fuel dispenser maintenance

(1) machine pump tanker oil separator that has the filter, which is made of copper mesh nets and blankets composed of a triangular side wall separator can remove the filter cover. Combination pump dispenser filters installed in the inlet. Submersible pump type automatic tank gauge systems with a special filter cartridge, open its cover to remove the filter. Filter regularly (at least once a month) cleaning with gasoline copper mesh cover, damage should be replaced, and remove dirt oil inside the machine, in order to protect the pump and flow meter.
(2) the pressure relief valve on the pump adjustment screw for adjusting the pump, thereby regulating the discharge of oil tank monitoring system. It has been adjusted at the factory. The long-term use, such as discharge oil declined, can the adjustment screw to tighten in order to increase the pressure of the pump, but not more than 0.3MPa, the exhaust oil to meet the requirements.
(3) a combination of a pump dispenser is only suitable for underground tanks, such as the use of high tank calibration software, exhaust pipe Mao phenomenon occurs, then be sure the exhaust pipe blocked.

Check periodically tighten the screws on the stopper on the filler pipe to prevent the injection tubing roots loose, damaged.
(5) Adjust the machine accuracy, according to relevant regulations.
(6) Check the electrical part must cut off the power, should not live overhaul. Open the box do not damage the surface explosion proof. Dust explosion cavity foreign body should re-install clean up clean, the cable seal should good, metal pads, gaskets can not be lost, no shortage of the number of screws, tighten the reliable, to ensure explosion-proof electrical component.
