Before using the tanker, the following preparations should be done: Insert the conductive rod into the ground so that it is “grounded”. If it is dry, it can be watered to make it wet. Needs good protection and good grounding. And check the ground chain, so that it can make good contact with the ground; open the tank truck to manipulate the door, carefully check each valve handle, let it in a closed state; if it is the first time using the oil pump, then If there is no oil in the pump, you need to refuel in advance. You can add 10 liters of oil through the oil inlet. Check the oil screen in the tank car gearbox. The oil level is based on the bottom edge of the socket hole. When the amount of oil is insufficient, gear oil should be added in time.

1. The tanker cannot add gasoline to the carburetor port while it is cranking or when the engine is running. Adding gasoline to the carburetor can increase the concentration of the cylinder gas mixture, although this will be beneficial if the oil fails to enter the cylinder, but it does not help with the failure caused by other reasons. The situation may also result in tempering. In serious cases, there will be damage to burned people and burned vehicles.

2. The tanker should use gasoline to filter the core when maintaining the fuel filter. Some people prefer to use gas-fired ceramic filter cartridges to remove impurities from the filter element when they perform maintenance on the fuel filter. However, the danger of knowing such an operation method is extremely great. If a fire accident occurs, the consequences cannot be imagined. At the same time, such a method has a great influence on the service life of the filter element.

3. When the vehicle is in the oil depot, it cannot use the method of short-circuiting to check the storage condition of the battery. Because the ventilation in the oil depot is generally not very good, and some equipment such as batteries, tarpaulins, and tires will be prevented. If there is missing gasoline on the ground, the sparks generated during the fire fighting may cause The oil molecules in the air ignite.

4, the tanker dragging the subway chain can not eat around the girder. Because the oil and other materials transported by the vehicle are not the same, static electricity is sometimes generated when it is rubbed against another object. The static electricity may cause the fuel to ignite as long as it is a flash fire. Causes fire. Therefore, the bottom line of the oil depot needs to be grounded. The tanker should also be equipped with a grounded iron chain to prevent electrostatic sparks in the tank. The subway chain needs to be placed on the ground. The beam cannot be wrapped. IQ, and the lot can not be less than 50CM. (Text / Sun Ni)

Steel frame electric bicycles, processing performance, chromium-molybdenum steel is the oldest bicycle materials, the longest of its research, the processing technology has been developed to a very stable level. 2. Strength According to the conclusion of the car, it can be concluded that car enthusiasts can draw the conclusion that the strength of the same volume steel is much larger than that of aluminum alloy and titanium alloy, so the strength of qualified steel frame can be reassuring. 3. Take a comfortable, good steel elastic steel made of metal, can absorb the vibration when riding. Therefore, the steel frame will not be as uncomfortable as the aluminum frame, especially for the travel frame. 4. Steel metal fatigue stronger than aluminum, so the same conditions of use, the life of the aluminum frame longer life. Of course, the steel frame also has its insurmountable shortcomings: 1. Light weight, today in the pursuit of lightweight equipment, the quality of 7.8g / cm3 steel so that everyone does not encourage him. Although light steel construction, while pumping pumping technology wall is very thin, but the weight of the steel is difficult to reduce to 1600 grams or less. Many aluminum frame weighs only about 1400 grams. This is a competitive framework, rarely seen the reasons for the steel frame. 2. Rusted, relative to other materials, steel is relatively easy to rust. Rust can drastically reduce the strength of the steel, shortening its service life. (Such as BEARS these frames in order to prevent the problem of rust to the framework of the new tube coating), so we must take various measures to prevent rust.
