The performance of tanker faults, due to their different causes and characteristics, can be summarized as follows:
1. The situation of the job changed dramatically
The so-called changes in operating conditions mean that the operation of the tanker suddenly showed an abnormal appearance, which is a comparison of common problems. For example, if the engine suddenly turns off, it will be difficult to launch, and even if it cannot be started, the power in the engine will suddenly decrease and its power will be weak. In the process, the engine will suddenly fail to brake or run, and even fail. This is a manifestation of this problem and it is easy to detect.
2, abnormal sound
The abnormal movements that occur during the movement of the tanker are the “alarms†of tanker problems. During the course of the march, a strange noise was announced. As a driver, he should be aware that the car was out of doubt and should be immediately parked to view the vehicle. The vehicle must not be allowed to “sick upâ€.
3, exhaust smoke is not normal
During the operation of the engine, the main components of normal incineration products should be carbon dioxide and a small amount of water vapor. If the engine is not properly burned, the exhaust gas will be incinerated with carbon particles, hydrocarbons, carbon monoxide and a lot of water vapor. In addition, there are nitrogen oxides, etc. The color of the exhaust gas can be turned black, blue, or white, which means that the exhaust smoke is abnormal. With regard to the gasoline engine, normal exhaust gas should be free of significant smoke. However, when the smooth oil is smashed on the cylinder, the exhaust gas is blue; when the incineration is incomplete, the exhaust gas is black, and when the oil is mixed with water, the exhaust gas is white.
4, high temperature
It is generally presented on the engine, transmission, drive axle main reducer, differential and brake assembly. For example, if the engine is overheated, there are doubts about the cooling system. It is the lack of coolant or the pump is not in operation; the transmission and the transaxle are overheated, mostly caused by the lack of smooth oil; the brakes are overheated, and most of the brake shoes do not return. . The above image can sometimes be directly reflected by the dashboard warning light. The driver is required to pay attention to the investigation while driving, and the surface temperature can also be tested by hand.
5, leakage
Leakage refers to the leakage of oil, oil (or gear oil), brake fluid (or compressed air), and power steering fluid of the tanker engine. This is also a significant problem and can be discovered by careful investigation. For example, when the compressed air leaks, the air leakage sound can be heard significantly.
6, fuel and smooth excessive consumption
Excessive fuel and oil consumption, indicating that the tanker skills have deteriorated and has caused problems.
7, there is a special smell
When the tanker is in operation, if there are any problems such as brake drag, slippage, etc., it will disperse the burnt smell of the friction plate; when the engine is overheated and the oil tank burns, it will divergence and announce a special odor; When the ground wire is burned, it will also have a burnt smell.
8. Abnormal appearance of the tanker
The tanker truck is parked on a flat site to see the appearance of the tanker . If there is a horizontal or vertical tilt, the appearance is abnormal. Most of the reasons are flaws in the frame, body, suspension, tires, etc. This can lead to problems such as instability in direction, deviation, center-of-gravity handling, and wheel “gestureâ€.
It can be prepared by directly crushing natural calcite, limestone, chalk, shell, etc. by mechanical methods (using Raymond mill or other high-pressure mill). Because the sedimentation volume of heavy Calcium Carbonate is smaller than that of light calcium carbonate, it is called heavy calcium carbonate.
Heavy calcium carbonate is abbreviated as heavy calcium. It uses high-quality limestone as raw material and is processed into white powder by a lime mill. Its main component is CaCO3. Heavy calcium has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Heavy calcium is usually used as a filler. It is widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. Increase the volume of products and reduce production costs. Used in rubber, it can increase the volume of the rubber, improve the processability of the rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of the rubber.
