Maintenance of small concrete automatic loading mixer

1、液壓驅(qū)動(dòng)系統(tǒng)：液壓系統(tǒng)是攪拌車的核心系統(tǒng)。為保證攪拌車能正常工作，攪拌罐能運(yùn)轉(zhuǎn)正常，在每次車輛發(fā)動(dòng)前檢查油路散熱器和減速機(jī)的液壓油位，保證油位指示在視窗范圍內(nèi)。同時(shí)要保證其清潔性，以免塵粒和水分等污染系統(tǒng)液壓油，造成系統(tǒng)不能正常工作或損壞。

1. Hydraulic drive system: hydraulic system is the core system of mixer truck. In order to ensure that the mixer truck can work normally and the mixing tank can operate normally, check the hydraulic oil level of the oil circuit radiator and reducer before each vehicle start to ensure that the oil level indication is within the window range. At the same time, its cleanliness shall be ensured to prevent dust particles and moisture from polluting the hydraulic oil of the system, resulting in the failure or damage of the system.

2、供水系統(tǒng)：氣壓供水系統(tǒng)加水量一般在水箱的四分之三處為宜；車輛在行駛時(shí)水路系統(tǒng)中各個(gè)閥門均應(yīng)處于關(guān)閉狀態(tài)，以免影響車輛的制動(dòng)性能，或燒結(jié)摩擦片，從而影響車輛的制動(dòng)性能。禁止隨意焊接和改動(dòng)水箱，避免重物撞擊；經(jīng)常檢查閥體是否堵塞或是否有工作異常；在有結(jié)冰可能的環(huán)境中使用時(shí)，供水系統(tǒng)排空存水，防止管路凍裂；經(jīng)常檢查系統(tǒng)的密封性，拆卸修理后，關(guān)鍵部位要涂螺紋密封膠。

2. Water supply system: the water volume of pneumatic water supply system is generally three-quarters of the water tank; When the vehicle is running, all valves in the waterway system shall be closed to avoid affecting the braking performance of the vehicle or sintering the friction plate, thus affecting the braking performance of the vehicle. It is forbidden to weld or change the water tank at will to avoid the impact of heavy objects; Frequently check whether the valve body is blocked or abnormal; When it is used in an environment with the possibility of icing, the water supply system shall empty the stored water to prevent the pipeline from freezing and cracking; Regularly check the tightness of the system. After disassembly and repair, the key parts shall be coated with thread sealant.

3、攪拌筒：初次使用50h要及時(shí)檢查罐體及其他部位螺栓是否有松動(dòng)，每天行車前要檢查托輪與滾道的潤(rùn)滑，每個(gè)月打開一次托輪護(hù)罩，清理內(nèi)部的油污并添加潤(rùn)滑油脂。

3. Mixing drum: after 50h of initial use, timely check whether the bolts of the tank and other parts are loose. Check the lubrication of the supporting wheel and raceway every day before driving. Open the supporting wheel shield once a month to clean the internal oil stain and add lubricating grease.

Maintenance of small concrete mixer

小型混凝土攪拌車在某些行業(yè)的運(yùn)輸方面可謂是不可或缺的，不過近期很多用戶向我們咨詢?yōu)槭裁此墓ぷ餍试絹?lái)越低，那么出現(xiàn)這一狀況的原因可能是因?yàn)闆]有及時(shí)保養(yǎng)維修，再者或許是因?yàn)闆]有正確的保養(yǎng)，相信后者所占的比例應(yīng)該是很大的，那么具體它有哪些保養(yǎng)禁忌呢？

Small concrete mixers are indispensable in the transportation of some industries, but recently many users have asked us why their work efficiency is getting lower and lower. The reason for this may be that they have not been maintained in time, or that they have not been properly maintained. I believe the latter should account for a large proportion, So what are the specific maintenance taboos?

1、忌機(jī)油只加不換；

1. Avoid only adding engine oil without changing it;

2、混凝土商砼車忌缸套和活塞新品不經(jīng)選配即安裝；

2. It is forbidden to install new cylinder liners and pistons of concrete commercial vehicles without selection;

3、水泥運(yùn)輸車忌不檢查柱塞行程余量。

3. Do not check the plunger stroke allowance of cement truck.
