The purpose and classification of lubrication management for cotton spinning equipment

A, the purpose of cotton spinning equipment lubrication management

The purpose of cotton spinning equipment lubrication management is to effectively reduce the friction of the work surface, eliminate a series of adverse effects due to friction, such as energy loss, equipment life shortening, machine efficiency reduction, etc., in addition to lubricants can also flush dirt, prevent surface corrosion, the formation of lubricant film between the friction surface, the original contact surface of the dry friction for separation, change dry friction for grease molecules between the oily friction, thus Reduce the friction resistance of dynamic machine parts, reduce the inherent wear and tear of equipment, reduce the damage between rotating machine parts and bearings, effectively avoiding the heat of machine parts and bearings under load, and having a certain role in heat dissipation and volatilisation, ensuring high quality and efficient operation of equipment, and ensuring advanced performance and good condition of equipment.

Due to the diversity of cotton spinning equipment, enterprises should be based on their own equipment type, the mechanical structure of each process characteristics, the speed of the transmission parts of the high and low, different workshop environmental state and other factors, to take different lubrication management methods, the use of suitable for the characteristics of the process equipment lubricating grease, so that the equipment rotating parts always keep “oil running” of the state.

B, the cotton spinning lubrication way of classification

1, the classification of lubrication state

According to the cotton spinning equipment movement form, can be divided into three kinds of lubrication state: (1) liquid lubrication: two friction lubrication:

(1) liquid lubrication: two friction between a layer of sufficient thickness and strength of the oil film, so that the friction between completely separated, and not contact.

(2) boundary lubrication: two friction between a very thin film of oil, in the liquid lubrication and dry friction between the state.

(3) semi-liquid lubrication: between the two friction sub-projections, making the friction sub-surface discontinuous oil film state.

2, the classification of lubrication

According to the different lubricating grease, can be divided into grease lubrication and oil lubrication two major lubrication methods.

(1) grease lubrication is divided into: manual lubricating grease, grease gun plus lubricating grease two types, some rotating parts sealed tight, parts hidden in the equipment inside, need oil cycle long, generally in the equipment size repair to manual manual refueling. For some rotating speed, oil consumption time cycle short parts, general equipment manufacturers are equipped with oil nozzle, such as: equipment parts of the roller bearings, spindle and high-speed drive shaft are equipped with oil nozzle, convenient maintenance personnel with oil gun refueling.

(2) oil lubrication is divided into oil bath lubrication, continuous oil flow lubrication, intermittent oil flow lubrication, dispersion of micro-droplet and oil mist lubrication five types, these five types of lubrication in the cotton spinning process equipment has been widely used, and strip, strip and roll machine, combing machine, spinning machine and other transmission gear box, coarse yarn machine winding parts of the oil bath self-lubrication, coarse yarn, spinning head gear intermittent oil lubrication, etc., in the production of all play The oil bath self-lubrication of coarse and fine yarn head gears plays an active role in lubrication.
