PN series of land and sea horizontal sand pumping pump is designed with reference to the theory of two-phase flow of impurities pump, divided into: 250PN-30,250PN-35,250PN-40,350PN-24,350PN-35,350PN-45,400PN -22 type, the pump test and industrial operation test, with high hydraulic efficiency, good wear resistance characteristics. Stable when delivering media containing solid particles. The pump is suitable for inland river dredging, coastal embankment construction, and coal mines, mines, power plants and other enterprises conveying solids containing slurry, mud pump transmission medium concentration of up to 40%, medium particles up to 50 mm . In recent years, the Yellow River basin, Shanghai, Zhejiang, Tianjin, Tangshan and other places are widely used in silt pumping silt, blowing sand boat and land on the long-distance transport of sediment pressure. Structure Features PN series of pumping sand pump mainly by the pump, impeller, guard, pump cover, bracket and bearing components and other components. Pump body, impeller, guard material can be gray cast iron, wear-resistant alloy, and non-metallic wear-resistant materials, users can order according to the use of choice. Pump shaft seal packing seal, and in the packing chamber to join the high-pressure flush water, better ensure the normal operation of the pump steering pump from the inlet as counterclockwise, from the inlet to see the pump outlet in the horizontal direction of the right, As the site needs outlet can be adjusted in 360 degrees. Pumping sand pump fixed at the job site, the submersible pumping sand pump should first check the prime mover spindle and pump spindle in the same axis, if different axis should be made for precise adjustment. Pump inlet and outlet piping should be bearing support, to avoid the pipeline gravity applied to the pump body. Pipeline installation should be imported from the pump flange outward, and immediately make the support positioning. Suction pumping pump work must be filled with high pressure water chamber to protect the seal seal components. The main pump should not be closed during normal work of high pressure water pump. Water pressure should be greater than pumping pressure pumping work. Stuffing chamber components wear quickly without high pressure water protection. Suction stroke in the pump performance table refers to the anti-cavitation characteristics of the pump under normal temperature and water conditions. In the process of pumping sediment should be as far as possible to pump the inlet pressure is positive pressure. Sediment contains large solid particles when the pump flow head will also be affected, the media should be considered when selecting media. Change the impeller, liner and other wearing parts should be adjusted between the impeller and the front and rear liner, impeller and liner axial clearance size of the pump performance and service life have a greater impact. Please timely and appropriate bearing parts filling grease. Abnormal vibration pump at work, noise and bearing temperature is too high, should stop checking. Sediment pump body with internal and external double-layer metal structure, the pump shell is vertically open, the outlet position by 45-degree rotation of the shaft seal installed according to different conditions choose the appropriate way is divided into: Side wheel shaft seal, packing shaft seal and Mechanical seal with closed impeller, good wear resistance, high pump efficiency by adjusting the number of blades and impeller diameter delivery containing a small amount of larger particles of the mixture. Suitable for extracting loose, collapsible silt, fine sand, sand, coarse sand, adapted to pumping sand, mining, pumping tailing slurry, pumping silt, pumping sea sand, clearing the port. It can intermittently extract the largest amount of grit slurry within 120mm and can reach 60% of the solidified volume, which can be reclaimed from the sea, river sand to be extracted, sand pumping along the sea, iron ore sand and gold sands. The industrial and mining enterprises extract tailings slurry, Pumping from the sand far away from the pump, etc. The pump is a double pump shell structure, easy to replace parts, flow components using high wear Cr26 alloy material, long service life, using a combination of impeller and packing seal, convenient and durable, If you add red filling water better.
