operate motor. If it still don’t move or slowly run, electric circuit or motor should be inspected. If not the rotor of pump maybe locked. Carefully check and cleanse oil strainer. If failure still exists after the above inspection, overflow valve should be checkup. In case that valve core jam, shut down incompletely or lose in valve seat the oil in high pressure area ove fuel dispenser rflow into negative area, resulting in no delivery or inefficient discharge. Taking out valve core and spring so as to clean dirty, inspect valve seat at same time. If valve seat is loose re-fix it through fuel dispenser oil-resistant glue or change a new pump. When find scrap of spring and graphite, washing overflow valve is must, changing broken parts if necessary. If found rotor is stuck there would be several reasons related, such as spring broken, long vane, vane segment, lose bolts at top cover, etc. reassembling after overcome these reasons. Some manufacturers adopt new spring material evading broken. The lose match of rotor and axis of pump also result in no delivery or inefficient discharge. This situation will be overcome fuel dispenser by changing rotor. After the above check and examine still find any rotor stuck or overflow valve abnormal, it is suggestive that vane abrasion is extensive, broken and spring damaged. Much abrasive vane can not successfully segment high and low pressure area, resulting no delivery or inefficient discharge as the areas exchange. The broken vane or spring not only cause flow trouble but also increase noise as whole. Furthermore, if they flow into other inner components may result in new failure. The solution to this is to change new vane or spring and clean out broken piece. It is suggestive that change all vanes if fuel dispenser have operated long time. Changing a new pump overcomes too large abrasion between frame and rotor. To check whether a leakage occurred in pine between fuel dispenser and tank, different diameter of pipe connection, bottom valve stuck or leakage. Abnormal noise and vibration The reason of
