This code specifies the operation content blower beneficiation plant and safety requirements. This procedure applies to the position of the blower of the concentrator. 2 content 2.1 Operators must be employed after passing safety training; wear safety helmets and employee protection kits before they are employed. Employees must wear three tight dresses; women workers must be in safety helmets, not wearing shorts, high heels, and slippers. 2.2 Before starting the car, it is necessary to thoroughly check the protective devices and safety accessories. 2.3 The inlet and outlet valves of the fan should be properly opened. 2.4 When the inspection repair, should be taken to avoid chips, scrap iron, the cloth and the like fall into the volute, in order to avoid damage to the device. 2.5 Parts cleaned with diesel oil must be operated for 10 minutes without load after starting the machine to be put into normal operation. 2.6 No repair work shall be carried out while the machine is in operation or under pressure from the equipment. 2.7 Always pay attention to the changes indicated by the lubricant pressure gauge. It is forbidden to operate beyond the specified pressure. 2.8 Regularly observe changes in the ammeter index and find that the anomaly is immediately reported and processed. 2.9 Always check if the cooling water of the fan is normal. 2.10 Frequent contact with the flotation station to use the wind to prevent the flotation post from being too small to cause the fan to vibrate too much. 2.11 Always check whether the connecting bolts of each part are firm and the pipeline seal is normal. If problems are found, deal with them in time. 2.12 Always check whether the fan vibration is normal and the running sound is normal. 2.13 Inflammable and explosive materials are not allowed in the equipment room. 2.14 After the host stops, stop the lubrication station after 5 minutes. 2.15 When the machine is shut down for a long time, the fan inlet and outlet ducts should be closed. 2.16 Responsible for the environmental sanitation of the scope of this post, clean and hygienic work, and achieve civilized production. 2.17 Fill in the original record carefully and the writing is clearly intact. 2.18 Strictly implement the handover system. 3 When the blower has one of the following conditions during operation, it needs to stop immediately: 3.1 When the blower or motor has strong vibration or there is collision and grinding inside the casing; 3.2 When the bearing is in the oil pipeline, the oil pressure is reduced to 0.3kg/cm2; 3.3 When the oil temperature of the support bearing or thrust bearing of the blower exceeds 65 °C, after using various measures, it still exceeds 65 °C; 3.4 In the fuel tank, the oil level drops to the lowest oil level, but it can still be stopped; 3.5 When there is smoke in the bearing or seal; 3.6 When a component in the unit is in danger.
