        小型裝載機負載感應變速控制系統能縮短作業循環,降低燃油消耗率達15%,提高作業效率和作業經濟性同時能減少因行駛方向改變或因發動機處于高轉速時換擋所造成的換擋沖擊,減輕司機的工作疲勞。
        The load sensing variable speed control system of small loader can shorten the operation cycle, reduce the fuel consumption rate by 15%, improve the operation efficiency and operation economy, reduce the shift impact caused by the change of driving direction or the shift when the engine is at high speed, and reduce the driver's work fatigue.
        裝載機負荷傳感系統可把裝載機對動力的需求減少到驚人的程度,裝載機上配有電子伺服控制及信息系統由液晶顯示屏和鍵盤組成,用來顯示和記錄各種信息,其自動診斷功能記錄機器故障并儲存所有相關信息,通過編碼可以防盜計算機管理和監控是90年代國外裝載機發展的一個重要標志計算機管理監控系統能連續管理/監控裝載機的數十項參數,具有故障診斷和報警功能,能記錄、處理裝載機作業的各種信息,并能用液晶顯示器顯示部件的工作狀態。
        The load sensing system of the loader can reduce the demand of the loader for power to an amazing extent. 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 all kinds of information of loader operation, and can display the working state of components with LCD.
        連桿機構可承受非常大的扭矩載荷,具有很好的可靠性、耐用性和平行舉升機構相類似的作業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,可配用多種作業裝置,更大限度地減少司機由地面到更大高度對鏟斗傾斜角的調整。
        The connecting rod mechanism can bear very large torque load and has good reliability and durability. It has similar operation performance with the parallel lifting mechanism. The working device can lift or lower the materials on the support plate in a horizontal position. It can be equipped with a variety of working devices to reduce the adjustment of bucket inclination angle from the ground to a greater height.
        裝載機在工作3000小時之后,會出現儀表臺、駕駛室抖動現象,且抖動現象越來越嚴重,以至駕駛室、整機也產生抖動。抖動現象造成該機物料稱重不準確,無法正常使用。下面山東裝載機的技術人員給大家分析一下引起抖動的原因有哪些?
        After the loader works for 3000 hours, the instrument panel and cab will shake, and the shaking phenomenon 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、裝載機液壓系統采用轉向優先方式,轉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作時才承受負荷,而轉向泵不但在工作裝置動作時承受負荷,轉向時也承受負荷,因此轉向泵工作時間相對較長、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, while 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、裝載機在優先閥閥體、閥芯、調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,便發生一定頻率的振動。由于該振動與儀表臺、駕駛室的固有振動頻率接近,導致儀表臺、駕駛室發生共振。
        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. Because the vibration is close to the natural vibration frequency of the instrument panel and cab, the instrument panel and cab resonate.
