Checking the shifting and on-duty operations of the tanker equipment in the tanker equipment; inspection method: listen to whether the working sound of the tanker is normal; see if there is leakage or deformation at the connection of the tanker shell and the whole machine, and whether the display is normal; Smell, whether there is a peculiar smell. Daily maintenance. When the fueler is handing over shifts and when refueling is idle, he wipes the shell of the fueler to make it clean and free of dust and dirt; often open the door of the fueler to wipe the dust inside the machine; fill the pump bearings, counter bearings, and transmission parts with oil; belts Whether it is loose, whether the wiring is loose.
The metering volume of the oil flowing through the fuel dispenser components generally uses a positive displacement flowmeter. A certain amount of oil passing through will cause a certain displacement of the transmission shaft, and correspondingly, the sensor will output a certain number of pulses.
The electromagnetic valve. The main effect of the components: solve the problem of overshoot during quantitative refueling to improve the accuracy of quantification; for the submersible pump tanker, it also has the effect of closing the oil pipeline when it is not refueling. Self-sealing oil gun. The effect of the components: It is used for filling oil, and when the container is full, the oil gun is actively closed, which is a kind of anti-overflow equipment.
The shortening force of the tanker equipment is related to the size of the fuel supply. If the shortening force is too small, it will cause a sudden decrease in fuel supply. But if you shorten the time when the force is too large, the load received by the bearing will increase a lot. This will also lead to premature wear of the bearing and shorten the service life. The fuel dispenser can adjust the pressure of the entire system. If the adjustment is too tight, the time used will cause the system pressure to increase, and then the sound and vibration during operation will become very serious.
The single-unit pipeline of the tanker should generally be a 1.5-inch galvanized pipe. The flanges of the pipeline should be cross-connected with wires. The entire oil tank and piping system should have an outstanding grounding state and undergo a pressure test. The corners of the pipeline should be as few as possible. The horizontal distance between the tanker and the underground tank should not exceed 30 meters, and the vertical distance between the lower surface of the tank and the tanker inlet should not be more than 6 meters, so as not to affect the suction range. The triangular flange between the inlet of the oil pipeline and the suction pipe of the machine is fitted with an oil-resistant gasket.
