Description
Technical Field
The invention relates to the technical field of microstructure processing, in particular to a device and a method for processing a microstructure on the surface of a water lubrication bearing of a submersible pump for fire fighting.
Background
With the continuous development of economy and society, the requirements on the rescue equipment for the fire protection are higher and higher. The construction of the fire-fighting rescue equipment is greatly developed, and the construction is an important guarantee for supporting the lifting of the fire-fighting emergency rescue capability. In towns, villages and fire-fighting vehicles, fire sites not easy to reach or temporarily get water, the portable submersible pump for fire-fighting can supply or supplement fire-fighting water by utilizing water sources near the fire sites. As one of the key friction and wear parts of the submersible pump for fire control, the performance change of the water lubrication bearing affects the operation reliability of the whole pump. The improvement of the tribological performance and the service life of the submersible pump bearing has important significance for improving the hydraulic performance of the whole machine.
The mechanical system is not separated from the kinematic pairs, and the friction, abrasion and lubrication performance among the relative kinematic pairs have direct influence on the operation efficiency, the service life and the like of the mechanical system. Friction-induced wear is a major cause of mechanical equipment failure. In order to reduce frictional wear of the contact surfaces, improve reliability and service life when operating under extreme conditions, various antifriction means have been proposed. The first is chemical antifriction: (1) the direct addition method is a method of directly adding components such as a solid lubricating phase and a metal-based binding material to a substrate to prepare a coating layer, (2) the in-situ synthesis method is a method of generating a new phase by utilizing a chemical reaction between elements or compounds, (3) a preparation technology, chemical solution deposition (electroplating and electroless plating), spraying, conversion coating (micro-arc oxidation and sol-gel), powder metallurgy, vapor deposition and high-energy beam cladding. The second is physical antifriction: (1) gradient nanostructure: firstly, self nanocrystallization, namely plastic deformation (surface mechanical treatment) of a surface layer, secondly, non-self nanocrystallization (physical chemical deposition and the like), the gradient nanostructure has excellent characteristics in the aspects of strength-toughness synergy, fatigue resistance and the like, a new strategy is provided for antifriction modification, and (2) a surface texture technology is adopted, wherein the surface texture technology is to machine a pit or groove array with a certain shape, size, area rate and arrangement rule on the surface of a material. Textured surfaces have better material surface properties than non-textured surfaces. The commonly used surface texture technology at present comprises laser processing, electrolytic processing, chemical etching, electric spark processing, photo etching, ultrasonic vibration auxiliary processing and other technologies. Related research at home and abroad shows that the surface texture is an effective means for improving the tribological characteristics of the surface interface, can realize the self-lubricating effect on the surface of the material, and can reduce mechanical equipment failure and energy consumption caused by friction and wear. Therefore, the improvement of the lubrication antifriction effect by utilizing the functional surface micro-nano texture is becoming an important research direction, and the method and the device for manufacturing the functional surface micro-nano texture of the related water lubrication bearing have good economic benefit and social benefit.
Among the above surface texture processing methods, the laser processing technique is considered to be the optimal texture processing technique because of the characteristics of high precision, high efficiency, no pollution, good reliability, and the like. In the laser shock strengthening process, the peak pressure of shock waves is expected to be improved as much as possible, and full utilization of laser energy is ensured, so that the shock area needs to be accurately positioned, the normal line of the shock point is overlapped with the incident light beam, and a high-quality shock effect is obtained. However, in the process of machining the water lubricated bearing, it is very difficult to ensure that the laser time is perpendicular to the surface of the water lubricated bearing, so that the machining effect is not ideal, and burrs and chips exist.
