Abstract
The utility model discloses a sliding bearing for a geothermal long shaft deep-well pump, used for exploring geothermal water. The sliding bearing for a geothermal long shaft deep-well pump is characterized in that the inner surface of the sliding bearing for a geothermal long shaft deep-well pump is axially provided with two to six lubricating water tanks 1 whose cross sections are circular arc shaped, a communicating groove 2 whose cross section is also circular arc shaped is provided between each two adjacent lubricating water tanks, and the interior of each lubricating water tank is provided with one to six lubricating holes 3. The length of the sliding bearing for a geothermal long shaft deep-well pump is commonly 20-60 mm. The length of the sliding bearing for a geothermal long shaft deep-well pump has the characteristics of favorable lubricity, reliable use, durability, high-temperature resistance, etc.
Description
The utility model belongs to the improvement of underground heat water pump sliding bearing.
The vertical major axis deep well water pump of underground heat sliding bearing is to guarantee one of critical component that water pump runs well.This technology is to adopt the moulding of rubber expendable mo(u)ld at present, cause the fitted position precision not high, lubrication groove on the bearing inner wall is trapezoid shaped and thermal expansion of self and swelling in addition, working life is generally at 1～2 month in geothermal well, this not only brings difficulty and increases maintenance expenses to use, and brings bigger economic loss sometimes.
The purpose of this utility model is to provide a kind of sliding bearing that is used for the vertical borehole shaft drivenpump of underground heat, and this bearing is owing to have good water lubrication, long service life.
Technical characteristics of the present utility model is that the employing plastics are raw material, and repressed moulding is carried out secondary operations again and made, and has guaranteed the fit dimension precision of bearing and bearing, axle effectively.Key technology of the present utility model is to be that bearing inner wall offers the lubricated tank of axial garden arcuation and be provided with UNICOM's groove of the big helical pitch of garden arcuation between adjacent two lubrication grooves, and offers the perforation aperture that becomes certain inclination angle with axis in every lubrication groove.
Accompanying drawing 1 is a cross sectional view of the present utility model, and accompanying drawing 2 is A-A sectional views of accompanying drawing 1.Wherein 1 is the axially lubricated tank that is opened on the bearing inner surface, its transverse section is that the garden segmental arc by three two radius unequals constitutes the garden arcuation, garden arc radius can adopt 2-6mm and 1-3mm respectively, can offer so lubricated tank 2-6 bar in a bearing.Offer the transverse section and be the big helical pitch UNICOM groove 2 of garden arcuation between two adjacent lubricated tanks, garden arc radius can adopt 1-2mm.Offer lubrication hole 3 in every lubricated tank, can offer 1-6 hole in every groove usually, centerline hole and axis angle are 20-40 °, and the aperture is 2-4mm.The length of whole bearing is generally at 20-60mm.
The characteristics such as the utlity model has fitted position precision height, greasy property is good, uses reliable durable, and is high temperature resistant. It not only can be widely used on the underground heat vertical long deep well water pump, also can be used on the general water pump, also can greatly improve the service life of water pump.
Claims (2)
1, a kind of underground heat borehole shaft drivenpump sliding bearing that is used to exploit geothermal water, it is characterized in that inner surface axial at this bearing offers 2-6 bar transverse section and is the lubricated tank 1 of garden arcuation and offers the transverse section again between adjacent two lubricated tanks and also be the big helical pitch UNICOM groove 2 of garden arcuation and offer 1-6 lubrication hole 3 in every lubricated tank, the length of bearing is generally at 20-60mm.
2, by the said underground heat borehole shaft drivenpump of claim 1 sliding bearing, the transverse section that it is characterized in that lubricated tank is to be that three segmental arcs of 2-6mm and 1-3mm constitute by radius, UNICOM groove transverse section is to be the garden segmental arc formation of 1-2mm with the radius, the center line of each lubrication hole and axis angle are 20-40 °, and the aperture is 2-4mm.
