subject: Effect Of Lubrication On Elevator [print this page] 1the choice of lubricant 1the choice of lubricant
Hoist the lubricant for mineral lubricating oil and lubricants.
Selecting oil, viscosity as the main index to. The principle is when the high speed, small load, low temperature, selection of low viscosity lubricating oil; conversely, the selection of high viscosity lubricating oil.
Selection of lubricating grease, to penetration as main index. The principle is the large load, low speed, should choose penetration lower grease; conversely, the selection of high penetration of grease.
2way of lubrication
Commonly used lubricating mode has the following seven kinds:
(1): manual oil injection with oil, oil and grease gun grease.
(2): splash oiling upon rotation of the shaft parts or attached to the oil pan, oil film, the oil pool of the oil flinging up, so that the oil splash lubricating parts.
(3) the oil ring and chain lubrication : the use of sleeve on the shaft of the oil ring and the oil chain will bring oil for lubrication, lubrication part.
(4) wick, pad lubrication : the use of rainbow straw principle and capillary action for lubrication, mainly used for low speed, light load of machinery lubrication.
(5) forced lubrication: oil pump lubricating oil using intermittent pressure to the lubrication points for lubrication.
(6) oil mist lubrication : the use of compressed air and atomized oil spray lubrication points, into the. Lubricating oil in the saturation state of precipitation, in the friction surface adhesion layer of oil film, lubricates.
(7): use of lubricating oil pressure oil pump lubricating oil to obtain certain pressure, and then transported to the lubrication points. Used lubricating oil into the oil tank, cooled, filtered and then for cycle use.
Either way of lubrication, to ensure the lubrication system to work normally.
Lubrication system intact standard is: lubrication system oil quality, oil amount, oil pressure is normal, smooth circuit, flexible rotation, oil ring lubrication system oil.
In five, the main hoist operator study self-inspection of the specific content
(1) the bolt or pin shaft such as loose or damaged, should be screwed or replacement.
(2) the lubricating parts, transmission device and the bearing must maintain good lubrication, prohibit the use of unqualified oil (grease ).
(3) the brake shoe wear reaches a prescribed value, should be promptly replaced. Brake shoes and brake or brake disc such as oil, should be wiped clean.
(4) if not on time depth indicator indicating position, should be timely and to hook works, readjust.
(5) of the elastic coupling pin and ring wear out, should be promptly replaced.
(6) rolls over, rope and brake wear and other safety devices if the movement is not accurate or not enough, must immediately be adjusted or processing.
(7) the light sound signal failure or does not work, if the lamp is damaged or inaccurate position, shall be borne by the operator is responsible for replacement or adjustment; if it is an electrical fault, should contact electrical processing.
