1. Before starting the tractor, inject 75~85°C hot water into the water tank to warm up the body and prohibit starting with an open fired roasting car or dry water without cooling water. This not only exacerbates the wear of the locomotive, but also prone to accidents such as fuel tank explosion and body cracking. When the engine is not warmed up and the hot water is not being filled, preheating and starting with the starter are prohibited.
2. When the tractor stops working in a short time, it should be noted that the temperature of the cooling water must not be lower than 40°C, otherwise the engine should be operated at a low speed.
3. After each class of tractor work, park it in a flat place until the water temperature drops to 50 ~ 60 °C, open the water tank drain valve, put the water into the bucket, and continue to use it after heating the next day. When cranking, the crankshaft should be cranked so that the water in the pump housing can be drained. The water must not be released from the net to prevent freezing of the drain valve.
4. Before adding the antifreeze, the scale of the cooling system must be removed; the added amount of cooling water should not be too full, and various antifreezes cannot be mixed; antifreezes do not leak when used, because some antifreezes are flammable and some antifreezes are toxic. Therefore, operators should pay attention to safety.
Small 125mm led Traffic Light simulation teaching traffic light characteristics of decorative traffic lights
1. The 125-type traffic light adopts the C125MM lamp tube that our company has independently opened the mold, with a moderate size and a unique shape.
2. The 125 type traffic light adopts Taiwan Epistar chip lamp beads, which is bright, eye-catching and distinct in color.
3. The bottom of the 125 type traffic light adopts a waterproof connector for outlet, which has a good waterproof effect.
4. The 125 type traffic light adopts bracket installation, which is simple to operate and easy to install.
Install small LED traffic lights, simulate teaching traffic lights, and pay attention to when decorating traffic lights:
1. At an intersection with a guide lane, drive into the guide lane according to the required direction of travel;
2. Those who are ready to enter the roundabout let motor vehicles that are already in the intersection go ahead;
3. When turning to the left, turn to the left of the center of the intersection. Turn on the turn signal when turning, and turn on the low beam when driving at night;
4. When meeting the release signal, pass in turn;
5. When the stop signal is encountered, stop outside the stop line one by one. If there is no stop line, stop outside the intersection;
6. When turning right when there is a car in the same lane waiting for the release signal, stop and wait one by one;
7. At intersections with no direction indicator lights, turning motor vehicles let straight vehicles and pedestrians go first. Right-turning motor vehicles traveling in the opposite direction let left-turning vehicles go first.
