Abstract
The utility model relates to a guide bearing sandproof device on a submersible electric pump, which comprises a submersible pump, an upper guide bearing, a filter and a filtering layer arranged on an upper diversion shell above a pump shaft of the submersible pump. The top part of the pump shaft of the submersible pump is provided with a circulation channel and drain holes, one end of the circulation waterway is led to the top end of the pump shaft, and the other end is communicated with the drain holes which are communicated with the outer side of the pump shaft; a water chamber is arranged on the outer side of the pump shaft corresponding to the drain holes; a pump shaft above the drain holes or the circulation channel is sheathed with an oil seal box which is fixedly arranged on the upper diversion shell, and a framework oil seal is arranged in the oil seal box. The utility model has the advantages of simple structure, good sandproof effect and long service life; pump shaft power can not be affected.
Description
The utility model belongs to the anti-silt particle device of a kind of Submerged Motor Pumps top guide bearing.
At present, the QJ submersible pump of well pump industry production is to manufacture and design according to the service condition among the GB GB/T2817-91, and it is relatively stricter to requirements in water quality, " content of solid matter is not more than 0.01% in the water ", but, in actual use, especially for new well, before filter does not form, after water pump started, a large amount of silt particles entered in the pump, made the rotatable parts of Submerged Motor Pumps easily frayed, particularly top guide bearing and pump shaft are subjected to silt particle destruction, thereby influence the working life of complete machine.
The patent No. is 93214525.6 to disclose a kind of silt-proof submersible pump, and it comprises submersible pump, and the top guide bearing of submersible pump, filter and filter layer are installed on the last blower inlet casing of pump shaft top of submersible pump; Though it has certain filtration to silt particle, lubrication effect is not good, causes top guide bearing and pump shaft to be killed easily, and top guide bearing and pump shaft are damaged, thereby influences the working life of complete machine.
The purpose of this utility model is to address the above problem, provide a kind of simple in structure, compact, do not influence pump shaft power, the anti-silt particle device of anti-silt particle Submerged Motor Pumps top guide bearing effective, long service life.
The utility model comprises submersible pump, top guide bearing, filter and filter layer are installed on the last blower inlet casing of pump shaft top of submersible pump, circulation water channel and weep hole are arranged at the pump shaft top at submersible pump, circulation water channel one end pass-out pump shaft top, and the other end communicates with weep hole, weep hole communicates with the pump shaft outside, with the corresponding pump shaft of the weep hole outside hydroecium is arranged; Be set with the oil sealing box on the pump shaft below weep hole or the circulation water channel, and the oil sealing box is fixedly mounted on the blower inlet casing, outside framework oil seal is installed in the oil sealing box.
The utility model is simple in structure, compact, do not influence pump shaft power, anti-effective, the long service life of silt particle.
Accompanying drawing is the structural representation of the utility model most preferred embodiment;
Among the figure: 1. filter, 2. filter layer, 3. top guide bearing, 4. circulation water channel, 5. oil sealing box, 6. outside framework oil seal, 7. taper sheath, 8. impeller is 9. gone up blower inlet casing, 10. pump shaft, 11. hydroeciums, 12, submersible pump, 14. weep holes.
Below in conjunction with most preferred embodiment and accompanying drawing the utility model is described in detail:
As shown in drawings, the utility model comprises submersible pump 12, top guide bearing 3, filter 1 and filter layer 2 are installed on the last blower inlet casing 9 of pump shaft 10 tops of submersible pump 12, circulation water channel 4 and weep hole 14 are arranged at pump shaft 10 tops at submersible pump 12, circulation water channel 4 one end pass-out pump shafts 10 tops, and the other end communicates with weep hole 14, and weep hole 14 communicates with pump shaft 10 outsides, with weep hole 14 corresponding pump shafts 10 outsides hydroecium 11 is arranged.
During use, water enters circulation water channel 4 through filter 1 and filter layer 2, after submersible pump work, pump shaft 10 begins rotation, and under action of centrifugal force, the water in the circulation water channel 4 is thrown out of through weep hole 14 and goes forward side by side into hydroecium 11, and the water in the hydroecium 11 is the top of tank pump shaft 10 and enters circulating water road 4 along the oil groove on the top guide bearing 3, thereby form good lubricating, make top guide bearing and pump shaft be difficult for being damaged, thereby prolonged the working life of complete machine.
In order further to improve anti-silt particle effect, as shown in drawings, on the pump shaft 10 below weep hole 14 or the circulation water channel 4, be set with oil sealing box 5, and oil sealing box 5 is fixedly mounted on the blower inlet casing 9, outside framework oil seal 6 is installed in the oil sealing box 5.
Claims (2)
1, the anti-silt particle device of a kind of Submerged Motor Pumps top guide bearing, comprise submersible pump, top guide bearing, filter and filter layer are installed on the last blower inlet casing of pump shaft top of submersible pump, circulation water channel and weep hole are arranged at the pump shaft top that it is characterized in that submersible pump, circulation water channel one end pass-out pump shaft top, and the other end communicates with weep hole, and weep hole communicates with the pump shaft outside, with the corresponding pump shaft of the weep hole outside hydroecium is arranged.
2. Submerged Motor Pumps top guide bearing according to claim 1 is prevented the silt particle device, it is characterized in that being set with the oil sealing box on the pump shaft of weep hole or circulation water channel below, and the oil sealing box is fixedly mounted on the blower inlet casing, and outside framework oil seal is installed in the oil sealing box.
