Many people have very limited understanding of small fuel dispensers. Today, let's take a look at how to install the power supply in the tanker accessories and ask him, I hope you can have more understanding.
The main power switch of the tanker should be located indoors, and the switch insurance should be determined according to the current when the motor starts (about 6A). The power cord should be protected twice with five-core and multi-strand copper cores with good oil resistance and corrosion resistance.
When using a single-phase motor, the user's power cord should be a copper core sheathed wire with a cross-sectional area of not less than 6 square millimeters, otherwise it may cause the motor to fail to start or even burn out the motor. The use of single-strand wires and aluminum core wires is prohibited.
The connection line between the power distribution room and the fuel dispenser is buried in the casing to prevent the vehicle from rolling off the line. At the outlet of the cable passing through the hole of the tanker base, an open oil-resistant elbow is set to prevent oil dripping into the steel pipe and corroding the cable. The fire endangers the safety of the gas station.
The user's power cord is connected to the explosion-proof junction box of the fuel dispenser, which should correspond to the three-phase power supply and ground wire of the junction box of the machine. After the cable is put into the box, the screw plug should be tightened, and the cable must be clamped to ensure the explosion-proof of the junction box. performance.
If the oil pump is not turned correctly, just turn the A. b. Any two of the three phase lines of C can be exchanged. This issue needs to be implemented by the vendor.
The fuel dispenser should be equipped with a separate ground wire, and the test ground resistance should not be greater than 4 ohms.
