Application of Thermal Transfer Oil Pump in Boiler Circulation System

In the fields of modern industrial production and energy supply, boilers, as an important thermal energy conversion device, are widely used in many industries such as power generation, heating, and chemical engineering. The efficient and stable operation of the boiler circulation system is crucial for ensuring the performance and safety of the boiler. In this complex system, the heat transfer oil pump plays an indispensable role, like a heart, providing continuous power to the entire circulatory system, ensuring effective heat transfer and utilization.

1、 Working principle and characteristics of thermal oil pump

Thermal oil pump is a type of pump equipment specifically designed for transporting high-temperature thermal oil. Its working principle is based on the action of centrifugal force. When the motor drives the pump shaft to rotate, the impeller also rotates at high speed. The blades in the impeller drive the heat transfer oil to be thrown from the center of the impeller to the edge of the impeller under the action of centrifugal force, thereby obtaining higher pressure and speed, and then being transported to the required place through the flow channel of the pump body.

The heat transfer oil pump has a series of unique characteristics, making it very suitable for application in boiler circulation systems. Firstly, it has excellent high-temperature resistance and can operate stably in high-temperature environments, typically withstanding temperatures up to 350 ℃ or even higher, which matches the high-temperature characteristics of heat transfer oil in boiler circulation systems. Secondly, the sealing performance of the heat transfer oil pump is excellent, which can effectively prevent the leakage of heat transfer oil, avoid safety hazards and energy waste caused by leakage. In addition, it also has high efficiency and reliability, and can work continuously and stably for a long time, meeting the requirements of uninterrupted operation of the boiler circulation system.

2、 The important role of heat transfer oil pump in boiler circulation system

1. Realize the circulation flow of thermal oil

In the boiler circulation system, heat transfer oil serves as a carrier of heat and needs to continuously circulate and flow between components such as the boiler, heat consuming equipment, and heat exchangers to achieve heat transfer and exchange. The heat transfer oil pump provides necessary power for the circulation of heat transfer oil, ensuring that the heat transfer oil can flow in the system according to the predetermined path and flow rate, so that the heat generated by the boiler can be timely and effectively transferred to the heating equipment, meeting the needs of production or life.

2. Maintain stable system pressure

The boiler circulation system needs to operate under a certain pressure to ensure the normal flow of heat transfer oil and heat transfer. The heat transfer oil pump can maintain the pressure stability of the system by adjusting its own flow rate and head. When the pressure in the system fluctuates, the heat transfer oil pump can automatically adjust its working state, increase or decrease the output flow rate, so as to maintain the system pressure within the set range and ensure the safe and stable operation of the system.

3. Improve the thermal efficiency of the system

The rational selection and optimized operation of heat transfer oil pumps are of great significance for improving the thermal efficiency of boiler circulation systems. By selecting the appropriate model and parameters of the heat transfer oil pump, the flow resistance of the heat transfer oil in the system can be minimized, reducing energy loss. At the same time, the efficient operation of the heat transfer oil pump can ensure that the circulation speed and flow rate of the heat transfer oil meet the requirements of the system, allowing heat to be fully transferred and utilized, improving the thermal efficiency of the boiler, and reducing energy consumption.

3、 Application example of heat transfer oil pump in boiler circulation system

Taking the steam boiler circulation system of a certain chemical enterprise as an example, the system uses a heat transfer oil pump as the circulating power equipment. In actual operation, the heat transfer oil pump extracts the heat transfer oil from the oil storage tank and sends it into the heating furnace tube of the boiler. After absorbing heat in the furnace tube, the temperature of the heat transfer oil increases, and then it is transported to various heat consuming equipment, such as reaction vessels, distillation towers, etc., to provide the required heat for the chemical production process. In thermal equipment, after releasing heat, the temperature of the heat transfer oil decreases and then flows back to the heat exchanger of the boiler through pipelines for heating, entering the next cycle again.

During this process, the heat transfer oil pump automatically adjusts its operating parameters based on changes in system pressure and temperature, ensuring stable circulation flow and pressure of the heat transfer oil. By reasonably configuring the number and model of heat transfer oil pumps, optimizing the pipeline layout and valve control of the system, the boiler circulation system of this chemical enterprise has achieved efficient and stable operation, not only meeting the heat demand of chemical production, but also improving energy utilization efficiency and reducing production costs.

4、 Maintenance and upkeep of thermal oil pump

In order to ensure the long-term stable operation of the heat transfer oil pump in the boiler circulation system, regular maintenance and upkeep are required. Firstly, it is necessary to regularly check the sealing performance of the heat transfer oil pump and replace worn or damaged seals in a timely manner to prevent heat transfer oil leakage. Secondly, it is necessary to regularly clean the filter screen and impeller of the heat transfer oil pump to remove impurities and dirt, and avoid blockages that may affect the performance of the pump. In addition, it is necessary to regularly check the insulation performance and lubrication of the motor to ensure its normal operation.

In summary, heat transfer oil pumps have important application value in boiler circulation systems. It provides strong support for the efficient and stable operation of boilers by achieving the circulation of heat transfer oil, maintaining system pressure stability, and improving system thermal efficiency. In practical applications, we should select and use heat transfer oil pumps reasonably according to the specific requirements of the boiler circulation system, and strengthen their maintenance and upkeep, in order to fully leverage their advantages and make greater contributions to industrial production and energy supply.
