Abstract
The utility model discloses a water pump shaft sleeve seal structure, including interior axle sleeve, the top of interior axle sleeve impeller wheel hub contact surface is provided with the ring channel, be provided with corrosion resistance's O type rubber ring in the ring channel, just the degree of depth of ring channel is not less than half of O type rubber ring diameter. The utility model aims at providing a water pump shaft sleeve seal structure to the sealed problem of axle sleeve and impeller wheel hub contact surface in changing.
Description
Technical Field
The utility model relates to a water pump shaft sleeve seal structure.
Background
The main equipment is water pumps, and these water pumps are single-stage double-suction centrifugal water pumps, in the process of mounting the shaft sleeve and impeller of the water pump, the contact surface between the inner shaft sleeve and the impeller hub is locked by the shaft sleeve back cap to achieve the sealing effect, because of the rough machining precision, a gap is generated between the shaft sleeve and the hub, the back cap is locked but cannot achieve the sealing effect in the mounting process, when the equipment is operated, the liquid enters the gap between the shaft sleeve and the shaft through the gap of the contact surface and flows out through the gap of the back cap, so that the water pump cannot achieve the operation efficiency, meanwhile, the liquid with pressure rushes into the bearing body to deteriorate the lubricating oil, the bearing is damaged, the bearing needs to be overhauled and replaced when the operation period is not reached, the shaft sleeve is also sealed by the hemp cushion, but is easy to wear after the operation time is long due to corrosion and the hemp cushion of centrifugal force, the shaft sleeve is caused to loose liquid to leak out of the shaft from a gap between the shaft sleeve and the shaft, and meanwhile, the effective lift of the water pump is reduced due to the loose water leakage of the shaft sleeve, so that the requirement of blast furnace water utilization is not met, and the production is influenced. Therefore, a maintainer needs to open the pump cover, disassemble the rotor, unscrew the shaft sleeve back cap and add hemp again, and if the contact surface of the impeller hub and the shaft sleeve is abraded, the impeller and the shaft sleeve also need to be replaced, so that the overhauling frequency is increased, the spare part cost of equipment is increased, and the labor intensity of post personnel is also increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a water pump shaft sleeve seal structure to the sealed problem of axle sleeve and impeller wheel hub contact surface in changing.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model relates to a water pump shaft sleeve seal structure, including interior axle sleeve, the top of interior axle sleeve impeller wheel hub contact surface is provided with the ring channel, be provided with corrosion resistance's O type rubber ring in the ring channel, just the degree of depth of ring channel is not less than half of O type rubber ring diameter.
Further, the diameter of the annular groove is 5mm, and the depth of the annular groove is 3 mm.
Compared with the prior art, the utility model discloses a beneficial technological effect:
the utility model discloses a seal structure processing is convenient, swift, with low costs, and simple to operate can make the operating power that equipment reached, can improve equipment's operating cycle again, has reduced maintenance rate and spare parts cost and has also reduced post staff's intensity of labour simultaneously.
Drawings
The present invention will be further explained with reference to the following description of the drawings.
Fig. 1 is a front view of the water pump shaft sleeve sealing structure of the present invention;
fig. 2 is a left side view of the water pump shaft sleeve sealing structure of the present invention;
description of reference numerals: 1. an inner sleeve; 2. an annular groove; 3. and an O-shaped rubber ring.
Detailed Description
As shown in figures 1 and 2, the water pump shaft sleeve sealing structure utilizes an original inner shaft sleeve, the top center part of the contact surface of the inner shaft sleeve 1 and an impeller hub is circled, an annular groove 2 with the diameter of 5mm and the depth of 3mm is processed, a corresponding corrosion-resistant O-shaped rubber ring 3 is installed in a matched mode, and the protruding rubber ring is locked through a shaft sleeve back cap during installation to play a role in sealing the impeller hub and the top end of the shaft sleeve.
The utility model discloses an interior axle sleeve seal structure is through the convex 1\2 rubber circle of processing installation and impeller wheel hub contact surface through axle sleeve back of the body cap lock dead sealedly, can effectively stop the emergence of leaking, effectual reduction maintenance frequency with reduced spare parts expense, the life who improves the bearing simultaneously also has reduced post personnel' S intensity of labour simultaneously, makes the scene reach the 5S standard.
The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
