Nowadays, many special-purpose vehicles are equipped with power steering. Power steering can make driving easier for the driver, and power steering is also available on the mixer. As one of the parts of the mixer, power steering can not avoid one kind of fault. What faults are prone to occur in the power steering of the mixer? Let's have a look.

1. 攪拌車動力轉向在使用過程中會出現轉向里不足或者不均勻。

1. the power steering of the mixer truck may be insufficient or uneven during use.

2. 混凝土攪拌車油泵驅動皮帶松緊度不合適。

2. the tightness of the oil pump drive belt of the concrete mixer truck is inappropriate.

3. 油泵缸缺油，或有氣泡，或有雜質阻塞。

3. the oil pump cylinder is short of oil, or has bubbles, or is blocked by impurities.

4. 攪拌車油泵保險閥座松脫，旁通閥卡住，泵油不足。

4. the safety valve seat of the oil pump of the mixer truck is loose, the bypass valve is stuck, and the pump oil is insufficient.

5. 定子和葉片的磨損過度，槽內有油污，葉片卡滯引起泵油壓力不足。

5. excessive wear of stator and blade, oil stain in the groove, and insufficient pump oil pressure caused by stuck blade.

6. 齒輪嚙合過松，使攪拌車轉向盤轉動時沉重。

6. the gear engagement is too loose, which makes the steering wheel of the mixer heavy when rotating.

7. 密封環因磨損或折斷而漏油。

7. the sealing ring leaks oil due to wear or fracture.

8. 轉向螺桿的軸承螺母松動。

8. the bearing nut of the steering screw is loose.

9. 油面過高，過濾網堵塞，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：攪拌車的油泵有聲響，這是因為油液不足，皮帶過松，系統中有空氣，濾網堵塞，集油管彎曲，集流管下墊損壞和安裝不當等引起的；攪拌車的轉向助力器有沖擊聲響，主要是齒輪嚙合過松，間隙過大引起的。

9. 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 vent valve of the oil pump, and the hydraulic steering booster has abnormal noise: the oil pump of the mixer truck has a sound, which is caused by insufficient oil, 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 truck has impact sound, which is mainly caused by too loose gear engagement and too large clearance.

攪拌車在現代的社會建設中是不可或缺的一種專用車，使用范圍廣泛，建筑工程，一些大型項目的建設等都離不開攪拌車，攪拌車的使用大大提高了混凝土的質量，進而也提高了建筑物的質量。混凝土攪拌車運輸車價格實惠，而且現在都是輕量化的設計，額定載質量大，購買是很劃算的。

Mixer truck is an indispensable special vehicle in modern social construction. It is widely used. Construction projects and the construction of some large projects are inseparable from mixer truck. The use of mixer truck has greatly improved the quality of concrete and buildings. Concrete mixer trucks are affordable, and now they are all light-weight design, with large rated load, so it is very cost-effective to buy.
