污泥輸送泵@尋烏125ZJE-II污泥輸送泵哪個廠家好

在水泵工作過程中，泵內流動的水受到其與流道和泵葉輪表面的摩擦以及水本身粘度的影響，泵所消耗的能量主要用于抵抗水表面的流動摩擦力及渦流阻力。水在流動過程中所消耗的能量(水頭損失)就是用來克服內摩擦力和水與設備界面的摩擦力。如果泵、葉輪表面光滑(這種表面稱為水力光滑表面)表面阻力較小。消耗能量就小，在水泵過流面和葉輪上噴涂高分子復合材料，使其表面形成水力光滑表面，超光滑表面涂層表面光潔度是經過拋光后不銹鋼的20倍，這種極光滑的表面減少了泵內流體的分層，從而減少泵內部紊流，降低了泵內的容積損失和水力損失，降低了電耗。達到降低水流阻力損失的目的，從而提高水泵的水力效率，同時在一定程度上也可提高機械效率和容積效率。涂層分子結構的致密性，能隔絕空氣、水等介質和水泵葉輪母材的接觸，最大程度減少電化學腐蝕及銹蝕。另外，高分子復合材料本質是高分子聚合物，具有抗化學腐蝕性，可以提高泵的抗腐蝕性，能大大增強泵抵抗沖蝕和抗腐蝕能力。

水環泵也有其缺點：(1)效率低，一般在30%左右，較好的可達50%。(2)真空度低。這不僅是因為受到結構上的限制，更重要的是受工作液飽和蒸氣壓的限制。

二、創新技術特點

1. Unique sealing device using negative pressure technology plus combined sealing device, in the increasing pressure and flow is gradually reduced, sealing components do not bear pressure, especially in the late press period due to the pump under large pressure, its innovative seal structure design, to ensure that the shaft seal basically achieved no leakage.
2. Structural design of two-stage impeller
The pump adopts the double main pump body, the structure design of the double main impeller, completely solves the requirement that the single pump leaf wheel pump has too much vibration and noise, flat performance curve, narrow leaf rotation path, poor performance and so on, and the change of resistance when the filter press feed is very suitable for the requirements of high flow and low pressure feeding and small flow rate.
3. Double impeller pump than single leaf wheel pump anti-wear resistance is better
Because the double impeller pump at the lower impeller outlet line speed to obtain higher pump outlet pressure to overcome the single-leaf wheel pump in order to increase the pressure and increase the impeller line speed, resulting in impeller, pump shell wear increased shortcomings, effectively improve the life of water pump and other overcurrent components.
4. Wide range of applications
The product can be made of cast steel, high chromium cast iron (corrosion-resistant wear-resistant materials), stainless steel and other materials, can be adapted to different media needs, the user selection of a wider range.
5. Adjustable gap between impeller and pump wall
Unique bearing box design, users in the regular time after use, due to wear caused by pressure drop, can be adjusted impeller and pump wall gap to continue to ensure the high pressure of the pump, improve the service life of the pump, extend the overhaul cycle, overcome the traditional single-leaf wheel pressure filter pump due to the wear pressure drop fast, often replace the impeller service life is short
