1.Electric insertion type vibrator

(1) plug-in vibrator motor power supply, should be installed on the leakage protection device, grounding or zeroing should be safe and reliable.

(2) The operator should be educated in electricity, and should wear insulated rubber shoes and insulated gloves when operating.

(3) The cable line should meet the length required for operation, the cable line should not be stacked on items or let the vehicle squeeze, and it is strictly prohibited to drag or hang the vibrator with the cable line.

(4) before use, should check each ministry and confirm that the connection is solid and the rotation direction is correct.

(5) The vibrator shall not be used for trial vibration on the concrete, floor, scaffolding and dry hard ground. When the maintenance operation is interrupted, the power should be disconnected.

(6) operation, the bending radius of the vibrator hose shall not be less than 500mm, and shall not be more than two bends, the operation of the vibrator should be vertical low into the concrete, not hard inserted, diagonally pushed or let the rebar pinch the rod head, nor shall all inserted into the concrete, the insertion depth should not exceed the rod length of 3 ∕4, should not touch the rebar, core pipe and pre-buried parts.

(7) vibrating rod hose shall not appear broken, when the hose used too long to make the length of growth, should be promptly repaired or replaced.

(8) operation stop need to move the vibrator, should first shut down the motor, and then cut off the power. Do not drag the motor with the hose.

(9) When the operation is finished, the motor, hose and vibrator should be cleaned up, and maintenance work should be carried out according to the requirements. When storing the vibrator, the hose should not be stacked and pressed, but should be put straight and the motor should be protected from moisture.

2. Electric attached type and electric flat plate type vibrator

(1) Attachment type and plate type vibrator bearings should not bear axial force, and the motor shaft should be kept horizontal when in use.

(2) When using more than one attached vibrator on a template at the same time, the frequency of each vibrator should be consistent, and the vibrators on opposite sides should be installed staggered.

(3) Before operation, the attached vibrator should be inspected and test vibrated, and the test vibration should not be carried out on dry hard soil or hard objects. The vibrator installed on the silo of the mixing plant should be placed on the rubber pad.

(4) When installing the vibrator, the location of the bottom plate mounting holes should be correct, and the foot bolts should be prevented from being twisted and slanted to cause damage to the housing. The foot bolt should be tightened, and the tightening degree of each bolt should be consistent.

(5) When using, the lead cable should not be pulled too tightly, and should not be broken. When working, should always observe the electrical equipment leakage protector and grounding or zeroing device and confirm qualified.

(6) attached vibrator installed in the concrete formwork, each vibration time should not exceed 1min, when the concrete in the mold flooding flow or into the horizontal can stop vibration, not in the concrete in the first state of solid vibration again.

(7) the installation of vibrators should be strong and secure components of the formwork, the area should be compatible with the vibrator rated vibration area.

(8) plate type vibrator operation, should make the plate and concrete to maintain contact, so that the vibration wave effectively vibrate the concrete, to be the surface of the paddle, no longer sink, you can slowly move forward, the speed of movement should be able to ensure that the concrete vibration paddle. In the vibration of the vibrator, shall not be resting on the concrete has been set or first set.
