升降貨梯http://www.it616.com.cn/是采用液壓機構作為動力進行工作的，每個部件都有著與眾不同的作用，下面濟南天銳升降機械的有關技術人員就給大家介紹一下液壓部件的工作原理。
升降貨梯的液壓油由葉片泵構成相應的壓力，經濾油器、隔爆型電磁換向閥、節流閥、液控單向閥、平衡閥進入液缸下端，使液缸的活塞向上運動，晉升重物，液缸上端回油經隔爆型電磁換向閥回到油箱，其額外壓力經過溢流閥進行調整，經過壓力表調查壓力表讀數值。升降貨梯油缸的活塞向下運動，升降貨梯液壓油經防爆型電磁換向閥進入液缸上端，液缸下端回油經平衡閥、液控單向閥、節流閥、隔爆型電磁換向閥回到油箱。
The upward movement of the piston hydraulic cargo lifter oil constituted by the corresponding pressure vane pump, the filter, explosion-proof solenoid valve, throttle check valve, balance valve into the lower end of the hydraulic cylinder, the liquid cylinder , heavy promotion, the upper end of the hydraulic cylinder return oil through flameproof solenoid valve to the tank, the extra pressure relief valve after adjustment, after investigating the gauge pressure gauge readings. Cargo lifter cylinder piston moves down, cargo lifter hydraulic oil through the 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, flameproof electromagnetic commutation valve back to the tank.
為使升降貨梯http://www.it616.com.cn/重物降低平穩，制動安全可靠，在回油路上設置平衡閥，平衡回路、堅持壓力，使降低速度不受重物而改變,由節流閥調理流量，操控升降速度。為使制動安全可靠，防止意外，添加液控單向閥，即液壓鎖，確保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，以差異超載或設備毛病。
In order to reduce heavy cargo lifter stable, safe and reliable braking, set the balancing valve, balancing loop back to the oil on the road, adhere to the pressure to make changes to reduce speeds without the weight, by the throttle flow conditioning, speed control movements. In order to secure the brake to prevent accidents, add check valve, hydraulic lock that is to ensure that when an unexpected burst hydraulic lines can safely self-locking. Installed voice alarm overload, overload or to differences in equipment problems.
