1、 Advantages of hydraulic elevator

1、土建结构要求低。液压电梯无需机房，只需一面承重墙，高度2600mm以上就可以安装，底坑也可以做到很浅，100mm，由于液压家用电梯对土建要求低的优势，在十五年前引入国内时迅速占领了大部分家用电梯市场。

1. The requirements for civil structure are low. The hydraulic elevator does not need a machine room. It only needs a load-bearing wall. The top floor can be installed with a height of more than 2600mm. The bottom pit can also be very shallow, with a minimum of 100mm. Because of the advantage of low civil engineering requirements of the hydraulic domestic elevator, it quickly occupied most of the domestic elevator market when it was introduced into China 15 years ago.

2、不会超速失控。不会发生冲顶、蹲底的情况，只要机械结构设计合理，安装可靠，液压式电梯的系数比较高，而且液压电梯可以利用后备电池，来实现困人自救功能，在电梯故障或停电困人的时候，按下轿厢内部的应急按钮，接通泄油阀门电路后的液压油慢慢回到油箱后，电梯靠自重慢慢下降。

2. Will not overspeed out of control. There will be no bumping to the top or squatting to the bottom. As long as the mechanical structure is designed reasonably and installed reliably, the safety factor of the hydraulic elevator is relatively high, and the hydraulic elevator can use the backup battery to realize the rescue function of trapped people. In case of elevator failure or power failure and trapped people, press the emergency button inside the car, connect the oil drain valve circuit and the hydraulic oil slowly returns to the oil tank, and the elevator will slowly decline by its own weight.

3、节约建筑空间。相比曳引式电梯有对重，液压式电梯没有对重，只有两根轨道。所以比较节省建筑空间。楼梯口位置1100*1100就可以安装。

3. Save building space. Compared with the traction elevator, the hydraulic elevator has no counterweight and only two rails. So it can save building space. The stair exit can be installed at 1100 * 1100.

二、液压电梯的缺点

2、 Disadvantages of hydraulic elevator

1、有一定的电机噪音。电梯在启动上行时，电机和油泵工作时机械音会听的很清楚，形成噪音污染。

1. There is certain motor noise. When the elevator is started up, the mechanical sound will be heard clearly when the motor and oil pump are working, resulting in noise pollution.

2、会泄露液压油。油缸活塞的使用寿命到期后，或存在磨损时，液压油就会渗漏到井道内，维修清理起来比较麻烦，也不利于。

2. Hydraulic oil will leak. After the service life of the cylinder piston expires, or there is wear, the hydraulic oil will leak into the shaft, which is troublesome to repair and clean, and is not conducive to environmental protection.

3、隐患。受制于液压的特性，长时间不用，会下沉造成不平层，给轮椅和老人进出轿厢造成隐患。同时液压油的粘稠度会因为温度的差异而变化（特别是北方地区更加明显），对电梯运行的效率和舒适度、性造成影响。

3. Potential safety hazard. Due to the characteristics of hydraulic pressure, if it is not used for a long time, it will sink and cause uneven layers, which will cause safety hazards for wheelchair and elderly to enter and leave the car. At the same time, the viscosity of hydraulic oil will change due to the temperature difference (especially in northern areas), which will affect the efficiency, comfort and safety of elevator operation.
