IRG vertical hot water make-up pump can also be called IRG vertical hot water circulation pump, IRG vertical boiler circulating pump, IRG vertical hot water booster pump, etc .; This series of products are vertical single stage Single suction heat pump, is based on the ISG-based research and development of a new generation of energy-saving, environmentally friendly vertical hot water centrifugal pump. Vertical hot water makeup pump structure and characteristics of what is it? IRG Vertical Hot Water Replenishment Pump Structure and Features I. IRG Vertical Hot Water Replenishment Pump Structure: The IRG vertical hot water recharging pump is mainly composed of impeller, shaft, pump housing, shaft seal and seal ring. Before the centrifugal pump is started, the pump housing must be filled with liquid. When the prime mover drives the pump shaft and the impeller to rotate, the liquid circulates with the impeller on the one hand and is thrown from the center of the impeller to the outer periphery under the action of centrifugal force on the one hand. Impellers obtain hydrostatic and hydrodynamic energy. When the liquid flows through the volute to the discharge port, some dynamic pressure can be converted into static pressure energy. When the liquid is thrown from the impeller, the center part of the impeller causes a low-pressure zone, which forms a pressure difference with the pressure of the suction liquid so that the liquid is continuously drawn in and discharged with a certain pressure. Second, the IRG vertical hot water make-up pump Features: 1. Stable operation: the absolute concentricity of the pump shaft and the impeller balance of static and dynamic, to ensure smooth operation, no vibration. 2 drip leakage: Carbide seals of different materials to ensure that there is no leakage of different media delivery. 3. Low noise: two low-noise bearings under the pump support, smooth operation, in addition to motor weak sound, the basic noise-free. 4. Failure rate is low: the structure is simple and reasonable, the key part of the world-class quality; supporting, machine trouble-free working time greatly improved. 5. Easy maintenance: replacement of seals, bearings, easy and convenient. 6 covers an area of ​​more provinces: the export can be left, right, up three directions, easy installation and installation of pipelines to save space.
