Operation steps of metal hydraulic packer

Various models of equipment suitable for manual valve operation of metal packer and hydraulic packer:

（1） When the four manual directional valve handles are in the middle position during no-load operation, start the motor. At this time, the high-pressure oil returns to the oil tank through the valve, the system is unloaded and the oil cylinder does not work.

（2） Under the door cover, push the valve handle of the door cover cylinder forward, and the door cover cylinder pushes the door cover to close, so as to carry out primary compression on the materials. Insert the lock head into the lock head sleeve and lock the door cover so that it does not float upward. When the indicated pressure reaches the system pressure, turn the handle to the middle position and unload the system.

（3） After the inlet valve cover of the side pressure cylinder is closed in place, pull the handle of the side pressure cylinder valve to the front position. The high-pressure oil enters the rear chamber of the side pressure cylinder through the side pressure cylinder valve to push the piston forward, and the side pressure head advances to compress the material in the secondary position. Pull the handle to the middle position after the cylinder stroke is in place (the pressure indication reaches the system pressure).

（4） After the pressure cylinder at the inlet side of the main pressure cylinder moves forward in place, pull the valve handle of the main pressure cylinder to the front position. The main pressure cylinder drives the main pressure head forward to carry out final compression on the materials. The materials are finally compressed and formed here. After the pressure indication value reaches the system pressure, keep the pressure for 3 ~ 5 seconds, pull the handle to the middle position.

（5） In return, pull the valve handles of the main pressure cylinder and side pressure cylinder to the back position in turn. The main and side pressure cylinders return. After the return is in place, turn the valve handle of the door cover cylinder to the middle position. The piston rod drives the slider to pull out the lock and open the door cover.

（6） First pull the handle of the cylinder valve to the front position, and then pull the handle of the cylinder valve of the door cover to the back position. The bag turning mechanism works to turn the pressed bag block in the compression chamber into the discharge box and remove the bag block.

（7） Turn the cylinder handle back to the valve cover position, and then turn the valve cover back to the valve cover position.

（8） Stop turning the handle of the turnover cylinder valve to the middle position, and then turn the handle of the door cover cylinder to the middle position, and the turnover cylinder stops working.

Precautions for operation steps of metal hydraulic packer:

1. Except that two valves need to be operated for bag turning and bag turning reset, only one valve needs to be operated for other actions.

2. When each action is in place, the valve handle needs to be restored to the middle position.

3. When turning over and resetting the package, pay attention to the return of the main pressure cylinder and side pressure cylinder so that they do not affect each other. Pay attention to the opening and closing state of the door cover. Do not turn the package when the door cover is closed to avoid damaging the machinery.

4. When feeding, pay attention to the feeding amount to avoid the disadvantage that the package is too long due to too much material, so that the package cannot be turned into the discharge box.
