Self-adaptive lubrication method, self-adaptive lubrication controller and lubricant pumping system

Abstract

The invention relates to a self-adaptive lubricating method which comprises the following steps: detecting the impurity content U1, the moisture content V1 and the effective component content W1 of oil discharged from a target lubricating point in a current detection period; according to U1, V1 and W1 and the numerical value change rates delta U, delta V and delta W of the three parameters relative to the previous detection period, calculating period estimated values U2, V2 and W2 of the three parameters in the next detection period; judging whether U2, V2, W2, delta U, delta V and delta W are in a set range or not, and when U2, V2, W2, delta U, delta V and delta W are all in the set range, keeping the lubricating period and the single-period lubricant supplement amount of the lubricating point unchanged; when U2, V2 and W2 exceed a set threshold value, or delta U, delta V and delta W exceed a set range, an alarm is given, and shutdown processing is carried out; and except for the two conditions, when the period estimated value of any parameter exceeds a set range, the lubrication system of the lubrication point is adjusted. In addition, the invention further provides a self-adaptive lubrication controller and a lubricant pumping system. According to the invention, through oil product detection, based on numerical values and change rate detection conditions of three parameters of the impurity content, the moisture content and the effective component content of the oil discharged from the lubricating point, the lubricating period of the lubricating point and the single-period lubricant supplement amount are subjected to matching adjustment, so that the self-adaptive adjustment of the lubricating system of the lubricating point can be realized; therefore, the working reliability of the lubricating point can be effectively improved, and the waste of the lubricating agent is reduced.
