Water-cooled low-noise pump structure
Water-cooled low-noise pump structure I. Product Overview SG-type water-cooled low noise centrifugal pump is a new generation of products formed on the basis of direct-connected pipeline pump supporting the water-cooled motor developed by our company. It not only has the smooth operation of SG-type pipeline pump, simple structure, easy maintenance, covers an area of ​​province and other characteristics, and the noise is lower. The pump meets GB / T5657-1994 "centrifugal pump technical conditions (â…¢)" standard. For conveying water or other liquids with physical and chemical properties similar to water. ã€Features】 1, energy-efficient: CFD CFD, analyze and calculate the pump pressure distribution and velocity distribution, optimize the pump flow channel design, to ensure that the pump has an efficient hydraulic form Line, increased pump efficiency. 2, low noise: As a result of water-cooled motor, the motor side of the fan has been canceled, SG pump noise than the average ordinary pipe pump 3 to 5%. 3, self-cooling structure: Cooling water can not only cool the motor housing, but also cooling the motor up and down bearings, not only improve the bearing work environment, improve the bearing life, but also due to full motor cooling and improve motor efficiency. 4, maintenance-free structure: water-cooled motor bearings with closed bearings, eliminating the worries of the daily maintenance of bearings. 5, long service life: Axle material selection of 2Cr13 martensitic stainless steel, to avoid shaft corrosion caused by shaft seal failure or the need to replace the shaft concerns. 6, reliable life: The mechanical seal base generally use rubber bellows structure, the traditional mechanical seal on the shaft seal from the O-ring seal to the two pieces of rubber seal to improve the sealing effect. 7, outdoor use: high degree of protection, can be used outdoors. Third, the working conditions Flow: 2 ~ 1400 m3 / h Head: 5 ~ 80 m Medium temperature: <+80 ℃ Ambient temperature: ≤ +40 ℃
