Regeneration pump HQ37.13Z usually adopts a relatively compact and sturdy structural design to adapt to the complex working environment of power plant. It is mainly composed of motor, pump body, impeller, mechanical seal and various connecting parts. As the power source, the motor provides stable mechanical energy for the operation of the pump. The pump body is made of high-strength corrosion-resistant materials, which can not only withstand a certain pressure, but also effectively resist the corrosion that may be caused by fire-resistant oil. The impeller is a key component for the pump to achieve liquid transportation. Its design fully considers the adaptability to the characteristics of fire-resistant oil. Through the centrifugal force generated by high-speed rotation, the fire-resistant oil is sucked from the suction port and discharged from the discharge port after pressurization.

From the working principle, the regeneration pump HQ37.13Z is a kind of centrifugal pump. When the motor drives the impeller to rotate at high speed, a low-pressure area is formed at the center of the impeller. Under the action of external atmospheric pressure or system pressure, the fire-resistant oil is continuously sucked into the center of the impeller. Under the action of centrifugal force, the fire-resistant oil entering the impeller is thrown to the edge of the impeller, and the speed and pressure are increased. Then it is transported to the subsequent processing link of the regeneration device along the flow channel of the pump body. In the whole process, the mechanical seal plays a vital role. It effectively prevents the leakage of fire-resistant oil and ensures the normal operation of the pump and the sealing of the system.

Performance

1. Flow and head: The flow parameters of the HQ37.13Z regeneration pump have been carefully designed to meet the actual needs of the regeneration device of the power plant turbine fire-resistant oil system. It can usually reach a flow output of tens of cubic meters per hour, ensuring that the fire-resistant oil can be circulated in the regeneration device at a suitable speed. In terms of head, the pump has sufficient pressure lifting capacity, which can overcome the system pipeline resistance and the pressure requirements of the subsequent processing equipment, and smoothly transport the fire-resistant oil to various required parts to ensure the continuity of the regeneration process.

2. Working pressure and temperature range: Considering the working characteristics of the fire-resistant oil system, the HQ37.13Z regeneration pump can withstand higher working pressures. Generally, it can operate stably under a pressure environment of tens of MPa and adapt to the pressure fluctuations that may occur in the fire-resistant oil system. In terms of temperature adaptability, it can work normally within a certain temperature range. Whether in the low temperature environment in winter or the high temperature environment caused by equipment operation in summer, it can ensure that the performance of the pump is not significantly affected, ensuring the stable operation of the fire-resistant oil system.

3. Efficiency and stability: The design of this pump focuses on improving efficiency. By optimizing the impeller shape and flow channel design, it improves the energy conversion efficiency and reduces energy consumption. At the same time, its stability is excellent. During long-term continuous operation, it can maintain a stable output of flow and pressure, reduce fluctuations, and provide a solid guarantee for the reliable operation of the fire-resistant oil system.

Role in the turbine fire-resistant oil system

1. Purify fire-resistant oil: During the long-term operation of the turbine system, fire-resistant oil will be affected by oxidation, pollution and other factors, resulting in a decrease in oil quality. The regeneration pump HQ37.13Z extracts fire-resistant oil from the system and sends it to the filter, adsorber and other equipment of the regeneration device to remove pollutants such as moisture, particulate impurities, and acidic substances in the oil, restore the cleanliness and physical and chemical properties of the fire-resistant oil, extend the service life of the fire-resistant oil, and reduce the risk of equipment failure caused by oil quality problems.

2. Maintain system pressure balance: It continuously returns the treated fire-resistant oil to the system to replenish the oil loss caused by system leakage, equipment operation, etc., and maintain the pressure stability of the fire-resistant oil system. Stable pressure is essential for the normal operation of the turbine’s speed control system, security system, etc., and can ensure that the turbine can accurately control the steam intake under various working conditions and ensure the safe and stable operation of the unit.

3. Promote fire-resistant oil circulation: By continuously circulating the fire-resistant oil, the regeneration pump HQ37.13Z keeps the fire-resistant oil in the entire system with good fluidity, avoiding stagnation and deterioration of the oil in local areas. Good oil circulation helps to evenly disperse the heat generated by the system operation, prevent damage to the equipment due to excessive oil temperature, and also make additives and other ingredients evenly distributed in the oil, so as to better play the performance of the fire-resistant oil.

Maintenance points

1. Regular inspection and maintenance: Regularly check the oil level of the pump to ensure sufficient lubrication; check the wear of the mechanical seal and replace it in time if necessary; clean the pump body, impeller and other components to remove attached impurities. At the same time, the flow rate, pressure and other parameters of the pump should be checked regularly to ensure that its performance meets the requirements.

2. Monitor the operating status: By installing vibration sensors, pressure sensors and other equipment, the operating status of the regeneration pump can be monitored in real time. Once abnormal noise, vibration, pressure fluctuations and other conditions are found, stop the machine for inspection in time, find out the cause of the failure and repair it.

3. Replace wearing parts: According to the use of the pump and the manufacturer’s recommendations, mechanical seals, bearings, gaskets and other wearing parts should be replaced regularly to prevent failures and ensure the long-term stable operation of the pump. When replacing wearing parts, reliable accessories should be selected and the installation requirements should be strictly followed.

The regeneration pump HQ37.13Z has become an indispensable part of the anti-fuel system of the steam turbine of the power plant due to its key performance and role. Understanding its structure, performance, role and maintenance points is of great significance to ensure the safe and stable operation of the power plant and improve the power generation efficiency.
