For the cylinder block, in order to improve its hardness and wear resistance, machining accuracy and surface finish, we select high-strength substrate, adopt precision casting, high-precision turning processing method and metal surface mirror processing technology, as well as special carbonitriding heat treatment process for cylinder body surface, which has excellent surface hardness, mechanical strength, machining accuracy, surface finish and Wear resistance and other technical indicators.

对于活塞密封组件，主要是提高其耐磨加工精度，自润滑性和适当的韧性，特别是在适当的过盈配合下确保超高压气体的良好密封。同时，由于润滑剂污染高纯度气体，活塞密封组件应具有良好的自润滑性。我们对数百种材料进行了比较和测试，并使用了特殊的加工技术来达到上述技术要求。

For piston seal components, it is mainly to improve the wear-resistant machining accuracy, self-lubricating property and proper toughness, especially under the appropriate interference fit to ensure the good sealing of ultra-high pressure gas. At the same time, because the lubricant pollutes the high purity gas, the piston seal assembly should have good self lubrication. We compared and tested hundreds of materials and used special processing technology to meet the above technical requirements.

使用异型缸体成型加工技术，超高压和强气体的密封存在很大的技术难关，在我国现有的材料和工艺条件下，要实现气缸体和活塞的良好密封，必须增加密封件的数量和干扰与气缸体。然而，这将导致润滑性的困难，导致其工作可靠性降低，使用寿命缩短，以及设备产生的热量突然增加，甚至在严重情况下燃烧相关部件和设备。

There are great technical difficulties in the sealing of ultra-high pressure and strong gas by using the forming technology of special-shaped cylinder block. In order to achieve good sealing of cylinder block and piston, the number of seals and interference with cylinder block must be increased. However, this will lead to difficulties in lubricity, resulting in reduced reliability, shortened service life, and sudden increase in heat generated by the equipment, and even combustion of related components and equipment in severe cases.

采用可更换部件的可更换结构，在气缸体和活塞体变为锥形之后，气缸体和活塞头将在运动过程中接触，碰撞和挤压。由于结构和材料的原因，高压缸体在超高压和摩擦高温的作用下接触。零件会很快磨损。

With the replaceable structure of replaceable parts, the cylinder block and piston head will contact, collide and squeeze in the process of movement after the cylinder block and piston body become conical. Due to the structure and material, the high pressure cylinder block contacts under the action of ultra-high pressure and high temperature of friction. Parts wear quickly.

由于缸体和活塞头与活塞头接触并且不与密封组件接触并且与密封组件匹配，因此工艺要求相对较低，并且该部分可以与其他部分分离。缸体和单独加工成可更换部件。

Since the cylinder block and piston head are in contact with the piston head and do not contact with the seal assembly and match the seal assembly, the process requirements are relatively low and this part can be separated from other parts. The cylinder block and are separately machined into replaceable parts.
