Problems solved by technology
However, with continuous use for a long time, the fuel injection volume will be seriously reduced; the electrical system cannot continue to work normally; the gear (dry oil) fuel injection system is often blocked, resulting in no fuel injection
The tooth surface of the gear is often dry-grinded, which causes serious vibration of the bearing housing; the large tile is often heated due to insufficient lubrication, and it needs to be stopped for maintenance in severe cases
As a result, the entire lubrication system operates under abnormal conditions, and its operational reliability cannot be guaranteed

Embodiment Construction
[0011] A method for automatic lubrication and refueling of a ball mill. When starting to work, the air compressor first generates compressed air with a pressure of 0.6MPa. The compressed air reaches the nozzle plate through the filter, triple parts, air circuit and total air valve, and the nozzle on the nozzle plate After purging once, the nozzle plate is equipped with corresponding nozzles according to the width of the lubricated gear surface. The oil pump pumps the oil from the oil tank to the nozzle plate. At the nozzle, the lubricating oil and compressed air are mixed into mist and sprayed out. The high-viscosity lubricating oil is sprayed on the bearing surface of the gear in a mist form to form a tough oil film, so that the gear maintains a good lubrication state and the service life is improved.
[0012] The original automatic lubricating device of the ball mill had the following problems: (1) The valve flap of the thin oil pump was broken many times, causing the thin oi...

The invention relates to an automatic lubrication oil injection method of a ball mill. The automatic lubrication oil injection method of the ball mill is characterized by comprising the following steps of: firstly, lubricating an oil chamber and introducing compressed air into the oil chamber when operating a lubricator of a fully-automatic oil-injection lubrication device; blowing a nozzle on a nozzle plate to ensure that an orifice of the nozzle is unblocked; and then starting an oil pump to pump the lubrication oil from an oil tank to the nozzle plate; at the nozzle position, spraying the lubrication oil after the lubrication oil is mixed with the compressed air; spraying the high-viscosity lubrication oil on the lubrication stress surfaces of a main bearing, a big gear, a speed reducer and a rolling bearing of the ball mill so as to form a tough oil film and maintain an excellent lubrication state. The automatic lubrication oil injection method of the ball mill of the invention has the advantages of high reliability, strong control capability, easy control, capability of being applied to lubrication of the main bearings and the big gears of a plurality of boiler ball mills to realize that the ball mill can inject oil once operated, obvious economic benefit of energy conservation and consumption reduction, and simple maintenance.
Description
technical field [0001] The invention relates to an automatic lubricating and oiling method for a ball mill. Background technique [0002] The ball mill is the main equipment of the pulverized coal boiler pulverization system, and is responsible for the main task of providing qualified pulverized coal for the boiler. The operation of the boiler is directly related to the operation of the ball mill. To ensure the good operation of the ball mill, lubrication is a major factor. The lubrication of the ball mill is mainly divided into four parts: large tile lubrication, large gear lubrication, reducer lubrication, and rolling bearing lubrication. Among them, the big tile lubrication is wool lubrication at first, that is, adding lubricating oil to the wool, so that the wool is fully immersed in oil, and the lubricating oil is transferred to the hollow shaft by the contact between the wool and the hollow shaft to play a lubricating role. The lubricating oil is for one-time use; t...
