DINKONDA GLOBAL Power Plants Special IRG Series Rear Open Door Type 2950r/min Hot Water Circulation Pump, Single-stage Single Suction Cantilever Centrifugal Pump

Product Overview
The IRG type hot water circulation pump is a single-stage single suction cantilever centrifugal pump, specifically designed for transporting high-temperature hot water media, suitable for thermal heating, auxiliary systems in thermal power plants, and industrial heat exchange circulation systems. The pump adopts a mature hydraulic model with a rear open door structure. During maintenance, there is no need to disassemble the inlet and outlet water pipes. The rotor components can be directly extracted, which is suitable for long-term continuous operation of high-temperature media. The whole machine runs smoothly and has small thermal deformation. It is widely used in heating pipelines, boiler feedwater, heat exchange stations, chemical high-temperature water circulation and other occasions. The conveying medium is clean water without solid particles or high-temperature hot water with physical and chemical properties similar to clean water.

Structural Composition
1. Pump body: Made of heat-resistant cast iron/cast steel snail shell structure, with a horizontal inlet and a vertically upward outlet, the overall rigidity is strong and can withstand high-temperature medium thermal stress; The pump body flange meets the national standard for pressure vessel flanges and is resistant to high temperature and high pressure.

2. Impeller: Single suction closed impeller, high hydraulic efficiency, high dynamic balance accuracy, reduces high-speed operation vibration; The material is made of heat-resistant cast iron, suitable for hot water conditions, and the impeller is fixed to the pump shaft through a key.

3. Pump shaft and suspension components: cantilever structure, impeller suspended outside the bearing; The pump shaft is made of high-quality alloy steel quenched and tempered, which is resistant to high temperature and creep; The suspension body is equipped with rolling bearings, which are lubricated with grease and can withstand radial and residual axial forces. The structure is easy to disassemble and assemble.

4. Shaft seal components: can be configured with packing seals and high-temperature resistant mechanical seals, designed for hot water and high temperature conditions, effectively reducing hot water leakage and adapting to high-temperature vaporization environments of media.

5. End cover (pump cover): The rear end has a door opening structure. By loosening the connecting bolts, the impeller, shaft, and bearing can be pulled out for maintenance as a whole without disassembling the inlet and outlet pipelines, greatly reducing maintenance time.

6. Base: Steel common base, shared by pump and motor to ensure the coaxiality of the unit, reduce operating vibration, and facilitate on-site installation and alignment.

7. Drive mode: Elastic coupling direct drive matching motor.

Product Features
1. Rear door opening structure, easy maintenance: all rotor components can be extracted without dismantling the inlet and outlet water pipelines, with high maintenance and disassembly efficiency.

2. High temperature resistant design: The component materials are suitable for hot water conditions, fully considering thermal expansion, reducing the risk of high-temperature operation jamming, and can transport high-temperature hot water for a long time.

3. Smooth operation with low noise: The impeller undergoes precise dynamic balancing, and the bearing system structure is reliable, suitable for 24-hour uninterrupted continuous cycle operation.

4. Optional sealing scheme: Packing sealing is suitable for general working conditions; High temperature resistant mechanical seals have low leakage and are suitable for closed circulation systems.

5. Excellent hydraulic performance: efficient hydraulic model, wide operating range, low energy consumption, suitable for high flow and medium low head conditions in heating cycles.

6. Compact cantilever structure layout: The whole machine occupies a small area, and the layout of the heat exchange station, boiler room, and pump room is flexible.
