Today, Xiaobian will tell you how to judge whether your fully automatic mixer works normally, as follows:
1. Sudden changes in the working conditions of the mixer:
The so-called sudden change in general working condition refers to the sudden abnormal phenomenon in the working condition of the mixer, which is a relatively common fault symptom. For example, it is difficult to restart the mixer engine after it suddenly stops, or even cannot start; The power of the mixer engine suddenly decreases during driving, and the driving is weak; Sudden brake failure, deviation or even failure during driving. The symptoms of this fault are obvious and easy to detect.
2. Abnormal noise:
The abnormal sound of the mixing truck during driving is the "alarm" of the mixing truck fault. When a strange noise is suddenly made during driving, the driver should realize that there is something wrong with the mixer, and should stop immediately for inspection. Remember not to let the mixer "work with disease".
3. Abnormal exhaust smoke color:
The main components of the normal combustion products of the fully automatic mixer engine during operation should be carbon dioxide and a small amount of water vapor. If the engine of the mixing truck burns abnormally, the exhaust gas will be mixed with unburned carbon particles, hydrocarbons, carbon monoxide and a large amount of water vapor. In addition, there are nitrogen oxides and so on. At this time, the color of exhaust gas may become black, blue or white, which means that the color of exhaust smoke is abnormal. For gasoline engines, there should be no obvious smoke in the normal exhaust gas. However, when the lubricating oil moves up the cylinder, the tail gas is blue; When the combustion is incomplete, the tail gas is black, and when the oil is mixed with water, the tail gas is white.
4. Overheating and high temperature:
It usually appears on the assembly of mixer engine, transmission, drive axle main reducer, differential and brake. For example, the engine of the mixing truck is overheated, which is mainly due to the problem of the cooling system, the lack of coolant or the failure of the pump; The transmission and drive axle are overheated, mostly due to lack of lubricating oil; The brake overheat is mainly caused by the brake shoe not returning. The above phenomena can sometimes be directly reflected by the warning light on the instrument panel, which requires the driver to pay attention to the observation when driving, and can also test the external temperature by hand.
The leakage of concrete mixer refers to the leakage of fuel, lubricating oil (or gear oil), brake fluid (or compressed air) and power steering system oil of the mixer engine. This is also an obvious fault symptom, which can be found by careful observation. For example, when compressed air leaks, the sound of air leakage can be heard clearly.
In addition, the excessive consumption of fuel and lubricating oil in the mixer truck indicates that the technical condition of the mixer truck has deteriorated and has caused failures. For more matters related to the mixer, please visit our website http://www.zkzsljbc.com Ask!
