2、叶轮直接安装在电机的加长轴上,轴向尺寸短,结构紧凑,泵与电机轴承配置合理,能有效地平衡泵运转产生的径向和轴向负荷,从而保证了泵的运行平稳,振动小、噪音低。
1、吸入压力≤1.0MPa,或泵系统最高工作压力≤1.6MPa,即泵吸入口压力+泵扬程≤1.6MPa,泵静压试验压力为2.5MPa,订货时请注明系统工作压力。泵系统工作压力大于1.6MPa时应在订货时另行提出,以便在制造时泵的过流部分和联接部分采用铸钢材料。
1、供输送清水及物理化学性质类似于清水的其他液体之用,适用于工业和城市给排水、高层建筑增压送水、园林喷灌、消防增压、远距离输送、暖通制冷循环、浴室等冷暖水循环增压及设备配套,使用温度T<80℃。
Pipeline centrifugal pump selection of international excellent hydraulic model, in the general vertical pump on the basis of ingenious combination of design, at the same time according to the use of temperature, medium and other different in the pipeline centrifugal pump derived from the application of hot water, high temperature, corrosive chemical Pump, pump. The series of products with high efficiency, low noise, reliable performance and so on.
Features
1, the pump for the vertical structure, import and export caliber the same, and located in the same center line, like the valve can be installed in the same pipe, the appearance of compact and beautiful, small footprint, low construction, such as with a protective cover Can be placed outdoors.
2, the impeller is directly installed in the motor on the elongated shaft, axial size is short, compact, pump and motor bearing configuration is reasonable, can effectively balance the pump running radial and axial load, thus ensuring the pump running smoothly, Vibration is small, low noise.
3, the shaft seal with mechanical seal or mechanical seal combination, the use of imported titanium seal ring, medium-sized high-temperature mechanical seal and the use of carbide material, wear-resistant seal, can effectively extend the mechanical seal life.
4, easy installation and maintenance, no need to dismantle the pipe system, as long as the removal of the pump seat nut can extract all the rotor parts.
5, according to the use of requirements that flow and head of the need to use the pump string, parallel operation.
6, according to the requirements of the pipeline layout using the vertical and horizontal installation of the pump.
Working conditions
1, the suction pressure ≤ 1.0MPa, or pump system maximum working pressure ≤ 1.6MPa, that is pump inlet pressure + pump head ≤ 1.6MPa, pump static pressure test pressure of 2.5MPa, please specify the system when the work pressure The Pump system working pressure greater than 1.6MPa should be made in the order, so that when the pump part of the pump and the connection part of the use of cast steel materials.
2, ambient temperature <40 ℃, relative humidity <95%.
3, the volume of solid particles in the transport medium does not exceed 0.1% of the volume per unit volume, particle size <0.2mm.
Note: If the use of media with a small particle, please specify when ordering, so that the German Thomas Group wear-resistant mechanical seal.
The main purpose
1, for the delivery of water and physical and chemical properties similar to other liquids used in water, for industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation, fire booster, long-distance transport, HVAC refrigeration, Heating and water cycle pressurization and equipment, the use of temperature T <80 ℃.
2, applicable to: energy, metallurgy, chemical, textile, paper, and hotels and other high-temperature hot water boiler cycle and the city heating system circulation pump, the use of temperature T <120 ℃.
3, for the transport of non-solid particles, corrosive, viscosity similar to the liquid water, for petroleum, chemical, metallurgical power, paper, food and synthetic fiber and other departments, the use of temperature -20 ℃ ~ +120 ℃.
4, for the delivery of gasoline, kerosene, diesel and other petroleum products, the transmission medium temperature is -20 ℃ ~ +120 ℃.
