[Excavator air conditioner] Why the excavator air conditioner does not blow cool air

What is the important role of excavator construction in summer? The answer must be air conditioning! Even if it is very hot outside, the car must be a cool breeze inside the cab, the obvious degree of comfort is important to the driver's successful engineering construction. Excavator air conditioning.

We all know that in the hot summer excavators are indispensable to air conditioning, but if air conditioning if there are problems in the case of fire, most of them can not work, so be sure to repair and maintain the air conditioning before the excavator into the dog days of summer, in order to give full play to the greater effect. Excavator air conditioning.

Notes for air conditioning maintenance:

In hot summer, after turning on the air conditioning, open all the Windows and doors of the driver's cabin, wait 2-3 minutes before getting out of the car, and then return to the car to prevent injuries caused by high temperature.

If the air conditioning filter element or filter net is blocked, it will immediately harm the air flow of the air conditioning. If there is no long-term replacement, the air flow will be too small, the smell is too large, and the bacteria will grow. After a long time, it will harm the physical and mental health of the driver.

Remove the air conditioner cooler immediately. If blocking will harm the cooling effect of the air conditioner, if the cooler is too dirty, you can use a high pressure water pump to clean and clean it.

Regular maintenance of air conditioning refrigeration compressor belt support, generally every 250 hours check, belt tension should be about 10mm, if the belt is too loose not only loud noise, but also sound, cooling effect is poor.

It is necessary to maintain the refrigerant regularly. The height of the refrigerant level meter will also harm the refrigeration effect of the air conditioner (all normal working pressure bottom pressure 1.5-2kg/cm2 high pressure 13-17kg/cm2). Excavator air conditioning.
