The DG600-240-05-18 guide plate is one of the core components of the DG600-240 boiler feed pump. It is designed for thermal power plants and cogeneration projects and is suitable for high-pressure boiler feed systems for 300MW units. The guide plate plays a key guiding and supporting role in the pump, ensuring the stable operation of the rotor assembly, while optimizing the flow efficiency of the medium and improving the overall pump efficiency.

​High-precision flow channel design: CFD flow field analysis technology is used to optimize the shape of the guide plate flow channel, reduce hydraulic losses, and improve the operating efficiency of the pump.

​Wear-resistant material: The guide plate is made of high-strength heat-resistant alloy steel. After heat treatment, it has excellent wear resistance, corrosion resistance and thermal deformation resistance, and is suitable for high temperature and high pressure conditions.

​Full core pulling compatibility: Matching with the cylindrical double shell structure of the DG series pump, it supports the maintenance design of the core pack being pulled out as a whole, which is convenient for quick maintenance and replacement, and reduces downtime.

 

Precision casting and CNC machining: The guide plate is formed by precision casting technology, with smooth flow channel surface and high dimensional accuracy, and fine machining with CNC machine tools to ensure perfect matching with the impeller and pump casing.

 

​Dynamic balance guarantee: The rotor assembly where the guide plate is located has been tested for high-precision dynamic balance, and the balance level has reached the industry-leading level, effectively reducing operating vibration and noise.

 

Applicable: Widely used in thermal power generating units and cogeneration projects of 300MW and above.

 

​Thermal deformation compensation: Combined with the pump body center support structure and the sliding pin system, the guide plate can still maintain stable centering under hot working conditions, reducing the impact of thermal stress.

​Long life design: The friction pair surface is quenched and has excellent wear resistance. Combined with mechanical sealing technology, the maintenance cycle is significantly extended.
