How to maintain a garden fogging system

The garden fogging system can create a dreamlike landscape effect for the garden, and at the same time, it can regulate the local climate and increase the air humidity. To ensure its long-term stable operation and good effect, comprehensive and meticulous maintenance is required. The following are the specific maintenance contents:

Daily inspection

Visual inspection

Inspect the pipelines: Check the pipelines of the fogging system every day to see if there is any damage, leakage, deformation or other conditions. Just like checking the water pipes at home, once cracks or loose joints are found in the pipes, it may lead to water leakage, which not only wastes water resources but also may affect the normal spraying effect of the fogging system.

Check the nozzle: Observe whether the nozzle is clogged, damaged or tilted. The nozzle is a key component of the fogging system for spraying. If it is clogged with dust and impurities, it cannot spray normally. If the nozzle is damaged or tilted, it will cause changes in the direction and range of the spray, affecting the landscape effect.

Operation status monitoring

Listen to the sounds of the equipment: When the system is running, carefully listen to the operating sounds of equipment such as water pumps and motors. Under normal circumstances, the operating sound of the equipment should be smooth and uniform. If abnormal noises occur, such as sharp friction sounds or dull knocking sounds, it may indicate that there is a problem with the equipment and it is necessary to stop the machine immediately for inspection.

Observe the pressure gauge: Pay attention to the changes in the pressure gauge's readings to ensure that the system pressure is within the normal range. Excessive pressure may damage the pipes and nozzles, while insufficient pressure will result in poor spraying effect. For instance, if the pressure drops suddenly, it might be due to a malfunction of the water pump or a leak in the pipeline.

Regular cleaning

Water tank cleaning

Cleaning cycle: It is recommended to clean the water tank every 1-2 weeks. The water tank is a place for storing water. After long-term use, the inner walls of the water tank will breed impurities such as scale and algae, which will affect the water quality and, in turn, the spray effect and the service life of the equipment.

Cleaning method: First, drain the water from the water tank, then rinse the inner wall of the water tank with clean water to remove the dirt on the surface. For stubborn scale, a dedicated scale cleaner can be used for cleaning, but attention should be paid to the amount of cleaner used and the cleaning time to avoid corrosion to the water tank. After cleaning, rinse repeatedly with clean water to ensure there is no detergent residue in the water tank.

Nozzle cleaning

Cleaning frequency: Depending on the water quality, clean the nozzle once every 1-2 weeks. If the water quality is poor and contains a lot of impurities, the cleaning frequency should be appropriately increased.

Cleaning steps: Remove the nozzle from the pipe, soak it in clean water for a period of time, and then gently scrub the filter screen and spray holes inside the nozzle with a soft-bristled brush to remove the clogged impurities. For some nozzles that are difficult to clean, an ultrasonic cleaner can be used for cleaning. After cleaning, let the nozzle dry before reinstalling it.

Filter cleaning

Cleaning timing: When the system spray volume decreases or the pressure is unstable, it may be that the filter is clogged. At this time, the filter should be cleaned in a timely manner. Under normal circumstances, the filter should be cleaned every 2 to 4 weeks.

Cleaning operation: Turn off the system power and water supply, remove the filter, take out the filter element inside the filter, and rinse the impurities on the surface of the filter element with clean water. If the filter element is damaged or severely clogged and cannot be cleaned thoroughly, a new filter element should be replaced in a timely manner.

Equipment maintenance

Pump maintenance

Lubrication and maintenance: According to the user manual of the water pump, regularly add lubricating oil to the bearings and other components of the water pump to reduce friction between components and extend the service life of the water pump. Lubricating oil is generally added once every 3 to 6 months.

Check the seals: Regularly inspect the seals of the water pump, such as mechanical seals and packing seals, to ensure good sealing and prevent water leakage. If wear or aging of the sealing parts is found, they should be replaced in time.

Motor maintenance

Clean the motor surface: Regularly wipe the motor surface with a clean soft cloth to remove dust and debris and ensure good heat dissipation of the motor. Dust accumulation can affect the heat dissipation effect of the motor, causing the motor temperature to be too high and affecting its normal operation.

Check the motor wiring: Inspect whether the motor wiring is loose or aged to ensure it is firm and reliable. If the wiring is loose, it may cause the motor to operate with a missing phase and damage the motor.

Winter protection

Drain the accumulated water: Before winter arrives, it is necessary to drain the accumulated water in the pipes, water tanks, water pumps and other equipment of the fogging system to prevent the water from freezing and expanding, which may damage the equipment. Just as the water pipes at home need to be drained of accumulated water in winter, the fogging system also requires proper anti-freezing measures.

Equipment protection: For equipment exposed outdoors, insulation materials such as insulation cotton and foam boards can be used for wrapping to reduce heat loss and protect the equipment from the influence of low temperatures. Meanwhile, in extremely cold weather, the fogging system can be temporarily suspended and restarted when the temperature rises.

Replacement of consumables

Filter element replacement: Replace the filter element regularly based on its service life and water quality conditions. Under normal circumstances, the PP cotton filter element should be replaced every 3 to 6 months, the activated carbon filter element every 6 to 12 months, and the ultrafiltration membrane filter element every 1 to 2 years. Timely replacement of the filter element can ensure the filtration effect and extend the service life of the equipment.

Nozzle replacement: If the nozzle still cannot restore its normal spraying effect after multiple cleanings, or if the nozzle is severely damaged, a new nozzle should be replaced in a timely manner. The replacement cycle of the nozzle depends on the usage frequency and water quality conditions. Generally, it should be replaced every 1 to 2 years
