1、用感官直接判斷升降貨梯http://m.zjfutures.cn/液壓元件的質(zhì)量。眼睛觀察各類儀表的指示狀況、執(zhí)行元件的速度與轉(zhuǎn)速、執(zhí)行元件運(yùn)動(dòng)連貫與協(xié)調(diào)情況、各類操作控制器件的安裝與連接狀況、各類工作指示燈與故障指示燈的情況、各類控制線路的連接情況、液壓油的油面、氣泡、顏色與渾濁程度等；用耳朵判斷液壓泵是否有功率輸出、是否有氣蝕、液壓泵運(yùn)動(dòng)件與軸承是否損壞、泵或馬達(dá)是否有干磨擦、系統(tǒng)內(nèi)是否存在泄漏口、是否存在液壓沖擊與炮鳴現(xiàn)象等； 用手感覺液壓元件表面溫升情況，通過觸摸液壓元件外壁或液壓管道，也可判斷其中是否有油流過，以及流過的油是否具有較高的壓力；嗅覺主要用于判斷液壓油是否變質(zhì)、電磁線圈是否燒蝕。
With sensory directly determine the quality of cargo lifter hydraulic components. Circumstances indicate the status of various types of instruments eye observation, the speed and the speed of the actuator, the actuator motion coherence and coordination, installation and connection status of various types of operation control device, all kinds of work and fault indicator lights, all kinds of control connection line, surface, bubbles, color and turbidity degree of hydraulic oil and other oil; with ears to judge whether the pump power output, if there is cavitation, whether hydraulic moving parts and bearing damage, the pump or motor is dry friction are there leaks in the system mouth, whether there is a hydraulic shock and gun Ming phenomenon; hand feeling surface temperature rise of hydraulic components, hydraulic components by touching the wall or hydraulic pipes, which can also determine whether there is oil flows, and flows whether oil has a high pressure; olfactory hydraulic oil is mainly used to determine whether the deterioration of the electromagnetic coil is ablation.
2、用壓力表或流量計(jì)測(cè)試升降貨梯液壓元件的質(zhì)量。要正確選擇壓力表的量程與精度要正確選擇能準(zhǔn)確反映液壓元件狀態(tài)的測(cè)點(diǎn)，根據(jù)液壓系統(tǒng)的工作機(jī)理，推測(cè)相關(guān)元件磨損以后，有關(guān)點(diǎn)的壓力值將發(fā)生什么樣的變化，由此判斷升降貨梯液壓元件的損壞情況。
Elevating the quality of freight elevator hydraulic components with a pressure gauge or meter test. To gauge the correct choice to select the correct range and precision measuring points can accurately reflect the state of the hydraulic components, according to the working mechanism of the hydraulic system, presumably related components after wear, pressure points related to what kind of changes will take place, which determine the lift freight elevator damage hydraulic components.
3、通過測(cè)試執(zhí)行升降貨梯http://m.zjfutures.cn/元件的速度或轉(zhuǎn)速判斷系統(tǒng)狀態(tài)，通過測(cè)試升降貨梯液壓元件表面溫度判斷元件狀態(tài)。
Cargo lifter components through test execution speed or speed determine system status, cargo lifter hydraulic components by testing to determine the surface temperature of the element status.
