Product name: XS single-stage double-suction centrifugal pump
General description:
XS: new split-center pump
250: pump outlet filling diameter (mm)
450: standard impeller diameter (mm)
A: change in pump impeller outer diameter (not indicated when the maximum diameter is reached)
L: vertical mount
R: heating water
J: change in pump speed (not indicated when the original speed is maintained)
XS pump is a new generation of high-efficiency and energy-saving single-stage double-suction split-center centrifugal pump, mainly suitable for water plants, air conditioning circulating water, heating pipe network systems, building water supply, irrigation, drainage pump stations, power plants, industrial water supply systems, fire protection systems, shipbuilding industry, mine water supply and drainage and other occasions for conveying liquids. It is a comprehensive replacement product for SH, S, SA, SLA, SAP split-center double-suction pumps.
Structural features
1) The support spacing at both ends of the pump is short, the pump runs stably, the vibration and noise are small, and the pump can be properly increased in speed, so that the pump has a wider range of adaptability.
2) The water inlet and outlet are in the same straight line, making the pipeline layout simple, convenient and beautiful.
3) The same rotor can run in reverse, reducing the risk of water hammer causing damage to the water pump.
4) The unique high-temperature design, the water pump adopts intermediate support, thickened pump body, seal cooling, bearing thin oil lubrication, etc., so that the water pump can be used in operating occasions up to 200°C, especially suitable for heating pipe network use requirements.
5) The pump body can be installed vertically or horizontally according to the changes in the use conditions, and the seal can be mechanical seal or packing seal.
6) The appearance of the water pump uses industrial design, with clear lines, in line with modern aesthetics.
7) The selection (adoption) of excellent hydraulic models makes the pump efficiency 2-3% higher than that of the same type of pumps, greatly reducing the operating cost of the pump.
8) The required cavitation margin is reduced by 1-3 meters, thereby reducing civil engineering investment and extending the service life.
9) Imported bearings are selected, and the parts material can be selected according to the user's application requirements, so that the pump can adapt to various on-site operating conditions, greatly reducing the maintenance cost.
10) No adjustment of mechanical seals, replacement of mechanical seals becomes an easy and simple task.
11) The assembly is designed with elastic prestressing, and the rotor parts can be assembled and disassembled easily and quickly.
12) No need to adjust various clearances during assembly.

SH type double suction water centrifugal pump suction inlet and outlet are under the pump axis, the horizontal direction and the axis into a vertical position, the pump shell open, maintenance without disassembling the water, discharge pipe and motor (or other prime mover) from the coupling to the pump direction, the pump are rotating counterclockwise direction. If according to the user's special order needs can also be changed to clockwise rotation. The main parts of this type of pump are: pump body, pump cover, impeller, shaft, double suction seal ring, shaft sleeve, bearing and so on. In addition to the material of the shaft is high-quality carbon steel, the rest are mostly made of cast iron. The pump body and the pump cover form the impeller workshop, and the inlet and outlet water flange is provided with a pipe screw hole for installing a vacuum gauge and a pressure gauge, and the lower part of the inlet and outlet water flange is provided with a pipe screw hole for discharging water. After static balance check, the impeller is fixed by the sleeve and the sleeve nuts on both sides, and its axial position can be adjusted by the sleeve nuts. The axial force of the impeller is balanced by the symmetrical arrangement of its blades, and there may be some remaining axial force borne by the bearings at the coaxial end. The pump shaft is supported by two single-row centripetal ball bearings, which are installed in the bearing body at both ends of the pump body and lubricated with butter. The double suction sealing ring is used to reduce the water leakage of the water pump pressure chamber back to the suction chamber. The pump is driven directly by the motor through a coupling. The shaft seal is a soft packing seal, in order to cool and lubricate the sealing cavity and prevent air from leaking into the pump, there is a water seal ring between the packing, and a small amount of high pressure water flows into the packing cavity through the water seal tube when the pump is working.
