Now in the summer, air conditioning is indispensable. I believe that the requirements for air conditioners are very high, but we should pay attention to the maintenance of the car air conditioning system when using it. If it is not used for a long time. It is very likely to bring us serious consequences, then how to properly maintain the car air conditioner, let's take a look at it.

During the use of the automotive air conditioning system, air flows in the blower, the refrigeration system evaporation tank, the small water tank of the heating system, and the air duct. As soon as the air conditioning system blower is turned on or the intake mode is selected to circulate indoors, air will enter the system regardless of whether or not the refrigeration unit is used. Over time, the surface of the above device accumulates a lot of dust, moisture, bacteria and other dirt, and causes damage and allergic reactions to the human respiratory system and skin, directly affecting the health of the occupants, and the air conditioning system itself may have poor cooling performance. The air volume is small and other faults. In general, the air conditioner filter is cleaned every 5,000 km or 3 months, and the air conditioner filter is replaced every 20,000 km or 12 months. This will ensure that you can enjoy a clean and clean car interior environment to ensure your health.

How to use car air conditioning system

1. First release the hot air and then turn on the air conditioner. If the car is parked for a long time under the scorching sun, do not use the air conditioner immediately after the vehicle starts. First open all the windows, start the outer circulation, discharge the hot air, and wait for the temperature inside the compartment to drop, then close the window and turn on the air conditioner. Air conditioners should not be turned on and off frequently to prevent damage to the air conditioning system.

2. When the air conditioner is turned on in the car, the driver should not smoke in the car. If smoking, please adjust the air conditioning ventilation control to the "outer circulation" position.

3. The air conditioning time after parking should not be too long. Some owners are cool, close the doors and windows, open the air conditioner to rest in the car, which can easily lead to increased carbon monoxide concentration in the car and poisoning.

4. Do not stack items near the air intake to prevent the air intake from being blocked, causing air circulation in the air conditioning system to be blocked.

5. Turn off the air conditioner a few minutes before reaching the destination (parking), turn on the natural wind later, and raise the temperature inside the air conditioning duct before parking to eliminate the temperature difference from the outside, thus keeping the air conditioning system relatively dry. Avoid the proliferation of a large number of molds caused by moisture. Need to pay attention to the general 1.3 liter or more displacement car, the air conditioning effect is basically OK, but some 1 liter or less liters of the mini car, due to the small engine power, the air conditioning effect is not ideal, even open the air conditioning to go a long way Water boiling can occur, especially on hot summer days. Therefore, there are two things to note in the summer air conditioning use: 1. If the engine is too hot due to the increased load on the air conditioner, suspend the use of the air conditioner until the water temperature is normal. Second, to avoid parking when using air conditioning for a long time in the summer at high temperatures, because the air conditioner can not be effectively cooled, it is easy to be damaged due to excessive system temperature and pressure.

First, how to choose the viscosity of the oil in summer?

In the summer, many car owners complain about the oil, in fact, in the summer, you can choose a lower viscosity lubricant, of course, this is also in the premise of better car conditions and less wear. For older cars with a longer number of kilometers, a car with a slightly longer age should still use a slightly more viscous lubricant.

Second, how to clean the air conditioning duct replacement filter?

The original air conditioning filter life of the car is changed once every 12,000 km, this is generally under normal circumstances. The method of cleaning the air duct is very simple. It is to block the air conditioner air outlet with a wet net towel, and adjust the air conditioner speed so that the dust will be sucked on the towel. In addition, air-conditioning duct cleaning agent can also be used to assist the high-pressure air gun cleaning 2 to 3 times for cleaning purposes.

Third, how should the airy mildew be cleaned up?

Some car owners will find that when the air conditioner is turned on, the air outlet will blow out a musty smell, which is because the air supply channel is not cleaned in time. The easiest way is to solve the problem by cleaning the air conditioning duct. As we mentioned above, the user can purchase an air conditioner cleaner to assist the operation. When the air conditioner is used, it should not be turned off immediately, but continue to turn on the air supply switch for 5 minutes.

In addition, the vehicle must pay attention to the use of the internal and external circulation system of the vehicle during the summer. Many models are now automatic air conditioners, while some models are manual air conditioners. At this time, we must pay attention. When the outer circulation is used, the air conditioner enters the air from outside the vehicle, while the inner circulation is the air circulation inside the vehicle.

The maintenance method of the car air conditioner is introduced here first. I don't know if everyone knows it. If the above situation occurs, it must be handled in time, and we must regularly maintain the car air conditioning system to prevent it from happening. Unnecessary consequences.

 

Guide Slider Introduction 1. Roller guide block is a precision linear rolling guide, with a high carrying capacity and high rigidity, the repeated action, start, stop the reciprocating frequency can be reduced in the case of high weight And transmission mechanism and power costs. 2. Roller guide block can get high sensitivity and high performance linear motion. In the case of heavy load or load, the elastic deformation is small and can get a smooth linear motion, no crawling. 3. Roller guide block because of its rolling body - roller in the rolling guide, and can automatically center, it can improve the positioning accuracy of the machine. 4. The roller in the roller guide block in the matrix in the circular motion, so the use of rolling rail block, not limited by the length of the machine bed, according to the size and selection of specifications to determine the number of rails. 5. Roller guide block application of a wide range of small size can be used in molds, instruments and other linear motion components, large size can be used for heavy machine tools, precision instruments of the plane linear motion, especially for NC, CNC machine tool. Basic structure: Roller guide block mainly by the body, the end cap, cage and rolling body and other components. One of the rolling body used for the roller. The rollers are constantly moving in the body and subjected to a certain load. Roller with a central guide, the movement can be automatically centering, so as not to shift, is conducive to movement under the load flexibility, and long life.
