Ordinary concrete mixer is generally powered by chassis engine, and then the rotating power of diesel engine is transformed into the hydraulic pressure of hydraulic pump (also divided into gear pump or piston pump) by hydraulic pump, the hydraulic oil is transmitted to the hydraulic motor by hydraulic pipe, the pressure is transformed into power, and the mixing tank is driven to rotate by reducer. Specifically, the circulation path of the hydraulic oil flows directly to the hydraulic motor after coming out of the gear pump or plunger pump. The gear pump also needs to change the path of the hydraulic oil path through the directional valve to change the rotation direction of the mixing tank. The hydraulic oil needs to be cooled after coming out of the hydraulic motor, so the hydraulic oil flows to the radiator, After the radiator comes out, it flows back to the gear pump or plunger pump.

除了直接采用车辆底盘发动机驱动的搅拌罐外,单独的混凝土搅拌罐上装又分为由电机驱动的混凝土搅拌罐和柴油机驱动的混凝土搅拌罐,这两种可单独固定在地面或平板车上。
In addition to the mixing tank directly driven by vehicle chassis engine, the separate concrete mixing tank can be divided into motor-driven concrete mixing tank and diesel engine driven concrete mixing tank, which can be fixed on the ground or flat car separately.
而这两种需要注意的是，使用的时候要注意看液压油散热器和风扇是否正常工作。柴油机驱动的搅拌罐在厂家出厂时候是不带电瓶的，但是液压油散热器风扇是需要供电才能工作的。在混凝土搅拌车上，都带有发电机电瓶的，厂家会直接接好，柴油机式的单罐上装就需要配备电源来给柴油机打火启动，并且给散热器风扇供电。如果是电机式的单罐上装，就不需要单独再安装散热器了。
And these two need to pay attention to is, when using to pay attention to see whether the hydraulic oil radiator and fan work normally. The mixing tank driven by diesel engine does not have battery when it is delivered from the factory, but the hydraulic oil radiator fan needs power supply to work. In the concrete mixer truck, there is a generator battery. The manufacturer will connect it directly. The single tank of diesel engine type needs to be equipped with power supply to start the diesel engine and supply power to the radiator fan. If it is a motor type single tank mounted, there is no need to install a separate radiator.
在日常的保养上，一定要及时更换液压油，及时的更换液压油使液压油保持良好清洁度，可以减少细小杂物对换向阀的损害。
In the daily maintenance, we must timely replace the hydraulic oil, timely replace the hydraulic oil to keep the hydraulic oil clean, can reduce the damage of small debris to the valve.
在从正转改变反转或者从反转改变为正转的时候，先降低小型混凝土搅拌车搅拌罐的转速，不要在保持高转速的情况下突然改变转向。定期的检查小型混凝土搅拌车的换向阀，看有没有进、排气孔被油泥或其他杂物堵塞，封闭不严等问题，及时检查换向阀的问题，并去还可以有效提高工作效率，以免它在关键的时候掉链子。
When changing from forward rotation to reverse rotation or from reverse rotation to forward rotation, first reduce the rotation speed of the mixing tank of the small concrete mixer, and do not change the direction suddenly while maintaining a high rotation speed. Regularly check the reversing valve of the small concrete mixer to see if the inlet and exhaust holes are blocked by oil sludge or other debris, and the sealing is not strict. Timely check and solve the problems of the reversing valve, which can also effectively improve the work efficiency, so as not to drop the chain at the critical time.
