Description
Technical field
The present invention relates to lubricant oil detection technique field, be specifically related to a kind of gear reducer lube detection device based on Electrostatic Absorption and using method thereof.
Background technique
Lubricant oil is used in all kinds mechanically to protect the fluid lubricant of machinery and workpiece; be widely used in the transmission device such as the motor of boats and ships, vehicle etc., compressor and retarder; there is material impact to gearing loss and life-span thereof, can effectively blocking member wearing and tearing and corruption light up.
For retarder, most fault is all relevant with lubricant oil, the rotten of lubricant oil directly reduces lubrication effect, wearing and tearing between aggravation transmission part and temperature rise, the inefficacy of the parts such as accelerating gear, bearing, cause a series of decelerator trouble, greatly shorten the normal service life of retarder.
Lubricant oil in use for some time, due to lubricant oil itself can be oxidized, condense, hydrolysis etc., or the cause of invasions such as introduced contaminants, particle, moisture can cause lubricant oil oil deterioration, reduce its greasy property, the lubricant oil oil deterioration that particularly impurity such as water and iron filings can cause sharply declines, and the key property that result in its lubrication sharply declines.Just effectively can not play lubrication at part surface after deterioration of lubricant, and bring the impurity effects such as iron filings into due to lubricant oil, accelerate the wearing and tearing on transmission part surface, thus need often more oil change to ensure the normal work of retarder.
The operator needing experience extremely to enrich due to Lubricating Oil quality could only judge with visually observing, general operation personnel are difficult to judge, further, even veteran operator sometimes also can error in judgement, the too early or too late replacing of lubricant oil is caused.In addition, because retarder is closed lubrication, need could extract lubricant oil after retarder quits work and dismantles, therefore, the replacing of general gear reducer lube all can not judge that lubricant oil is the need of replacing in advance, but according to previous experiences, when just more oil change after one period of set time of retarder work, namely the front deceleration device oil change cycle is fixed.But the different applying working condition lower replacement cycles has difference, more oil change can waste lubricant oil too early, and increase retarder maintenance cost, too late more oil change can affect retarder lubrication effect, and then affects service behaviour and the working life of retarder.
In sum, current gear reducer lube only also change by rule of thumb by the fixed cycle, and oil change is too early or too late thus, is difficult to the lubricated maintenance cost reducing retarder while ensureing oil lubrication performance.
Therefore, need one at present badly and accurately can judge Lubricating Oil quality technology, the lubricant oil maintenance cost of retarder can be reduced while ensureing oil lubrication performance.
