To repair the bearing chamber, also can such

A coarse sieve feed pump ( Sulzer) Bearing chamber wear, because the pump is critical in the machine operation, enterprise pays attention. Pump shaft speed 1450 r/min, the field measurement of wear 0. 1 mm or so, affect the normal bearing assembly. Pump shell value higher, tens of thousands of yuan, if the scrap change, after the capital, adopted a new technology - — Carbon nano polymer technology.     Carbon nanotubes polymer technology is a, which is different from traditional in the subsequent consumption, the operation process of equipment, maintenance cycle and so on have more progress, and is a repair is completed online operation.     Needle wear on screen feed pump bearing chamber, the previous online process repair plan has the following categories: ( 1) The brush plating technology ( 2) Pitting, direct bearing assembly & emsp;   Low brush plating repair technology & emsp;   Its advantage is to be able to complete online repair, its defect is very obvious. The brush plating technology of brush plating coating by wear limit, ordinary brush plating coating brush plating thickness less than 0. 2mm。 When wear is greater than zero. 2 mm, the brush plating efficiency will be multiplied to land, and too thick brush plating, in the process of using brush plating easily shattered and use life is short. 2 - about the wear depth The status of the 3 mm, brush plating process cannot be completed online brush plating.     Low scutching point & emsp;   Play pitting repair technology is a kind of emergency measures, and wear very small place, only after repair of the bearing inner ring and shaft fit only for contacts, so in the operation process under the condition of large load, pitting susceptible to fatigue wear, use of life is short, can only be temporary emergency.     After thinking several bearing housing maintenance process, selection of carbon nano polymer, is due to the large level data itself felt good, good pressure resistance, abrasion resistance and have metal comprehensive mechanics performance of elastic deformation, etc, the other is to repair the details of technical guidance, for example, can online repair, machine repair, repair of high efficiency and no demand of equipment a large number of disassembly, eight hours - ordinary situations To complete the repair within 24 hours.
