| description | The invention discloses a powder metallurgy combined sintering type plunger pump cylinder body and a preparation method thereof. According to the method, firstly, the plunger pump cylinder body undergoes parting, and is divided into two parts, namely, a high-strength cylinder head and a powder metallurgy cylinder main body, and the high-strength cylinder head and the powder metallurgy cylinder main body are welded into a whole through a powder metallurgy combined sintering process after being assembled, wherein the high-strength cylinder head is made of high-strength steel or other high-strength metal materials, the rest of the cylinder body (namely, the powder metallurgy cylinder main body) which comprises a cylinder body wall and a plunger hole is made of powder metallurgy materials. Inthe sintering process, copper infiltration materials infiltrate into powder metallurgy cylinder main body materials, so that the compactness is improved, and the anti-leakage requirement is met; and in addition, through the w |
