conducive to the failure that no oil is sucked. Don’t worry about the phenomenon of cavitation because its probability to occur is low, and the method to prevent it appearance would find when pipeline setting and the design and manufacture of pump. At present, manufacturers have achieved great progress in research to prevent cavitation in pump inlet. The phenomenon is avoidable. Stability The stability of pump is more important technical parameter, which is one of major labels measuring the performance of pump. The good stability of pump is low fluctuation in flow and slow increase of pulsant value as working long time. The 13.6 of JJG667-97 Liquid cubage flow meter stipulates that the flow rate fluctuation not exceed 2.5%, which is requirement for pump stability. Under same operating condition a good stability pump reduce the abrasion of hydraulic components so as to lengthen fuel dispenser’s service life. Moreover, it is conducive to reduce leakage of measure transducer and enhance the accuracy. Noise Noise is also a symbol of pump’s performance, which relate to fuel dispenser’s noise. The GB/T9081-2001 fuel dispenser Fuel dispenser for vehicle stipulates that the noise of fuel dispenser not exceed 80d B and the noise of pump no more than that of fuel dispenser, which is basic requirement for fuel dispenser. Noise is often created from pump of fuel dispenser, computeriz fuel dispenser ed fuel fuel dispenser dispenser in particular. The pump noise is largely depended upon its stability, cavitation, partial flow speed and oil abrasion, etc. High noise pollutes environment and wastes electricity so as to increase operation cost of filling station. Usage and maintenance Many domestic component manufacturers now produce vane pump, but their products vary from inner structure, choice of material, suction capacity, stability, service life, noise and so on. Thus failure presents largely different. Vane pump should often be inspected and maintained during the operation progress. Specific procedure is as followed: Often inspect the rotati
