Hot water circulating pump is the use of CAD modular structure design, advanced model of high efficiency, simple structure will be repaired, safe and reliable long life, energy saving and environmental protection, are widely used in metallurgy, power plants, rubber tires , Chemical industry, textile, large-scale construction facilities and other systems of hot water or other organic heat exchange medium (liquid) delivery and circulation. On the hot water circulation pump eight performance characteristics Hot water circulation pump performance characteristics are as follows: 1, open the door structure and the extension of the intermediate coupling design, the overhaul of the impeller, mechanical seal, without dismantling the pump body, motor and import and export The pipeline can be carried out, is very simple and convenient; 2, the hot water circulating pump pump shaft structure optimization design to improve the overall stiffness of the pump shaft, thereby reducing the deflection and reducing pump operation vibration and noise; 3, Hot water circulating pump according to different media, the choice of standard mechanical seal or metal bellows mechanical seal; 4, mechanical seal cooling chamber volume larger than similar products, cooling effect, extended machine seal life; 5, And a hot water circulation pump inlet between the throttling bypass pipe, so that the seal cavity of the high-pressure medium flow to the pump inlet, so that the sealing medium circulation chamber, which reduces the seal chamber temperature and pressure is conducive to mechanical seal Service life, but also improve the cavitation performance of the hot water circulation pump inlet; 6, the mechanical seal gland additional cooling water chamber, the quench ring can be quenched by cooling water, when the medium temperature exceeds 170 , Optional self-contained threaded pump mechanical seal, with a heat exchanger, with the cooling of the pump medium flush seal face, greatly extending the life of the machine seal; 7, the choice of reinforced bearings and an increase of lubrication and The volume of lubricating oil cooling cavity prolongs the service life of bearing. 8. The latest three-dimensional impeller hydraulic design has high efficiency and good anti-cavitation performance and can be used as condensate pump.
