Every day, 304 people die from indoor pollution. It is not an alarmist. It is especially important for air-conditioning cleaning of one of the "culprits". When cleaning, do not leave a dead angle and kill the bacteria in the cradle. However, air conditioners have different ways of cleaning due to different styles and brands. Therefore, it should be carried out in strict accordance with the product instruction manual during cleaning and disinfection. Of course, it is best to ask professional and technical personnel to use special equipment and special air conditioner cleaners.
Five key parts for air conditioning maintenance in summer
1. Cleaning of the outer casing and filter
When cleaning, first wipe the air conditioner case with a rag, then open the case, remove the filter, use a clean filter brush to clean most of the dirt attached to the filter, and then put the filter into warm water. After a while, use a running tap water to rush the filter several times, slowly dry it with a clean rag, then put the washed filter back into the air conditioner and close the air conditioner. Note that the water temperature during cleaning should not exceed 50 °C. It is best not to use detergent, detergent, gasoline, banana water, etc., in order to avoid deformation of the filter; in addition, do not use a sponge to clean, because it will damage the surface of the filter.
2, the cleaning of the evaporator
The evaporator is also known as a cold heat exchanger. When the air conditioner is working, the evaporator takes away the hot air in the room and sends the cold air. Although the evaporator has filter protection, 80% of the dust passes through the filter and sticks to the wet evaporator. These places are the most susceptible to the growth of germs and mites, and affect the normal operation of air-conditioning, so it is the part of the air-conditioning that needs to be cleaned.
At present, there is a special evaporator cleaning agent on the market. After using the cleaning agent, it is evenly sprayed on the air inlet surface of the air conditioner evaporator. If there is too much dirt, it can be wiped off with a damp cloth and then rinsed with a small amount of water. However, it should be noted that the evaporator must be dried after the cleaning is completed.
3, the air outlet and roller cleaning
The idle air conditioner can easily collect dirt on the air outlet and the roller, and sometimes even block the air outlet. In particular, there are many grooves and gaps on the roller. If it is blocked, it will affect the air volume and easily breed mold. To clean these two places, you must brush them with a brush. At present, there is a professional transparent air-conditioner cleaning cover, which can be cleaned simply and thoroughly after being covered with a high-pressure water gun.
4, air conditioning heat sink cleaning and disinfection
It has just been mentioned that the heat sink is the most concentrated part of the bacteria. Therefore, it is very important to carry out careful and thorough cleaning and disinfection of the heat sink. It is understood that cleaning air conditioning radiators requires the purchase of professional air conditioning disinfectants. When cleaning is performed, first turn off the air conditioner power supply, then open the air conditioner surface panel, remove the filter net, air purification filter, and you can see the heat sink. Then, the disinfectant was shaken, and the heat piece was dispersed about 5 cm, and the entire heat sink was sprayed in the order of the top and bottom.
Wait for about 15 minutes, install the filter, and then run the air-conditioning refrigeration program for 15-30 minutes, so that the sewage will be discharged automatically with the drain. After disinfection, the door and window should be opened for about half an hour. Use the ventilation function until the residual disinfectant has evaporated, before it can be put into normal use.
Experts said that cleaning air-conditioning radiators is a professional work, and should be done as much as possible by professionals; in the choice of air-conditioner disinfectants, we should pay attention to the selection of products with national safety certification and disinfection size, so as to fully guarantee disinfection. Sterilization effect and human health and safety.
5, the cleaning of the condenser
The external machine generally does not need to be disassembled and cleaned, and the disassembly and cleaning is likely to cause mechanical failure and leakage of fluorine. The finned aluminum foil fins of the outdoor unit can be directly washed up and down with a tap pipe, or brushed with a long brush under the water. The condenser is installed between the exhaust port of the compressor and the electronic expansion valve, and the high-temperature and high-pressure gas discharged from the air-conditioner compressor enters the condenser, and is cooled by the copper tube and the aluminum foil. Here, if dirt accumulates, it will affect the normal operation of Freon and various components.
At present, there is a special condenser cleaning agent on the market, which can be used directly after being bought back. Of course, the condenser can also be washed directly with a tap pipe or brushed with a long brush on the water.
Hejian Deris Both manufacturer and distributor, specialize on Single Cone Bit The diamond compound teeth are used on the top of the YC single-cone bit to enhance the wear resistance of the teeth and improve the service life of the drill. The new hydraulic structure improves the cleaning ability of the hydraulic system for the cone and the bottom of the well and optimizes the flow field at the bottom of the well. The bit body of the bit body is made of a large-diameter active cutting ball head tooth, which makes the bit have a good diameter keeping function and a reverse eye function
TCI single cone bit Structural features:
1. The two-stage diameter of the cone and the bit body is adopted. The active cutting teeth and the passive anti-wearing teeth are mounted on the bit body, and the drill bit has better diameter-preserving effect and inverted eye function.2. The teeth of the cone are staggered, and the shape of the cone, the number of rows of teeth, the number of teeth, and the height of the dew are all preferred.
3, the hydraulic system uses the main and auxiliary two-eye structure, using jet and diffusion cleaning two types of nozzles to optimize the nozzle combination.
4. The large and small shaft seals of the drill bit bearing adopt advanced high-saturated nitrile rubber ring, optimized sealing compression and special diameter-proof structure design, ensuring high reliability of bearing seal.
5. The surface of the bearing of the tooth is welded with a hard metal layer, and the inner hole of the toothed wheel is welded with a wear-reducing alloy to improve the working ability of the bearing.
6, the use of steel ball locking cone, can adapt to high speed.
