Product name: SH Double-suction Pump
Model: SH-single-stage double-suction pump
Application: SH-type irrigation pump main parts: pump, pump cover, impeller, shaft, double suction seal rings, bushings, bearings. In addition to the axis of materials for high-quality carbon steel, and its remaining multi-cast iron.
Product overview
SH-single-stage double-suction pump Structure Description:
SH-single-stage double-suction pump inlet and outlet are at the bottom of the pump axis, horizontal axis into a vertical position, the pump casing. In the open, without having to remove the water Maintenance, exhaust pipes and motor ( or other prime mover) as viewed from the direction of the coupling of the pump, water pumps are reverse-inch needle direction. As according to the special order can be changed to cis-inch needle rotation.
SH-type irrigation pump main parts: pump, pump cover, impeller, shaft, double suction seal rings, bushings, bearings. In addition to the axis of materials for high-quality carbon steel, and its remaining multi-cast iron.
Pump and pump cover constitute the studio impeller, in and out of the water flange system mounting vacuum gauge and pressure gauge tube screw out of the water formed with the lower flange drain pipe holes.
Impeller static balance check, with the sleeve nut and sides of the fixed sleeve, its axial position can be adjusted through the sleeve nut, the axial force of the impeller use its leaves are arranged symmetrically balanced, there may be some left The remaining axial force coaxial side of the bearing.
Shaft by two single row radial ball bearing, bearing mounted in bearings at both ends of the pump body, with grease lubrication, double suction seal ring to reduce the water pump pressurized water chamber to drain back to the suction chamber.
SH-single-stage double-suction pump parameters:
Flow rate (Q): 160-18000m3 / h
Head (H): 12-125m
SH-single-stage double suction pump Model significance:
6-SH-6-A
6- pump inlet diameter of 6 inches
SH- horizontal single-stage double-suction pump in the open water
6- pump specific speed of 1/10 rounding
A- impeller diameter cutting code
SH type in a pump assembly, disassembly and installation
Assembly and disassembly
1, the assembly of the rotor components: turn the impeller, shaft sleeve, sleeve nut, packing sleeve, packing rings, packing gland, retaining ring, bearing member mounted on the shaft, and put double suction seal rings, then install coupling.
2, the rotor assembly is mounted on the pump, adjust the axial position of the impeller of the halo to the middle on both sides of double suction seal ring to be fixed, the bearing body gland with fixing screws.
3, loading on the packing, put away the glossy paper pad open, cover the pump cover matter pintail pin, tighten the pump cover nut, finally installed Shangfen gland material. But do not be packing too tight, tight packing sleeve will heat, power consumption is large, but also not to cut too loose, too loose will make large liquid leakage, reducing pump efficiency.
After the assembly, the shaft is rotated by hand, no collision phenomenon, rotated relatively light evenly slippery, disassembly can be said assembly sequence contrary.
Installation
1. Check the pump and motor should be no damage.
2, pump installation height, plus hydraulic suction line losses, and its speed can not be greater than the allowable value of the sample suction on the vacuum height regulations. Base size should be consistent dimensions pump unit.
