How to carry out lubrication management project for industrial equipment of cement plant
Date：2019-08-26 15:36 Source：cementepcViews:
Cement production equipment with large scale, high load, hydraulic transmission use more characteristics.The choice of lubricating oil should be determined by its speed, load, friction pair form, working environment.
1.Lubrication characteristics of equipment and selection requirements of lubricating oil
Lubricating oil can be divided into grease, lubricating oil and solid lubricant.
As for the new dry process plant equipment, there are many types of equipment, running speed and load are different.The types and labels of lubricating oils used are also different.The selection of lubricating oil products can be carried out in accordance with the type and label specified in the equipment specification and the actual production situation.Lithium grease is basically used for dry oil lubrication, and special grease is only used for special requirements.Thin oil lubrication to meet the lubrication of gear transmission gear oil, other lubrication point is also as far as possible to choose gear oil lubrication;The solid lubricant with high temperature resistance and wear resistance should be used for the lubrication points with higher lubrication requirements, such as belt backing plate of rotary kiln.This reduces the variety of oil used in the factory, which is convenient for the management of lubricating oil and saves the cost.
2. Purchase and storage of lubricating oil
2.1 when purchasing lubricating oil.
Pay attention to the physical and chemical properties of the lubricating oil, such as viscosity, corrosion resistance, rust resistance, flash point, water content, impurity content and acid value.According to the actual performance of the equipment, operating conditions and the instructions of lubricating oil manufacturers, the types and labels of lubricating oil should be reduced as much as possible under the principle of considering comprehensive economic benefits, meeting the lubrication requirements and being conducive to management, so as to reduce the purchase and storage costs.However, the key and important parts of the imported equipment should use imported lubricating oil as much as possible to improve the lubrication performance, reduce energy consumption and extend the service life of the equipment. Domestic lubricating oil can be used in other parts to reduce the operating cost.
2.2 storage and storage of lubricating oil also have an important impact on the performance of lubricating oil.
(1) establish a special warehouse to store lubricating oil products
(2) the warehouse should be kept dry, and strictly prevent moisture from mixing into the oil, in order to prevent the oil emulsification deterioration.
(3) the storeroom should be kept clean and the container mouth covered tightly.
(4) reverse loading or sending and receiving oil products during storage and transportation.Containers and refill containers should be kept clean.
(5) after the lubricating oil enters the factory.Especially important equipment and key equipment with lubricating oil products.The main physical and chemical indicators must be re-examined.
(6) lubricating oils must be kept separate from different types and grades of oils and fats, and should be clearly marked.
3.Daily management of equipment lubrication
3.1 a feasible lubrication management organization shall be established.
Organize the whole process of lubrication oil supply, storage and use management;Investigation on lubrication management shall be carried out to accumulate lubrication technical documents;To solve the problems from the formulation of oil and wiping material demand plan, oil quality inspection, substitution and blending until storage and distribution, to meet the needs of the normal operation of the workshop equipment: to discuss and formulate the oil consumption standard and oil change cycle of the machine type, according to the actual quota of oil, oil change.Prevent waste, at the same time to take measures to save oil leakage: make oil scrap standard, strengthen waste oil recovery and recycling: organize training courses, often help professional management and laboratory personnel, inspection workers, maintenance workers to improve the professional knowledge of lubrication management, master the lubrication rules, correct lubrication maintenance equipment.
3.2 strictly implement the lubricating oil filtration system
Because the qualified lubricating oil into the plant before the application of equipment lubrication parts, generally have to go through several container turnover and position movement, every turnover of containers or moving position should be a filter, in order to prevent secondary contamination of impurities.
3.3 do a good job in monitoring the state of lubricating oil
Use the method of field sampling and testing to do well the condition monitoring of lubricating oil, timely grasp the use of oil, completely change the method of changing oil by cycle, truly achieve energy saving and consumption reduction.
3.4 leakage control of hydraulic and large lubrication equipment
The control of oil leakage of hydraulic and large lubrication equipment is also a very important part of the normal operation of hydraulic and large lubrication equipment, the specific content is as follows: the oil leakage equipment to make a detailed investigation, the location and cause of oil leakage registration, and make the corresponding treatment plan in time, timely treatment.To prevent further expansion of the spill or other accidents caused by the spill;If frequent oil spills are found, thorough and detailed investigations should be carried out to find out the causes and correct unreasonable places or ways so as to reduce the occurrence of oil spills;At the same time, according to the severity of oil leakage, the preparation of hydraulic, lubrication equipment leakage plan.And make the concrete implementation of leakage control scheme and construction drawings.
3.5 equipment lubrication fault management
On the basis of a comprehensive grasp equipment lubrication conditions, according to the laws of the equipment lubrication failure, through the instrument of lubricating equipment information collection and analysis, comprehensive understanding equipment lubrication failure reason, make timely and effective control of the equipment lubrication failure, and at the right time to take reasonable measures to finally be handled correctly, to ensure the safe operation of the equipment.
3.6 active maintenance
Hydraulic and lubrication system maintenance from the past simple fault repair, development to fault prediction, that is, in the emergence of a fault, maintenance in advance, remove the hidden trouble, to avoid the occurrence of malignant accidents.
In short, the lubrication management of cement plant equipment is a complex system engineering.How to manage the lubrication from the types of oil, procurement, storage, use, add and change oil, and so on, still need to continue to explore and research, in order to use good, manage the equipment to accumulate experience, make the equipment lubrication management work more perfect.
