The ZN planetary
internal concrete vibrator with flexible shaft driven by electric motor is an
important instrument for concrete construction. It is widely used in
construction industry to consolidate and compact various plastic, semi-plastic
or nearly dry concrete. Our company is a professional manufacturer of concrete vibrator inChina. Our products have gained the
CE certification.
Features of Electric Concrete manual operation Held Pokers
1. The concrete vibrating poker mainly
consists of two components: a driving electric motor and a vibrator head which includes
a vibrating body and a set of flexible pipe and shaft. The concrete vibrator
has the features of simple structure, easy operating and less maintenance.
2. Notes: left-manual
operation threads are supplied at the ends of the casing .The connection thread
between flexible shafts and rolling body is right handed.
3. There are three
kinds of coupling method between flexible shaft and rotating shaft of motor, which
can be separately supplied as per buyer’s demands.
4. The driving electric
motor is a three phase or single phase asynchronous motor with anti reverse
elements which can avoid damage to flexible shaft.
5. When the motor is accidentally
rotating in reverse direction, the red arrow mark on the coupler of the motor indicates
its right rotating direction.
Precautions
1. Check the insulation
resistance of the motor before you put concrete
vibrating poker into use. The value must be not below 1Ω.
The Green-yellow or light blue wire in the power supply cable is the ground
wire. A three phase or single phase residual current protective switch should
be included in the power supply circuit.
2. Insert the pipe
connector and the shaft into the motor coupler, and then tighten them with the
spanner.
3. Exchange the three
phase wires once you find the motor is rotating in reverse direction. Otherwise,
the flexible shaft doesn’t rotate when the concrete vibrator is operating.
4. Shake the vibrating needle
against the ground to begin vibrating until you hear a sound as "WU WU” when
the motor is normally operating then you can put the vibrating needle into the concrete.
5. Let the needles sink
into the concrete without exerting external force. You cannot weld steel tubes
to the needle and let it vibrate while the needle is still in the air, which
will cause severe damage. The bending radius of the flexible pipe should of at
least 500mm, otherwise the durability will decrease.
Care and Maintenance
1. Clean thoroughly the
whole machine after being used and keep the electric motor.
2. Perform maintenance
after having used the machine for a certain period of time. Clean and add some
high quality grease to the bearing in the vibrating needle to extend the
vibrator head’s service life. When reassembling, keep the space from the
bearing to the cone inside the vibration body free of dust, oil and water.
3. The machine will
likely encounter some water or and oil during the operation. To ensure the
correct functioning of the flexible shaft, you should disassemble the vibrating
needle to clean its inside with petrol thoroughly.
4. After a certain
period of usage, the flexible pipe may be worn out or stretched, resulting difficulties
connecting the flexible shaft plug with rotating shaft. In such case, you
should disassemble the conical sleeve, cut off the over length pipe and
reassemble them. Then, the vibrator head can be put into use again.
5. If the fuse is burnt
when the motor is operating, check for if it was overload or a short circuit,
substitute the fuse and perform the necessary repairs.
