Winter is a very season, so it is very important for the 1-side suction truck to safely pass winter. The necessary maintenance and maintenance are very important. Detecting the engine, tires, and light is common, but the detection and adjustment of heating, antifreeze, and braking systems are targeted. 1. The main function of the antifreeze is to prevent the 1-side suction truck from stopping. In the cold winter, when the cooling freezes and breaks the radiator and freezes the cylinder block or cover of the engine, the safety of the suction truck has a very important role. If it is a new car, it is usually not necessary to add antifreeze within two years because all the suction trucks have already been filled in the factory. If it is old, the previous year has been in high-quality antifreeze, that is, the freezing point, boiling point and anti-corrosion performance of antifreeze meet the requirements, and this year has not changed. However, the antifreeze in the suction truck has not changed for two years and it must be replaced. This is because, generally two years, the antifreeze that expires when the antifreeze expires will cause the cylinder to corrode and cause serious damage to the engine. In addition, in order to ensure that the freezing point of antifreeze is maintained at minus 25 degrees, if you change a cool place, you still need to reduce the freezing point of antifreeze. 2. The battery is most afraid of low temperature, and the capacitance of the battery capacitor is much lower than room temperature under low temperature environment. Therefore, before the cold season, the battery electrolyte should be supplemented, the battery terminals cleaned, and the protection of them coated with special grease to ensure a reliable start and prolong the battery life. If the 1-side suction truck is not needed during the open or cold week, the battery should be removed and stored in a warm room to prevent the icing from being damaged. 3, in addition to replacing antifreeze, safe winter, the owner should also pay attention to oil substitutes. Oil viscosity changes with temperature. At present, there are two kinds of "single-stage and multi-stage" oils on the market. Single-stage oils use a narrow temperature range. Viscosity levels are only applicable to part of this year's season and cannot be used throughout the year. 4. In the summer, many drivers tend to use purified water or tap water and detergents, glass cleaners, which are partly to save money (more use in the summer) and, on the other hand, are almost ready-made because they are easy to use. However, in winter, tap water glass cleaning fluid is still used, which is very dangerous. Once the temperature is too low, pure water, tap water, such as replacement often crashes, sometimes suddenly all the containers, so winter must replace the light, such as the original pure water change afraid of the frozen glass cleaning fluid. If you really want to save, you can use tap water and antifreeze 5:1 mixed liquid. 5, the thermostat is a function of the automatic control of the engine normal temperature, cold start, the engine can quickly warm up to reduce cylinder wear. Some summer temperatures are high, maintenance personnel take the thermostat down, although it can solve the summer problem, but in the winter. Without notice, it is possible for a small tube to waste a bucket of antifreeze.
Zinc Die Casting Valve Parts are a metal forming process in which molten zinc metal is put under pressure and injected into a die.
Zinc are alloys that have high strength and hardness, outstanding corrosion resistance,full recyclability, mechanical properties, high thermal and electrical conductivity and strength at high temperatures. Zinc alloys possess high dimensional stability for complex shapes and excellent thin walls. The cost of raw material is low.
