Abstract  Oil-trap results from the work principle of gear pump, and it directly influences the performance and lifespan of gear pump. Reducing pressure in trapping area is of great importance to enhance performance of gear pump. Therefore, how to measure pressure in trapping area is a problem confronting researchers.Design of experimental system is carried out, and experiments are conducted. The results indicate that this system can meet requirements well.

Key words： gear pump      trapping      pressure      experiment
