In conclusion, an oil seal and mechanical sealing structure is adopted in the mechanical sealing sand pump, the sealing performance of the sand pump is guaranteed through double sealing, and the mechanical sealing sand pump is simple in mechanical sealing structure and convenient to replace, and saves time.
Description
Technical field
The present invention relates to a kind of oil exploration equipment, be specifically related to a kind of mechanical seal sand pump.
Background technique
Sand pump is that device provides power for the sand remover in Solids control for drilling fluids equipment, desilter, eddy flow be with slurry etc., and sand pump can inject these cyclone separators with certain pressure by the drilling fluid that contains solid phase particles, to isolate solid phase particles.Due to the continuous operation tens days usually of sand pump in drilling process, and the working medium mud that sand pump is carried contains corrosive material, and temperature is higher, contains the hard material such as a large amount of grit simultaneously, easily causes the wearing and tearing of sand pump each several part; Due to the sand pump load that withstands shocks simultaneously, vibrate comparatively seriously, therefore also easily there is the situation of leaking.On the main shaft of existing sand pump, be generally impeller, tamp seal arrangement, the structure of bearing, the sealing of tamping that this sand pump adopts is to seal by the jam-packed power between packing and rotating shaft, thereby the friction power loss of pump is large, gravel in on-stream drilling fluid is easy to get between packing and rotating shaft, make the two very quick-wearing, tamp the life-span of sealing and generally only have about one week.After heavy wear, just there will be leakage, pump pressure declines, and the desanding effect of equipment is degenerated.In addition, this centrifugal sand pump bearing bracket is near the one side of impeller owing to being directly subject to telling the impact wear of gravel in the drilling fluid of motion, and its gap can increase rapidly, and the service behaviour of pump also constantly declines, and causes sand pump needs thoroughly to keep in repair.
Summary of the invention
The present invention aims to provide a kind of mechanical seal sand pump, and this sand pump adopts the structure of oil sealing and mechanical seal, and double seal has guaranteed the sealing of sand pump, and mechanical seal structure is simple simultaneously, changes convenient and time-saving.
Technological scheme of the present invention is as follows: a kind of mechanical seal sand pump, comprise the pump housing, main shaft, impeller, mechanical seal device, oil-sealing arrangement, bearing pack, described main shaft is connected with the pump housing by bearing pack, the pump housing of described bearing pack top is provided with oil hole, described oil-sealing arrangement is installed on the main shaft between bearing pack and impeller, described mechanical seal device is installed on the main shaft between oil-sealing arrangement and bearing pack, the pump housing of described mechanical seal device top is provided with oil hole, described oil-sealing arrangement comprises oil seal cover and oil sealing, described oil seal cover is placed on oil sealing outside, contact with mechanical seal device.
Described mechanical seal device comprises boards, rotating ring, stationary ring, spring, spring seat; Described boards is fixedly connected with the pump housing, and contact with the outside of rotating ring, stationary ring, described rotating ring and impeller interlock, described stationary ring contacts with rotating ring under the support of spring, the described spring the other end is fixedly connected with spring seat, and the described spring seat the other end contacts with oil seal cover.
Described bearing pack comprises bearing, bearing enclosure, bearing cap, and described bearing is provided with two, and the space between bearing is made as oil pocket, and bearing enclosure is connected with bearing, is positioned at oil pocket outside, and bearing enclosure outside is provided with bearing cap.
The present invention adopts the double sealing structure of oil sealing and mechanical seal, the mechanisms such as the rotating ring of mechanical seal structure, stationary ring and spring are placed among fluid, surface of contact boards, rotating ring and stationary ring three forms sealing surface oil film, increased film area, effectively prevented that drilling fluid from entering seal arrangement; Simultaneously, during rotating ring rotation, its drilling fluid around is outwards got rid of, make solid phase particles wherein be difficult to enter the sealing surface of laminating, and lubricant oil is under the formed fluid dynamic effect of disalignment of centrifugal force and dynamic and static ring, constantly enter sealing surface, as long as have enough lubricant oil in oil pocket, sealing surface just can well be lubricated, and guarantees that mechanical seal normally moves; Mechanical seal device opposite side is also provided with oil-sealing arrangement, and sand pump is formed to the second resealing protection, makes mechanical seal device because the micro-leakage that long-time running occurs is unlikely to affect the running of main shaft, thereby guarantees the good running of whole sand pump.
In sum, mechanical seal sand pump of the present invention adopts the structure of oil sealing and mechanical seal, and double seal has guaranteed the sealing of sand pump, and mechanical seal structure is simple simultaneously, changes convenient and time-saving.
