Abstract
The utility model discloses a centrifugal water pump gas-leakage-proof shaft sleeve, which comprise a centrifugal shaft, a filler culvert which is arranged on the centrifugal shaft, a cover of the filler culvert and an impeller which is arranged on one side of the filler culvert. The utility model is characterized in that a gas-leakage-proof shaft sleeve is arranged on a centrifugal shaft on the other side of the filler culvert, and one end cover of the gas-leakage-proof shaft sleeve is fixedly connected on the filler culvert. The gas-leakage-proof shaft sleeve is formed by a cannula whose one end is provided with an oil seal seat and the other end is connected with a flange plate, and a filler pipe is arranged on the cannula, lubricating oil is filled in the gap between the shaft sleeve and a shaft of the utility model, and dense lubricating oil is not only used to lubricate filler culvert, and meanwhile, seals the gap between the filling culvert and the shaft, the dense lubricating oil not only guarantees lubrication and prolongs the service span of the shaft and the filler culvert, but also avoids air leakage, improves working efficiency of the pump, and lowers the production cost.
Description
Technical field:
The utility model relates to mechanical field, is specifically related to the Centrifugal water pump in the mechanical field.
Background technique:
Centrifugal water pump is widely used in the agricultural production, but present Centrifugal water pump, in use exist following open defect: owing to be used to prevent that the filler that leaks gas from containing and centrifugal shaft is the soft or hard Spielpassung, work friction for a long time reduces between centers lubricant oil gradually, so that dry, causing filler to be contained with the axle wearing and tearing accelerates, not only cause gas leakage, the working efficiency of pump is reduced, and had a strong impact on the working life of axle and filler culvert.As be used for the sand suction machine that sand is adopted in the korneforos, and for above-mentioned reasons, make and inhale the sand amount and inhale the sand lift all very low, when inhaling the higher sand of concentration, tend to sand suction machine to be worked because of the faint gas leakage of between centers.Therefore, this Centrifugal water pump, generally can only work 10 to 15 days must shutdown maintenance, increased cost of production greatly.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of Centrifugal water pump anti-gas-leak axle sleeve, improves the working efficiency of pump, and the working life of axle and filler culvert.
The utility model is achieved through the following technical solutions:
Centrifugal water pump anti-gas-leak axle sleeve, the filler that comprises centrifugal shaft, is arranged on the centrifugal shaft is contained and lid, and be positioned at the impeller that filler is contained a side, and characteristics are that the anti-gas-leak axle sleeve is arranged at filler and contains on the centrifugal shaft of opposite side, an end of anti-gas-leak axle sleeve is fixed on the filler that filler contains and contains.
Described anti-gas-leak axle sleeve is contained by filler and an end is provided with the sleeve pipe that oil sealing base, the other end be provided with mounting flange and constitutes; Also be provided with oil filling pipe on the sleeve pipe.The internal diameter of anti-gas-leak axle sleeve is slightly larger than the external diameter of centrifugal shaft.
The utility model compared with prior art has following obvious advantage:
The centrifugal shaft that the utility model filler is contained a side is provided with the anti-gas-leak axle sleeve, axle sleeve one end is contained with filler and is fixedlyed connected, axle sleeve is provided with the oil filling pipe of lubricant oil, the gap of axle sleeve and axle is lubricant oil abrim, dense thick lubricant oil is not only contained lubricated for filler, simultaneously filler is contained with the gap of axle and shut, both guaranteed lubricated, the wearing and tearing of filler culvert have been avoided with axle, prolong the working life that axle and filler are contained, stopped gas leakage simultaneously, improved the working efficiency of Centrifugal water pump, satisfy the production demand, reduced cost of production.
Description of drawings:
Fig. 1 takes dress attitude schematic representation apart for the utility model.
