Abstract

The invention provides a dual-hardness piston for a mud pump and a preparation method thereof, which specifically include: heating, defoaming, and adding a first raw material to a root material according to a first process flow, and pouring the treated root material into piston steel At the root of the core, the first root temperature value of the root material is obtained, and the second root temperature value of the root material is obtained after a first preset time; the heating layer is controlled to pour according to the first heating temperature value. The mold is heated and treated; the skirt material is heated, degassed and treated with the addition of the second raw material according to the second process flow, and the treated skirt material is poured to the skirt of the piston steel core; the heating device is controlled according to the first The heating temperature value is used to heat the first heating time; after the first heating time, the heating of the heating layer is stopped, and after the second preset time, the piston steel core for pouring the root material and the skirt material is demolded and vulcanized.

Description

technical field [0001] The invention relates to the technical field of manufacturing, in particular to a dual-hardness piston for a mud pump and a preparation method thereof. Background technique [0002] The application of the piston is very extensive, mainly used in the reciprocating motion of various pumps in the fields of oil drilling, construction machinery, mining equipment, etc. The suction and discharge of the mud pump is through the linear reciprocating motion of the piston in the cylinder liner, and the outward conveying is relatively high. pressure. In the drilling pump, the piston is subjected to high temperature, high pressure and high corrosion working environment. It is a key part and a high wear part, and it is the weak link of the drilling pump. Usually the service life is 200~300 hours. Once the piston fails, it cannot seal the mud leakage, and the cost of stopping the pump and replacing it is very high. The main reason for the inability to seal the mud i...
