ection is small, pump suction is large; vice versa, large returned oil low suction distance. Diagram 2-5: Suction flow of vane pump Suction capacity of pump is restricted not only by its structure but also by the oil physical trait and pipeline. Under a certain temperature, air pocket phenomenon of oil will generated when vacuum reaching a given degree, so that the pump can’t suck oil normally. At high oil level, large resistance from pipeline, much higher vacuum pressure occurs at the inlet of pump; the higher temperature the more likely create air pocket. The phenomenon is likely to appear given the oil is gasoline. The phenomenon of cavitation is generated when partial pressure at inlet of pump is low than air pressure, the dissolved gas in oil begin separate out, and oil start gasifying vigorously as pressure getting down, reaching saturation pressure. The normal working of pump is affected due to a great of foam damaging the continuity of liquid flow. Fuel dispenser is likely come out any oil or work with large noise as the cavitation is severe. Components will be damaged in this long phenomenon. At same time, oil vibration is increased so that the accuracy become down, as well as shorting service life of hydraulic components. The correlation between liquid saturation and gas pressure is illustrated in diagram 2-6. Diagram 2-6: Relations among temperature, steam pressure and liquid saturation Diagram 2-6 shows gasoline more likely to Air area than water and coal oil under the same pressure along with temperature increasing; under the same temperature the more vacuum pressure the earlier in air-area. There are two aspects that should be considered to prevent cavitation in pump inlet. One is that the design parameter of pump should be rational. The other is that pipeline should be installed scientifically. The effect of hy fuel dispenser draulic fuel dispenser pipe to fuel dispenser’s suction capacity will be introduced in detail. To understand the principle of cavitation a fuel dispenser nd causation of affecting pump suction capacity is
