Abstract

The invention discloses a pump core device for a plunger pump. The pump core device comprises a lower shell and an upper shell. A detachable pump disk is arranged between the upper shell and the lower shell. The pump disk contains a disciform disk body, the center of which is provided with a disk hole. The sidewall of the disk is provided with a pump plate notch array composed of pump plate notches. A pair of fixed circular holes is respectively arranged at one side of each pump plate notch. A detachable pump plate is respectively arranged inside each pump plate notch. A pair of locking pins respectively penetrates the corresponding fixed circular holes to be abutted against the corresponding pump plate. When the pump core device is in use and after a pump plate is worn, a user directly unscrews the locking pins to take the pump plate out of the pump plate notch and replaces a new pump plate and finally screws the locking pins. The device is simple and convenient, is convenient to replace pump plates and has low cost of maintenance. The pump core device for a plunger pump has a simple structure, has obvious effects, is low-cost, and has strong practicality.

Description

technical field [0001] The present invention relates to a plunger pump, more precisely, to a pump core device for the plunger pump. Background technique [0002] The plunger pump is an important device in the hydraulic system. It has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. It is widely used in high pressure, large flow and flow adjustment occasions. Existing plunger pumps use an integrally formed pump core, and once damaged, the entire pump core must be replaced, resulting in relatively high costs. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a pump core device for a plunger pump. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A pump core device for a plunger pump, characterized in that, the pump core device for a plunger pump comprises a lower ...
