Maintenance method of Haier central air conditioning water pump not pumping water

First, Haier central air-conditioning pump does not pump water.

1. Cracks appeared in the inlet elbow, resulting in a small gap between the elbow and the pump center, allowing steam to enter the inlet.

2. There is water before the pump runs. Farmland irrigation seems to overflow from the drainage hole, and a small amount of steam remains in the pump casing or tap water pipe.

3. The packing of the water pump has been used for a long time, and the packing is too loose or damaged. A large amount of water is discharged from the gap between the pump sleeve and the filler, and external air enters the pump from the gap between the pump hole sleeve and the filler. Internally, it will endanger pumping.

4. The contact area between the upstream and downstream water supply pipelines and the pump in the downhill horizontal section should exceed 0.5%. Upward, steam will remain in the air inlet, which will reduce the vacuum value of the pump and water pipe and endanger water absorption.

5. In the long-term deep diving, the wall thickness is eroded by erosion holes, and the river surface after the pump continues to decrease. When this hole comes into contact with water, steam enters the pipeline according to this hole.

Second, Haier central air conditioning pump maintenance method does not pump water.

Insert; Full of water; Clean steam; Intensify through the depths; Increase the distance between walls to clear the vortex. Open the bottom valve of the water pump to eliminate the blockage, reduce the pipeline damage, reduce the relative installation height and improve the cavitation ability of the water level line.

3. How to use Haier central air conditioning?

1, turn on the central air conditioner.

When the central air conditioner is turned on normally, press the mode key to select the operation mode of central air conditioner such as refrigeration, heating, dehumidification or ventilation according to your own needs. Choose heating in winter, that is, the sun appears on the display screen to indicate heating, and cooling is used in summer. Snowflakes on the display screen indicate air conditioning and cooling.

2. Adjust the air outlet angle of air conditioner.

The switch of the central air conditioner can also adjust the angle of the air outlet, which can make the air distribution more uniform. When the central air conditioner is heating, the heating flow is light and easy to rise, so adjust the wind direction button to make the air outlet face down, so that the heating flow can be transported to all corners of the room, making heating more scientific and comfortable. When central air conditioning is used for refrigeration, the cold air flow is easy to sink. If the cold air flow is to cover the whole room, it is best to make the air outlet face horizontally.

3. Set the room temperature reasonably

When using central air conditioning, set a reasonable temperature, not too low or too high. The air temperature is around 25℃, which is the most comfortable temperature for human body. Also pay attention to adjust the temperature difference, indoor and outdoor temperature difference generally does not exceed 8-65438 00℃. The set value should be lower than the current indoor temperature during cooling and higher than the current indoor temperature during heating.
