The application of cement mixer is more and more extensive, and its type is also gradually increasing. The common ones are natural gas coagulator, air suspension coagulator and frameless coagulator. In the process of using the cement mixer truck, regular maintenance shall be carried out for the mixer truck, but there are three parts, which cannot be maintained frequently. First of all, do not overuse the fuel booster, wash the car frequently, or change the oil. Here is a detailed introduction.
1. Natural gas concrete mixer
The natural gas concrete mixer is divided into LNG (liquefied natural gas) concrete mixer and CNG (compressed natural gas) concrete mixer. Since 2013, the number of licensed natural gas hybrid vehicles has been increasing all over the country. The reason for the rapid development of natural gas is that the popularization of natural gas and people's increasing awareness of environmental protection are inseparable. The LNG concrete mixer is arranged with side mounted gas cylinders, which does not affect the loading part of the concrete. CNG concrete mixer adopts the rear barrel, which is placed behind the cab.
2. Concrete mixer
According to the new regulations, the total mass can only be increased to 1000 kg in air suspension configuration. Air suspension can reduce the impact of concrete on the concrete in the tank during transportation, and ensure the quality of concrete when it is transported to the site. At the same time, it can reduce tire wear, fuel consumption, weight loss, improve work efficiency, save money and safety.
3. Concrete mixer without secondary frame
Before that, the traditional concrete mixer consisted of a set of frame, a mixing drum, a hydraulic system, a water supply system, a feeding and feeding equipment. If the capacity of the mixing drum is too large, it will increase in the middle, and the stability of the trolley will be poor. If you drive on uneven roads, it's easy to overturn. This is mainly because the moving mixing cylinder is rotating at the same time, and the concrete in the cylinder will cause the center of gravity to shift in a certain direction when the vehicle rotates.
Three parts of cement mixer can not be maintained regularly
1. Excessive use of fuel combustion supporting agent
Some people think it can save gasoline, improve combustion efficiency, clean carbon and keep the engine clean for a long time; others think it is not very useful. In fact, the effect of additives is not as powerful as advertised. The fuel consumption and power performance of engines are fixed and cannot be changed under the effect of additives. If additives are used blindly, it may backfire and bring unnecessary burden to the engine.
Wash the car often
It is very common that there are stains on the mixer body, which is a common problem of concrete. Some careful car owners wash the car almost once a day, which is unnecessary. Frequent car washing can easily cause damage to the car surface
3. Change oil frequently
After driving for several kilometers, the oil in the tank needs to be replaced to remove the carbon deposit and ensure the normal operation of the engine. In the actual driving process, some owners change the oil cycle too short, which is a waste of money, and may cause excessive oil into the combustion chamber, damage the engine.
