James is the purchasing director of one of our American Hydraulic customers. They are the top 3 in the construction machinery industry in the United States, and their market share is increasing year by year. In May last year, the MP550-HDD-18 cement delivery pump supplied by their company to a local construction company often failed to reach the rated value for the system pressure during use, and the oil pressure of the hydraulic system can only reach 12MPa. After disassembling the hydraulic system, the engineer found that the joint surface between the conical pilot valve body and the valve seat of the hydraulic relief valve was grinded out with a circle of uneven groove line with a depth of about 1mm for unknown reason. The hydraulic oil flowed back to the oil tank from this groove, and the hydraulic relief valve had no sealing function.
He wanted to see if AAK had a way to solve this thorny problem.
