Abstract
The utility model relates to an improved structure of a heat resisting, corrosion resisting and novel shaft sleeve seal, in particular to an improved structure for simplifying the installation of a chemical pump and reinforcing the sealing effect during high-temperature corrosion resistant medium transportation. The improved structure comprises a pump shaft, an impeller, and a shaft sleeve, and is characterized in that spigot surfaces that are matched mutually are arranged in the opposite position of the impeller and the shaft sleeve, and a sealing gasket is arranged between the spigot surfaces. The utility model has the advantages that the installation difficulty of the water pump is simplified, simultaneously, the area of the sealing gasket is relatively increased, the procedure during machining is reduced, the cost is saved, and the sealing performance is reinforced.
Description
Technical field
The utility model relates to a kind of high temperature resistant, and the improvement structure of corrosion resistant novel shaft sleeve sealing is particularly simplified the improvement that chemical pump is installed, and strengthens the effect that seals when carrying the high temperature corrosion medium.
Background technique
Impeller of chemical centrifugal pump and axle sleeve place need sealing gasket, and temperature is not high, when corrosivity is not strong, get final product with conventional O type circle; And carrying high temperature, during the strong medium of corrosivity, enclose and can't satisfy with conventional O; Therefore need be high temperature resistant, corrosion resistant sealing gasket, if sealing surface is little, seam is for a long time.At first, can bring a lot of inconvenience during installation, secondly, sealing effect is also bad.Former pump (Fig. 1) is gone up impeller 11 has two seams 13 with axle sleeve 12 installation sealing gasket places 14, and complex procedures and sealing surface are less like this, be difficult for compressing with sealing gasket in high temperature and Korrosionsmedium, and the sealing gasket area are too small, have increased the difficulty when installing like this.
Summary of the invention:
The purpose of this utility model is to solve that impeller of chemical centrifugal pump adopts the existing the problems referred to above of many seams face seal with the axle sleeve place in the prior art, provides a kind of high temperature resistant, the improvement structure that corrosion resistant novel shaft sleeve seals.The utility model designs a kind of high temperature resistant, and the improvement structure of corrosion resistant novel shaft sleeve sealing comprises pump shaft, impeller, axle sleeve, and it is characterized in that: impeller and axle sleeve opposite position respectively have a seam face that cooperatively interacts, and between two seam faces sealing gasket are arranged.The utility model has the advantages that and simplify the water pump installation difficulty that increased the area of sealing gasket simultaneously relatively, the operation when reducing machining is saved cost, strengthens sealability.
Description of drawings:
Fig. 1 is the prior art constructions schematic representation,
Fig. 2 is a structural representation of the present utility model,
Below in conjunction with accompanying drawing and example the utility model is made detailed operation instruction.
Embodiment:
Impeller has only a seam to cooperate with axle sleeve, has so just simplified the difficulty when assembling and has increased sealing area relatively.Operation when reducing machining is saved cost, strengthens sealability.
