Finding the right vibrator for the nature and condition of the concrete construction

Finding the right vibrator for the nature and condition of the concrete construction 1930s With the principle of high frequency vibration planetary roller cone; the late 1950s, planetary roller cone of high-frequency electric vibrators gained popularity. Vibrator means using vibration excitation and vibration transmitted to the device by compacting concrete to make prefabricated template. When concrete vibrator, the inner concrete internal friction and adhesion between particles decreases sharply, concrete was heavy liquid state, aggregate reciprocal slide and rearrange the space between is filled with mortar aggregate, bubbles extrusion, hot sell twin-shaft concrete mixer so as to achieve the effect of compacting. First it appeared vibrator pneumatic piston type, followed the production of electric eccentric. In the infusion process, it is necessary to ensure the concrete dense, while to prevent excessive vibration. Vibration time and vibration forces to be controlled just right. Perfusion initial stage, the pouring of concrete vibrators gas supply valve parts only open to 1/3 the size of the vibration at this time is focused on helping the concrete flow, but also play the role of a tap. When the thickness of the concrete at the bottom flange of the beam is required when the vibrator air valve fully open. Perfusion end, the deck and walls vibrating rod position required secondary vibration. Applying pneumatic vibrators, vibration force size and the length of time vibration directly affects the appearance quality of the beam. The need to explore the use of the most appropriate vibration process at any time if necessary adjustments, including adjustments vibration time and vibration force size.   Concrete vibrator according to work is divided into plug-in (internal), attached to the formula (external) and tablet (surface); press power into electric, pneumatic, pneumatic, combustion and hydraulic; press vibration frequency divided MF, HF and complex frequency; by excitation principle into eccentric, planetary, reciprocating and electromagnetic type and so on. Basic technical parameters of the vibrator is: vibration frequency, amplitude, centrifugal force and structural dimensions. In recent years, in order to meet concrete materials and construction methods changing needs of the new structure of the vibrator continue to come out. The selection of vibrators, must address the nature and construction of south africa brand stationary concrete batch mixer plant for sale concrete conditions, a reasonable choice of vibration parameters and structural dimensions of the vibrator, will achieve the desired effect of vibration. Application mode and the difference between the vibrator Vibrator use the centrifugal effect of new high-speed rotation of the vibration motor, high frequency vibration of the machine, thereby eliminating the relative stability of the material inside the warehouse and silo wall friction between the materials, so that the material discharged from the hatch successfully. Also known as anti-blocking devices vibration shaker or silo anti-clogging device, generally applicable to the hopper, silos or pipe material handling in circulation, and the true emergence of silos or pipe from Gong, or the material damp stained walls, or relatively poor liquidity and sand particles clogging the discharge port has a good clear role. True to stick wall material treatment of the phenomenon is in fact a very good explanation, Anyang vibrator after high-frequency vibration, the transmitting power to the silo wall warehouse, to produce resonance in good quality concrete mixer machine the high frequency vibration effects, materials It will gradually separated from the silo wall adhesive layer, without the need to beat the original force. Now on the market circulation product actually Anyang vibrator In principle there are two. One is electromagnetic vibration Anyang vibrator The second is it used motor vibration Anyang vibrator And the difference between these two points and use environment is, the applicable market Anyang vibrator motor vibration bigger. After all motor vibration from the environment, in the maintenance is relatively simple, and the market in general mechanical and electrical maintenance technician can. Anyang electromagnetic vibrator particular, fear tide, using a great influence on the electromagnetic force, once in a humid environment, the ability to directly reduce vibration. Motor anti-blocking devices in the model applied in the vibration motor is relatively simple, but the name issue. For example, the vibration motor on the market favorable js500 concrete mixer price now frequently used, YZS vibrating motor, YZO vibration motor or vibration motor TZD So, Anyang vibrator model is more flexible in applying the motor, which has nothing to do with the overall vibration capability.
