Buried water tanks play an important role in many fields of water storage, in order to ensure its safe and stable operation, daily inspection and maintenance work is very important. The following is about the daily inspection and maintenance of the buried water tank in detail.
1. Daily inspection
1. Check appearance
Check the outside of the buried water tank regularly to see if there is obvious deformation, damage or corrosion. If the tank shell is found to have dents, cracks, etc., it should be repaired in time to avoid further damage resulting in water leakage.
Check whether the anti-corrosion coating of the water tank is intact, such as peeling, peeling and other phenomena, should be reapplied in time to prevent the erosion of the water tank by the underground environment.
Pay attention to observe the ground around the tank for any anomalies such as water, subsidence or uplift, which may mean that the tank has a leak or loose soil around it.
2. Check the water level
Check the water level of the buried water tank every day to ensure that the water level is within the normal range. The water level can be observed by a water level gauge or level sensor installed on the tank, or by manually looking at the overflow or inspection hole of the tank to determine the water level.
If you find an abnormal drop in water level, you should immediately find the cause, which may be a leak in the tank, a pipe break, or a large increase in water consumption. At the same time, pay attention to observe whether the water level is too high to avoid damage caused by excessive pressure of the water tank due to high water level.
3. Water quality check
Regularly test the water quality in the tank to ensure that the water quality meets the requirements of use. You can entrust professional water quality testing institutions for testing, you can also use simple water quality testing tools for preliminary testing.
Check the color, odor, turbidity and other indicators of the water quality. If the water quality is abnormal, measures should be taken in time to deal with it. For example, if the water is cloudy, it can be cleaned and disinfected; If there is an odor, you can check whether there is foreign matter into the tank or water purification treatment.
4. Check pipe connections
Check whether the connection between the buried water tank and the water inlet and outlet pipe is firm, and whether there is loosening and leaking. In particular, pay attention to check the flange connection of the pipeline, valve interface and other parts to ensure that the seal is good.
Observe whether the pipeline is deformed, cracked or blocked, etc. If there is a problem, repair or replace it in time. At the same time, pay attention to check whether the insulation layer of the pipeline is intact to prevent the pipeline from freezing and cracking in winter.
5. Check accessory devices
Check whether the auxiliary equipment of the buried water tank, such as the water pump, valve, pressure gauge, and flow meter, is running properly. Ensure that the motor of the pump runs smoothly, no abnormal noise, the valve switch is flexible, the seal is good, and the reading of the pressure gauge and flow meter is accurate.
Regular maintenance and maintenance of ancillary equipment, such as cleaning water pumps, replacing valve seals, calibrating pressure gauges and flow meters, etc., to ensure stable and reliable performance.
2. Daily maintenance
1. Clean and maintain
Clean the buried water tank regularly to remove dirt, sediment and impurities in the tank. High pressure water gun washing, chemical cleaning and other methods can be used to clean, but pay attention to choose the right cleaning agent to avoid corrosion of the water tank.
After cleaning, the tank should be disinfected to kill bacteria and viruses in the tank. Disinfectants such as bleach powder and chlorine dioxide can be used for disinfection to ensure the safety of water quality.
Keep the environment around the water tank clean and sanitary, avoid garbage, debris, etc. piling up around the water tank to prevent pollution of the water tank.
2. Anti-corrosion treatment
Because the buried water tank is in the underground environment, it is easy to be eroded by water and salt in the soil, so it needs regular anti-corrosion treatment. Corrosion protection can be achieved by applying anti-corrosion paint and installing cathodic protection system.
For the parts that have been corroded, it is necessary to repair them in time, remove the corrosion products, apply anti-corrosion paint or welding repair to prevent further expansion of corrosion.
3. Anti-freezing measures
In winter, it is necessary to take anti-freezing measures for the buried water tank to prevent the water tank and pipes from freezing and breaking. You can fill insulation materials around the tank, such as foam, rock wool, etc., to reduce heat loss.
For pipes and valves exposed to the ground, insulation sleeves and electric tracing belts can be used to keep them warm to ensure normal operation at low temperatures.
In extremely cold weather, the water level in the tank can be appropriately increased to improve the freezing resistance of the tank.
4. Security management
Set up obvious warning signs around the buried water tank to prevent personnel from accidentally touching or damaging the water tank. At the same time, regular inspection of the water tank should be carried out to ensure the safe operation of the water tank.
Develop emergency plans to rehearse and deal with possible emergency situations such as water tank leakage and rupture, so as to ensure that rapid measures can be taken in emergency situations to reduce losses.
Operators should be trained to improve their safety awareness and operation skills, strictly abide by operation procedures, and avoid accidents caused by human factors.
In short, the daily inspection and maintenance of the buried water tank is an important measure to ensure its normal operation and extend its service life. Through regular appearance inspection, water level inspection, water quality inspection, pipeline connection inspection and auxiliary equipment inspection, as well as cleaning and maintenance, anti-corrosion treatment, anti-freezing measures and safety management and other maintenance work, can effectively ensure the safe and stable operation of the buried water tank, and provide a reliable water source guarantee for production and life.
