Drive unit with chain, belt, gear and other mechanical drive, hydraulic drive and electrical drive, the power is passed to the draw works, rotary table and mud pump working machine. Diesel engine driven rig, which has two kinds of mechanical transmission and hydraulic transmission, the latter varies with the working machine load change and automatic stepless variable speed and torque of good dynamic performance, widely used in drilling rig. Electric drive drilling rig is widely used in deep well and offshore <a href="http://www.solvedrilling.com/Shakerscreen/">Shaker screen</a>. Divided into two categories: (1) dc generator power, diesel engine or gas turbine driven dc motor, referred to as "straight - dc drive; (2) alternating current (ac) by silicon controlled rectifier drive dc motor, hereinafter referred to as cross - dc drive. The advantages are: flexible, installed power utilization high power distribution, by the power supply, without other auxiliary ac power system, high economic benefit, has become the main development direction. If you would like to ask where needs drilling equipment, we first reaction should be <a href="http://www.solvedrilling.com/Shaleshaker/">shale shaker</a>. In the coal mine production, due to the easily spontaneous combustion of <a href="http://www.solvedrilling.com/Desander/">Desander</a> seam mining, traces of goaf coal is more comprehensive, might occur during the period of stoping goaf coal spontaneous combustion, especially when the working face advancing speed slow, spontaneous combustion risk bigger, so corresponding fire prevention and fire extinguishing measures must be adopted. Mine adopts fire-fighting are yellow, aerosol, the goaf grouting nitrogen injection, etc., which are mainly composed of yellow grouting. Grouting is a routine measure of fire prevention in the process of mining, has the advantages of economic, convenient, reliable, yellow grouting technology is mature, and grouting fire extinguishing effect of long-term, reliable and is the first choice for preventing and extinguishing methods.
