Explosion-proof junction box installation and use method
Tools required to install an explosion-proof junction box: screwdriver, tape, spare equipment, wiring nut. The installation method is as follows:
The first step: first cut off the power supply, please remove the corresponding fuse or trip the corresponding circuit breaker. For your safety, you can also operate the main switch to cut off the main power in the workshop.
Step 2: In most factories, there are two wires in the circuit. Connect the black wire to the black wire, the white wire to the white wire, and connect the remaining ground wire (see the Explosion-Proof Distribution Box Manufacturer Wiring Color Code Description and Distribution Box Recommended Installation Procedure). Connect with a wire nut and check for stability after connection.
Step 3: Check the wires, read the manufacturer's instructions, and carefully insert all the wires into the junction box (metal or plastic box for electrical connections).
Step 4: Connect the distribution box to the junction box or hook according to the manufacturer's instructions.
Step 5: Restart the circuit and test the installation.
Classified from the finished structure of the valve, it is usually divided into a whole valve, a double metal butt welding valve and a hollow sodium filling valve.The additional process is usually top soldering, top surfacing, cone surfacing, surface nitriding, surface chrome plating, and the like.The valve is an important part of the engine. The function of the valve is to specifically input air into the engine and exhaust the burned exhaust gas.
From the structure of the engine, it is divided into an intake valve and an Exhaust Valve. The function of the intake valve is to draw air into the engine and mix and burn with the fuel; the function of the exhaust valve is to discharge and dissipate the burned exhaust gas.
