Starting and operating procedures for electric pipe expanding machine

Starting and operating procedures for electric pipe expanding machine

1, Operating procedures for expansion tube machine

1. Before using the expansion tube machine, the power supply and wiring should be carefully checked to ensure that they are intact and safe, and corresponding preparations should be made.

2. When expanding the tube, it is necessary to cooperate with each other, concentrate and prevent accidents.

3. Pay close attention to the power display screen when expanding the tube, and do not overload it.

4. At the beginning of the expansion tube, do not touch the expansion head with your hands to prevent entanglement.

5. After completing the work, the power should be immediately turned off and the expansion tube machine should be placed back in its original position.

2, Safety operation requirements

1. The operator of the hydraulic expansion pipe machine must undergo training, master the equipment performance and operating techniques before they can operate independently.

2. Before use, check if the power supply voltage meets the requirements. The power supply is three-phase 380V. The equipment should be reliably grounded, and the phase and neutral wires should be accurately connected to the terminal block under the electrical cabinet.

3. Connect and lock the handle to the machine to ensure reliable plug connection.

4. Check that the hydraulic oil should be added to the specified liquid level, and the water level in the bottom water tank should be added above the specified minimum level.

3, Startup and operation procedures

1. Open the cabinet door and connect all circuit breakers inside the cabinet. Press the "Power On" button on the panel, the power indicator light will light up, and the text display will display a welcome screen.

2. Then enter the "Expansion Operation" screen. The "target pressure" in the current screen is the pressure that the user needs to set for expansion joint, which can be directly modified. Press the "ENT" key, the background color of the target pressure value in the text display will turn black, then press the "CLR" key, enter the desired value, and finally press the "ENT" key to confirm the desired value. The setting is complete.

3. Evacuate the air inside the high-pressure hose and expansion head. Operation method: Remove the hydraulic expansion head, with the handle mouth facing upwards, press the "pressure increase" button to discharge the bubbles inside the hose outward. After the hose medium overflows, click the "pressure decrease" button to stop pressurization. After filling the expansion head with medium, install the operating handle and tighten it.

4. Expansion tube operation method: Insert the expansion head into the tube hole that needs to be expanded. When the expansion head is inserted into the expansion position inside the tube, press the pistol switch on the operating handle (release after pressing). At this point, the "boost indicator" indicator light is on, and the machine starts the automatic expansion process. After the expansion pressure reaches the set value, the pressure increase stops and automatically enters the pressure decrease state, with the "pressure decrease indicator" indicator light on. After the voltage reduction is completed, the handle can be pulled out. At this point, the expansion joint of the pipe is completed, the expansion head is removed and inserted into another hole,

Proceed to the next work cycle.
