Introduction
The centralised lubrication system is a Closed-loop lubrication system, consisting of oil feeds, pipes, hoses, distributors, sprayers and other components, which are used to automatically supply lubricating oil to bearing of rotating components, in order to keep the bearing in a good lubrication state and prevent bearing wear, so as to ensure proper operation and reduce maintenance costs.
The centralised lubrication system is mainly applied in the industries with high requirements on lubrication accuracy and maintenance of machinery, such as steel rolling, automobile making and metal processing. In terms of working principle, the centralised lubrication system contains various pumps and other components, which can be used to transfer and spray the lubricants on the bearings of relevant components, when necessary, in order to prevent direct contact of the bearing with the outside air, reduce the loss of the lubricant, prolong the service life of the bearing and prolong the service life of the equipment.
Working Principle
The basic components of the centralised lubrication system are the oil reservoir, pump, pressure regulating device, measuring device, valve and hose. The working principle of the system is as follows:
First of all, the lubricant is filled into the oil tank and divided into different lubrication points according to the specific needs of the equipment. Then, when the system is running, the pump will continuously supply channels and nodes in the pipeline. The metered quantity of lubricant is delivered to each lubrication point by the control valve, and the remaining lubricants and the leakage lubricants are returned to the oil storage tank, thus forming a closed circulation system.
The pump used in the centralised lubrication system is a plunger pump or an oil-metering pump. Both types of pumps work by means of high pressure. The oil-metering pump has a metering device inside, which can accurately control the metering of lubricants. Plunger pumps, on the other hand, have no such device, but can work with high pressure, allowing for large-scale accomodation of oil, which can then be distributed to the pipelines through the pressure control valve.
The pressure controlling valve of the centralised lubrication system is the key element to ensure the efficient and accurate operation of the system. It can control the feeding pressure of the lubricant, so that the lubricant is fed to each bearing in the exact amount and at the right time. In order to ensure the reliable operation of the pressurization valve, the pressure of the lubricant should be closely monitored and adjusted through the pressure gauge.
Finally, in order to further ensure the accuracy and reliability of the lubricant system, a monitoring device can be installed at the distributor to detect the pressure and flow rate of the lubricant, and if any problem is detected, the control system will automatically stop the system to eliminate the problem.
Conclusion
The working principle of the centralised lubrication system is relatively simple, and is mainly composed of multiple pumps, pressure regulators, pipes and valves. With the above mentioned components, it can ensure the accurate and reliable lubrication of the relevant parts of the system, thus reducing the wear and tear of the machine, and extending the service life of the machine, thereby ensuring the reliability and efficiency of the system.
