          The plunger pump is the main equipment of the hydraulic system. It relies on the reciprocating type of the plunger in the cylinder to change the volume of the sealed working chamber to complete oil absorption and pressure. The plunger pump moves back and forth in the cylinder block with a large amount of movement, and needs to withstand unlimited friction during the working process. Therefore, the requirements for plunger pumps have higher hardness, wear resistance and service life, and at the same time have higher precision, and the selection of quenching heat treatment can meet the process requirements of plunger pumps. Quenching is a heat treatment technique in which steel is heated to a temperature higher than the critical temperature AC3 or AC1 and maintained for a period of time to make it fully or partially austenitized, and then when the cooling rate is greater than the critical cooling rate, the martensite is quickly cooled to below ms. Quenching technology is widely used in modern machinery manufacturing, the main parts of machinery, especially the mechanical parts used in automobiles, airplanes and rockets, just quenching. The above is about the working principle of the quenching heat treatment of the plunger pump, do you understand it?
