Description
Technical Field
The utility model relates to a plunger pump.
Background
The plunger pump adopts plane flow distribution at the earliest, and along with the improvement of the pressure of the plunger pump, the plane flow distribution generates deflection due to the high pressure of the cylinder body, so that the abrasion of the cylinder body is increased, the service life is short, the maintenance is frequently needed, and the use effect is poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects in the prior product and providing a plunger pump.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the plunger pump comprises a cylinder body, a conical surface valve plate, an end cover, a first bearing, a main shaft, a second bearing and a shell, wherein the shell is connected with the end cover through a bolt, the conical surface valve plate is installed on the end cover, the conical surface valve plate is sleeved on the main shaft, the first bearing is installed on the shell, the second bearing is installed on the end cover, one end of the main shaft is in interference fit with the first bearing, the other end of the main shaft is in interference fit with the second bearing, and the cylinder body is connected with the main shaft in a spline mode.
Preferably, the conical surface valve plate further comprises a positioning pin, and the conical surface valve plate is installed on the end cover through the positioning pin.
Preferably, the side surface of the conical port plate is a conical surface.
Preferably, the cylinder is located within the housing.
Preferably, the conical port plate is located between the cylinder body and the end cover.
The utility model has the advantages as follows: the utility model discloses a conical surface valve plate can axial and radial centering, and rotating part can have small amplitude relative oscillation, and is high pressure resistant, effectively reduces cylinder body terminal surface degree of wear, the utility model discloses the structure size is little, and the processing equipment drops into fewly, can realize online measurement, and the part is with low costs.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic top view of a conical port plate;
FIG. 3 is a side view of a conical port plate.
Detailed Description
The technical scheme of the utility model is further explained by combining the attached drawings of the specification:
as shown in fig. 1 to 3, the plunger pump includes a cylinder body 1, a conical surface port plate 2, an end cover 3, a first bearing 7, a main shaft 6, a second bearing 4, and a housing 8, the housing 8 is connected with the end cover 3 through a bolt, the conical surface port plate 2 is installed on the end cover 3, the conical surface port plate 2 is sleeved on the main shaft 6, the first bearing 7 is installed on the housing 8, the second bearing 4 is installed on the end cover 3, one end of the main shaft 6 is in interference fit with the first bearing 7, the other end of the main shaft 6 is in interference fit with the second bearing 4, and the cylinder body 1 is connected with the main shaft 6 through a spline.
As shown in fig. 1 to fig. 3, the cylinder further includes a positioning pin 5, the conical surface port plate 2 is mounted on the end cover 3 through the positioning pin 5, the side surface of the conical surface port plate 2 is a conical surface, the cylinder body 1 is located in the housing 8, and the conical surface port plate 2 is located between the cylinder body 1 and the end cover 3.
The cylinder body 1 is connected with the main shaft 6 through a spline mode, so that when the main shaft 6 rotates, the main shaft 6 drives the cylinder body 1 to rotate.
The utility model discloses a conical surface valve plate can axial and radial centering, and rotating part can have small amplitude relative oscillation, and is high pressure resistant, effectively reduces cylinder body terminal surface degree of wear, the utility model discloses the structure size is little, and the processing equipment drops into fewly, can realize online measurement, and the part is with low costs.
It should be noted that the above list is only one specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications can be made, and in short, all modifications that can be directly derived or suggested by the person skilled in the art from the disclosure of the present invention should be considered as the protection scope of the present invention.
