Abstract
The utility model discloses an anti-corrosion shaft seal end cap device. The anti-corrosion shaft seal end cap device is in an arc shape, clamping corners are evenly distributed on the edge of the arc-shaped end cap device, the clamping corners are fixedly connected with an impeller, and a round part in the middle of the arc-shaped end cap device is inserted into an inner hole of the impeller to be connected in a sealed mode. The anti-corrosion shaft seal end cap device overcomes the defects that an end cap shaft seal falls back, loosens, and is not smooth in airflow and poor in anti-corrosion effect and the like, and enables a draught fan in highly corrosive environment to be good in sealing effect and stable in running.
Description
Technical field
The utility model relates to a kind of end cover, relates in particular to a kind of anti-corrosion shaft end cover device.
Background technique
Be used at present the blower fan of high corrosive environment, axle head has two kinds of sealing means, and the first (axle dynamic formula or belt type) all adopts lock washer and round nut to lock to seal, and does not have the shaft end seal effect under high corrosive environment.Bring in sealing before the second (direct-type) all adopts a block plate and anti-corrosion material to press to be locked into motor shaft, this axle front end can play seal action, but blower fan starts when frequent, the sealing of motor shaft front end can be become flexible, and the axle front end is steel plate, and intake resistance is large, and air-flow is smooth and easy not.
The model utility content
The utility model purpose is to provide a kind of anti-corrosion shaft end cover device for the defective that prior art exists.
The utility model adopts following technological scheme for achieving the above object:
The utility model anti-corrosion shaft end cover device, described end cap device camber, and at the uniform Ka Jiao in arc tips lid arrangement edge, described Ka Jiao is fixedly connected with impeller, the circular impeller endoporus that inserts in described arc tips lid arrangement middle part is tightly connected.
Preferably, between described arc tips lid arrangement middle part circular front end and the impeller endoporus seal ring is set also.
The utility model overcome end-cover axle be honored as a queen move back, become flexible, the shortcomings such as air-flow has some setbacks, preserving and sealing weak effect, make the blower fan preserving and sealing of high corrosive environment effective, smooth running.
Description of drawings
Fig. 1: the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model anti-corrosion shaft end cover device, described end cap device 1 camber, and at the uniform Ka Jiao in arc tips lid arrangement edge, described Ka Jiao is fixedly connected with impeller 3.
Preferably, the circular 4 insertion impeller endoporus in described arc tips lid arrangement middle part are tightly connected.
Preferably, between described arc tips lid arrangement middle part circular front end and the impeller endoporus seal ring 2 is set also.
The utility model anti-corrosion shaft end cover device adopts plastic materials, and integrated through injection molding is shaped, and overall structure is tight.Shaft sealing end cap configuration design camber at uniform several Ka Jiao of arcuate perimeter, increases reinforcing steel at arc bosom position, increases O V-shaped ring (seeing Fig. 1 for details) at the reinforcing steel front end.When end cap Ka Jiao snaps in impeller, the O V-shaped ring of reinforcing steel front end also with impeller endoporus tight seal, end cap, impeller, motor shaft are tightly connected, the front cover shaft seal can not retreated, can not become flexible, airflow smooth, preserving and sealing is effective.
The above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. anti-corrosion shaft end cover device, described end cap device camber, and at the uniform Ka Jiao in arc tips lid arrangement edge, described Ka Jiao is fixedly connected with impeller, it is characterized in that the circular impeller endoporus that inserts in described arc tips lid arrangement middle part is tightly connected.
2. anti-corrosion shaft end cover device according to claim 1 is characterized in that between described arc tips lid arrangement middle part circular front end and the impeller endoporus seal ring being set also.
