Abstract
The utility model relates to a pump shaft for water pumps, which belongs to the water pump parts. The pump shaft for water pumps mainly comprises a pump shaft body, and is characterized in that a chromium ion layer is covered on the outer surface of a sealing section of the pump shaft body. The chromium ion layer has relatively high wear-resistant property, thereby achieving wear-resistance, anti-attrition and mating properties. The utility model has the advantages of simple and practical structure, convenient processing and manufacturing and high practicability, can effectively prolong the service life of the pump shaft without rusting, is high in smooth finish and low in friction coefficient, and can effectively reduce energy consumption when in use.
Description
Technical field
The utility model belongs to the water pump appliance, is specifically related to the transmission pump shaft of water pump.
Background technique
The application area of water pump is very wide, and present water pump generally is made up of the pump housing and impeller, and impeller is driven by pump shaft and rotates, and finishes the water delivery operation.Pump shaft stretches in the pump housing by the gland on the pump housing, adds formation such as filler, machinery envelope between pump shaft and the gland and compresses sealing, guarantees the relative negative pressure in the pump housing.Because the pump shaft rotational speed is higher, and frictional force is bigger between the filler, after long-time the use, this section pump shaft can form certain wearing and tearing, influences sealability, has to scrap processing when serious, and working life is short.
Summary of the invention
The water pump pump shaft that provides a kind of shoe to be provided with the chromium ion layer is provided the purpose of this utility model.
Of the present utility model being achieved in that
The water pump pump shaft mainly is made up of the pump shaft body, and the pump shaft body comprises impeller position, seal section position, bearing gland position, belt pulley position, it is characterized in that: the outer surface at pump shaft body seal section position has also been carried out one deck chromium ion layer.
After the utility model adopts said structure, owing to handle shoe by chromium plating one deck chromium ion layer is arranged at the outer surface at pump shaft position easy to wear, the chromium ion layer has stronger wear-resisting property, thereby reach wear-resisting, anti-attrition and matching property energy, have convenient, the practical effect of simple and practical, processing and fabricating, can effectively increase the working life of pump shaft, and non-corrosive, highly polished, friction factor is low, can effectively reduce energy consumption during use.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that pump shaft body, 2 is the chromium ion layer.
As shown in Figure 1, the utility model is a kind of water pump transmission pump shaft, mainly is made up of pump shaft body 1, and pump shaft body 1 mainly comprises impeller position, seal section position, bearing gland position, belt pulley position, the seal section position is mainly used in the sealing that compresses with filler, and wear resistance is had relatively high expectations.As shown in Figure 1, 2, establish one deck chromium ion layer 2 at the outer surface shoe at seal section position, thickness is between 0.02-0.04mm, to satisfy wear resistance and smoothness requirement.During making, the seal section position is placed on contains in the chromium soup,, make the outer surface of chromium ion attached to the seal section position by plating mode; Carry out chromising then and handle, make the outer surface micropore at seal section position infiltrate chromium ion, form chromium ion layer 2, other position maintains the original state.Can realize scrapping on an equal basis of pump shaft body 1.
Because chromium ion layer 2, intensity height, smoothness are good, can effectively increase the wear-resisting property of this section pump shaft, and effectively reduce friction factor, thereby effectively increase the working life of whole pump shaft.Above-mentioned chromium ion layer 2 also can be replaced by the strong sheath of other wear resistance.
Claims (2)
1, water pump pump shaft, mainly form by pump shaft body (1), pump shaft body (1) comprises impeller position, seal section position, bearing gland position, belt pulley position, it is characterized in that: the outer surface at pump shaft body (1) seal section position has also been carried out one deck chromium ion layer (2).
2, water pump pump shaft according to claim 1 is characterized in that: the thickness of described chromium ion layer (2) is 0.02-0.04mm.
