自動混凝土攪拌機是一種長距離輸送商品混凝土的專用車輛，由于混凝土對攪拌筒和溜槽有一定的腐蝕作用，同時為了防止殘余混凝土在攪拌筒內凝固，攪拌車在卸料完成后應當對攪拌筒和溜槽進行清洗。下面來講講自動混凝土攪拌機的氣路系統原理。

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.

自動混凝土攪拌機氣路系統從底盤氣瓶取氣，經過減壓閥調壓，往水箱內充氣，使水箱內壓力為0.4MPa，為攪拌車水箱放水沖洗提供壓力；當水箱加水時，通過調節操作手柄將氣壓排出，便于加水。水箱上閥的工作壓力調節為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.

目前自動混凝土攪拌機的氣路系統大都采用氣控箱集成控制的方式，單向閥、減壓閥、壓力表、調節手柄等氣路元件集成在氣控箱內。市場上不同廠家的自動混凝土攪拌機采用的氣控箱基本相同。

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.

氣控箱選用的壓力表為1.6級防震壓力表，能夠適應攪拌車顛簸的運行工況。單向閥開啟壓力設定為0.2～0.3MPa，減壓閥設定為0.4MPa。氣控箱總成裝配完成后要進密性試驗，要求氣路中采用0.4MPa的氣壓試壓，保壓2分鐘無泄漏。

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.

自動混凝土攪拌機的供水方案大都為氣壓式，即從攪拌車底盤氣瓶取氣，通過氣壓將閉式水箱內的水擠壓工作水龍頭，確保水壓穩定，沖洗干凈。更多相關內容就來我們網站http://www.gdfcx.net咨詢吧！

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.
