on and noise of pump, finding whether leakage between axis end and pump cover, checking the excessive jump and swing of V wheel that is called belt wheel past, but now defined as V wheel in GBT/10412�002 General V Wheel. Don’t use water and oil with water to debug or cleanse tank in case of the pump and components of fuel dispenser is rust. Meanwhile preventing freeze water affect the normal operation because of low temperature. Regularly inspect and cleanse strainer, especial after installation a pipeline. With the working time get long the waste in pipeline or tank decrease, the period of checking and cleanse should con fuel dispenser siderably lengthen. But don’t exceed one month. The strength of V wheel should be appropriate because low strength resu fuel dispenser lt in no oil discharge out or inefficiency. High strength, in another case, would increase the axis loan of motor and pump, fasting bearing abrasion of motor, pump and oil seal. Don’t adjust overflow valve to tight in case of increasing pump pressur fuel dispenser e so as to flux passing overflow valve, and well as noise, vibration and abrasion. Judgment for common failures Firstly, some failure analysis and correct judgment is necessary before maintenance. The principle of first analysis then disassemble, easy first is the basis to judge trouble. The common failure phenomenon of vane pump is that no delivery, inefficient flux, leakage, noise and abnormal vibration. They will be introduced one by one. No delivery or inefficient flux Apart from pump failure other component and pipeline trouble may also result in this phenomenon. Here only introduce pump failure and inspection method. Exterior inspection: to check motor that maybe don’t work, or rotate in opposite direction, or lose V wheel. Reversal result from wrongly connecting two phase wire in motor or power supply. Adjusting strength of V wheel or changing a new one deal with wheel slip. However, the reason that motor don’t work are several, either electric or mechanical failure. Disconnecting V wheel at first,
