抽油泵的泵筒及柱塞的加工工艺
摘要：
本发明提供的抽油泵的泵筒及柱塞的加工工艺，其特征在于，其包括：将40Gr的碳素结构钢作为基体材料，并对所述基体材料进行冷拔或冷轧处理；将所述冷拔或冷轧处理后的基体材料进行人工时效热处理；将所述人工时效热处理后的基体材料进行乳白铬底层覆盖工艺；将所述乳白铬底层覆盖工艺后的基体材料进行激光熔覆表面处理；将所述激光熔覆表面处理后的基体材料进行纳米金刚石微粉电镀硬铬工艺。本发明实现了能提供一种可以有效提高抽油泵的使用寿命，提高抽油泵的防腐耐磨能力的抽油泵的泵筒及柱塞的加工工艺的目的。
摘要（英）：

The invention relates to a process for processing a barrel and a plunger of an oil pump. The process is characterized by comprising the following steps: carrying out cold drawing or rolling on a base material, wherein the base material is 40Gr-grade carbon structural steel; carrying out artificial ageing treatment and heat treatment on the cold drawn or rolled base material; covering the underlayer of the base material subjected to artificial ageing treatment and heat treatment with milk-white chromium; cladding the surface of the covered base material by laser; and plating the clad base material with nano diamond powder based hard chromium. By adopting the process provided by the invention to process the barrel and plunger of the oil pump, the purposes of prolonging the service life of the oil pump effectively and improving the corrosion and wear resisting capacity of the oil pump can be achieved.
