Types of concrete vibrators more

Types of concrete vibrators more. Commonly used classification methods are the following: 1) the method according to the transmission of vibration points, internal vibrators, external vibrators and surface vibrators three. Internal vibrators known as plug-in vibrators. Work horn 1 is inserted inside the concrete, the vibration wave directly to the concrete. Such vibrators are used for vibration pressure concrete layer thickness larger, concrete mold vibrator such as piers, abutments and group pile foundation. Its advantage is light weight, easy to move, use very extensive. Also known as external vibrators vibrators attached, is an electric motor having a vibration effect, the machine is installed on the bottom floor specially when working on the template attached to the floor, the shock wave generated by the vibrator plate and Template indirectly pass concrete. Such vibrators are used for shell member, hollow plate girder, arch rib, T-beams and other places construction. According to the needs of the construction, in addition to external vibrators attached type, there is a vibration table, which is used vibrated concrete preform. Installed in the template preform is placed on the table and vibrators connected vibration wave vibrators produced precast concrete products pass through the table with the template. Surface vibrators is it directly on the concrete surface, vibration generated by vibrating wave vibrators with fixed base 1 pass concrete. Since the shock wave is passing from the concrete surface, so that the surface of vibrators. Hold the work by two vibrators handle 4, according to the work needs to be drag. It is suitable for construction of small thickness of concrete pavement and bridge and other projects. 2) Press vibrators source of power, there are electric, and pneumatic internal combustion type three, the most widely used in electric. 3) Press vibrators vibration frequency, Electric Concrete Vibrator for Sale price low-frequency type, medium type and high frequency three. Low-frequency type of vibration frequency of 25 ~ 50HZ (1500 ~ 3000 times / min); IF formula is 83 ~ 133HZ (5000 ~ 8000 times / min); high frequency formula 167HZ (10000 times / min) or more. Principle Press vibrators generate vibrations points, there are two eccentric and planetary. Vibration structure and working principle are: eccentric. It is the use of the shaft with an eccentric mass vibrator central mounting of the centrifugal force at high speed rotation of the rod through the bearing vibration transmitted to the housing, so that the rods to produce circumferential vibration. Excitation planetary principle. It is the use of vibrating rods vacant end of the shaft when it rotates, the conical part of its sagging housing along the rod end of the conical surface roll, thereby forming a planetary motion rolling element to drive the rod vibration generated circumference.

Mixing concrete mixing machine with good concrete pouring member, you must be excluded where bubbles were tamping, compacting the concrete binding, and other concrete Honeycomb eliminate the phenomenon, in order to improve its strength, ensure the quality of the concrete member. Concrete vibrators is mechanized tamping concrete machinery.

Such vibrators are used for shell member, hollow plate girder, arch rib, T-beams and other places construction. According to the needs of the high frequency concrete vibrator construction, in addition to external vibrators attached type, there is a vibration table, which is used vibrated concrete preform.
