How to improve the lubrication efficiency of textile machinery?

Lubrication of textile equipment involves many links such as procurement, storage, technology, management and maintenance, which is a systematic project. It is an important way to improve the economic benefits of enterprises to correctly select the type and mark of lubricating oil, properly keep the lubricating oil, ensure the normal operation of equipment, and extend the service life of equipment. In this issue of "Forum Voice", let's listen to what good methods and suggestions netizens have for improving the lubrication efficiency of textile machinery.
Lubrication requirements
The old model equipment made in China (such as 1452A warping machine, G142B sizing machine, 1515 loom, etc.) has low speed, low load and low requirements for lubrication. However, the speed and load of new equipment (such as high-speed warping machine, double sizing tank sizing machine, shuttleless loom, etc.) have been greatly improved, their lubrication requirements have also been correspondingly improved, and the lubrication methods have also been changed, such as centralized oil supply, oil bath lubrication, etc. are widely used.

Imported textile equipment has the characteristics of high speed, large load and good reliability of equipment operation. Most of its transmission forms are gear boxes. Most of the supporting points of the transmission shaft adopt rolling bearings, which improves the transmission reliability and also changes the lubrication mode. In the new type of textile equipment, centralized circulating lubrication or gearbox oil bath lubrication are mostly used, so the anti-oxidation, antirust and antifouling properties of lubricating grease are required to be better.

Under normal circumstances, most of the lubricating grease marked in the instructions of imported equipment are products of world famous companies with good performance. As long as the equipment is lubricated as required, normal operation of the equipment can be guaranteed. During the lubrication work, the oil circuit must be prevented from blocking, the label of the lubricating oil must be paid attention to, and the oil level display window of the lubricating oil must be checked frequently to avoid mechanical damage caused by lack of oil. According to the lubrication requirements of the equipment, a detailed lubrication cycle shall be worked out, and lubrication shall be carried out in strict accordance with the principle of fixed person, fixed quality, fixed point, fixed quantity and fixed time. At the same time, corresponding inspection means shall be provided to ensure the lubrication quality.

Selection of lubricating oil
When purchasing lubricating oil, pay attention to its physical and chemical performance indicators, such as viscosity, corrosion resistance, rust resistance, flash point, water content, impurity content and acid value. During production, the types and grades of lubricating oil shall be reduced as much as possible according to the actual performance of the equipment, operating conditions and the instructions of the lubricating oil manufacturer, taking into account the comprehensive economic benefits, meeting the lubricating requirements and facilitating management, so as to reduce the purchase and storage costs.

The lubricating oil can be selected according to the type and mark specified in the equipment specification. Imported lubricating oil 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. Domestic lubricating oil can be considered for unimportant parts to reduce operating cost.

Storage and custody of lubricating oil
In order to prevent the oxidation and deterioration of lubricating oil, it shall not contact with copper, lead and other non-ferrous metals during storage. During the storage of the original barreled lubricating oil, it shall be kept clean, dark, cool, and ventilated. All types and grades of lubricating oil shall be marked conspicuously to avoid confusion.

The storage time of lubricating oil should not be too long, generally not more than 1 year, so as not to affect the lubrication effect due to deterioration. Therefore, the storage quantity should be strictly controlled. Some lubricating oils need to be naturally precipitated for a certain period of time before use. For example, hydraulic oils need to be stored for one week after purchase before being put into use, so that impurities can be fully precipitated. Therefore, some lubricating oils should be put into use without purchase.

Precautions for maintenance
The supporting points of the rotating parts of the machine are easily polluted by dust, resulting in increased friction resistance and increased mechanical wear. Pay special attention to abrasive wear during equipment maintenance and lubrication. The dust left at the lubricating point during assembly, the invasion of external dust due to poor sealing, the pollution caused by poor lubricant management, the metal powder generated during the initial operation due to poor running in, and the poor filtering device of the lubricating system will all cause abrasive wear. The source of wear particles is related to maintenance operation and lubrication quality, so it is extremely important to strengthen maintenance operation and lubrication management.

Whether the maintenance and operation methods are correct has a great impact on the sports wear condition. Whether it is clean during maintenance and whether the test cloth is clean will affect the wear process. If the bearing is replaced, pay attention to the cleaning work. The dust, impurities or moisture in the lubricating grease will greatly wear the bearing. When the content of impurities increases from 0 to 0.5%, the wear can increase by 5 to 10 times. The amount of lubricating grease shall be appropriate, generally 1/2~1/3 of the bearing cavity.

The use and management of hydraulic oil is higher than that of general lubricating oil. Practice has proved that the working performance of the hydraulic system depends to a large extent on the selection, storage and use of hydraulic oil. At least 75% of the failures of the hydraulic transmission system are caused by unreasonable selection of lubricating oil or improper storage and use, so special attention should be paid.

In the daily management, the filter screen of the hydraulic system shall be cleaned regularly. The clean filter screen can ensure the performance of the hydraulic oil. The impurities shall be removed in time. The disposable filter screen must be replaced regularly. The parts to be replaced shall be cleaned before installation. When repairing or cleaning the valves, cylinders, oil tanks, etc. of the hydraulic system, the wipers shall not be cotton yarn, cotton cloth, etc., but silk cloth or vinyl resin sponge. When replacing the hydraulic oil, the dirt of the hydraulic system must be thoroughly cleaned. After cleaning, the hydraulic oil with the same mark shall be used for replacement. The oil pump shall be opened and heated to 60 ℃ for at least 2 hours. The replacement oil shall circulate continuously for at least 24 hours, or be filtered by the filter and the fluid bag until there is no dirt. The hydraulic oil can only be used after being filtered by 150 mesh/25.4mm ～ 200 mesh/25.4mm filter screen.
