Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The first embodiment is as follows:

as shown in figure 1, the utility model relates to a canned type high viscosity pneumatic pump, including support 2, pneumatic motor 3 is installed to support 2 upper ends, and plunger pump 1 is installed to the mid position. As shown in fig. 2, the plunger pump 1 includes a pump body 11, a piston rod 12 driven by a penetrating pneumatic motor 3 is arranged in the pump body 11, a first guide sleeve 13 and a second guide sleeve 14 are further sequentially arranged, the piston rod 12 is sleeved with the first guide sleeve 13, a first seal ring 15 is clamped at the lower end of the first guide sleeve 13, and a guide plate 16 is further clamped at the upper end of the pump body 11. The first guide sleeve 13 is sealed with the pump body 11 by an O-ring, and the guide plate 16 is sealed with the first guide sleeve 13 by an O-ring.

The lower end of the guide plate 16 is provided with a first boss 163 for clamping the inner hole of the pump body 11. The upper end of the guide plate 16 is also provided with a pressure plate 19, and the pressure plate 19 is connected with the pump body 11 under the action of bolts to realize the fixation of the guide plate 16.

The guide plate 16 is provided with a guide channel 17 connecting the inner and outer walls.

The arrangement of the flow guide channel 17 ensures that the leaked medium flows out along the flow guide channel 17 to realize collection or flow back to the raw material barrel again; so set up, neither can cause the raw materials extravagant, still can not influence pneumatic pump normal operating.

Example two:

compared with the first embodiment, the differences are as follows: the guide passage 17 includes a lower concave stage 161 disposed on the first boss 163, and further includes a guide hole 162 located in the radial direction of the second seal ring 18, and the guide hole 162 is communicated with the lower concave stage 161. The conventional flow guide channel 17 is a through hole communicated with the inner wall and the outer wall, so that the medium cannot be discharged in time, and the technical problem is solved by the arrangement.

Example three:

compared with the two examples, the difference is that: as shown in fig. 3, the upper end of the deflector 16 is further provided with an upper concave platform 164, and the second sealing ring 18 is clamped in the upper concave platform 164. The second sealing ring 18 can prevent part of the medium from overflowing from the upper end of the guide plate 16. The provision of the upper recessed land 164 also facilitates the installation of the second seal ring 18.

Example four:

compared with the three phases of the embodiment, the differences are as follows: as shown in FIG. 3, the lower end of the pressing plate 19 is provided with a second boss 191, and the second boss 191 is clamped with the upper concave platform 164. The second boss 191 is used for not only mounting and positioning the pressure plate 19, but also compressing the second seal ring 18, so that the second seal ring 18 is mounted more firmly.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention.
