液壓升降機(jī)液壓油由葉片泵形成一定的壓力，經(jīng)濾油器、隔爆型電磁換向閥、節(jié)流閥、液控單向閥、平衡閥進(jìn)入液缸下端，使液缸的活塞向上運(yùn)動，提升重物，液缸上端回油經(jīng)隔爆型電磁換向閥回到油箱，其額定壓力通過溢流液壓升降機(jī)閥進(jìn)行調(diào)整，通過壓力表觀察壓力表讀數(shù)值。
lift oil vane pump is formed by a certain pressure, the oil filter, explosion-proof solenoid valve, throttle valve, check valve, balance valve into the lower end of the cylinder, so that the hydraulic cylinder piston upward sports, lifting weights, upper cylinder oil return by flameproof solenoid valve to the tank, which is adjusted by the rated pressure relief valve hydraulic lift, by observing the pressure gauge pressure gauge readings.

液壓升降機(jī)的液缸活塞向下運(yùn)動液壓油經(jīng)防爆型電磁換向閥進(jìn)入液缸上端，液缸下端回油經(jīng)平衡閥、液控單向閥、節(jié)流閥、隔爆型電磁換向閥回到油箱。液壓升降機(jī)為使重物下降平穩(wěn)，制動安全可靠，在回油路上設(shè)置平衡閥，平衡回路、保持壓力，使下降速度不受重物而變化,由節(jié)流閥調(diào)節(jié)流量，控制升降速度。為使制動安全可靠，防止意外，增加液控單向閥，即液壓鎖，保證在液壓管線意外爆裂時能安全自鎖。安裝了超載聲控報警器，用以區(qū)別超載或設(shè)備故障。
lift cylinder piston downward movement of the hydraulic oil by explosion-proof solenoid valve into the upper end of the hydraulic cylinder, hydraulic cylinder through the lower back to the oil balance valve, check valve, throttle, explosion-proof solenoid valve back to the tank. Fixed lift heavy objects fall to make a smooth, safe and reliable braking, set the balancing valve, balancing loop back to the oil on the road, keep up the pressure, so that the rate of decline from the weight change, the throttle valve regulates the flow, speed control movements. In order to secure the brake to prevent accidents and increase check valve, namely hydraulic lock, ensure that when an unexpected burst hydraulic lines can safely self-locking. Installed voice alarm overload, overload or equipment failure to distinguish.
