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.
