本文涉及一种矿山机械,特别涉及一种矿山提升机电动机热能回收防结露系统。该系统其特征是:在提升机电动机的强制通风冷却排风管处加装一回风管,回风管接入冷却系统进风室,强制通风冷却排风管与回风管出口处分别设置电动多叶调节阀。因此,该系统的效果是:采用热回收技术加热电动机冷却进风温度,既能通过强制通风冷却方式将电动机工作所产生的热量带走,防止电动机温升过高,又能有效地防止电动机绕组出现结露现象,提高电动机绝缘效果和工作效率,从而保证提升机能够正常运行。
This invention relates to a mining machinery, in particular to a mine hoist motor heat recovery anti-condensation system. The system is characterized in that: a return air pipe is installed at the forced draft cooling exhaust pipe of the hoisting machine motor, the return air pipe is connected to the air inlet room of the cooling system, the outlet of the forced draft air cooling exhaust pipe and the return air duct are respectively set Electric multi-leaf valve. Therefore, the system has the following effects: the heat recovery technology is used to heat the motor to cool the intake air temperature, both the heat generated by the motor operation can be removed by forced ventilation and cooling to prevent the temperature of the motor from rising too high and the motor winding can be effectively prevented The phenomenon of condensation appears to improve the insulation effect and work efficiency of the motor so as to ensure the normal operation of the hoist.
