l type fuel dispenser. Article I Failure judgment and troubleshooting Normal operation without fuel 1.1 If motor turn reversely, power phase would be wrong; if delivery V belt loose and rupture, regulating expansion wheel or replacing V wheel. 1.2 Vapor separator failure If triangular gasket of inlet and filter washer is loose or broken, air would flow into hydraulic system. To solve this kind of leakage is to tighten bolt or change a new washer. Serious jam in filter, including cone-shaped net, should clean waster or change a new filter net. If the check valve of vapor separator is clamped, resulting in no delivery, disconnect check valve and clean it fuel dispenser , finally reassemble. Incorrect installation of floater or waster under sealed gasket in vapor separator, oil would be discharged from exhausting pipe. To clean waster and reassemble, change a new floater when find serious damage or not being homocentric. If small floater is leak or fall down, high pressure chamber can reach high pressure so that no delivery in fuel fuel dispenser dispenser. Broken upper cover gasket also result in the communication between two chambers of high pressure and vapor separator so that no discharge out of fuel dispenser. 1.3. Pump trouble Substance clamped between valve core and valve seat in overflow valve result in oil circulate within pump. Taking out valve core and clean feculence, fix falling valve seat, changing pump when necessary. Due to high speed rotation some vane abrasion or damaged the inner pressure of pump is reduced largely, even lost suction capacity. Replacing damaged vane after cleaning feculence. Broken gasket or reverse installatio fuel dispenser n in the surface between pump and vapor separator result in the communication of high and low pressure chambers so that no oil is discharged. Rotor and stator are loose, making pump axis run without loan. It is need to replace rotor or pump. Long operation increases the clearance between inner and outer gear, resulting large interior leakage and suction capacity declining
