Pneumatic concrete vibrator

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.
