Power safety precautions for tile presses

Power safety precautions for tile presses

1. According to the regulations, the electrical equipment shall be inspected and maintained on time, and the unused electrical equipment lines shall be completely removed.

2. When the department is out of power, when it is less than 0.9 meters away from the electrical quantity inspection staff, dry wood rubber or insulation material shall be used for reliable temporary obstruction.

Third, when the conductive parts of the mechanical parts of the pressure tile are grounded, before the power is cut off, except for those who rescue the electric shock, they will not agree to approach, and leave the nearby 4 meters, leaving the room 1.8 meters away from the stride voltage damage.

4. When repairing the equipment of the pressing machine, pull down the switch and the knife. It is necessary to hang the warning sign “No closing, some people working” at the switch and the knife. On the covered fence of the charged equipment and the aisle where the passage is prohibited. Warning signs such as “stopping, high-voltage danger” should be hung, and the warning sign of “someone working here” should be hung at the workplace.

5. The electrician must know the type and function of the electrical circuit and electrical equipment in the workshop. The function of the electrical equipment is not fully understood, and it is forbidden to take risks.

6. The electrician should check the condition of cables, motors, electric consoles and other equipment on a daily basis. If problems are found during the inspection, they must be dealt with in a timely manner. When checking the motor temperature, first check the power and then test it with the back of the hand.

7. Except for the temporary construction electricity or temporary measures, the temporary electric wires are not allowed to be agreed, the switches and sockets are not allowed to be hanged, the instrument tools and the welding machine are safely applied, and the original electrical lines are not allowed to be changed without authorization.

Eight, the equipment needs a ground wire

The tile press must use the high number pulse input function, the high number input performance is excellent, and the AB phase has strong anti-interference ability. And use the fixed value interrupt function to ensure accuracy.

The inspection part of the tile pressing machine includes: a pulse encoder for detecting the length of the colored steel tile, a press-type upper and lower stroke switch, a cutter upper and lower stroke switch, a press-type upper and lower operation button, a cutter upper and lower stroke button, an emergency stop switch, and a hydraulic pressure. Start and stop switches and so on.

The implementation part of the tile press has a frequency converter drive motor, a hydraulic station motor, two hydraulic solenoid valves of the press type, and two hydraulic solenoid valves of the cutter.

The PLC has 14 inputs / 10 relay outputs, just to meet the input and output requirements. With the KDN text screen, you can complete parameter settings, alarm display, help information, production data display, and more.
