A failure cause of syngas compressor
The failure of the syngas compressor is related to many factors, including unit vibration, seal leakage, etc. Usually, we think that the damage of the dry gas seal has little effect on the vibration of the syngas compressor unit, but the actual case tells us that the two influence each other.
In the chemical industry, the syngas compressor, as one of the core equipment, has always been the heart of chemical enterprises. Its stable operation is directly related to the stable production of chemical enterprises. Syngas compressor is one of the key units. Once the syngas compressor cannot run stably, the subsequent synthesis device cannot be produced normally, and the entire enterprise will face huge economic losses.
(1) Check the entire air system of the syngas compressor, disassemble and inspect the primary and secondary inlet filters to check whether the filter screen is damaged or blocked, and disassemble and inspect the fresh gas inlet separator and the circulating gas inlet separator. Check the syngas compressor's outlet wire mesh demister for blockage and damage, and eventually replace the damaged primary inlet filter.
(2) Disassemble and inspect the dry gas seals replaced by the front and rear overhauls of the syngas compressor. It is found that the two sets of dry gas seals at the non-driving end are all damaged. The first-stage dynamic and static ring of the dry gas seal replaced by the second overhaul has been crushed, which is also the reason why the syngas compressor unit has been vibrating greatly. Finally replaced the dry gas seals with two new sets of syngas compressors.
(3) The damaged rotor end thread of the syngas compressor cannot be repaired. The only way is to remove the thread as a whole, then re-process the thread, and make a new set of matching coupling installation disks, and then carry out the overall dynamic balance.
(4) Reprocess the parts where the bearing clearance of the syngas compressor is too small to ensure that the clearance is within the normal range.
It has been proved that the damage to the dry gas seal has a direct effect on the vibration of the syngas compressor unit.
Through the above analysis of the syngas compressor, hope it helps you.
