1. contain a thrust bearing, the rotor weight and axial force of the pump are assumed by it, the radial force of the second pump can not be well balanced, resulting in the running of the
pump often vibration, bearing wear fast, packing gland and packing easy to loose water leakage and other faults. axial flow deep well fire pump, on the top of the
original thrust bearing, adds a deep groove ball bearing as the radial positioning of the whole rotor part, so that the axial force and radial force are well balanced, the pump operation is
more stable and reliable.
2. axial flow deep well fire pump adopts advanced and reasonable bearing lubrication method -- constant oil level gauge for thin oil lubrication. The position of the
interface between the bearing body and the oil level gauge is determined by calculation. As long as the oil level indicator shows the oil level, it indicates that the oil level in the bearing
body is constant at ½ position of the thrust bearing ball, ensuring good lubrication effect of the bearing oil. The deep groove ball bearing on the upper part of the bearing body relies on
the rotation of the shaft neck (the shaft neck is designed with rectangular thread grooves and radial oil throwing holes) to hurl oil onto the rolling body of the upper bearing to achieve
splash lubrication.
3. Modular design of general components of axial flow deep well fire pump. According to the classification of the whole series of general parts, the main general parts of
nearly 80 specifications are: bearing parts, packing parts, guide bearing parts, shafting and intermediate pipe system. This greatly improves the general interchangeability and quality of
axial flow deep well fire pump parts, shortening the production cycle and reducing the product cost. At the same time, the original shaft system is optimized and the single shaft
length is no more than 2 meters, so that the guide bearings are distributed evenly and the vibration of the pump is reduced.
4 shaft flow deep well fire pump shaft coupling improvement design a use of sleeve type rigid coupling (including coupling sleeve and coupling). The inner hole of the
shaft sleeve adopts the structure of large and small head, which is convenient for disassembly. The shaft section matched with the coupling is chrome-plated on the surface to effectively
prevent bite. For the two adjacent shaft segments, a step is provided for the lower section and an elastic retaining ring is provided for the upper section. Fix the coupling sleeve to
prevent the coupling sleeve and shaft from falling off and causing damage to the pump.
5, axial flow of deep well pump shaft contact (coupling and coupling collar) is designed in each section the upper guide bearing frame, and guide bearing can be
installed from two directions, that can be used at the scene guide bearing frame bracket pad section section assembly, to avoid the influence for plant height is not enough long axis of
the fire pump installation and maintenance.
6. The sliding guide bearing ofaxial flow deep well fire pump adopts new PFC and saelon polymer material, which is far superior to the guide bearing material widely
used in the industry in terms of wear resistance, high temperature resistance and corrosion resistance, making the pump run more stable and reliable and have a longer service life.
Moreover, this kind of guide bearing soaked for 5 months hardly causes water swelling, which is very suitable for use under the condition that the fire pump will not run continuously for
a long time and greatly reduces the possibility of the pump shaft locking.
7, axial flow deep well fire pump rotor to do dynamic balance, the accuracy of the national standard level G6.3, than the industry general vertical pump to do static
balance requirements, pump vibration is very small.
8. axial flow deep well fire pump is changed from inner stop to outer stop. Special tooling (mandrel) and one-time clamping processing are used to
ensure the concentricity of upper and lower stops and avoid the eccentric of shaft and guide bearing caused by accumulated errors in processing.
9. axial flow deep well fire pump usually has inner tube (inner tube). Guide bearings need to be rinsed, lubricated and cooled with water; If the pump is the delivery
of clean water at room temperature, according to the user's requirements, remove the inner tube, dry start.
dry shaft shaft fire pump bearing components adopt double rolling bearing structure. Many manufacturers of long shaft fire pump, bearing components only
