Problems and solutions of Semi Trailer

      In general, semi trailers will encounter the following problems during driving:

      1、 Frequent start and stop, resulting in rapid engine wear; Driving in cities is inevitable, and it is common to stop and walk. It is inevitable to drive fast, slow and take the same line. Generally speaking, new cars will gradually appear in the city for 2-3 years or so, such as insufficient power, low handling sensitivity and noise. These phenomena are related to frequent starting and stopping of the car and causing engine wear. Therefore, small repairs are often carried out, and the money and time are spent. But few people know that when the car starts and stops frequently, the gasoline is not fully burned, which is easy to produce a large amount of carbon deposition, accelerate the oxidation of lubricating oil, resulting in the failure of lubricating oil and loss of its proper lubrication protection performance.

      2、 Fuel is also the key to affect the engine life; The fuel selection must conform to the brand specified in the vehicle, and low grade fuel is prohibited. Otherwise, the engine will knock when working, which will cause strong impact on the parts and increase the additional load of the parts, thus accelerating the wear of the parts. The high temperature, high pressure and shock wave caused by detonation will destroy the lubricating oil film on the cylinder wall and worsen the lubrication of the machine parts. The test results show that the average wear of the cylinder upper part is more than twice that of the non knock engine when the engine works for 200H under the condition of detonation and no detonation. In addition, the fuel containing impurities exceeding the standard can also accelerate the wear and corrosion of the parts.

      Before the semi-trailer is traveling, safety inspection shall be done. But on the way, it is inevitable to encounter unexpected situations. If you are driving to a place where there is no village before or after the store, there is a problem, that is called trouble. If you master some common problems and emergency treatment methods, you will solve a lot of problems, at least you can solve the urgent problems. Here are some common problems and emergency solutions for the friends.

      1. The oil pipe is broken. If the oil pipe breaks during the driving of semi-trailer, a rubber tube or plastic pipe suitable for the diameter of the tubing can be found, which can be temporarily connected, and then the two ends shall be tied tightly with wire.

      2. Oil leakage from the oil pipe joint. The cotton yarn cloth can be used to wrap it around the lower edge of the horn, and then tighten the oil pipe nut and the oil pipe joint; Bubble sugar can be applied to the position of the nut seat of the oil pipe, which can play the role of sealing.

      3. The trailer leaks oil and leaks. According to the size of sand hole, the electrical fuse of corresponding specification can be selected and it can be smashed into the sand hole gently, so as to eliminate oil leakage and water leakage.

      4. When using the motor vehicle, oil tank leakage is found and oil tank damage occurs, wipe the oil leakage area clean, and apply bubble sugar to the oil leakage place, and temporarily block.

      5. The inlet and outlet hoses are broken. If the location of the fracture is small, the broken place can be wrapped with soap on the cloth drawing; If the position of the fracture is large, the broken part of the hose can be cut off, and a bamboo pipe or iron pipe shall be set in the middle and bound with wire.

      6. The valve spring is broken. The broken spring can be removed and the broken two sections can be installed in turn, and then it can be used. If the spring is broken into several sections, the adjustment screws of the inlet and exhaust valves of the cylinder can be removed to close the valve.

      7. The fan belt is broken. You can use wire to connect the broken belt or stop for a while to drive the car away.
