In the morning, when the small concrete mixer is cold started, pay attention to check the outlet of the exhaust pipe. If the exhaust pipe emits blue smoke when it is just started, it will clarify that the concrete mixer burns engine oil. This method is completed by two people, one starts the concrete mixer, and the other is responsible for the investigation.

由于冒蓝烟的时间很短，并且只有在搅拌机长期放置今后才会呈现。大油门时冒蓝烟当混凝土搅拌机急加速或原地轰油门时呈现冒蓝烟现象，而怠速时根本没有，这种情况阐明混凝土搅拌机烧机油，并且现已比较严重了，应赶快修理。

Because the time of blue smoke is very short, and only after long-term storage in the mixer, it will appear in the future. Blue smoke is emitted when the accelerator is high. Blue smoke is emitted when the concrete mixer accelerates rapidly or blows the accelerator in place, but not at idle speed. This situation illustrates that the concrete mixer burns engine oil, and it is serious now. It should be repaired as soon as possible.

机油注进口冒蓝烟假如混凝土搅拌机除了排气口，机油注进口也开始冒蓝烟，阐明此症状现已到达中晚期了，烧机油的情况非常严重，需求赶快就医，以免形成更大的损伤。

Blue smoke from the engine oil inlet if the concrete mixer starts to emit blue smoke from the engine oil inlet in addition to the exhaust port, it is clarified that this symptom has now reached the middle and late stage, and the situation of burning engine oil is very serious. It is necessary to see a doctor as soon as possible to avoid greater damage.

搅拌机汽缸的密封性差是形成烧机油的首要原因。首要是活塞与缸壁间的合作间隙过大、活塞环的安装不当或密封性变差，缸壁上的机油进入燃烧室，引起烧机油现象。

The poor sealing of mixer cylinder is the primary reason for oil burning. The main reason is that the clearance between piston and cylinder wall is too large, the piston ring is not properly installed or the sealing is poor, and the oil on cylinder wall enters the combustion chamber, causing oil burning.

尽可能挑选品质好的机油，老旧混凝土搅拌机可适当选用粘度稍大的机油来添加活塞、缸壁间的密封性，长期运用矿物质机油，改用全组成机油后也容易呈现密封不严的情况。勤检查小型混凝土搅拌机机油标尺，定时替换混凝土搅拌机机油和机油滤清器，替换正品机油滤清器备件，挑选原厂的机油等，都可有用避免混凝土搅拌机烧机油现象。

Choose good quality engine oil as far as possible, old concrete mixer can appropriately choose a slightly higher viscosity engine oil to add the sealing between piston and cylinder wall, long-term use of mineral engine oil, after using full composition engine oil, it is easy to present the situation of lax sealing. Frequently check the oil scale of small concrete mixer, regularly replace the oil and oil filter of concrete mixer, replace the spare parts of genuine oil filter, select the oil from the original factory, etc. can be used to avoid the phenomenon of oil burning of concrete mixer.

小型混凝土搅拌机的运用，为新农村建造立下了汗马功劳。运用小型混凝土搅拌机的用户越来越多，很多机械制造商也看到了这块肥肉纷繁做起了小型搅拌机。使得小型搅拌机的市场很紊乱，价格也是参差不齐，这就需求用户在选购搅拌车时要稳重。由于一辆小型搅拌车质量的好坏首要取决于上桩部分的好坏，车辆底盘部分都是相同的，不同企业的差异其实也不大。选购小型混凝土搅拌机时应留意的七个关键：

The application of small concrete mixer has made great contributions to the construction of new countryside. There are more and more users using small concrete mixers, and many machinery manufacturers have also seen the fat and started small mixers. Make small mixer Market is very disorder, the price is uneven, which requires users to be stable in the purchase of mixer. Because the quality of a small mixer mainly depends on the quality of the pile part, the chassis part of the vehicle is the same, and the difference between different brands is not big. Seven key points to pay attention to when purchasing small concrete mixer:

一、罐体钢材的材质及厚度。

1、 Material and thickness of tank steel.

二、罐体封头质量的好坏。

2、 The quality of tank head is good or bad.

三、罐体内叶片的结构好坏。

3、 The structure of the blade in the tank is good or bad.

四、混凝土剩余率。

4、 Concrete residual rate.

五、搅拌均匀度。

5、 Mixing uniformity.

六、进出料速度。

6、 Feeding and discharging speed.

七、塌落度规模。

7、 Collapse scale.

综合以上七点考虑，这样才能买到真正好的小型混凝土搅拌机。希望能帮到大家，更多问题请咨询我们莱工的网站吧~
