Large-flow water pumps are mainly machines used to transport liquids or pressurize liquids. For example, it can be used to transport water, oil, acid and alkali liquids and liquid metals, etc., and can also be used to transport liquids such as liquids and gas mixtures. It transfers the mechanical energy or external energy of the prime mover to the liquid, so that the liquid energy increases rapidly.

Before the high-flow water pump works, the pump body and the water inlet pipe must be filled with water to form a vacuum state. When the impeller rotates rapidly, the blades make the water rotate rapidly, and the rotating water flies out of the impeller under the action of centrifugal force. After the water is thrown out, a vacuum zone is formed in the central part of the impeller. The water in the water source is pressed into the water inlet pipe through the pipe network under the action of atmospheric pressure (or water pressure). This enables continuous pumping.

1. If the oil bearing uses lubricating oil, during the use of the water pump, it is necessary to observe whether the oil level is within the range of the oil mirror mark every time. If the oil is not enough, add oil through the oil filling cup, and clean and change the oil once a year.

The bearings are lubricated with grease (commonly known as butter). During the use of the water pump, the oil should be changed every 2000 hours of operation. Calcium-based grease is best used for lubricating grease, and high-grade bearing grease can also be used.

2. Replace the shaft seal

"Because the packing will wear out after a period of time, when water leakage or excessive leakage is found, it is necessary to consider whether to press or replace the shaft seal. For the shaft seal using ordinary packing, the leakage should generally not be greater than 30-60ml/h, while The leakage of the mechanical seal should generally not be greater than 10ml/h. The mechanical seal of this system can ensure that it runs for 8000 hours without water leakage under the condition that it meets the water quality of the clean water pump. Whether there are impurities, rust, etc. in the circulating water, or poor installation of seals, etc.;

3. Rust paint

When the water pump is in use, it is usually in a humid environment. Some frozen water pumps without thermal insulation treatment are covered by water (due to condensation) on the surface of the pump body during operation. For a long time, part of the surface of the pump body will be Rust, for this reason, the surface of the pump body of the chilled water pump that is not buried in the insulation place should be derusted and painted once a year.

4. Product maintenance

Generally, the pump should be disassembled and repaired once a year, including cleaning and inspection. Cleaning is mainly to scrape off the scale on the inner and outer surfaces of the impeller, especially the scale in the flow passage of the impeller, because it has a great influence on the flow rate and efficiency of the pump. In addition, pay attention to cleaning the inner surface of the pump casing and the bearings. During the cleaning process, the various parts of the water pump should be carefully and carefully inspected to determine whether they need to be repaired or replaced, especially the impeller, sealing ring, bearing, packing and other parts should be checked.

5. Rust paint

When the water pump is in use, it is usually in a humid environment. Some frozen water pumps without thermal insulation treatment are covered by water (due to condensation) on the surface of the pump body during operation. For a long time, part of the surface of the pump body will be Rust, for this reason, the surface of the pump body of the chilled water pump that is not buried in the insulation place should be derusted and painted once a year.

6. Antifreeze water

When the pump is out of use, if the ambient temperature is lower than 0 °C, all the water in the pump and the water pipe should be drained to avoid the frost heave effect of the water from cracking the pump body and the water pipe.

a. The water inlet pipeline must be highly sealed, and there should be no water leakage or air leakage;

b. Regularly check the current value of the motor, which must not exceed the rated current of the motor;

c. There should be a special person to take care of the system when it is running, so as to avoid accidents;

d. If there is no abnormal noise increase in the motor bearing, there is no need to check and replace the bearing for two to three years.

1.If the pump is in use, once any fault is found, even a small fault cannot make it work. If the packing of the water pump shaft is found to be worn out, it should be added in time. If it continues to be used, the impeller will be damaged due to excessive energy consumption of the motor.

2.If the water pump vibrates violently during use, check the fault immediately to avoid damage to the water pump.

3. When the bottom valve of the water pump leaks, some people will fill the inlet pipe of the pump with dry soil and flush the bottom valve with water. This approach is really not advisable. Because when the dry soil is put into the water inlet pipe, the dry soil will enter the pump when the pump starts to work, which will damage the pump impeller and bearing, which shortens the service life of the pump. When the bottom valve leaks, it must be repaired. If it is very serious, it needs to be replaced with a new one.

4. Pay attention to maintenance after the water pump is used. When the water pump is used up, the water in the water pump should be drained, and then the water pipe should be removed and rinsed with clean water.

5. The tape on the water pump should be removed, then cleaned and dried. Be careful not to place the tape in a dark and humid area. The tape of the water pump should not be contaminated with oil, and no sticky substances should be applied to the tape.
