Abstract
The utility model relates to a chromium-plating plunger used for diesel fuel automobile injection pump, belonging to the field of mechanical parts, comprising a plunger sleeve and a plunger core; wherein, a layer of chromium is added on the working surface of the plunger core. Compared with the prior art, the utility model has the advantages of high hardness, good anti-friction property and long service life.
Description
Technical field:
The utility model belongs to the component of machine technical field, especially for the Injection Pump chromium plating plunger of diesel-oil vehicle.
Background technique:
In technique known, the injection pump plunger that uses on the diesel-oil vehicle, directly adopt Bearing Steel to make, because the working surface hardness of plug core can only be decided because of the hardness of its material itself, thereby can not reach desirable hardness requirement, and when plunger is worked in addition, the to-and-fro motion when long, make that plug core is low because of hardness, the wear resistance difference easily is worn, thereby reduce the working life of plunger.In addition, the plug core that is worn needs the continuous plunger that more renews owing to not using, and causes the user cost height of plunger.
Summary of the invention:
The purpose of this utility model provides that a kind of hardness height, wear resistance are strong, the Injection Pump chromium plating plunger of long service life.
For realizing that the technological scheme that the purpose of this utility model provided is the improvement that former plunger is carried out, this plunger is made up of plunger bushing and plug core, its main feature is: have additional chromium coating on the working surface of plug core, in order to strengthen the intensity of plug core, the working life of improving plunger.
The Injection Pump chromium plating plunger of making according to such scheme, can increase by one to two times working life, and low cost of manufacture, all genus plug core working surfaces is worn and causes and scraps, through after its working surface is set up chromium coating, still can use, not only save raw material, and save man-hour and manufacturing procedure, cost is half of former processing.
Description of drawings:
Utilize accompanying drawing to further describe embodiment of the present utility model below;
Fig. 1 is the structural representation of plug core in the utility model;
Fig. 2 is the structural representation of plunger bushing in the utility model.
Embodiment:
Referring to Fig. 1, Fig. 2, this plunger is made up of plunger bushing 2 and plug core 1, plug core 1 is contained in the plunger bushing 2, and cooperate with plunger bushing 2 and to move back and forth, on the working surface of plug core, to have additional chromium coating 1-1, in order to improve the hardness of plug core, reach the enhancing plunger wear resistance and the purpose in working life with this.
Claims (1)
1, a kind of Injection Pump chromium plating plunger is made up of plug core [1] and plunger bushing [2], it is characterized in that: have additional chromium coating [1-1] on the working surface of plug core [1].
