產品概述：Product overview:
DG型多級離心泵具有效率高、性能范圍廣、運行安全平穩(wěn)、噪音低、壽命長、安裝維修方便等特點。供輸送清水或物理化學性質類似于水的其它液體。也可以通過改變泵過流部件材質、密封形式和增加冷卻系統(tǒng)用于輸送熱水、油類、腐蝕性或含磨粒的介質。
本型泵是單殼體節(jié)段式多級離心泵。其吸入口和吐出口均垂直向上。前段、中段和后段用穿杠聯接成一體，各段之間靜止結合面主要靠金屬面密封外，并沒有O型膠圈作為輔助密封。DG型高壓泵的吸入段、中段、吐出段采用鍛件。
DG multistage centrifugal pump is characterized by high efficiency, wide performance range, safe and stable operation, low noise, long service life, convenient installation and maintenance, etc. It is used to transport clear water or other liquids with physical and chemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material and sealing form of the flow passage parts of the pump and adding a cooling system.
This type of pump is a single shell segmental multi-stage centrifugal pump. The suction inlet and discharge outlet are vertically upward. The front section, the middle section and the rear section are connected as a whole by a threaded rod. The static joint surface between the sections is mainly sealed by the metal surface, and there is no O-ring as the auxiliary seal. Forgings are used for suction section, middle section and discharge section of DG type high-pressure pump.
