普通的混凝土攪拌車一般都是由底盤發(fā)動(dòng)機(jī)提供動(dòng)力，然后通過(guò)液壓泵把柴油機(jī)的旋轉(zhuǎn)動(dòng)力轉(zhuǎn)化為液壓泵（又分齒輪泵或活塞泵）的液壓壓力，把液壓油用液壓管輸送到液壓馬達(dá)，將壓力轉(zhuǎn)化為動(dòng)力，通過(guò)減速機(jī)驅(qū)動(dòng)攪拌罐旋轉(zhuǎn)。具體的就是液壓油的循環(huán)路徑自齒輪泵或柱塞泵出來(lái)之后，直接流向液壓馬達(dá)齒輪泵還需要通過(guò)換向閥來(lái)改變液壓油路的路徑，以此來(lái)改變攪拌罐的旋轉(zhuǎn)方向，液壓油從液壓馬達(dá)出來(lái)之后需要冷卻，因此液壓油流向散熱器，出來(lái)散熱器之后再重新流回齒輪泵或柱塞泵。混凝土攪拌車
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.

除了直接采用車輛底盤發(fā)動(dòng)機(jī)驅(qū)動(dòng)的攪拌罐外,單獨(dú)的混凝土攪拌罐上裝又分為由電機(jī)驅(qū)動(dòng)的混凝土攪拌罐和柴油機(jī)驅(qū)動(dòng)的混凝土攪拌罐,這兩種可單獨(dú)固定在地面或平板車上。
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.
而這兩種需要注意的是，使用的時(shí)候要注意看液壓油散熱器和風(fēng)扇是否正常工作。柴油機(jī)驅(qū)動(dòng)的攪拌罐在廠家出廠時(shí)候是不帶電瓶的，但是液壓油散熱器風(fēng)扇是需要供電才能工作的。在混凝土攪拌車上，都帶有發(fā)電機(jī)電瓶的，廠家會(huì)直接接好，柴油機(jī)式的單罐上裝就需要配備電源來(lái)給柴油機(jī)打火啟動(dòng)，并且給散熱器風(fēng)扇供電。如果是電機(jī)式的單罐上裝，就不需要單獨(dú)再安裝散熱器了。

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.
在日常的保養(yǎng)上，一定要及時(shí)更換液壓油，及時(shí)的更換液壓油使液壓油保持良好清潔度，可以減少細(xì)小雜物對(duì)換向閥的損害。
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.
在從正轉(zhuǎn)改變反轉(zhuǎn)或者從反轉(zhuǎn)改變?yōu)檎D(zhuǎn)的時(shí)候，先降低小型混凝土攪拌車攪拌罐的轉(zhuǎn)速，不要在保持高轉(zhuǎn)速的情況下突然改變轉(zhuǎn)向。定期的檢查小型混凝土攪拌車的換向閥，看有沒有進(jìn)、排氣孔被油泥或其他雜物堵塞，封閉不嚴(yán)等問題，及時(shí)檢查換向閥的問題，并去還可以有效提高工作效率，以免它在關(guān)鍵的時(shí)候掉鏈子。
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.
