The plunger pump is an important device of a hydraulic system, has the advantages of high rated pressure, compact structure, high efficiency, convenient flow regulation and the like, and is widely applied to occasions with high pressure, large flow and flow needing to be regulated. The existing plunger pump adopts an integrally formed pump core, and once the pump core is damaged, the whole pump core needs to be replaced, so that the cost is high.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides a pump core device for a plunger pump.
The technical problem of the invention is mainly solved by the following technical scheme:
the utility model provides a pump core device for plunger pump, a serial communication port, a pump core device for plunger pump contain casing and one and go up the casing, last casing and be equipped with a detachable pump dish down between the casing, the pump dish contain a discoid disk body, the center of disk body be equipped with a dish hole, the lateral wall of disk body on be equipped with a pump board notch array of constituteing by the pump board notch, one side of pump board notch be equipped with a pair of fixed round hole respectively, the pump board notch in be equipped with a separable pump board respectively, a pair of locking pin runs through respectively fixed round hole and support the pump board.
As a preferred embodiment of the invention, the arrangement direction of the notches of the pump plate and the fixed round hole are mutually 30 degrees.
As a preferred embodiment of the invention, the pump plate is made of nylon.
The pump core device for the plunger pump has the following advantages: during the use, after the pump board takes place wearing and tearing, the user directly unscrews the locking pin, takes out the intraoral pump board in pump board slot to change new pump board, screw again the locking pin can, simple and convenient, it is convenient to change, maintenance low cost. In addition, because the setting direction of the notch of the pump plate and the fixed round hole mutually form 30 degrees, when the pump disc rotates, the sealing performance of the pump plate and the pump shell can be effectively kept, and the effect is obvious. The pump core device for the plunger pump is simple in structure, obvious in effect, low in cost and high in practicability.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.
As shown in fig. 1 to 5, the pump core device 1 for a plunger pump includes a lower casing 2 and an upper casing 3, a detachable pump plate 4 is disposed between the upper casing 3 and the lower casing 2, the pump plate 4 includes a disc-shaped plate 40, a plate hole 41 is disposed at the center of the plate 40, a pump plate notch array composed of pump plate notches 42 is disposed on a side wall of the plate 40, a pair of fixing circular holes 43 is disposed at one side of the pump plate notches 42, a separable pump plate 5 is disposed in the pump plate notches 42, and a pair of locking pins 6 respectively penetrate through the fixing circular holes 43 and abut against the pump plate 5.
The pump plate notches 42 are arranged at 30 deg. to each other with respect to the fixing circular hole 43.
The pump plate 5 is made of nylon.
During the use, as shown in fig. 1 and 2, after pump plate 5 takes place wearing and tearing, the user directly unscrews locking pin 6, takes out pump plate 5 in the pump plate notch 42 to more renew pump plate 5, the locking pin 6 of screwing again can, simple and convenient, it is convenient to change, and maintenance cost is cheap.
In addition, because the arrangement direction of the pump plate notch 42 and the fixed round hole 43 form 30 degrees with each other, when the pump disc 4 rotates, the sealing performance of the pump plate 5 and the pump shell can be effectively kept, and the effect is obvious.
The pump core device for the plunger pump is simple in structure, obvious in effect, low in cost and high in practicability.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
