Distributed automatic lubricating system

Abstract

The invention relates to a distributed automatic lubrication system, which includes an upper HMI human-machine interface, a controller, a conversion adapter, an on-site oil replenishment machine and a communication system. The upper HMI human-machine interface consists of an industrial computer or an integrated workstation, system software, application The program structure, the controller is composed of programmable logic controller PLC, the conversion adapter is set between the controller and each on-site oil replenishment machine, and the body of the on-site oil replenishment machine is equipped with a reusable oil storage cup, which is directly set on each lubrication Under the control of the upper HMI human-machine interface, automatic oil replenishment is carried out with constant pressure, timing and quantity, which will neither damage the oil seal of the bearing chamber nor reduce the quality of grease, and can avoid oil leakage and lubrication poor performance. Set and adjust parameters such as the working cycle of each on-site oil replenishment machine through the upper HMI human-machine interface, and monitor the operation status of each on-site oil replenishment machine, related working bearings and the entire lubrication system, which is conducive to ensuring good lubrication working conditions.

Description

technical field [0001] The invention relates to the technical field of bearing maintenance, in particular to a distributed automatic lubricating system which is convenient for long-distance, regular and quantitative supply of lubricating oil, and which can remotely monitor the working status of each lubricating point. Background technique [0002] In the daily work of rolling bearings, a certain amount of dry oil and lubricating grease is consumed and replenished every day, so whether the corresponding lubricating grease can be replenished in time according to the actual consumption situation becomes the core of rolling bearing lubrication and maintenance. Therefore, the grease replenishment cycle, the amount of grease replenishment and the quality of the grease replenished have become the three main points in the lubrication and maintenance of rolling bearings. At present, the commonly used grease replenishment methods for rolling bearings mainly include concentrated grease...

Problems solved by technology

[0004] ①Because the distance between the center of the oil reservoir and each lubrication point is not equal, it is easy to form a situation where the bearings with a short distance are over-greased and the bearings with a long distance are insufficiently greased, so the amount of grease added to each lubrication point is uneven;

[0005] ②Because the grease pipeline is usually long, the pressure required for grease injection is relatively high, so that the oil seal on the bearing with a short distance is often damaged due to excessive pressure, resulting in leakage of grease because it cannot be stored in the bearing chamber Oil phenomenon, resulting in bad situation of grease waste and environmental pollution;

[0006] ③Because most of the lubrication points are far away from the center of the oil reservoir, the grease travels in the pipeline for a long time, and some may even exceed one year, resulting in a serious decline in the quality of the grease reaching each lubrication point and affecting the lubrication effect;

[0007] ④ Long-distance oil transportation under high pressure is prone to oil-soap separation and pipeline blockage. The pipeline must be pickled regularly to ensure smooth oil passage, so the workload of daily maintenance is relatively large

Its disadvantages are: refueling based on experience, the amount of refueling is not easy to control; manual refueling operations cannot be implemented for toxic and harmful lubrication points that cannot be touched by hands; time-consuming, laborious, dirty and tiring, and do not meet environmental protection and economic requirements

However, the existing traditional centralized fat replenishment system can only meet the requirements of the fat replenishment cycle, and it is difficult to guarantee the amount of fat replenishment and the quality of the fat; the artificial fat replenishment method can only meet the requirements of the quality of the fat, but it is difficult for the fat replenishment cycle and the amount of fat replenishment. ensure

More importantly, there are many and scattered oil replenishment points on the production site. Whether it is traditional centralized grease replenishment or manual grease replenishment, due to technical constraints, it is impossible to monitor the lubrication of each oil replenishment point in real time, especially the key points. state, leading to accidental damage to the bearing, and often stop production, causing huge economic losses to the enterprise
