New coal mining gateway with crusher shaft set of lubrication system

Group of new coal mining gateway with crusher shaft lubrication system is 2019 - 12 - 28 abstract: in recent years, the economic development of our country has obtained great achievement, at the same time of rapid economic growth of energy consumption is also put forward higher request. Coal in the energy consumption in China is a very important part of, in the process of coal transportation along the groove in the role of the crusher is very important, when faced with a large lump coal or strip coal, the crusher to break, or to the belt machine will break belt, and the use of the crusher is good or bad, is essential to the broken shaft lubrication requirement. Key words: coal mine; Gateway crusher; Broken shaft group; Lubrication 1, foreword with the improving of the coal mine production capacity, maintenance of equipment also appears especially important. Crusher shaft group as the most important parts of the crusher, when coarse coal through crusher shaft the blade on the group assumes the role of broken coal, bear the impact is very large, the inside of the shaft set lubrication of bearings and seal is particularly important. Specially thick coal seam sub-level caving mining, in particular, due to large coal height, are more likely to form a big lump coal ( Rock) Take a fall, coarse coal ( Rock) After transmission chance to crusher, the bigger impact crusher shaft group. Group 2, the traditional crusher shaft lubrication method as shown in figure 1 1, grease lubrication, commonly used crusher shaft group of traditional crusher shaft lubrication using manual lubrication pump, the crusher shaft group for grease, lubrication and broken shaft set of bearing and seal. Its operation is simple, and small volume, easy to put. But this lubrication way too dependent on manual workers, can not effectively control the broken shaft group 'for fat time interval' and 'for fat time if forgotten as workers or other reasons, makes the lubrication is not timely, group is the first damaged shaft bearing, bearing once damaged, will directly cause the broken shaft group of dysfunctional, coarse coal more time will also appear in the crusher with coal, coal wall condition, underground coal transportation from otherwise normal operations, seriously affect the normal production safety and efficiency of coal mine. Group 3, new crusher shaft lubrication system to meet the requirements of high yield and efficient mechanized mining face, based on the current situation, with a new type of crusher shaft set of lubrication system is imperative. 3. As shown in figure 1-1, the operation way 2, the crusher shaft group electric lubricating system, including the installation on the crusher frame of multi-point pump device and electric control device, a multipoint f oil pump device through electronic control device for its' time for fat and 'for fat interval setting, make the grease inside the crusher shaft group always maintain sufficient condition. 3. 2, the principle to fat have conditions and under the action of electric control device, select the function switch ( Three gear) Your choice ( 'manual' or 'automatic' and 'stop') , when the conversion to open concern to manual mode, the motor on the pump start randomly, until the people off; When converting a concern to automatic, automatic pump on the motor start, when the work for fat time is set to 'time for fat, pump automatically enter the resting time ( Also called for fat time interval) Only when resting time at the end of the pump and then repeat the last work mode. F oil pump device in qualifications for fat and under the action of electric control device, through the function switch ( 'manual' or 'automatic' status and stop) For 'for fat time' and 'for fat interval setting. Matching the electronic control system has a 'low liquid level alarm, when oil tube liquid level is low, the low liquid level indicator on the panel light, electric control system at this time just for storage tank filling grease, crusher shaft group for fat enough can be ensured.
