現在的專(zhuān)用車(chē)上很多都安裝有動(dòng)力轉向的，動(dòng)力轉向可以讓駕駛員開(kāi)車(chē)更輕松，混凝土攪拌車(chē)上也有動(dòng)力轉向，動(dòng)力轉向作為攪拌車(chē)的零部件之一，也是避免不了會(huì )出現這樣那樣的故障的，混凝土攪拌一體車(chē)的動(dòng)力轉向容易出現哪些故障呢？一起來(lái)看一下吧。

Nowadays, many special vehicles are equipped with power steering. Power steering can make driving easier for drivers. Concrete mixer also has power steering. As one of the parts of mixer, power steering can't avoid such and such failures. What are the common failures of power steering of concrete mixer? Let's have a look.

1. 混凝土攪拌車(chē)動(dòng)力轉向在使用過(guò)程中會(huì )出現轉向里不足或者不均勻。2. 混凝土攪拌車(chē)油泵驅動(dòng)皮帶松緊度不合適。3. 油泵缸缺油，或有氣泡，或有雜質(zhì)阻塞。4. 混凝土攪拌車(chē)油泵保險閥座松脫，旁通閥卡住，泵油不足。5. 定子和葉片的磨損過(guò)度，槽內有油污，葉片卡滯引起泵油壓力不足。6. 齒輪嚙合過(guò)松，使攪拌車(chē)轉向盤(pán)轉動(dòng)時(shí)沉重。7. 密封環(huán)因磨損或折斷而漏油。8. 轉向螺桿的軸承螺母松動(dòng)。9. 油面過(guò)高，過(guò)濾網(wǎng)堵塞，集油管彎曲，或者襯套損壞，油從油泵通氣閥處甩出，液壓轉向助力器有異響：攪拌車(chē)的油泵有聲響，這是因為油液不足，皮帶過(guò)松，系統中有空氣，濾網(wǎng)堵塞，集油管彎曲，集流管下墊損壞和安裝不當等引起的；攪拌車(chē)的轉向助力器有沖擊聲響，主要是齒輪嚙合過(guò)松，間隙過(guò)大引起的。
           

1. The power steering of concrete mixer truck will be insufficient or uneven in use. 2. The tightness of oil pump drive belt of concrete mixer truck is not suitable. 3. The oil pump cylinder is short of oil, or there are bubbles or impurities blocking. 4. The safety valve seat of concrete mixer pump is loose, the bypass valve is stuck, and the pump oil is insufficient. 5. Excessive wear of stator and blade, oil contamination in groove, blade sticking, resulting in insufficient pump oil pressure. 6. The meshing of gears is too loose, which makes the steering wheel of mixer heavy when it rotates. 7. The sealing ring leaks oil due to wear or fracture. 8. The bearing nut of the steering screw is loose. Nine The oil level is too high, the filter screen is blocked, the oil collecting pipe is bent, or the bushing is damaged, the oil is thrown out from the oil pump vent valve, and the hydraulic steering booster has abnormal sound: the oil pump of the mixer has sound, which is caused by insufficient oil, too loose belt, air in the system, blocked filter screen, bent oil collecting pipe, damage to the bottom pad of the collecting pipe, and improper installation; the steering booster of the mixer has impact The impact noise is mainly caused by too loose gear mesh and too large clearance.

混凝土攪拌一體車(chē)在現代的社會(huì )建設中是不可或缺的一種專(zhuān)用車(chē)，使用范圍廣泛，建筑工程，一些大型項目的建設等都離不開(kāi)攪拌車(chē)，攪拌車(chē)的使用大大提高了混凝土的質(zhì)量，進(jìn)而也提高了建筑物的質(zhì)量?；炷翑嚢柢?chē)運輸車(chē)實(shí)惠，而且現在都是輕量化的設計，額定載質(zhì)量大，購買(mǎi)是很劃算的。

Concrete mixer truck is an indispensable special vehicle in modern social construction. It is widely used. Construction engineering and construction of some large projects are inseparable from mixer truck. The use of mixer truck greatly improves the quality of concrete, and further improves the quality of buildings. Concrete mixer truck is affordable, and now it is lightweight design, rated load mass is large, it is very cost-effective to buy.
