液壓泵是升降貨梯的核心部件，是非常重要的一個組成部分。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升降貨梯的液壓泵是如何工作的？
在液壓泵站中，液壓油由葉片泵形成一定的壓力，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，提升重物，液缸上端回油經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閥進行調整，通過壓力表觀察壓力表讀數值。
Hydraulic pump station, hydraulic oil is formed by the vane pump a certain pressure, the oil filter, explosion-proof solenoid valve, throttle valve, check valve, balance valve into the lower end of the hydraulic cylinder, the liquid cylinder the piston moves upward, lifting heavy objects, the upper end of the hydraulic cylinder return oil through flameproof solenoid valve to the tank, the rated pressure is adjusted by hydraulic lifts overflow valve, pressure gauge readings observed by the pressure gauge.
升降貨梯液壓泵油缸中的活塞向下運動(既重物下降)。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。液壓升降機為使重物下降平穩，制動安全可靠，在回油路上設置平衡閥，平衡回路、保持壓力，使下降速度不受重物而變化,由節流閥調節流量，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,用以區別超載或設備故障。
Cargo lifter hydraulic cylinder piston downward movement (both heavy falls). Hydraulic oil through explosion-proof solenoid valve into the cylinder upper end, a lower end of the hydraulic cylinder oil return by balancing valve, check valve, throttle valve, explosion-proof solenoid valve to the tank. Hydraulic lift heavy objects fall to make a smooth, safe and reliable braking, set balancing valve, balancing loop back to the oil on the road, keep pressure on the rate of decline from the weight change, the throttle valve regulates the flow control lifting speed. To enable safe and reliable braking to prevent accidents, increase the check valve, namely hydraulic lock, ensure that when an unexpected burst hydraulic line can be safely self-locking.

升降貨梯液壓泵電器控制系統通過防爆按鈕SB1—SB6來控制電機的轉動，隔爆型電磁換向閥的換向，以保持載荷提升或下降，且通過“LOGO”程序調整時間延遲量，升降臺避免電機頻繁起動而影響使用壽命。
Cargo lifter pump electrical control system through the explosion-proof button SB1-SB6 to control the rotation, explosion-proof solenoid valve motor commutation, in order to maintain the load raised or lowered, and by "LOGO" program to adjust the time delay amount, lifts avoid frequent starting and affect the life of the motor.
