自动混凝土搅拌机是一种长距离输送商品混凝土的专用车辆,由于混凝土对搅拌筒和溜槽有一定的腐蚀作用,同时为了防止残余混凝土在搅拌筒内凝固,搅拌车在卸料完成后应当对搅拌筒和溜槽进行清洗。下面来讲讲自动混凝土搅拌机的气路系统原理。
The automatic concrete mixer is a special vehicle for transporting commercial concrete for a long distance. Since the concrete has a certain corrosion effect on the mixing drum and chute, and in order to prevent the residual concrete from solidifying in the mixing drum, the mixing truck should clean the mixing drum and chute after unloading. Now let's talk about the principle of the air passage system of the automatic concrete mixer.
自动混凝土搅拌机气路系统从底盘气瓶取气,经过减压阀调压,往水箱内充气,使水箱内压力为0.4MPa,为搅拌车水箱放水冲洗提供压力;当水箱加水时,通过调节操作手柄将气压排出,便于加水。水箱上阀的工作压力调节为0.5MPa。
The air circuit system of the automatic concrete mixer takes air from the chassis cylinder, regulates the pressure through the pressure reducing valve, and inflates the water tank to make the pressure in the water tank 0.4MPa, providing pressure for the water tank flushing of the mixer; When the water tank is filled with water, the air pressure is discharged by adjusting the operating handle to facilitate water filling. The working pressure of the safety valve on the water tank is adjusted to 0.5MPa.

目前自动混凝土搅拌机的气路系统大都采用气控箱集成控制的方式,单向阀、减压阀、压力表、调节手柄等气路元件集成在气控箱内。市场上不同厂家的自动混凝土搅拌机采用的气控箱基本相同。
At present, the air circuit system of automatic concrete mixer mostly adopts the integrated control mode of air control box. The one-way valve, pressure reducing valve, pressure gauge, regulating handle and other air circuit elements are integrated in the air control box. The air control box used by automatic concrete mixers from different manufacturers in the market is basically the same.

气控箱选用的压力表为1.6级防震压力表,能够适应搅拌车颠簸的运行工况。单向阀开启压力设定为0.2~0.3MPa,减压阀设定为0.4MPa。气控箱总成装配完成后要进密性试验,要求气路中采用0.4MPa的气压试压,保压2分钟无泄漏。
The pressure gauge selected for the pneumatic control box is a 1.6 level shockproof pressure gauge, which can adapt to the bumpy operating conditions of the mixer truck. The opening pressure of one-way valve is set as 0.2~0.3MPa, and the pressure reducing valve is set as 0.4MPa. After the assembly of the air control box assembly is completed, the air tightness test shall be carried out. It is required that 0.4MPa air pressure shall be used in the air circuit for pressure test, and there shall be no leakage after maintaining the pressure for 2 minutes.
自动混凝土搅拌机的供水方案大都为气压式,即从搅拌车底盘气瓶取气,通过气压将闭式水箱内的水挤压工作水龙头,确保水压稳定,冲洗干净。更多相关内容就来我们网站http://www.zkhntjbc.com咨询吧!
Most of the water supply schemes for automatic concrete mixers are pneumatic, that is, air is taken from the cylinder on the chassis of the mixer truck, and the water in the closed water tank is squeezed to the working tap through air pressure to ensure stable water pressure and clean flushing.
