The loader load sensing system can reduce the power demand of the loader to an amazing degree. The loader is equipped with an electronic servo control and information system, which is composed of LCD and keyboard to display and record various information. Its automatic diagnosis function records machine faults and stores all relevant information, Anti theft computer management and monitoring through coding is an important symbol of the development of foreign loaders in the 1990s. The computer management and monitoring system can continuously manage / monitor dozens of parameters of loaders, has fault diagnosis and alarm functions, can record and process various information of loader operation, and can display the working status of components with LCD

連桿機(jī)構(gòu)可承受大的扭矩載荷，具有卓 越的可靠性、耐用性和平行舉升機(jī)構(gòu)相類似的作業(yè)性能工作裝置能以水平位置提升或降下放在托板上的物料，可配用多種作業(yè)裝置，大限度地減少司機(jī)由地面到高度對(duì)鏟斗傾斜角的調(diào)整。

The connecting rod mechanism can bear large torque load and has excellent reliability and durability, which is similar to the operation performance of the parallel lifting mechanism. The working device can lift or lower the materials placed on the support plate in a horizontal position. It can be equipped with a variety of working devices to greatly reduce the adjustment of the bucket inclination angle by the driver from the ground to the height.

裝載機(jī)在工作3000小時(shí)之后，會(huì)出現(xiàn)儀表臺(tái)、駕駛室抖動(dòng)現(xiàn)象，且抖動(dòng)現(xiàn)象越來(lái)越嚴(yán)重，以駕駛室、整機(jī)也產(chǎn)生抖動(dòng)。抖動(dòng)現(xiàn)象造成該機(jī)物料稱重不準(zhǔn)確，無(wú)法正常使用。下面山東裝載機(jī)的技術(shù)人員給大家分析一下引起抖動(dòng)的原因有哪些？

After the loader works for 3000 hours, the instrument panel and cab will shake, and the shaking is becoming more and more serious, so that the cab and the whole machine also shake. The shaking phenomenon causes the material weighing of the machine to be inaccurate and cannot be used normally. Next, the technicians of Shandong loader will analyze the causes of jitter?

1、裝載機(jī)液壓系統(tǒng)采用轉(zhuǎn)向優(yōu)先方式，轉(zhuǎn)向泵輸出的壓力油與工作泵輸出的壓力油合流后向工作裝置供油。工作泵只有在工作裝置動(dòng)作時(shí)才承受負(fù)荷，而轉(zhuǎn)向泵不但在工作裝置動(dòng)作時(shí)承受負(fù)荷，轉(zhuǎn)向時(shí)也承受負(fù)荷，因此轉(zhuǎn)向泵工作時(shí)間相對(duì)較長(zhǎng)、磨損較大。

1. The hydraulic system of the loader adopts the steering priority mode. The pressure oil output by the steering pump flows with the pressure oil output by the working pump and supplies oil to the working device. The working pump only bears the load when the working device acts, and the steering pump not only bears the load when the working device acts, but also bears the load when steering. Therefore, the working time of the steering pump is relatively long and the wear is large.

2、裝載機(jī)在優(yōu)先閥閥體、閥芯、調(diào)壓彈簧和壓力油的共同作用下，EF口開啟與閉合按照一定頻率相互變換，便發(fā)生一定頻率的振動(dòng)。由于該振動(dòng)與儀表臺(tái)、駕駛室的固有振動(dòng)頻率接近，導(dǎo)致儀表臺(tái)、駕駛室發(fā)生共振。

2. Under the joint action of priority valve body, valve core, pressure regulating spring and pressure oil, the opening and closing of EF port of loader change with each other according to a certain frequency, and vibration of a certain frequency occurs. The vibration is close to the natural vibration frequency of the instrument panel and cab, resulting in resonance of the instrument panel and cab.
