Cooling Tower Water Pump Precautions During Runtime
Start:
1. The rotation direction of the pump should be clockwise from the drive end towards the pump;
2. Before the operation of the pump, it should be confirmed whether the rotation direction of the motor is correct and whether the pump rotates flexibly. The test time should be short to avoid dry grinding of the mechanical seal; Fully open the inlet gate valve and close the gate valve of the discharge pipeline;
3. Fill the pump with water or use a vacuum pump to draw water
4. Connect the power supply, gradually open the gate valve on the discharge pipeline when the pump reaches normal speed, and adjust the opening of the outlet gate valve to the desired working condition. Attention should be paid to adjusting the opening of the outlet gate valve and measuring the motor current of the pump to ensure that the motor operates within the rated current. Otherwise, it will cause the pump to operate at overload (i.e. high current operation) and cause the motor to burn out. The opening size of the outlet valve that is adjusted correctly is related to the working conditions of the pipeline.
Stop:
1. Gradually close the gate valve on the discharge pipeline and cut off the power supply.
If the ambient temperature is below 0 ℃, the water inside the pump should be drained to prevent the pump body from freezing and cracking.
3. If the pump is not used for a long time, it should be disassembled, oiled, packaged, and reported.
Operation:
1. The inlet pipeline must be filled with liquid, and the pump is prohibited from running for a long time in a cavitation state.
2. Regularly check the motor current value and ensure it does not exceed the rated current of the motor.
During driving and operation, it is necessary to pay attention to the instrument readings, bearing heating, shaft seal leakage, heating, vibration, and noise to ensure that they are normal. If any abnormal situations are found, they should be dealt with immediately.
3. The maximum bearing temperature shall not exceed 80 ℃, and the bearing temperature shall not exceed the ambient temperature by more than 40 ℃

Cooling Tower Water Pump Application
Cooling tower pumps are one of the core equipment for maintaining the normal operation of cooling tower systems. By driving the circulation of cooling water, they enable heat exchange and have extensive and crucial applications in numerous fields.
1. Cooling Tower Water Pump Application in Industrial Production
Cooling tower pumps play a vital role in industrial production. In chemical enterprises, a large number of chemical reactions generate heat. If the heat is not dissipated in a timely manner, it may affect the reaction process and even lead to safety accidents. Cooling tower pumps transport high - temperature cooling water from production equipment to cooling towers. After heat dissipation and cooling, the low - temperature cooling water is sent back to the equipment, forming an efficient circulating cooling system. For example, in the cracking units of petrochemical plants, cooling tower pumps operate continuously and stably, ensuring that the units run at appropriate temperatures, thereby improving production efficiency and product quality. In the steel - making process, the large amount of heat generated by equipment such as blast furnaces and converters also relies on cooling tower pumps to circulate cooling water, preventing equipment damage due to overheating and ensuring the continuity of steel production.
2. Cooling Tower Water Pump Application in Commercial Buildings
In the field of commercial buildings, cooling tower pumps serve as the "power heart" of central air - conditioning systems. In large shopping malls, office buildings, and hotels, central air - conditioning systems need to continuously adjust indoor temperatures to meet people's comfort requirements. Cooling tower pumps lift the high - temperature cooling water that has absorbed indoor heat to the top of the cooling tower. Through methods such as spraying and air convection, the water is cooled, and then the cooled water is pumped back to the air - conditioning units, providing a cold source for indoor refrigeration. In addition, some commercial buildings are equipped with ice - storage systems. During low - power - consumption periods, cooling tower pumps work with refrigeration equipment to store cold energy, which is then released during peak periods, achieving off - peak power consumption and reducing operating costs.
3. Cooling Tower Water Pump Application in the Energy Industry
Cooling tower pumps also play an important role in the energy industry. In thermal power plants, after steam drives turbines to generate electricity, it needs to be cooled and converted back into water for recycling. Cooling tower pumps transport the hot water cooled by high - temperature exhaust steam to the cooling tower for cooling, and then the cooled water returns to the boiler, forming a complete thermodynamic cycle system and improving energy utilization efficiency. In nuclear power plants, cooling tower pumps undertake the crucial task of cooling the reactor, ensuring the safe and stable operation of the reactor and preventing serious accidents such as nuclear leakage.
4. Cooling Tower Water Pump Application in Data Centers
In data centers, the large amount of heat generated by the operation of numerous servers needs to be dissipated in a timely manner. Cooling tower pumps, in conjunction with precision air - conditioning systems, circulate cooling water to the heat exchangers of server cabinets, removing heat and maintaining the normal operating temperature of the servers, thus ensuring the stable operation of the data center. Moreover, in industries with strict requirements for production environment temperatures, such as food processing and pharmaceuticals, cooling tower pumps create suitable temperature conditions for production processes through stable water circulation cooling, ensuring product quality and production safety.
Cooling tower pumps, with their stable water circulation driving capabilities, play a key role in multiple fields such as industry, commerce, and energy. They are important basic equipment for ensuring the normal operation of equipment and the comfort and stability of the environment in various industries.
