प्रतिष्ठापनम्
With the development of mechanical and electronic technology, industrial control technology continues to advance. Innovative electromechanical equipment liberates people from simple and repetitive labor, improves production efficiency, and reduces labor costs.
earliest lubrication methods were manual lubrication and oil cup lubrication. These methods can still be used for small equipment with few lubrication points and long refueling cycles, but are not suitable for situations with many lubrication points and large oil demand.
Later, it developed into centralized lubrication, mainly including single progressive lubrication, double line and multi line lubrication systems. This type of lubrication system has dominated the market for many years and is still widely used today. All three types of lubrication systems have the following theoretical problems that cannot be solved.
Progressive lubrication system
Principle: There is only one main pipeline, and usually a plunger pump injects lubricating grease into the main pipeline. The lubricating grease is then sent to the next level distributor through a single line progressive distributor, and finally to each lubrication point. As long as one lubrication point does not produce oil, all progressive distributors do not produce oil, and the system pressure will increase. When the alarm upper limit is reached, the system will report a fault and stop running. प्रथमः स्तराधानम्विधानं संविधायः निम्नतिरक्षणानि-

▷The fuel supply radius is small, and due to the distribution of single lines in a hierarchical manner, the requirements for the supporting pipelines cannot exceed 2 meters. If they are too long, it will directly affect the quality of lubrication. The system is only suitable for places where several lubrication points are located in close proximity.
दोषः सङ्केताहरणसंविधा
Principle: The dual line centralized lubrication system mainly consists of a lubrication pump, a directional valve, a differential pressure switch, a bidirectional distributor, an electric control box, and two oil supply pipelines. The lubricating grease output by the lubrication pump is alternately transported to the dual line distributor through the directional valve through the two oil supply pipelines, and quantitatively distributed to each lubrication point through the dual line distributor. The pressure inside the oil supply pipeline reaches the required operating pressure of the distributor, and the distributor operates. After the distributor completes its operation, the pressure inside the oil pipe continues to rise. When the pressure in the oil supply pipeline has caused the distributor to complete its operation (the system completes one oil supply run), the system pressure rises to the reversing pressure of the reversing valve, and the reversing valve switches to perform a second oil supply. विधानायाः संविधायां नीमानचित्रापणम्-

Principle: With multi-point pump as the core, different lubrication points can be connected after each outlet, and the oil volume of each outlet can be adjusted. When the lubrication pump is working, each point will discharge oil according to the adjusted oil volume. şd
When the multi point pump fails, all lubrication pumps will no longer supply oil

Based on the above centralized system s, the world's heavy industry and heavy equipment are looking forward to the emergence of a new type of dry oil lubrication system. Summarizing the advantages and disadvantages of various lubrication systems, combined with advanced automatic control technology and sensor technology in the world, a new generation of intelligent dry oil centralized lubrication system has been developed.

The working principle of the advanced intelligent lubrication system independently developed by Beijing MCC Huarun Technology Development Co., Ltd. is shown in the following figure.
The electromagnetic oil feeder is pumped in to the main pipeline through an electric high-pressure lubrication pump and integrated into an electromagnetic oil feeder on the site. The electromagnetic oil feeder integrates oil supply to lubrication points on the site by controlling the opening and closing of the solenoid valves. All lubrication pumps, grease storage tanks, and oil feeder integrations are controlled through a control cabinet. The upper computer monitoring system monitors the start and stop of the take and stop of the take and stop of the electelection pump, the main pipeline pressure, lubrication pump oil level, and other information in real time, and records the oil supply status, and records the IoIoIoIoIoIoIoIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsIsप्रत्येकः सङ्कलमनम् ।

The lubrication of other heavy equipment outside the metallurgical industry is still a relatively large market. For example, a set of engineering equipment suitable for small and medium-sized equipment such as excavators and shovels has been developed, which requires fewer lubrication points, limited installation space, and high vibration. Beijing MCC Huarun Technology Development Co., Ltd. has developed a small lubrication pump with a capacity of 6L-40L, which can fully meet the demand and has been running on some of these equipment with good results.
