When mining machines are used for a period of time, we should do standing test and maintenance, so that we can guarantee machine safety operation and prolonging service life. As for flotation separator maintenance, the general provision is that overhaul every 12 years for, 2 times one year for medium maintenance. And for minor repair, generally two times one year. But when comes to the bad working conditions, the minor repair should be four times one year. After decades of efforts, the mining machinery industry in China has got vigorous development, but compared with foreign industry, there is still a considerable gap in developing level, especially in the open-air mining equipment and underground transport equipment; on the mining machinery products, there is a certain gap in manufacturing quality, appearance, reliability, longevity and design levels and test methods with the advanced industrial countries; Having join the WTO, in order to accelerate the development of basic industries, we must accelerate the development of mining machinery and research speed. Knife gate operator should stand by the side.
When starting mining equipment, not persona should be around. In order to prevent arc burn, operators are required to comply with the operation rules in these situations, such as starting machine, using double knife start machine, star point or auto-voltage-reduced starting. When several sets of machines start at at time, operators should start one by one and from large ones to small ones. If you have to start one machine several times, you must obey the relative operation rules and shall leave appropriate stop time. In order to prevent overheated, the number of successive starting times shall not exceed 35. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like jaw breaker, Henan Hongxing is always doing the best in products and service. As the professional manufacturer of complete sets of machinery, such as combination crusher mining, HXJQ is always doing the best in products and service.
When coming across abnormal operation sound, or machine stop working or slowly rotating eleven started, the operators shall constantly stop machine for test. Regular testing of mining machinery 1. Note the machine overheated phenomena. 2. Observe equipment value rating. 3. Pay attention to the change of power voltage. 4 Watch the equipment vibrating condition. 5 Watch the degree of three-phase and three-phase currents voltage unbalance. 6 Pay attention to sound and smell of equipment operation. Watch out for machine stop accident. When that of things happened, you should cut off power at once. If one of the following things happened to your machines, please stop machine for test. 1. Personal injury accident happens when operation. 2 The rotating speed slows down finds, and at the same time, equipment give out heat and strange noise. 3. When the machine is at fire debido a conveying device broken off. 4. The bearing of mining equipment exceeds the regulated heat value. And the current exceeds the regulated statement, or finds increaser. 5 Strong vibrating happens when in operation. 6 The standing maintenance of mining equipment. In addition, the coal company managers too much emphasis on production, to pursue the maximization of economic benefits, security is not strong, induction training for employees not in place, resulting in some operators cannot properly grasp the use of advanced equipment, leading to existing equipment cannot play its technological advantage. cement rotating dryer: cone crusher manufacturer:
