Based on a control method for described oil seal for crankshaft of engine leakage testing device, it is characterized in that:
Oil seal for crankshaft of engine to be detected fixed by step 1, clamping;
Step 2, inflation;
Step 3, maintenance fixation pressure;
Step 4, by detect whether have pressure change detect whether leak;
Step 5, be vented and show test results;
Step 6, take out oil seal for crankshaft of engine to be detected.
In described step 2, inner gas pressure is-18 to-22KPa.
In described step 2, inflation continues 5-9S, keeps fixation pressure to continue 4-6S in described step 3, and described step 4 detects and continues 4-6S.
Simple in oil seal for crankshaft of engine leakage testing device structure of the present invention, light and handy, on cost, manufacturing price is cheap, can effectively realize and meet need of production qualitatively.Not only reduce the disqualification rate of product, improve Employees ' Satisfaction Degree simultaneously, improve the quality of products, accelerate productive temp, improve the rate that comes into force.
