目前大型钻机柴油机的启动是用24伏电瓶的直流电源,电瓶制造费用高,搬迁易损坏,尚需专用直流充电设备。特别是在严寒地区打井,气温在摄氏零下30°以下时,电容严重降低,不易起动柴油机,造成管线冻结及其他工程事故。因此,为钻机柴油机的启动寻求安全直流电源,革电瓶的命是由来已久的问题。随着硅元件的发展和应用,我们发现天津电焊机厂生产的ZS—500硅整流弧焊机,是用硅管作桥式整流的。
The current large-scale rig diesel engine is started with 24-volt battery DC power supply, battery manufacturing costs, easy to move easily damaged, still need special DC charging equipment. Especially in hard winter drilling wells, the temperature below minus 30 ° C, the capacitor is seriously reduced, not easy to start the diesel engine, causing pipeline freezing and other engineering accidents. Therefore, to find a safe DC power supply for the start-up of diesel engine, leather battery life is a long-standing problem. With the development and application of silicon components, we found that ZS-500 silicon rectifier arc welding machine produced by Tianjin Welding Machine Factory is made of silicon tube for bridge rectification.
