The utility model is further provided with: the plunger is cast with a wear layer on the exterior.
By adopting the technical scheme, the abrasion-resistant layer is cast outside the plunger, so that the abrasion resistance of the outside of the plunger is effectively improved.
The utility model is further provided with: the wear-resistant layer is made of alloy steel.
By adopting the technical scheme, the wear-resistant layer is manufactured by adopting the alloy steel, so that the friction resistance of the wear-resistant layer is increased, and the problem of damage and breakage is avoided.
The utility model is further provided with: the plunger is internally cast with a compression resistant layer.
Through adopting above-mentioned technical scheme, through casting in the inside of plunger has the compressive layer, realize increasing the toughness of the inside of plunger, avoid appearing the plunger because of the problem that the fracture appears in the stress.
The utility model is further provided with: the compression-resistant layer is made of spring steel.
By adopting the technical scheme, the anti-wear capacity of the plunger is increased by adopting spring steel to manufacture the anti-compression layer.
The utility model is further provided with: the other ends of the sliding grooves extend to the left side of the two sealing rings.
Through adopting above-mentioned technical scheme, through extending the other end of a plurality of spouts to the left side sealing washer in two sealing washer, avoid striking the problem of sealing washer when using, effectively improve the life of plunger.
The beneficial effects of the utility model are as follows:
1. according to the utility model, the sliding grooves are uniformly formed in the peripheral side of one end of the plunger, so that the plunger is matched with the sliding rod correspondingly cast by the high-pressure plunger pump, the plunger cannot rotate or incline when in use, and the problem that the plunger is broken due to overlarge internal stress is avoided;
2. according to the plunger, the wear-resistant layer is arranged outside the plunger, the compression-resistant layer is arranged inside the plunger, so that the wear resistance of the plunger is improved through the wear-resistant layer outside the plunger when the plunger is used, and the toughness of the plunger is improved through the compression-resistant layer, so that the problem of breakage is avoided, and the service life of the plunger is effectively prolonged.
