Study on Sealing Performance of Submersible Pumps with Hydrodynamic Mechanical Seal

TANG Zhan-qi et al (School of Chemistry and Chemical Engineering,Beifang University of Nationalities,Yinchuan,Ningxia 750021)  
[Objective] The study aimed to discuss the influence of the depth and number of hydrodynamic groove on the sealing performance such as the leakage and liquid film stiffness of agricultural submersible pump.[Method] The hydrodynamic lubrication theory was applied on the design for the mechanical seal of the submersible pump and the hydrodynamic pressure effect could be produced through the skew line groove of the sealing surface to increase the life of the sealing device.The CFD technology was applied to establish the geometrical model and simulate the sealing performance so as to ensure the sealing process with a smaller seal leakage and larger liquid film stiffness as the optimal criteria and discuss the best sealing performance parameters of the depth and number of hydrodynamic groove to the leakage and liquid film stiffness etc.[Result] The externally mounted seal with inside skew line groove showed the obvious fluid dynamatic pressure effect and could generate the liquid film with the larger stiffness,which could set the seal surfaces apart,reduce the friction wear and could resist the more violent external condition change.The inside skew line groove could produce the upstream pumping effect and had samll seal leakage quantity,and when the groove number was 30 and the groove depth was 5-8 μm,the seal comprehensive effect was best.[Conclusion] The seal with the skew line groove had the advantages of small seal leakage quantity and great liquid film stiffness,etc.
