Roller press as the host of grinding equipment, its operation quality directly affect the enterprise benefit, inspection maintenance work must be done.
Only do hidden dangers, fault timely detection, timely processing, a reference to prevent accident, make its good operation, create benefits for the enterprise.
Of roller press inspection maintenance, combined with its own structure, can from the following several aspects.
A, the structure of the roller press roller press in terms of its structure by the transmission parts, power, pressure system, chassis parts, rolling parts, such as feeding device of a few big.
Automation is mainly on the displacement sensor, temperature, pressure and other components at a time.
Inspection maintenance is in it.
Second, the content of the roller press inspection maintenance roller press inspection maintenance content is more, but in the aggregate, and can do a good job in several aspects of work.
1.
Power motor inspection maintenance roller machine Lord two, respectively, to determine roll and roll.
Through inspection, the first to touch, listen, detection of the stator and bearing temperature, noise, vibration, and display instrument and control or site, to see if it is consistent.
2.
Drive reducer inspection inspection of reducer, mainly check the temperature, vibration, lubrication, oil level, listen how gear and bearing noise.
Check whether the torque support is shaking exception, whether to have abnormal noise caused by loose, activity whether flexible joints, lubrication is in place, etc.
3.
Pressurized system of inspection to examine the pressurized system, main content including station is short of oil, oil, pipeline, valve leaks oil, manual switch is normal, the oil cylinder jacket is damaged, the pressure indicator is consistent with that of control.
Accumulator is drip, jig is loose, if there is a leak phenomenon, etc.
4.
Feeding device check feeding device mainly check whether wear, whether material leakage, stick the valve opening is moderate, adjust the board or other feed valve is abnormal.
5.
Frame check whether frame check including anchor bolt looseness, upper and lower beam and slab crack, whether beam-column joint bolt looseness, shear dowel is abnormal, and torsion support connection whether normal, move the clearance of roller spacing block is normal, etc.
6.
Shield check the roll cover check whether ash, whether with roller friction, and the other part of connection is normal, etc.
7.
Roller check check of the rolls, including the roll surface wear test, main bearing inspection, bearing inspection mainly temperature, lubrication, noise, vibration, check the bearing seat for skew wandering.
8.
Cooling system inspected water-cooling system includes two parts, one is whether the spindle cooling water leakage, rotary joint is flexible, water pressure, water is normal.
The second is the reducer of the cooling water is normal.
Second, roller press maintenance inspection is to found the problem, maintenance is a problem of simple processing and maintenance, to found out the problems should be hidden danger recorded, and arrange processing one by one.
Below is the roller press several key needs to be maintained.
1.
Fill oil filling oil mainly refers to the speed reducer, pressure station, station grease.
When found the shortfall in oil gas station, shall be carried out in a timely manner in accordance with the provisions, of fill oil to the normal standard calibration position, pay attention to the oil during oil filling.
If I found a little grease failure, should be clear in time to ensure oil supply, pump when necessary, to ensure the safety equipment.
When found the spill should find out the reason, timely fastening and sealing, clean up the vent can make the oil and gas discharge.
2.
Accumulator fill gas when found nitrogen air leakage, to find out the reason, in addition to normal to treat leakage, to fill gas to normal pressure, replace or repair the accumulator when necessary.
3.
Leakage of material, the processing of gray material leakage often occurs in the front-rear device or dust collecting pipe, found that the problem should be welding repair in time.
If take ash, besides check unclog the gas piping, can increase the convulsions, appropriate adjustment in the wind.
4.
Roller surface inspection process when found rolling machine vibration and abnormal noise, and with a certain cycle, cycle is likely to be foreign body in the system, must be inspection on roll surface and remove foreign bodies.
If found a local extrusion roller surface falls off, according to the normal roller surface welding method for repair, maintenance or do in the short term plan.
5.
About loose processing rolling machine has a lot of fasteners, such as anchor bolt, beam-column joint bolt, found loose should tighten in time, when necessary, the outage tighten.
6.
Water cooling system cooling system mainly reducer and roller, found leaking or insufficient water pressure, should be sealed and adjusting.
Three, other roller press inspection maintenance can't solve all the problems, if I found serious problems such as reducer broken teeth or bearing damage, the rolling machine spindle bearing damage, beams at fracture, etc. , must want to undertake maintenance.
In addition, the problems found during the inspection records must be reflected in place, avoid to cause bigger loss, on the roller surface welding must also have a detailed plan.
Because individual level is limited, the understanding of roller press or does not reach the designated position, hard to avoid improper, please comment.
Thank you very much!
