A compressed air-powered centrifugal movement of the vibrator 70-year-old, 30 years of extensive application of the cylinder (1), greater trochanter (2), a small rotor (3), the stator (4), blades (5), the left cylinder head (6), the right cylinder head (7), key (8), bolts (9) and nut (10). The present invention, light weight, easy to install, and use of safe, reliable, long life, low manufacturing cost characteristics can be obtained by adjusting the working pressure and changing the structure size of the vibration parameters of the vibrator.
Using pneumatic concrete vibrator in the large-span prestressed concrete T-beam production the following significant advantages:
(1) in the wet case, the pneumatic vibrator is no electrical job, safe and reliable.
(2) of the pneumatic vibrator life at least more than 10 years, and can work continuously for 30 000 h. To avoid the number of each precast beam field purchase vibrator (difficult) to the management and maintenance of high frequency phenomena, saving the purchase and maintenance costs of the vibrator.
(3) high-frequency vibration frequency up to 15 000 r / min or more, quickly exhaust can be reinforced concrete density. Directly improve the internal and exterior quality of bridge products; vibrator in the perfusion run time will be reduced by more than one short two; also directly reduce operating costs.
(4) The vibration frequency, amplitude, and reduced damage to the mold, increase mold life.
(5) vibrators use compressed air as power, no pollution, and its structure is simple, durable, does not produce secondary pollution caused due to repairs.
Use in prestressed concrete T-beam prefabricated pneumatic vibrator, in terms of economic investment, maintenance, environmental protection, or performance, there are considerable advantages. Especially in the rapid development of railway construction, in order to save energy, save investment and improve efficiency, the pneumatic concrete vibrator, especially in prestressed concrete T-beam and box girder precast should be widely applied.

Electric attachment, electric flat-plate vibrator
An electric plug-in vibrator
(1), the plug-in vibrator motor power, you should install leakage concrete vibrator protection device should be safe and reliable ground or zero.
(2), the operator shall be subject to electricity education, the job should wear insulated rubber boots and insulated gloves.
(3), the cable should meet the necessary length cable line shall not heap pressure of the goods or the vehicles are squeezed, is strictly prohibited electric cable dragging or hanging vibrator.
(4), before use, you should check the ministries and confirm that connections are secure, correct direction of rotation.
(5), the vibrator shall not be in the initial setting of concrete, flooring, scaffolding and hard, dry ground test vibration. When the discontinuity of the maintenance operations, disconnect the power. Operation, the vibrator hose bend radius shall be not less than 500mm
(6), and not more than two bends, the operation should the vibrator vertical deep into the concrete, shall not be forced hard plug, oblique push or let reinforced grip spare the rod, but also may not all inserted into the concrete, the insertion depth should not exceed 3/4 of the rods should not touch the steel core tube and embedded parts.
(7), vibrator hose must not be broken when the hose used for a long time so that the length of growth, should be promptly repaired or replaced.
(8), the operations stop when you need to move the vibrator should be closed to motor, and then cut off the power. Shall not use hoses to drag motor.
(9), the job is completed and should be motor, hose, vibrator clean up clean, and should be the requirements to carry out maintenance operations.Vibrator store shall not heap pressure hose should be straight away, and respond to the motor to take moisture measures.
Electric attachment, electric flat-plate vibrator
(1), attachment style, flat-plate vibrator bearings should not bear the axial force, when used, the motor shaft should be kept horizontal.
(2), a template at the same time using multiple attachment vibrator, vibrator frequency should be consistent with the relative surface of the vibrator should be staggered to install.
(3), before the job is to deal with attached vibrator to inspect and test vibration test vibration shall not be carried out on the hard, dry soil or hard objects. Mixing plant hopper vibrator, the placement of the rubber pad.
(4), when installed, the location of the vibrator baseplate mounting holes should be correct, should prevent the foot bolts the skew leaving the enclosure damaged. Foot bolts should be tightened, and the tightness of the bolts should be consistent.
(5), when used, leads to the cable may not get pulled, but not breaking. Operations, leakage protection and grounding of electrical equipment or access to zero device should be readily observed and confirmed eligible.
(6), attached to the vibrator installed in the concrete formwork, each vibration time should not exceed 1min, the concrete in the mold pan-plasma flow or horizontal like to stop vibration, not real in the state of the initial setting of concrete vibration and then .
(7), the components of the device vibrator template shall be sturdy and reliable, its size should be compatible with the vibrator rated vibration area.
(8), flat-plate vibrator operation, should the plate and concrete to keep in touch, Discovering tap concrete until the surface of the paddle, you can no longer sink slowly move forward, move the speed should be able to to ensure that concrete tap the paddle. Vibration electric concrete vibrator shall not be set aside has condensate or initial setting of concrete.
(1), the plug-in vibrator motor power, you should install leakage concrete vibrator protection device should be safe and reliable ground or zero.
(2), the operator shall be subject to electricity education, the job should wear insulated rubber boots and insulated gloves.
(3), the cable should meet the necessary length cable line shall not heap pressure of the goods or the vehicles are squeezed, is strictly prohibited electric cable dragging or hanging vibrator.
