Small fuel dispenser vane pump use and maintenance:

In a small portable fuel dispenser use, it requires frequent inspection and maintenance vane pump.
First test machine and cleaning the auto fuel dispenser, can not use water or an aqueous oil tankers, in order to avoid the cracking damage pumps and other components of internal corrosion and low temperatures.
Secondly, you should regularly clean the filter, especially a newly installed machine and piping and even more so. With the increasing use of time, dirt tank and the pipeline will be reduced, the filter cleaning cycle can be extended, but generally should not exceed one month.
Again always check whether a flexible vane pump is running even with or without abnormal noise, shaft and pump cover at the leaks, pulleys for excessive runout and wobble like.
At the same time the relief valve spring can not be adjusted too tight, or make the system pressure, noise and vibration increases and exacerbate the pump bearing wear.
Finally belt tension should be appropriate, tensioning force is too small, the belt slippery, causing supply shortage or supply, belt is also easy to wear, the tension is too large, the motor shaft and pump shaft bear additional load (axial direction of the vertical axis) increases, could easily accelerate the motor bearings, pump bearings and seals wear.
