Changsha Pentium pump developed a new energy-saving products - ZPD self-balancing multi-stage pump (Figure)

Complying with the Chinese government's "Eleventh Five-Year" proposed energy-saving emission reduction requirements, Changsha pump manufacturers Pentium Pump Organization production, research and development, quality, technology and other departments after more than three years developed a new generation of multistage pump energy efficient products ZPD Efficient self-balancing multi-stage pump. The Pentium pump research and development department director Liu Zhihong introduced the pump's largest structural feature is the use of the forward and reverse 2 sets of impeller, can automatically eliminate the axial force; use of non-equilibrium device to reduce friction loss and balance of return loss, year-on-year ordinary multilevel Pump efficiency increases significantly by 6-15%. ZPD self-balancing multi-stage pump is a new milestone in the history of multi-stage pumps. ZPD self-balancing multi-stage pump with energy-efficient and many other highlights and technical advantages ZPD self-balancing multi-stage pump with high efficiency wide, wide range of performance, cavitation performance, safe and stable operation, low noise, less wearing parts, installation and maintenance Convenient and so on. Reliability is greatly improved, trouble-free operation time is more than 3 times the ordinary pump, user maintenance costs greatly reduced, thereby reducing pump life cycle costs. High-pressure self-balancing segmented centrifugal pump structure of the traditional multistage centrifugal pump has been innovative, canceled the multistage centrifugal pump axial force balance mechanism is the use of balance disc or balance drum structure D, DG-type multistage centrifugal Pump the best alternative. Because no unbalanced device, that is, unbalanced disc friction loss and no balance of return loss, so the pump efficiency than the same class of multi-stage pump to improve 6-15%, at the same time completely solve the balance device failure caused by balance plate and balance plate Wear and tear or rotor bite and other failures, greatly extending the life of the pump. Years of operation proved that the performance of the product reached the international advanced level of similar products. The main structure of ZPD self-balancing multi-stage pump ZPD self-balancing multi-stage pump is a single-stage or double-suction horizontal multistage centrifugal horizontal multistage centrifugal pump. The suction port of the pump can be vertical upward or horizontal and the discharge port can be vertically arranged upward. Mainly include: water inlet section, middle section, outlet section, secondary inlet section, positive guide vane, anti-guide vane, positive impeller, anti-impeller, shaft, throttling, pressure reducing device, stop sleeve, bearing body, transition pipe, etc. Parts; the middle by the high-strength bolts through the bar and out of the water connection, the pump inlet, middle, the seal between the water surface are made of molybdenum disulfide grease metal surface hard seal; rotor mounted on the shaft The front impeller, throttling decompression device, anti-impeller, sleeve, bearing sleeve and other components; bearings using "solid - swim" dry oil lubrication structure, the drive side cylindrical roller bearings, the end of the angular contact ball bearings ; Pump studio by the water section, the middle section, the water section, the secondary water section, is the guide vane, anti-guide vane, transition tube, etc .; between the rotor part and the fixed part with a seal ring, guide vane sets Seal, when the seal ring and guide vane sleeve wear has affected the performance of the pump should be promptly replaced; shaft seal in the form of mechanical seal and packing seal two. Pump packing used to seal the location of the filler ring placed correctly, the degree of tightness of the filler must be appropriate to the liquid can be a drop of ooze appropriate. Pump seals installed in a variety of sealed chamber, the cavity must pass a certain pressure of water, water seal, water cooling and water lubrication. In the shaft seal is equipped with a replaceable sleeve to protect the pump shaft. Unique structural strength design allows the pump single-stage lift of 1.5Mpa (150m), the outlet pressure up to 18Mpa (total head of 1800m), and make the core components of bearings and rotors from temperature changes, with excellent Thermal shock resistance. ZPD self-balancing multi-stage pump special cartridge mechanical seal due to no axial movement, completely overcome the old multistage pump axial movement static and dynamic ring grinding surface wear failure due to poor contact. In actual operation, did not leak drip. Pump factory in Changsha Pentium pump more than 20 years experience in production of multi-stage pump Changsha Pump Factory Pentium pump has been producing multi-stage pump to provide users with quality products, perfect service. The introduction of this new product and a strong guarantee of smooth operation of new products once again proved that the pump manufacturers in Penang, Pentium Pump Company as a more than 20 years of professional multi-stage pump manufacturers can withstand the test of the market, let's wait and see! This reporter also collected since 2010, ZPD self-balancing multi-stage pump one after another application to the coal, chemical and other industries without fault reports. Technology is the primary productive force, once again in the pump factory in Changsha, Pentium pump body has been confirmed.
