小型高纯气体驱动增压装置的研制涉及哪些技术?

  小型高纯气体驱动增压装置的研究与开发涉及到材料结构和技术上的诸多技术创新。
  The research and development of small high purity gas driven supercharger involves many technological innovations in material structure and technology.
  1. 材料加工技术
  1. Material processing technology
  (1)气缸体,是提高加工精度和表面光洁度,和它的硬度、耐磨性,选择高强度基材,采用精密铸造,精密镜面加工方法和金属表面处理技术,并采用了一种特殊的缸体表面碳氮共渗热处理工艺,使其优秀的加工精度表面光洁度,机械强度、表面硬度、耐磨性等。全面的技术指标。
  (1) the cylinder block is to improve the machining accuracy and surface finish, and its hardness and wear resistance. High strength base materials are selected, precision casting, precision mirror machining and metal surface treatment technology are adopted, and a special surface carbonitriding heat treatment technology is adopted to make its excellent machining accuracy surface finish, mechanical strength, surface hardness and wear resistance. Comprehensive technical indicators.

  (2)对于活塞密封总成,主要是提高其耐磨性加工精度、自润滑性和适当的韧性,尤其要保证在适当的过盈配合下,能够实现良好的超高压强气密封。同时,由于润滑油会污染高纯气体,活塞密封装置应具有良好的自润滑性。我们对数百种材料进行了对比测试,并采用特殊的加工工艺来达到上述技术要求。
  (2) for the piston seal assembly, it is mainly to improve its wear resistance processing accuracy, self lubrication and appropriate toughness, especially to ensure that under the appropriate interference fit, it can achieve a good super high pressure strong gas seal. At the same time, because the lubricating oil will pollute the high purity gas, the piston sealing device should have good self lubrication. We have tested hundreds of materials and adopted special processing technology to meet the above technical requirements.
  2. 异型缸体的成形与加工技术
  2. Forming and processing technology of special cylinder
  超高压、强气的密封存在较大的技术难点:在我国现有的材料和工艺条件下,要实现对缸体和活塞的良好密封,需要增加密封的数量和对缸体的干扰。然而,这样会给润滑带来困难,导致工作可靠性下降,使用寿命缩短,同时设备的发热也会增加,甚至在严重情况下会烧坏相关部件和设备。我们创造性地把缸体和活塞体从一个缸体改造成一个锥体,并对密封结构做了相应的改进,使密封从线接触到面接触,机组密封总成的密封效果提高了200%~500%。在反复试验的基础上,科学确定了密封元件的数量,并很好地平衡了密封润滑、磨损和散热的技术要求。
  There are great technical difficulties in the sealing of ultra-high pressure and strong gas: under the existing material and process conditions in China, in order to achieve a good sealing of the cylinder block and piston, it is necessary to increase the number of seals and the interference to the cylinder block. However, this will bring difficulties to lubrication, reduce the reliability of work, shorten the service life, and increase the heating of equipment, even in serious cases, it will burn relevant parts and equipment. We creatively transformed the cylinder and piston body from a cylinder body to a cone, and made corresponding improvements on the sealing structure, so that the sealing effect of the unit's sealing assembly increased by 200% ~ 500% from line contact to face contact. On the basis of repeated tests, the optimum number of sealing elements is determined scientifically, and the technical requirements of seal lubrication, wear and heat dissipation are well balanced.
  3.易磨损零件的可更换结构
  3. Replaceable structure of easily worn parts
  缸体和活塞的身体改变锥,缸体和活塞头在运动的过程中会产生接触,碰撞和挤压,由于结构和材料的原因,在高压力和摩擦力的作用下高温、高压缸体接触部分很快就会磨损。对于这个问题,我们不能盲目地从材料上考虑,而是要改变思维方式,从构件结构上攻击。我们注意到,由于缸体与活塞头接触容易磨损的零件不与密封总成接触,工艺要求相对较低,这部分零件可以与缸体的其他零件分离,单独加工成可更换零件。
  The body of the cylinder and the piston changes the cone, and the cylinder and the piston head will have contact, collision and extrusion in the process of movement. Due to the reasons of structure and materials, the contact parts of the high-temperature and high-pressure cylinder block will wear quickly under the action of high pressure and friction. For this problem, we should not blindly consider from the material, but change the way of thinking and attack from the component structure. We have noticed that the parts that are easy to wear when the cylinder block contacts the piston head are not in contact with the seal assembly, so the technological requirements are relatively low. This part can be separated from other parts of the cylinder block and processed into replaceable parts separately.
