煤礦用橡膠輸送帶更正確的使用方法
The most correct use method of rubber conveyor belt for coal mine
煤礦用橡膠輸送帶打滑會(huì)造成嚴(yán)重的磨損，其是在一定的條件下發(fā)生的，當(dāng)環(huán)形輸送帶的工作阻力達(dá)到摩擦力的極限值時(shí)，皮帶就會(huì)在與設(shè)備的接觸面打滑，從而使得橡膠帶無(wú)法進(jìn)行正常的運(yùn)作，還會(huì)對(duì)帶體造成較為嚴(yán)重的磨損，過程中大量的熱量將會(huì)產(chǎn)生，從而使得輸送皮帶在磨損與熱量的雙重作用下不斷損壞，直斷裂;
The slipping of rubber conveyor belt for coal mine will cause serious wear, which occurs under certain conditions. When the working resistance of annular conveyor belt reaches the limit value of friction, the belt will slip on the contact surface with the equipment, so that the rubber belt cannot operate normally, and it will also cause serious wear to the belt body, and a large amount of heat will be generated in the process, Thus, the conveyor belt is continuously damaged under the dual action of wear and heat until it is broken;
為了保證皮帶輸送機(jī)設(shè)備能夠正常的工作，因此礦用輸送帶必須要滿足以下幾個(gè)條件：
In order to ensure the normal operation of belt conveyor equipment, mining conveyor belt must meet the following conditions:
1、作用在輸送皮帶上的張力應(yīng)使得傳動(dòng)滾筒上的圓周力通過摩擦傳遞到帶體上，而橡膠輸送帶與滾筒之間必須保證不打滑;
1. The tension acting on the conveyor belt shall make the circumferential force on the transmission drum transmitted to the belt body through friction, and there must be no slip between the rubber conveyor belt and the drum;
2、作用在皮帶上的張力應(yīng)足夠大，使得礦山輸送帶在兩組托輥間的垂度小于一定值;
2. The tension acting on the belt should be large enough to make the sag of the mine conveyor belt between the two groups of idlers less than a certain value;
3、在長(zhǎng)期使用下造成的疲勞損壞是因?yàn)橄鹉z傳送帶在不斷的工作過程中造成的損壞累計(jì)，由于煤礦運(yùn)輸帶自身的工作性質(zhì)，帶體運(yùn)行時(shí)間一般較長(zhǎng)，且其中間斷時(shí)間較短，因此在煤礦生產(chǎn)過程中，工業(yè)輸送皮帶的疲勞損壞狀況相比其他環(huán)境下要大很多，由于煤渣、粉塵等的進(jìn)入，橡膠運(yùn)輸帶與機(jī)械設(shè)備表面的摩擦力不斷增加，致使帶體自身材料脫落，造成材料的脫落積累，另外由于皮帶傳輸過程中應(yīng)力的不斷變化，致使其材料內(nèi)部強(qiáng)度逐漸降低，損壞持續(xù)積累，更終造成了疲勞損壞的狀態(tài);
3. Due to the long-term fatigue of the conveyor belt in the coal mine, it takes a long time for the conveyor belt to be damaged due to the continuous fatigue of the conveyor belt in the process of coal mine production, The friction between the rubber conveyor belt and the surface of mechanical equipment is increasing, resulting in the material falling off of the belt itself and the accumulation of material falling off. In addition, due to the continuous change of stress in the process of belt transmission, the internal strength of the material is gradually reduced and the damage continues to accumulate, resulting in fatigue damage;
4. The quality of Shandong conveyor belt is affected by many aspects, such as the rubber coverage, the number of liner layers of nylon belt, the initial tension, the thermal vulcanization of rubber belt and the quality of conveyor belt joints.
