  • The development trend of petrochemical system with explosion-proof motor

    Petrochemical system with explosion-proof motor(1) Increased safety and no spark machine demand will rise。Petrochemical system users in the use of practice;Has realized the development of our country the necessity of increasing safety and no spark motor。(2) The reliability of the explosion-proof electric motor have been petrochemical system user attention increasingly。Petrochemical enterprise development increasingly equipments、Continuous operation,Request system running long period、Maintenance free or less maintenance。So,Explosion-proof motor becomes the key equipment to ensure the above requirements。(3) Explosion-proof and efficient frequency conversion motor has become a petrochemical user pressing for the development of energy-saving products。There are two aspects to explosion-proof motor energy conservation work:One is developing efficient explosion-proof electrical products,The second is to develop various kinds of explosion-proof motor speed control special products,In particular will have great energy saving

  • The development trend of mining explosion-proof motor

    Mine explosion-proof motor(1) Development of high power motors:Coal winning machine in the world's biggest installed capacity is already over1200kw,The drive motor power600kW;That meet the needs of the largest installed capacity of mining coal face scraper conveyor is already over1500kW,The drive motor power has reached725kW。The domestic coal winning machine is the most high power drive motor400kW,Scraper conveyor is the most high power drive motor315kW。(2) Development3.3kV、6kVAnd10kVVoltage level of mining machine:This is because the popularity after the comprehensive mechanized coal mining area to lengthen,Lead to the increase of the voltage drop,At the same time, the use of high-power motor for higher voltage class。(3) Developing mining double speed motor:In order to adapt to the coal mine belt conveyor starting and low speed
