The annual review of automobiles, as the name suggests, is an annual medical examination. According to the relevant regulations, every vehicle with a license plate and driving license must undergo a test every year, eliminate vehicle safety hazards in a timely manner, supervise and strengthen the maintenance of vehicles, and reduce the occurrence of traffic accidents. Many people today are aware of the importance of the annual inspection of automobiles. However, they are defeated in the cans that cannot be passed once because they overlooked something unexpected. Therefore, before the annual review, the owners should make these preparations. First, confirm whether the vehicle is illegal Many vehicle owners will prepare the necessary materials before the vehicle inspection. At this time, the energy is concentrated on the vehicle's identity data, and the untreated violations are often ignored. According to the regulations, violations are not removed in a timely manner, although they can be tested in terms of appearance, exhaust, etc., but the final “check†word mark must be processed after the violation is completed. Second, confirm whether the insurance is valid It is believed that everyone should be familiar with the original insurance when carrying out the annual review. However, some car owners, the time for annual review and the expiration of insurance are a time. It should be noted here that many friends continued the new one before the expiration of the insurance. In the year of insurance, the old insurance may not be expired when the vehicle is inspected. The new insurance has not yet come into effect. At this time, the original insurance policy that is still within the validity period must be carried, that is, the old policy is used to inspect the vehicle. Otherwise, the insurance that does not become effective will not be used. Annual review. Third, confirm the carrying tool Fire extinguishers, triangle cards, and tools are needed. The triangular warning sign is a passive reflective body made of plastic reflective material. When the driver encounters a sudden failure on the road to stop overhauling or an accident occurs, the reflective performance of the triangular warning sign can be used to remind other vehicles to pay attention to avoidance. In order to avoid secondary accidents. Finally, to remind the owner of the attention of the owner is that in the detection of on-line exhaust gas, in the external inspection area in advance to start the vehicle to warm up. Because the gasoline vehicle exhaust gas detection is related to the normal operation of the oxygen sensor and the three-way catalytic converter, and the optimal working temperature of the oxygen sensor and the three-way catalytic converter is 400 to 800 degrees Celsius, it is better to carry the vehicle for a one-time pass. Warm up.
1.WORKING PRINCIPLE
Double-tapped rotary vacuum dryer is a double conical rotary tank, the tank in the vacuum state, into the jacket through steam or hot water for heating, heat through the tank wall and wet material contact. Wet material after heat evaporation of water vapor, through the vacuum pump through the vacuum exhaust pipe is pumped, because the tank is in a vacuum state, and the tank rotation of the material constantly up and down, inside and outside, so accelerate the drying speed of the material, improve drying efficiency, to achieve the purpose of uniform drying
2.FEATURES
It is a drying equipment integrating mixing and drying. The condenser, vacuum pump and dryer are matched to form a vacuum drying device (if there is no need to recover solvent, the condenser can not be used). The internal structure of the machine is simple, easy to clean, easy to operate, can reduce labor intensity and improve the working environment. At the same time, because the container itself rotates when the material also rotates, but there is no material on the wall, so the heat transfer coefficient is higher, the drying rate is large, not only save energy, and the material drying uniform and full.
3.MAIN APPLICATION
It is suitable for vacuum drying and mixing of powder and granular materials in pharmaceutical, food and chemical industries, especially for materials with the following requirements
Heat-sensitive materials that cannot accept high temperatures
Oxidized and dangerous materials
Materials requiring recovery of solvents and toxic gases
Materials with very low residual volatile content are required
Material with requirements for crystalline shape
In addition we also have other machines for u chosoe,such as spices Powder Pulverizer ,powder mixer,Capsule Filling Machine,capsule Polishing Machine,Capsule Counting Machine,tablet press,vacuum dryer etc
