Abstract
Provided is a centrifugal sand pump shaft including a pump shaft, a shaft sleeve, and a plurality of flat keys. The tail end of the pump shaft is movably connected with the shaft sleeve, a plurality of opposite-opening keyways are arranged in the shaft sleeve, flat keyways cooperatively used with the opposite-opening keyways are arranged in the pump shaft, and any one of the opposite-opening keyways is fixed to the corresponding flat keyway via one of the flat keys. The shaft sleeve is threadedly connected with the pump shaft. The centrifugal sand pump shaft is advantageous in being simple in structure and convenient to use, being capable of achieving the aims of enhancing the hardness without the need for chrome-plating a shaft member, preventing the environment from being polluted by the chrome plating technology, being convenient for maintenance and reducing the production cost.
Description
(1) technical field
The utility model relates to a kind of Centrifugal Sand Pumps accessory, particularly relates to a kind of Centrifugal Sand Pumps pump shaft.
(2) background technique
At present, Centrifugal Sand Pumps working condition requires its sand pump axle wear-resisting property must be high, and therefore usual technological means is that the shaft part that mechanical seal is housed at sand pump axle carries out chromium plating and grinding, to improve hardness and precision herein.But because pump shaft working environment is extremely severe, in the drilling fluid that sand pump is carried, contain a large amount of silt and there is corrosive liquid, pump shaft carries out after chromium plating processing, improved hardness, but work long-time after, chromium coating still there will be groove, chromium coating is because hardness is high, general machining can not be repaired, and can only all scrap by whole pump shaft, extremely wastes the resources of production.Chrome-plated process is also more serious to the pollution of environment simultaneously.Just can reach the object that strengthens hardness and avoid the pump shaft of to environment, being simultaneously convenient to keep in repair, reduce production costs not also to be found thereby can not need on the market now that axle part is carried out to chromium plating, have to be developed.
(3) model utility content
In order to overcome the deficiency of existing Centrifugal Sand Pumps accessory, the utility model provides a kind of Centrifugal Sand Pumps pump shaft.
The technical solution of the utility model is to realize like this.
A kind of Centrifugal Sand Pumps pump shaft of this programme, comprises pump shaft, axle sleeve and some flat keys, and described pump shaft end is flexibly connected with axle sleeve; On described axle sleeve, be provided with some to splining; On described pump shaft, be provided with and the flat key groove being used in conjunction with splining; Arbitrarily described the flat key groove that splines corresponding with it is fixed by flat key.
Described axle sleeve is threaded with pump shaft.
Usefulness of the present utility model is: this device structure is simple, easy to use, can reach does not need that axle part is carried out to chromium plating and just can strengthen the object of hardness, thereby avoids owing to using chromium plating technology to environment, be convenient to maintenance simultaneously, reduce production costs.
(4) accompanying drawing explanation
Fig. 1 is Organizational Structure schematic diagram of the present utility model.
(5) embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made to brief description.
A Centrifugal Sand Pumps pump shaft as shown in drawings, comprises pump shaft 1, axle sleeve 2 and some flat keys 5, and described pump shaft 1 end is flexibly connected with axle sleeve 2; On described axle sleeve 2, be provided with some to splining 4; On described pump shaft 1, be provided with to the 4 flat key grooves 3 that are used in conjunction with that spline; Arbitrarily described the 4 flat key grooves 3 corresponding with it that spline are fixed by flat key 5.
Described axle sleeve 2 is threaded with pump shaft 1.
The working procedure of this example: while using this device, first axle sleeve 2 is enclosed within on pump shaft 1 and by spiral and is connected and fixed, then by 4 axle sleeve 2 is connected and is fixed with pump shaft 1 with the flat key groove 3 use flat keys 5 on pump shaft splining on axle sleeve 2, thereby avoid being subjected to displacement between axle sleeve 2 and pump shaft 1, do not need pump shaft 1 to carry out chrome-plated process, avoid environment, in the time there are wearing and tearing in pump shaft 1, can repair by axle sleeve 2, pump shaft 1 can normally be worked for a long time, easy to maintenance, reduce cost.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
Claims (2)
1. a Centrifugal Sand Pumps pump shaft, comprises pump shaft (1), axle sleeve (2) and some flat keys (5), it is characterized in that: described pump shaft (1) end is flexibly connected with axle sleeve (2); On described axle sleeve (2), be provided with some to spline (4); On described pump shaft (1), be provided with and the flat key groove (3) that spline (4) are used in conjunction with; Described fixing by flat key (5) to spline (4) flat key groove (3) corresponding with it arbitrarily.
2. a kind of Centrifugal Sand Pumps pump shaft according to claim 1, is characterized in that: described axle sleeve (2) is threaded with pump shaft (1).
