This utility model solves the technical problem in the presence of prior art by following technical proposals:

A kind of pump with active clapboard, including a feed tube, a drain pipe, a pump housing and a drive shaft, described drives Moving axis is connected with the center rotating of the described pump housing, and the described pump with active clapboard also includes a driving dish and a sealing Chamber；Described annular seal space is connected with the described pump housing, and described feed tube and drain pipe are arranged in the both sides of joint；

The end of described drive shaft is provided with a disk, the axis of the drive shaft described in the deviation of the center of circle of described disk Arrange and be mutually connected vertically with described drive shaft；

Described driving dish be provided centrally with a circular hole, the edge of described driving dish is provided with a dividing plate；

Described disk is rotationally connected with described circular hole, and the end of described dividing plate is stretched in described annular seal space, institute The dividing plate stated forms, with the lower end of described annular seal space, the sliding connection structure sealed.

As this utility model preferred embodiment, the sliding connection structure of described sealing includes being arranged under annular seal space End is provided with two and is disposed with an arch sealing block in described circular groove to the circular groove arranged, described Arch sealing block includes that a circular arc sealing surface and a smooth seal face, described circular arc sealing surface slide with described circular groove Connecting, described smooth seal face is slidably connected with described dividing plate.

Advantage with the pump of active clapboard of the present utility model is: on-bladed designs, and structure is relatively simple, production cost Relatively low, the poor active clapboard of intensity is used only as seal applications, and reliability is higher.

Detailed description of the invention

Below preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature energy It is easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.

Advantage with the pump of active clapboard of the present utility model is: on-bladed designs, and structure is relatively simple, production cost Relatively low, the poor active clapboard of intensity is used only as seal applications, and reliability is higher.

As shown in Figure 1 and Figure 2, a kind of pump with active clapboard, including feed tube 1, drain pipe 2, pump housing 3 and One drive shaft 4, this drive shaft 4 is connected with the center rotating of this pump housing 3, should also include a driving dish 5 with the pump of active clapboard With an annular seal space 6；This annular seal space 6 is connected with this pump housing 3, and this feed tube 1 and drain pipe 2 are arranged in the both sides of joint；

As it is shown on figure 3, the end of this drive shaft 4 is provided with a disk 41, this drive shaft 4 is deviateed in the center of circle of this disk 41 Axis is arranged and is mutually connected vertically with this drive shaft 4；

As shown in Figure 4, this driving dish 5 be provided centrally with a circular hole 51, the edge of this driving dish 5 is provided with a dividing plate 52；

As it is shown in figure 1, this disk 41 is rotationally connected with this circular hole 51, the end of this dividing plate 52 is stretched in this annular seal space 6, should Dividing plate 52 forms, with the lower end of this annular seal space 6, the sliding connection structure sealed.

Under the driving of this drive shaft 4, this driving dish 5 can periodically in this pump housing 3 put, thus can periodically by Through the liquid that feed tube 1 enters, push drain pipe 2 side to, it is achieved the function of pump.Can be it is clear to see that this with activity The pump structure of dividing plate is relatively simple, and amount of parts is less, and the regular shape of parts, and processing cost is higher, and quality is Only it is used for separating feed tube 1 and drain pipe 2 for weak dividing plate 52, makes it to connect, be therefore easier to fully seal, reliably Property is higher.

As shown in Figure 1, Figure 2, Figure 5, the sliding connection structure of this sealing includes that being arranged on annular seal space 6 lower end is provided with two To the circular groove 61 arranged, being disposed with an arch sealing block 7 in this circular groove 61, this arch sealing block 7 includes One circular arc sealing surface 71 and a smooth seal face 72, this circular arc sealing surface 71 is slidably connected with this circular groove 61, this plain seal Face 72 is slidably connected with this dividing plate 52.

It is only more than the mentality of designing of some embodiments of the present utility model, in the case of system allows, this reality The most external more functional module can be expanded to novel, thus extend its function to greatest extent.

The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to In this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
