Abstract

The utility model relates to a sealing improvement between a double-suction pump shaft and a filling shaft sleeve, comprising a shaft, a filing shaft sleeve and an O-shaped sealing ring, wherein an O-shaped sealing groove is arranged in the inner hole of the end of the filling shaft sleeve, a bevel angle at the shaft shoulder of the shaft matched with the filling shaft sleeve is 5*15 degrees, an O-shaped sealing ring is arranged in the groove of the filling shaft sleeve. The sealing improvement of the utility model has advantage as follows: when mounting, the frication distance of the O-shaped sealing ring and the shaft is short without damaging the O-shaped sealing ring, due to the bevel angle with 5*15 degrees at the shaft shoulder, the O-shaped sealing ring exceeds the shaft shoulder easily, so that the O-shaped sealing ring is almost barely damaged, and the part of the O-shaped sealing ring is cut, so the mounting is easier and the tightness is better.

Description

The improvement that seals between double suction pump shaft and packing sleeve
Technical field
The utility model relates to the improvement that seals between a kind of large-scale double suction pump shaft and packing sleeve.
Background technique
The seal form of double suction pump has two kinds of mechanical seal and packing seals.When sealing configuration adopted packing seal, the sealing between packing sleeve and the axle was most important, and use O RunddichtringO can be realized the sealing between the two.Be processed with O RunddichtringO groove on the axle, the O RunddichtringO is put into groove, in the process that packing sleeve is installed, almost 90% of the packing sleeve length overall all will be unfavorable for assembling with the friction of O RunddichtringO; Because the gap between packing sleeve and the axle is very little, in installation process, the O RunddichtringO is difficult for by the shaft shoulder simultaneously, and it is very serious to wear and tear, and can the part of O RunddichtringO be cut off along the fitting surface of packing sleeve with axle when serious, and sealing effect is bad.
Summary of the invention
The purpose of this utility model is to solve in the prior art for the existing the problems referred to above of packing seal structure double suction pump, provide a kind of easy to process, be convenient to assemble and the new structure of good sealing effect.The improvement that seals between the utility model design double suction pump shaft and packing sleeve, comprise axle, packing sleeve, O RunddichtringO, pump case, Gland, packing ring, it is characterized in that: be processed with O RunddichtringO groove at the terminal endoporus of packing sleeve, the shaft shoulder place that cooperates with packing sleeve on axle is processed with one 5 * 15 ° oblique angle, and the O RunddichtringO is placed in the groove of packing sleeve.The O RunddichtringO is very short with the frictional distance of axle when the utility model has the advantages that assembling, the O RunddichtringO can not wear and tear, again because shaft shoulder place has processed 5 * 15 ° oblique angle, the easier shaft shoulder of crossing of O RunddichtringO, to the almost not wearing and tearing of O RunddichtringO, more the part of O RunddichtringO can not cut off, make that assembling is easier and sealability is better.
Description of drawings
Fig. 1 is a double suction pump packing seal place sectional drawing of the present utility model.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment
Comprise axle 1, packing sleeve 2, O RunddichtringO 3 among the figure, pump case 4, Gland 7, packing ring 8, it is characterized in that: be processed with O RunddichtringO groove 5 at the terminal endoporus of packing sleeve, the shaft shoulder place that cooperates with packing sleeve on axle is processed with one 5 * 15 ° oblique angle 6, and the O RunddichtringO is placed in the groove of packing sleeve.
The O RunddichtringO is very short with the frictional distance of axle during assembling, the O RunddichtringO that can not wear and tear, and shaft shoulder place has processed 5 * 15 ° oblique angle, the easier shaft shoulder of crossing of O RunddichtringO, to the almost not wearing and tearing of O RunddichtringO, more the part of O RunddichtringO can not cut off, make sealability better.
