提升机液压站液压油温过高或过低都会直接影响到液压站的正常运行,对煤矿的安全生产带来隐患。通过对液压系统的热力学计算,对液压站设置冷却和加热装置提供了理论依据,并从提升机实际使用工况出发,设置液压冷却和加热装置回路,确保液压站安全稳定运行。 Hydraulic hoist hydraulic oil temperature is too high or too low will have a direct impact on the normal operation of the hydraulic station on the coal mine safety hazards. Based on the thermodynamic calculation of the hydraulic system, the theoretical basis is provided for the setting of cooling and heating devices in the hydraulic station. Based on the practical working conditions of the hoist, the circuits of hydraulic cooling and heating devices are set up to ensure the safe and stable operation of the hydraulic station.
