Elevator hydraulic cylinder maintenance升降机液压油缸维护保养

    液压系统的执行元件之一就是液压油缸,液压油缸的主要工作就是负责直线升降或伸缩的作用。它的特点就是质量轻、功率大、结构简单、维修方便、运动惯性小、频繁换向,易于实现远程控制。液压油缸在多种类型的机械中获得了广泛的应用。

    下面就以双作用单活塞液压缸作为例子分析液压能转化成活塞直线运动的机械能。所谓的输入液压能是指输入液体所具有的流量与压力,输出的机械则是活塞直线运动时所具有的速度和牵引力。所有这些参数都是靠工作容积的变化来实现的,所以说液压缸是一种容积式的执行元件。

    为了要满足各种机械的不同的需要,液压缸具有多种结构和不同性能,按其液压力作用方式可分为单作用式液压缸和双作用式液压缸,按其结构特点可分为柱塞式液压缸和活塞式液压缸,伸缩式液压缸和摆动式液压缸,都称为液压缸,相当于升降机的心脏,那我们怎样来文虎液压油缸呢?

    第一,要防锈:因为液压油缸的活塞部分在工作状态中要伸出油缸的,自然就会收到氧化物的酸性气体的侵蚀,这就需要我们给他涂适量的油脂进行保护,以免作为承重部件的活塞受侵蚀而工作中可能发生折断;第二要开箱更换液压油:因为长时间使用,难免会有异物进入液压油缸中,这样在使用中就会发生摩擦增大的想象,另外,液压油也是有一定的使用寿命的,长时间不换油会会损坏或者侵蚀液压油缸内部,液压油缸要使用的久一点就在液压油缸的工作中要控制速度适当,不要超过2米/s,这样可以延长液压油缸的使用寿命,另外为了保护机构和安全起见,内部安装缓冲装置对于液压油缸的保护是十分有效的。

    因为液压油缸要承受很大的压强,负载越重,它的压强就会越大,因此,做好液压油缸的保养工作是整个液压系统的维护最重要的一环,而且,液压油缸就相当于液压系统的心脏,心脏处问题很难修补,所以液压油缸的维护就是要特别谨慎。

One of the executive components of the hydraulic system is the hydraulic cylinder, the main work of the hydraulic cylinder is responsible for the function of linear lift or expansion. Its features are light weight, large power, simple structure, convenient maintenance, small inertia, frequent commutation, easy to achieve remote control. Hydraulic cylinders have been widely used in many types of machinery.
The following is a double-acting single piston hydraulic cylinder as an example to analyze the hydraulic energy into the linear motion of the piston mechanical energy. The so-called input hydraulic energy refers to the flow and pressure of the input liquid, and the output machinery is the speed and traction of the piston when it moves in a straight line. All these parameters are dependent on the change of working volume to achieve, so that the hydraulic cylinder is a volumetric actuator.
In order to meet the needs of the various mechanical, hydraulic cylinder has a variety of different structure and performance, according to the hydraulic pressure methods can be divided into single acting cylinders and double-acting hydraulic cylinder, according to their structural characteristics can be divided into piston hydraulic cylinder and piston hydraulic cylinder, telescopic hydraulic cylinder and the oscillating hydraulic cylinder, is called a hydraulic cylinder, equivalent to the heart of the elevator, hydraulic oil cylinder that we how to v?
First, rust prevention: because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally receive the corrosion of acid gas oxide, which requires us to give him the right amount of grease for protection, so as to prevent the piston as a load-bearing part from being eroded and may break during work; Second out to replace the hydraulic oil: for use for a long time, one will have a foreign body into the hydraulic oil cylinder, this will increase friction in the use of imagination, in addition, the hydraulic oil also has the certain service life, no oil change for a long time will damage or erosion of the hydraulic oil cylinder, hydraulic cylinder to use longer on the hydraulic oil cylinder to control the speed of the job properly, not more than 2 m/s, it can prolong the service life of hydraulic oil cylinder, the other in order to protect the institutions and be on the safe side, the internal installation buffer device is very effective for the protection of the hydraulic oil cylinder.
Because the hydraulic oil cylinder to bear a lot of pressure, the heavier load, the pressure will be greater, therefore, do a good job in the maintenance of hydraulic oil cylinder is the maintenance of the hydraulic system is the most important one annulus, and the hydraulic oil cylinder is equivalent to the hydraulic system of the heart, heart problem is very difficult to repair, so the maintenance of the hydraulic oil cylinder is to be especially careful.
