Small fuel dispenser pump in order to avoid the matter failure to note what?

Caution Disassembly and reassembly of the small china fuel dispenser oil pump requires very close attention. The requirements of the pump seal, no leakage, the moving parts can move flexibly cable wiring, noise and vibration at work. So the various demands of the portable fuel dispenser is also very strict. For these considerations require more attention, as follows:
1, after the rotor assembly into the pump chamber, the application of hand (or stuck with a rigid shaft keyway hand) rotating rotor blades look carefully at whether the retractable blade slots, while viewing the rotor blade is higher. If higher rotor blades, the blades shall be polished. So that the rotor contour or slightly below the rotor.
2, before the service, it must be reliably cut off the power. Remove the belt from the pulley, so as to avoid accidental injury. Ready tipping the oil container to avoid oil pump and oil separator drain spilled everywhere. Finally, before you re-install the pump, use kerosene to clean all parts, do not allow any sticky dirt to avoid scratching the pump, resulting in a new fault.
