Textile equipment lubrication management
Doing a good job of lubrication management of textile equipment is an important part of the management of textile enterprises. Strengthening equipment lubrication management, ensuring the normal operation of equipment, saving energy, reducing maintenance costs, and extending the service life of equipment are important ways to improve the economic efficiency of textile enterprises.
Lubrication requirements for textile equipment
The lubrication of textile machinery and equipment should be determined according to its speed, load and friction pair form, which are clearly marked in the general instructions, and should be strictly implemented in accordance with requirements in production.
Imported textile equipment has the characteristics of high speed, large load, and good reliability of equipment operation. Most of its transmission forms use gear box transmission. Most of the support points of transmission shafts adopt rolling bearings. While improving the transmission reliability, it has also changed. Lubrication method.
In the new textile equipment, most of them adopt centralized circulation lubrication or gear box oil bath lubrication. Therefore, the oxidation resistance, rust resistance and stain resistance of lubricating grease are required to be better. The lubrication cycle of imported textile equipment is described in detail in its manual. The parts that need to be lubricated every day, week, month and quarter are clearly marked and should be strictly implemented in production. Under normal circumstances, most of the lubricating greases marked in the instructions of imported equipment are products of world-renowned companies, and their performance is good. As long as the lubrication is performed in accordance with regulations, the equipment can operate normally.
In the lubrication work, it is necessary to prevent the oil circuit from being blocked, pay attention to the label of the lubricating oil, and check the oil level display window of the lubricating oil frequently to avoid mechanical damage caused by oil shortage and economic loss. In the daily lubrication management, according to the lubrication requirements of the equipment, a detailed lubrication cycle must be worked out. Lubrication should be strictly performed in accordance with the fixed number, fixed quality, fixed point, quantitative and timing "five fixed". At the same time, corresponding inspection methods must be provided to ensure Lubrication quality, to ensure the normal operation of the textile equipment, and to exert the normal efficiency of the equipment.
Selection and storage of lubricants
There are many types of textile equipment, running speed and load are different, and the lubricants used are also different. There are many types and labels of lubricating oils, and it is particularly important to properly select the types and labels of lubricating oils and the storage of lubricating oils. The selection of lubricating oil can be carried out according to the type and number specified in the equipment manual. When choosing a lubricant, pay attention to the physical and chemical properties of the lubricant, such as the viscosity, corrosion resistance, rust resistance, flash point, water content, impurity ratio, and acid value of the lubricant.
According to the actual performance of the equipment, the operating conditions and the instructions of the lubricant manufacturer, production should be based on the principle of comprehensive economic benefits, which can meet the requirements of lubrication, and is conducive to management. Purchase and storage costs. Imported lubricants must be used for key and important parts of imported equipment to improve lubrication performance, reduce energy consumption, and extend the service life of equipment. Consider using domestic lubricants for less important parts to reduce operating costs.
The storage and storage of lubricating oil has an important impact on the performance of the lubricating oil. Petroleum products are susceptible to decomposition when they come into contact with light, heat and non-ferrous metals, especially copper, or chemical reactions with oxygen in the air, generate extremely unstable oxides, and even colloids and acidic substances, which seriously affects Its use performance, even the corrosion effect and damage the machinery. In order to prevent the oxidative deterioration of lubricating oil, it should not be in contact with non-ferrous metals such as copper and lead during storage. The original barreled lubricating oil should be kept clean, protected from light, cool and ventilated. To avoid confusion between types and labels.
The storage time of the lubricating oil should not be too long, generally should not exceed 1 year, so as to avoid deterioration and affect the lubrication effect, it is necessary to strictly control the storage quantity. Some lubricating oils need to be naturally precipitated for a certain period of time before they can be used. For example, hydraulic oils need to be stored for one week before being put into use to allow the impurities to fully precipitate. Therefore, some lubricating oils need to master the principle of not being purchased.
Problems to pay attention to when lubricating equipment
The operating environment of textile equipment is relatively poor, and most of them operate in a state with high dust content. The support points of the rotating parts of the machine are susceptible to dust pollution, resulting in increased frictional resistance and increased mechanical wear. Pay special attention to abrasive wear during equipment maintenance and lubrication. Abrasive wear is abnormal wear caused by abrasive particles (fine sand, iron filings, dust, etc.) on the two friction surfaces, which is extremely serious for mechanical wear.
Abrasive wear is caused by poor maintenance and lubrication management, assembling carelessly remaining dust at the lubrication point, poor sealing, intrusion of external dust, contamination due to poor lubricant management, poor running-in metal powder generated during initial running-in, and poor lubrication system filtering device Etc. will cause abrasive wear. The wear of abrasive particles has a great impact on the life of the machine. The wear and tear in the industry accounts for about 50%. It is regarded as the enemy of industrial machinery damage and should be paid enough attention.
During the storage and storage of lubricating oil, the container must not be stored in the workshop without a cover, and the refueling tools must be cleaned regularly to prevent the lubricating oil from being contaminated and causing increased wear. In the maintenance work, the replacement of machine parts and the replacement of lubricants should be done carefully. The wiper cloth of the replacement machine parts must be cleaned. The cloth of important parts should be cleaned before use to avoid dust contaminating the machine parts. The lubricating parts of the parts must be thoroughly cleaned, and the installation parts must be cleaned thoroughly.
Good lubrication management to improve comprehensive benefits
The lubrication of textile equipment is an important work content of textile enterprises. Lubrication is also called preventive maintenance, which mainly lies in preventing equipment accidents and improving equipment productivity and increasing economic benefits. Doing a good job of equipment lubrication management can improve the equipment operation rate, reduce the failure rate, reduce maintenance costs, and extend the service life of the equipment. In particular, it is extremely important to ensure the normal operation of equipment for key processes such as sizing machines, warping machines, and air compressors
