AI Technical Summary

Technical Problem

Existing technologies for testing the service life of drilling pump cylinder liners and pistons suffer from high energy consumption, high investment, insufficient safety, and long testing cycles, making it impossible to effectively assess the service life of vulnerable parts.

Method used

A drilling pump cylinder liner and piston service life test system was designed, including test components, booster pump, pressure regulating device and data acquisition and control cabinet. By simulating the actual working conditions of the drilling pump, the system can achieve efficient service life testing of the cylinder liner and piston. It adopts a skid-mounted structure, and the load is only about 10% of the rated working conditions of the drilling pump. It has a high degree of automation and can be operated unattended.

Benefits of technology

It improves testing efficiency, reduces energy consumption and costs, ensures safety, enables rapid and efficient evaluation of cylinder liner and piston life, reduces the labor intensity of operators, and achieves flexible test sites and efficient test results.
