涂層分子結(jié)構(gòu)的致密性,能隔絕空氣、水等介質(zhì)和水泵葉輪母材的接觸,減少電化學(xué)腐蝕及銹蝕。另外,高分子復(fù)合材料本質(zhì)是高分子聚合物,具有抗化學(xué)腐蝕性,可以提高泵的抗腐蝕性,能大大增強(qiáng)泵抵抗沖蝕和抗腐蝕能力。水環(huán)式真空泵是液環(huán)式真空泵中常見的一種。液環(huán)式真空泵是帶有多葉片的轉(zhuǎn)子偏心裝在泵殼內(nèi)。當(dāng)它旋轉(zhuǎn)時(shí),把液體拋向泵殼并形成與泵殼同心的液環(huán),液環(huán)同轉(zhuǎn)子葉片形成了容積周期變化的旋轉(zhuǎn)變?nèi)菡婵毡?。?dāng)工作液體為水時(shí),稱水環(huán)泵。水環(huán)泵主要用于粗真空、抽氣量大的工藝過程中。在化工、石油、輕工、及食品工業(yè)中得到了廣泛地應(yīng)用,如真空過濾、真空送料、真空濃縮、真空脫氣等。單級(jí)水環(huán)泵的極限壓力可達(dá)8~2×103Pa,雙級(jí)水環(huán)泵的極限壓力可達(dá)1×102Pa。
工作條件:1. The allowable working pressure is 2.5MPa, that is, the pump inlet pressure + pump lift ≤2.5MPa. According to the maximum pressure under the pump shell, the pump body and pump cover material using gray cast iron (1.6MPa), Ductile iron (2.0MPa), cast steel (2.5MPa). Please indicate the pressure of the pump or the material at the time of ordering.
2. Media: Water with a temperature of ≤105°C or other liquids of physicochemical properties similar to water (solid particles ≤80mg/L). Bearing 1, the use of grease lubrication of closed rolling bearings, simple maintenance, long running time, 2, equipped with a constant oil level oil cup, can also be used dilute oil lubrication;
3, the selection of imported (SKF, NSK, NTN) high-quality bearings, smooth operation, low noise, long service life. Compact structure and good stability.
S, SA series double suction medium open pump for the pump shell open structure, import and export are in the pump body, maintenance only need to hoist the pump cover, rotor parts can be removed for maintenance operations, without the need to disassemble the pipeline, very convenient. According to the need of electric motor (drive) can also be on the left side at the right end, convenient for on-site installation. The structure shortens the axial size of the rotor parts, the steel of the shaft is better, and the operation is more stable and reliable. Equipped with pump body seal ring, and impeller seal ring for optional parts. The sealing ring can be replaced after wear, reducing operating and maintenance costs.
