Double suction pump as an important form of centrifugal pump, because of its high head and large flow characteristics, widely used in engineering. This type pump impeller is actually made up by two back-to-back impeller, the impeller flow of water into a spiral. Double suction pump has the following characteristics: it is equivalent to two of the same diameter single suction impeller work at the same time, under the same outer diameter of impeller flow can increase one times; Level in the pump shell, inspection and maintenance is convenient, at the same time, import and export of double suction pump in the same direction and perpendicular to the pump shaft, to pump and in and out of the water pipe layout and installation; Double suction pump impeller structure symmetry, no axial force, run more smoothly.

SH type double suction centrifugal water pump suction and discharge nozzles are in pump axis line, horizontal axis and vertical position, opened in the pump shell, you do not need to remove the water when maintenance, discharge line and motor (or other prime mover) from the coupling to the direction of the pump and water pump are counterclockwise. If according to user's special order need to also can be changed to clockwise. The main parts of this type of pump are: the pump body, pump cover, impeller, shaft, double suction sealing ring, shaft sleeve, bearing, etc. In addition to the shaft material for quality carbon steel, the rest are made from cast iron. Studio, pump body and pump cover impeller in the system of in and out of the water flange with installation of vacuum table and pressure gauge tube screw holes, in and out of the water there are used for water pipe lower flange of the screw holes. Impeller with static balance test, with the collar on both sides of the shaft sleeve and nut, its axial position can be adjusted through sleeve nut, impeller of axial force USES the symmetrical arrangement of balance, there may be some residual axial force coaxial side bearing. Pump shaft by two single row radial ball bearing, bearing is installed in the pump body on both ends of the bearing body, butter lubrication, double suction sealing ring in order to reduce the number of water pump room water leakage back to the suction chamber. Pump through coupling by direct drive motor. The shaft seal for soft packing seal, seal cavity and cooling and lubrication in order to prevent the air leakage into the pump, there is water seal between the packing ring, pump work a small amount of high pressure water through the water seal tube into the water seal packing chamber.
