Performance Parameters Calculation And Optimization Based On MATLAB In The Micro Porous Seals

Laser processing porous seals is a kind of new type sealing, it is in the common mechanical seal face of a micron grade in processing small pit hole, can realize non- contact, has the good lubrication performance and sealing performance.However, at present of laser processing porous seals research reported. The few This article through the establishment of laser processing porous seals, the theoretical analysis model by using the finite difference method is used to solve Reynolds equation, get in a given condition leakage, friction power consumption, etc, and the sealing per- formance parameters numerical analysis of different microporous depth, micro hole depth and microporous density on the seal performance parameters, get the influence law of microporous depth, micro hole depth and microporous density of the best value. The main research contents and conclusions are as follows:1.Established laser processing porous seals fluid dynamics analysis model, based on assumptions, a hole "liquid membrane pressure distribution throughout the seal surface can be characterized the liquid membrane pressure. Will dimensionless parameter, the finite difference method of laser processing porous seals performed exhaustive analysis and parameter research, and use of MATLAB computer software got liquid membrane pressure, leakage, friction power consumption, etc NengCan sealing.highet numerical value2.Of laser processing porous seals pressure of liquid membrane were studied. Through theoretical calculation and analysis, studies the structure parameters microporous radius, micro hole depth and microporous density than the influence of liquid membrane pressure. Results show that, given the conditions of micro hole depth, and microporous depth and micro hole density is optimized, can make the end of liquid membrane between pressure to achieve the best value3.Theoretical derivation got laser processing porous seals leakage rate formula, and theoretical calculation and analysis, and the results show that: micro hole depth and microporous density on the seals the leakage between has very big effect. Therefore, in order to increase seal dynamic pressure effect, reduce the energy consumption and reduce leakage, micro hole depth and microporous density should choose a suitable value 4.Through the calculation formula of friction consumption have got the best, analyzes microporous structure parameters for laser machining, porous seals engineering optimization design provides the reliable theory basis.
