Reputation first, quality assurance, prompt delivery. Welcome friends to negotiate business. Multi-stage pump series or parallel operation Note: 1, multi-stage pumps work in tandem to improve lift, but pay attention to the pump intensity multiple pumps in series behind the pump. 2, pump parallel operation to increase the flow in the same piping system, the flow ratio will increase in parallel with the increase in the number of units is reduced pump. 3, the same performance as the best selection of centrifugal pumps in series or parallel. 4, either in series or in parallel, a single centrifugal pump operating point should aim falls within the high zone.

Multi-stage pump bearings are precision components, thus requiring the use of fairly cautious attitude that change is the use of high-performance bearings, if used improperly, it can not achieve the expected performance results, and easy to damage the bearing. First, to keep clean multistage pump bearing their surroundings even invisible dust into the bearing smile, will increase wear, vibration and noise of the bearing. Second, be careful when using the installation does not permit a strong punch, does not allow a direct hit with a hammer bearing, are not allowed to pass through the rolling pressure. Third, the use of appropriate, accurate installation tools to make use of special tools, try to avoid using fabric and staple fiber stuff like that. Fourth, to prevent corrosion of bearings multistage pumps with bare hands when handling bearings, to fully wash hands sweat, and coated with high-quality mineral oil before operation, during the rainy season and summer with particular attention to rust. The main types of self-balance multistage pump ZPD main types of self-balance multistage pump ZPD are: ZPD type, ZPDG type, ZPDF type, ZPDY type, ZPMD type. ZPD type: for delivery of solid particles, water temperature is below 80 ℃ or physical and chemical properties similar to liquid fresh water. It applies to mines, factories and urban water supply and drainage purposes. ZPDG type: for delivery of solid particles, the temperature of water or physical and chemical properties of -20 ℃ ~ 210 ℃ similar liquid water. For medium, low and high pressure water supply. ZPDF type: for conveying solid particles, corrosive liquid temperature is -20 ℃ ~ 105 ℃ of. Users can name the transmission medium, concentration, specific gravity, temperature and pump inlet pressure pump and other reasonable choice of material, seal the form, structure and determine pump motor power. ZPDY type: for delivery of solid particles, the temperature is -20 ℃ ~ 105 ℃, viscosity of less than 120 cSt oil and petroleum products. ZPMD Type: For delivery particle content ≤1.5%, granularity ≤1.3mm, mine medium temperature -20 ℃ ~ 80 ℃ of water and other similar sewage.
