Checking the relief valve spring during use can adjust the pressure of the entire system. If the adjustment is too tight, the time of use will cause the system pressure to increase, and then the sound and vibration during operation will become very serious, which directly leads to the bearing damage. Early wear is followed by the V-belt. Its shortening force is related to the amount of oil supply. If the shortening force is too small, the oil supply will decrease sharply, but if the shortening force is too large, the load received by the bearing will increase. Larger, this will also lead to early wear of the bearing and shorten the service life. However, if the time when the force is too large, the load received by the bearing will increase a lot, which will also lead to the early wear of the bearing.
The pipeline of the tanker and the tank installation are generally 1.5-inch galvanized pipes. The flanges of the pipeline should be cross-connected with wires. The entire tank and piping system should be in a good grounding condition. After the oil pipeline is laid, it should pass through Withstand voltage test to see if there is leakage. The oil pipeline should have an inclination of not less than 0.002. The diameter of the oil tank vent pipe is not less than 1.5 inches, the height is not less than 4 meters, and the right angle elbow should not be used as far as possible at the bend of the oil pipeline.
The requirements for the burial of the oil tank oil pipeline are that the top of the tank should be less than 700 mm above the ground, and the oil pipeline should be less than 500 mm above the ground. The bend angle of the oil pipeline should be as few as possible. The horizontal separation between the tanker manufacturer and the underground tank should not exceed 50 meters. The vertical separation between the lower surface of the tank and the fuel inlet of the tanker should generally not exceed 5 meters. The triangle valve between the suction pipe of the machine must be fitted with an oil-resistant gasket.
The main power switch of the fuel dispenser should be installed indoors, and the switch should be confirmed according to the current when the motor starts (about 6A). The power cord should be a two-time maintenance cable with a four-core multi-strand copper core with good oil resistance and corrosion resistance. When using a single-phase motor, the user power cord should have a cross-sectional area of not less than 6 mm.
When cleaning the tanker accessories filter, turn off the tanker power supply and pour the remaining oil in the filter into a safe container. When installing, check whether the outer gasket is damaged. When tightening the compression nut, the upper end of the filter body should enter the outer sealing gasket groove of the filter tray to ensure that the filter body and the filter tray are tightly sealed. The filter body cannot be rotated during disassembly and installation, only the compression nut can be rotated to avoid damage to the outer sealing gasket. After tightening, there should be no leakage on the contact surface of the outer sealing ring and the filter receiving plate. In order to avoid misoperation, after cleaning the filter each time, you should turn on the oil and check it. After confirming that the filter is securely installed, close the door of the refueling machine. Because the content of impurities in the oil of different gas stations is quite different, the filter The cleaning cycle of the filter cannot be clearly specified. When the flow rate of the dispenser is reduced, please clean the filter. If the flow rate is still abnormal after cleaning, please check whether other components affect the flow rate.
