Hydraulic drive block making machine better than mechanical drive machine

Some say hydraulic transmission block making machine than mechanical drive machine is good, not only when the molding is also pressurized vibration. This argument is mainly due to the hydraulic drive machine, the molding pressure and vibration block forming the vibration system is not yet understood. Take the United States produced Bessel type BH3-1 machine, the pressure in the cylinder head vibration molding hydraulic valve has been reduced by approximately 0.5Mpa,Autoclaved Aerated Concrete block plant cylinder head mold box with a pressure head with synchronized vibration compacting concrete in decline, this time in a low-pressure cylinder head floating state, can not exert a lot of pressure. In addition, if the vibration is applied great pressure molding, equal to a substantial increase in vibration loads, will be greatly attenuated amplitude vibration system vibration up. General machine vibration system design and calculation of vibration parameters when selecting vibration motor power, vibration loads considered include block, mold box and head quality, vibration molding machine for Taiwan should also include quality vibration table, but generally applied without regard to the additional pressure. So whether hydraulic, or mechanical drive machine, block making mainly by vibrations when the material dense. Thixotropic phenomenon concrete mix according to vibration effects when,Automatic controlling system in a relatively small pressure may be obtained within a short period of time dense, so the need to exert a certain pressure on the concrete when the ram block vibration molding. Our standard block making machine head on the block surface pressure value should be greater than 0.02Mpa, the value of foreign pressure on dry concrete mixes about 0.015Mpa, too much pressure will prevent the concrete mixture granule vibration, impact block density effect. Value at the pressing, the pressure is generally the weight of the ram block molding machine produced to meet the requirements, particularly in the ram vibrator is set, the vibration compacting effect than static effect.
