小型高纯度气体气驱增压泵改善工艺

发布时间:2019-06-21 16:47:44   发布人:http://www.sdjingtuo.com
小型高纯度气体驱动气体增压泵的开发触及资料构造和工艺的许多技术创新。 在消费时首先要对资料停止处置,为理解决高速挪动活塞和气缸体在超高压下的磨损,气密和自光滑问题,我们采用了特殊的资料和处置工艺。
The development of small gas-driven supercharged pumps with high purity touches upon many technological innovations in data structure and technology. In order to solve the problems of wear, air tightness and self-smoothness of high-speed moving piston and cylinder block under ultra-high pressure, we adopt special data and processing technology.
关于气缸体,主要是为了进步其硬度和耐磨性加工精度和外表光亮度,我们选用高强度基材,采用精细铸造,高精度车削加工办法和金属外表镜加工技术,以及气缸机身外表采用特殊的碳氮共渗热处置工艺,具有优良的外表硬度,机械强度加工精度,外表光亮度和耐磨性等技术指标。
With regard to cylinder block, the main purpose is to improve its hardness and abrasion resistance processing accuracy and surface brightness. We use high strength base material, fine casting, high precision turning method and metal mirror processing technology, as well as special carbonitriding heat treatment technology for cylinder body surface, which has excellent surface hardness, mechanical strength processing accuracy, surface brightness and brightness. Wear resistance and other technical indicators.
关于活塞密封组件,主要是进步其耐磨加工精度,自光滑性和恰当的韧性,特别是在恰当的过盈配合下确保超高压气体的良好密封。同时,由于光滑剂污染高纯度气体,活塞密封组件应具有良好的自光滑性。我们对数百种资料停止了比拟和测试,并运用了特殊的加工技术来到达上述技术请求。

As for piston seal assembly, it is mainly to improve its wear-resistant processing accuracy, self-smoothness and proper toughness, especially to ensure the good sealing of ultra-high pressure gas under the appropriate interference fit. At the same time, the piston seal assembly should have good self-smoothness because the smoother contaminates the high purity gas. We stopped comparing and testing hundreds of kinds of data and used special processing technology to meet the above technical requirements.
运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,在我国现有的资料和工艺条件下,要完成气缸体和活塞的良好密封,必需增加密封件的数量和干扰与气缸体。但是,这将招致光滑性的艰难,招致其工作牢靠性降低,运用寿命缩短,以及设备产生的热量忽然增加,以至在严重状况下熄灭相关部件和设备。
There are great technical difficulties in the sealing of ultra-high pressure and strong gas by using the forming and processing technology of special-shaped cylinder block. In order to complete the good sealing of cylinder block and piston, it is necessary to increase the number of seals, interference and cylinder block. However, this will lead to difficulties in smoothness, lower reliability, shorter service life, and sudden increase in heat generated by the equipment, so as to extinguish the relevant components and equipment in serious conditions.
采用可改换部件的可改换构造,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。由于构造和资料的缘由,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, after the cylinder body and piston body become conical, the cylinder body and piston head will contact, collide and extrude in the course of movement. Due to the structure and data, the high pressure cylinder block contacts under the action of ultra-high pressure and high friction temperature. Parts will wear out 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,因而工艺请求相对较低,并且该局部能够与其他局部别离。缸体和单独加工成可改换部件。
Because the cylinder block and piston head are in contact with the piston head and do not contact with the sealing component and match with the sealing component, the process requirement is relatively low, and the part can be separated from other parts. Cylinder block and individual machined into replaceable parts.
