Hydrosila Tandem Gear Pump NSH
1. Compared with the single-stage NSh pump, the NSh two-stage pump has larger dimensions, and the distance between the suction port and the discharge port and the welding plane is larger, resulting in changes in the structure of the suction pipeline and the discharge oil pipeline.
If you need to install a two-stage NSh pump, such as on MTZ50/5*2 tractors, the suction pipe and oil pressure pipe need to be replaced, when installing NSh32U pumps on MTZ80/82 tractors, the spline drive shaft must also be replaced, it comes from decommissioning MTZ50/52 tractors (usually not worn out). Double section gear pump
2. Two-stage gear pumps are designed to simultaneously pump working fluid into the hydraulic system (for example, into the tractor hydraulic system used to control the installed machine and the tractor power steering hydraulic system) through two independent flows.
3. Each section is an independent gear pump. Both sections are mounted in conjugate housings, driven by a single shaft, but have separate suction and discharge ducts.
These pumps are available for right or left hand rotation. The assembled pump is irreversible.
4. What are the advantages of two-stage pumps over single-stage pumps, two-stage pumps only need one driver to rotate the shaft; this type of pump takes up less space than two single-stage pumps, and the mass of a double-stage pump is less than double the mass of a single pump About 13%; the two-stage pump is more compact and easier to maintain.
The direction of rotation of the drive shaft of the double gear pump can be right or left, which has been agreed during the manufacturing process of the gear pump.
Double pumps must be driven via elastic couplings. Double gear pump NSh 32-10, NSh 10-10, NSh 14-10, NSh 32-10, NSh 32-32M4, NSh 50-50D3, NSh 112G-32UKF, NSh 100G-50UKF-3, 100G-32UKF-3 , NSh 100-50A-3, etc. according to the order, shaft diameter, flange size, cross-sectional volume, cross-sectional number, etc. The parameters, shaft and flange connection dimensions of single pump and sectional pump are the same. The drive shaft speed of a segmented pump is determined by the segment with the lowest speed. The maximum pressure for each segment is best agreed upon with the manufacturer. A group of NSh pumps and two pumps of different groups of gear pumps are connected in series.
