Basic maintenance knowledge and principle of children's toy prototype model

basic maintenance knowledge and principle of children's toy prototype model the train prototype model is not only a delicate collection of toys, the shape is also completely copied according to the era of trains in various countries. It is true and historic. Most of the shells are made of engineering plastic ABS, with built-in exquisite motors and metal pressure, which are reduced proportionally. The railway is also reduced according to the proportion of the real Railway, which is made of alloy pulling. The current is about 12 volts passed through the controller to the front motor after the railway. The model train will move like a real train, it can speed forward and backward. If there are lights, it will shine or follow the train to change the lights. Some can also be combined with sound effects or smoke like real trains. Basic maintenance common sense of train prototype model: 1. After the track is used for a while, the oil used on the train prototype model will adhere to the dust in the air, resulting in a layer of dirt on the track surface, generally, the track surface and the contact surface of the train prototype model with power wheel and track can be wiped with cotton-free cloth. 2. The general train prototype model has a dynamic front car. When driving for a while, you must regularly add lubricating oil to the gear rotation depending on the car model. Lubricating oil can be purchased in general model stores and can be applied to dynamic models such as car models. Driving principle of train prototype model: most of them use the way the track is powered on, and plug in the power supply in the home can be easily used. Generally, it is powered on by the track. The main surrounding area is equipped with a controller, also known as the fire cow, with a pressure change and a wire and track connecting the track. However, there are exceptions to LiveSteam, which is used to drive the train prototype model. Like a real train, it is generally used on a large size train prototype model. The main purpose is to use gas or alcohol to ignite the water of the combustion boiler. Some of them are to use real coal but to break the coal in advance, which is quite authentic and interesting, however, most of these train prototype models are quite expensive in unit price, because such models are quite accurate in manufacturing, especially in boiler and cylinder parts, moreover, the use and maintenance are quite complicated and technical. Such products usually price in 0. 15 million 0. 3 million yuan RMB about.
