with bearing housing, and oil removal cover stops oil leakage.Outer wall middle part in grease chamber is provided with mends metering jet and enters center region, grease chamber, and gland bottom is provided with drain oil, accurately in Bu Ce grease chamber oil mass with in time the dregs of fat of collection are emitted.Prevent leakage of oil, oil starvation, repairing inaccurate, the problems such as bearing running hot.By setting up incubation cavity structure in sliding bearing outside, when outage state or liquid level decline, prevent that medium crystallization in running clearance is curing, guarantee the normal continuous operation of pumping unit.
The present invention has the features such as structural safety is reliable and stable, long service life, can guarantee that pump inner bearing is in comparatively ideal working environment, and pumping unit is normal operation steadily.After being applicable to shut down too, structure of the present invention easily solidifies rapidly or the Under Water Pumps such as the bitumenpump of crystallization medium, pump for liquid salts, groove tank pump.
