The installation and piping quality of the circulating pump F320V12A1C22R, as the heart of the EH oil system of the steam turbine, directly affects the reliability and stability of the entire system. This article will elaborate on the key factors that need to be considered during installation and piping to ensure the normal operation and maintenance of the turbine EH oil circulation pump.

Before installation, a detailed survey of the installation location should be conducted to ensure that the pump is easy to maintain and repair, while considering the impact of vibration and noise generated during pump operation on the surrounding environment. The foundation of the pump must be solid and stable, able to withstand the weight and vibration of the pump during operation. It is usually necessary to pour concrete foundation and reserve sufficient space for pump fixation and pipeline connection. Consider the environmental conditions required for pump operation, including temperature, humidity, dust prevention, corrosion prevention, etc., and take corresponding protective measures if necessary.

During the installation process, carefully calibrate the levelness of the pump using a spirit level to ensure the coaxiality between the pump shaft and the drive motor shaft, avoiding additional vibration and wear caused by misalignment. Use appropriate fasteners to firmly secure the pump to the foundation, while ensuring a smooth connection between the pump and motor without stress transmission. Choose appropriate pipeline materials and sizes, connect the inlet and outlet of the pump, pay attention to the support of the pipeline and the use of compensators, to avoid additional tension or pressure on the pump body caused by the pipeline.

Before connecting the pump, the pipeline must be thoroughly cleaned to remove any possible residual impurities and prevent damage from entering the pump body. Considering the effects of thermal expansion, contraction, and vibration, expansion joints should be installed at appropriate positions on the pipeline, and supports and hangers should be arranged reasonably to ensure that the thermal stress of the pipeline will not be transmitted to the pump body. Install a filter at the inlet of the pump to protect it from impurities; Install a check valve at the outlet to prevent oil backflow and protect the safety of the pump. Ensure that the pipeline has a certain slope, which is conducive to the flow of oil and avoids the accumulation of oil in the pipeline, especially in low-temperature environments.

After installation, a series of tests and debugging are required. Before filling the system with oil, conduct an airtightness test to check for any leaks at all connections. According to the manufacturer’s manual, fill the system with oil and thoroughly eliminate air to avoid cavitation that may damage the pump’s performance. During the initial operation, closely monitor the vibration, temperature, pressure and other parameters of the pump, adjust the system settings as needed, and ensure the stable operation of the pump.

The correct installation and precise piping of the turbine EH oil circulation pump F320V12A1C22R are the cornerstone to ensure the stable operation of the turbine control and protection system. By following the above key considerations, it is possible to minimize the occurrence of faults, extend the service life of pumps, and provide a solid guarantee for the efficient operation of thermal power plants.
