Compressor head bearing overhaul decision tips
Author: 志和      Release Date:2014/4/19      View Count:1749
 

With the continuous operation of rotary air compressor, host each bearing will wear it is inevitable. The bearing wear always easily lead screw to produce axial and radialdisplacement increases, this change will make the gap between the screw and thescrew, and the host shell and a rear face of change. These changes of the gap is normal to allow in the period of bearing life, increase is normal the resulting air compressor gas attenuation load and main motor.

With the overhaul period running time of air compressor is close to the host, the hostbearing life gradually enter the maximum permissible limit. The screw axial and radialrunout and gradually into the maximum permissible value, the change will make thegap between the screw, screw and screw with the host shell and a rear face ofchange. The host operation is safe, but also have to consider and plan for overhaul to host. Because once the running time of air compressor unit over the overhaul period,bearing wear and the host with the gap will reach the limit allows the host to the technical conditions of the value, the host is in the running state of insecurity, it could have serious consequences:

Increasing the operating load host, resulting in damage to the main motor and electrical system. Screw, screw between before and after the end of the screw and the frame between, between the strong friction will make the host running load increase sharply, in addition operation load bearing has been badly worn and will be of great.Thus, the motor will be in a state of work overload, would seriously endanger the safe operation of motor. If the case is severe, if the electrical protection device reaction air compressor is not sensitive or failure, it may also lead to motor burn.

Attenuation of air compressors will greatly. The host with increasing gap will lead to host efficiency decrease, namely air compressors produce attenuated greatly, affect the gas production units of the policy. Especially for those users who displacement compressor configuration rich smaller, the attenuation due to air compressors, gassystem in gas consumption relatively stable situation, pipe network pressure of compressed air can be reduced a lot, may appear with gas equipment can not work normally or root of this not work, which appears to influence the normal productionunit or cause temporary shutdown, a loss for the enterprise..

All of a sudden death "the most serious consequences is the emergence of the host".Once this happens, if the electrical protection system response is not timely or failure,may also lead to serious damage to the main motor and electrical system.

Chi and air compressor water heater technical engineer to remind you: for the"locking", on the one hand overhaul repair costs will be more expensive than the normal overhaul, on the other hand, because the host components will be damaged,so the comprehensive performance of repair after the host will also teach normaloverhaul of the host to be worse.

Reminder.

Chronicles and the electromechanical device limited company to recommend air compressor, water heater, air compressor heat recovery equipment, as long as youhave the air compressor factory, can 0 operation cost of producing hot water andheating.

(this paper mainly analyze compressor head bearing overhaul decision tips, but in actual in the problem solving process is for reference only.)
