[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] In order to improve the running stability of the plunger pump when high-speed liquid is introduced, Figure 1-4 As shown, a plunger pump housing of the utility model comprises a base 1, a support column 3, a housing 4, a liquid outlet 6 and a liquid inlet 7. The top of the base 1 is provided with a housing 4 through the support column 3, and the two ends of the top of the housing 4 are respectively provided with a liquid outlet 6 and a liquid inlet 7;

[0024] Wing plates 10 are provided on the outside of the liquid outlet 6 and the liquid inlet 7. Both sides of the top of the wing plate 10 are connected to the horizontal plate 9 by the first screw 8. The top side of the horizontal plate 9 is connected to the vertical plate 12 by the second screw 11. Both sides of the top of the base 1 are installed with sleeve blocks 14 by the third screws 13. The sleeve block 14 is sleeved with a circular rubber block 15. The circular rubber block 15 is located on the outside of the bottom end of the vertical plate 12.

[0025] When in use, a group of extended structures are conveniently formed on the outside of the liquid outlet 6 and the liquid inlet 7 through the wing plate 10, the cross plate 9 and the vertical plate 12. When the external high-speed liquid flows through the liquid outlet 6 and the liquid inlet 7, the vibration is transmitted to the vertical plate 12. The circular rubber block 15 in the sleeve block 14 is convenient for absorbing the vibration of the vertical plate 12, so that the liquid outlet 6 and the liquid inlet 7 can be firmly connected with the external pipeline, which is beneficial to improving the stability of the plunger pump during operation.

[0026] For example, Figure 1 As shown, the utility model also includes that an active cavity 16 is opened near one end in the shell 4, a liquid-passing cavity 19 is arranged at one end in the shell 4 away from the active cavity 16, a plunger mounting groove 17 is opened near one end in the shell 4 near the active cavity 16, a blocking cavity 18 connected with the liquid-passing cavity 19 is opened through one end of the plunger mounting groove 17, the liquid inlet 7 is connected with the active cavity 16, and the liquid outlet 6 is connected with the liquid-passing cavity 19.

[0027] When in use, the movable chamber 16 is used to facilitate the installation of structures such as the cylinder body and the inclined plate. The plunger is conveniently installed at one end of the inner wall of the plunger installation groove 17. The plunger is connected to the inclined plate through a universal ball seat. A stop valve structure is also installed on the inner wall of the liquid chamber 19 near the blocking chamber 18 for opening and closing the blocking chamber 18.

[0028] To install the input shaft, for example, Figure 1 and Figure 2 As shown, an input shaft reserved groove 5 which is communicated with the active cavity 16 is provided near the center of one end of the housing 4 .

[0029] When in use, the input shaft is conveniently limited and fixed by the input shaft reserved groove 5 , and the output end of the input shaft is connected to the swash plate located in the active cavity 16 .

[0030] In order to facilitate the connection of the liquid outlet 6 and the liquid inlet 7 with the external pipeline to improve the anti-slip effect of the pipeline, for example, Figure 1 and Figure 2 As shown, the utility model also includes that the outer peripheries of the top ends of the liquid outlet 6 and the liquid inlet 7 are both provided with annular protrusions.

[0031] When in use, the external hose is sleeved on the outside of the annular protrusions on the periphery of the top of the liquid outlet 6 and the liquid inlet 7, and then the position of the hose near the lower end of the annular protrusion is locked with a clamp, thereby improving the anti-slip effect when connecting the external hose to the top of the liquid outlet 6 and the liquid inlet 7.

[0032] For example, Figure 1 As shown, the utility model also includes that the bottom of the base 1 is penetrated by a mounting hole 2 near the corner.

[0033] When in use, external bolts are passed through the mounting holes 2 to facilitate stable mounting of the housing.

[0034] When the utility model is in use, the external bolts are passed through the mounting holes 2 to facilitate the stable mounting of the housing, the external hose is sleeved on the outer side of the annular protrusions at the top periphery of the liquid outlet 6 and the liquid inlet 7, and the position of the hose near the lower end of the annular protrusion is locked by a clamp, so as to improve the anti-slip effect when the external hose is connected to the liquid outlet 6 and the liquid inlet 7.

[0035] Through the wing plate 10, the horizontal plate 9 and the vertical plate 12, a group of extended structures are conveniently formed on the outside of the liquid outlet 6 and the liquid inlet 7. When the external high-speed liquid flows through the liquid outlet 6 and the liquid inlet 7, the vibration is transmitted to the vertical plate 12. The circular rubber block 15 in the sleeve block 14 is convenient for absorbing the vibration of the vertical plate 12, so that the liquid outlet 6 and the liquid inlet 7 can be firmly connected with the external pipeline, which is beneficial to improving the stability of the plunger pump during operation.
