液压电梯的性能特点

一、液压电梯有什么不一样的性能特点?
1、 What are the different performance characteristics of hydraulic elevator?
当液压系统管路破裂、轿厢失速下降时,可自动切断油路。油箱油温保护。当油箱中油温超过某一值时,油温保护装置发出信号,暂停电梯使用,当油温下降后方可启动电梯。载重量大。液压系统的功率重量比大,因此同样规格的电梯,可运载的重量大。噪声小。液压系统可采用低噪声螺杆泵,同时泵、电动机可设计成潜油式结构,构成一个泵站整体,能够大大降低噪声的影响。防爆性能好。液压电梯采用低凝阻燃液压油,油箱为整体密封,电动机、液压泵浸没在液压油中,能防止可燃气体、液体的燃烧。
When the hydraulic system pipeline breaks and the car stalls and drops, the oil circuit can be cut off automatically. Oil tank oil temperature protection. When the oil temperature in the oil tank exceeds a certain value, the oil temperature protection device sends a signal to suspend the use of the elevator. When the oil temperature drops, the elevator can be started. Heavy load. The power weight ratio of the hydraulic system is large, so the elevator of the same specification can carry large weight. Low noise. The hydraulic system can adopt low-noise screw pump, and the pump and motor can be designed into submersible structure to form a whole pump station, which can greatly reduce the impact of noise. Good explosion-proof performance. The hydraulic elevator adopts low condensation flame retardant hydraulic oil, the oil tank is sealed as a whole, and the motor and hydraulic pump are immersed in the hydraulic oil, which can prevent the combustion of combustible gas and liquid.
二、液压电梯的原理是什么?
2、 What is the principle of hydraulic elevator?
液压电梯运行分上行和下行。电梯下行时,打开阀组,利用轿厢自重[客(货)的重量]造成的压差,使液压油回流液压油箱中,实现电梯的下行运动,此时液压泵站不消耗功,轿厢下行的速度是由液压系统中阀组开启的大小来控制的。电梯上行时,由液压泵站提供电梯上行所需的动力压差,液压系统中的阀组控制泵中液压油的流量,当液压油进入缸内油腔中,液压油推动液压油缸中柱塞来提升轿厢,从而实现电梯的上行运动,此时液压泵消耗的功为实际功。
The operation of hydraulic elevator is divided into up and down. When the elevator goes down, open the valve group, and use the pressure difference caused by the self weight of the car [the weight of passengers (goods)] to make the hydraulic oil return to the hydraulic oil tank to realize the downward movement of the elevator. At this time, the hydraulic pump station does not consume work, and the downward speed of the car is controlled by the opening size of the valve group in the hydraulic system. When the elevator goes up, the hydraulic pump station provides the power differential pressure required for the elevator to go up. The valve group in the hydraulic system controls the flow of hydraulic oil in the pump. When the hydraulic oil enters the oil chamber in the cylinder, the hydraulic oil pushes the plunger in the hydraulic cylinder to lift the car, so as to realize the upward movement of the elevator. At this time, the work consumed by the hydraulic pump is the actual work.

三、液压电梯内部的组成结构有什么?
3、 What is the internal structure of the hydraulic elevator?
压控制系统由单向阀、集成阀块、液压系统控制电路等组成,其功能是控制电梯的运行速度,接收输入信号并操纵电梯的启动、运行、停止。液压缸及支承系统液压缸及支承系统的功能是直接带动轿厢的运动。液压缸:将液压系统输出的压力能转化为机械能,通过柱塞的机械运动来带动轿厢的运动。)支承系统:根据支承方式的不同,支承机械部件有很大差别。导向系统由导靴、导轨和导轨支架组成,其功能是限制轿厢的活动自由度,使轿厢只能沿着导轨作升。
The pressure control system is composed of one-way valve, integrated valve block and hydraulic system control circuit. Its function is to control the running speed of the elevator, receive the input signal and operate the start, operation and stop of the elevator. Hydraulic cylinder and support system the function of hydraulic cylinder and support system is to directly drive the movement of lift car. Hydraulic cylinder: converts the pressure energy output by the hydraulic system into mechanical energy, and drives the movement of the lift car through the mechanical movement of the plunger.) Support system: there are great differences in supporting mechanical components according to different support methods. The guide system is composed of guide shoes, guide rails and guide rail supports. Its function is to limit the freedom of movement of the car so that the car can only be raised along the guide rails.
