When a company launches a new product, it will pay great attention to the promotion of the product. The most common method of advertising is advertising, but more and more consumers have expressed that they have become numb and have no desire to read it. So led advertising car appeared. This is a hot publicity method in recent years, and many businesses will choose to advertise or advertise their own products by purchasing or renting a led advertising vehicle. However, when it comes to publicity, it is imperative that vehicle maintenance be done to ensure the safety of the vehicle. First of all, to check the location of all the pipe joints in the pipeline is in good condition, we must ensure that the joints at the pipe clamp fastening. Then go to see if the water block is rusty. If this happens, it means that there is oil or fuel leakage in this part. If it is not processed in time, it will cause damage to dryers and other parts, and it is very dangerous during driving. Once it is found that the water is rusting, it is necessary to immediately check the condition of the tubing to see if any cracks have occurred. If so, repair it and replace it immediately. Led advertising car will inevitably encounter rainy weather in the process of driving, we have to deal with drops of water and other places in time after driving. Because when the car is driving, the wheel will splash water on the ground, and bring it to the wire or sensor, etc. As the weight of the raindrop increases, the wire is likely to break along with it, causing a problem to the circuit or the vehicle. In order to avoid this security risk, we must pay attention to this point. As people's demands for advertisements increase, traditional propaganda techniques are far from satisfying consumers' needs. At this time, a new type of propaganda technique is needed to cater to customers. The led advertising vehicle can not only meet this point, but its speed and attractiveness are not inferior to traditional advertising marketing. But no matter how good the advertising effect of led advertising vehicles is, this is based on the integrity of the vehicle. In the process of use, it is necessary to pay attention to these basic precautions. To prolong the service life of advertising vehicles is to prolong the advertising time. Simply put, a single luozhu is a luozhu and two star wheels. When the screw is running at high speed, the air pulsation is small and the exhaust volume is large. Due to the force balance of the single screw, the maximum pressure of the first stage compression can be greater than that of the double screw; the single screw is more energy-saving than the double screw, and the bearing size is not as limited as the double screw type and has a longer life.
