河北升降貨梯http://www.qdysj.net/液壓泵診斷手段可分為便攜式簡易診斷和在線精密診斷兩大類別。河北升降貨梯液壓泵故障的預(yù)兆主要參數(shù)是壓力降低，流量減少，溫度上升，變量速度超時(shí)，噪音上升與振動(dòng)增大，液壓泵內(nèi)泄漏量超標(biāo)等。檢測不同參數(shù)時(shí)，應(yīng)根據(jù)液壓泵所反映出來的實(shí)際狀況，現(xiàn)場條件和精度要求的差異，選擇不同的測量方法和工具，儀器。
Shandong cargo lifter pump portable diagnostic tools can be divided into simple diagnostic precision diagnostics and online two categories. Shandong omen main parameters cargo lifter hydraulic pump failure is the pressure reduction,flow is reduced, temperature rise, the variable speed timeout, increased noise and vibration is increased, such as excessive leakage within the hydraulic pump. When the detection of different parameters, as reflected in the pump should be based on the actual situation, differences in site conditions and the precision required to select different measurement methods and tools, instruments.

河北升降貨梯液壓泵檢測儀器可以較快的從液壓泵的外部直接檢測出液壓泵內(nèi)部磨損情況，從而有效地防止了液壓泵的故障發(fā)生，提高了主機(jī)的可靠性。 河北升降貨梯液壓泵檢測還可以采用液壓測試儀檢測液壓泵的總效率。液壓測試儀是由流量，壓力表和溫度計(jì)所組成，可聯(lián)接到液壓泵的排口，通過調(diào)節(jié)儀器的各項(xiàng)功能檢測出液壓泵排口在各級壓力下的流量，繪制出液壓泵總效率曲線圖。
Shandong cargo lifter pump testing equipment can quickly from the outside of the hydraulic pump directly detect the internal wear of the hydraulic pump, thereby effectively preventing the hydraulic pump failure, improves reliability of

the host. Shandong cargo lifter pump detection can be also used to detect the overall efficiency of the hydraulic pump hydraulic tester. By the flow of hydraulic tester, pressure gauges and thermometers composed, may be coupled to the hydraulic pump discharge port, by regulating the function of the instrument detects the pump discharge port flow under pressure at all levels, to map out the overall efficiency of the pump graph.

河北升降貨梯http://www.qdysj.net/液壓泵測試儀與液壓泵泄油口聯(lián)接檢測液壓泵內(nèi)泄量，液壓泵的泄漏量是隨在線使用時(shí)間而變化的，在固定的周期時(shí)間內(nèi)，測出泄漏量的變化就可相應(yīng)得知液壓泵影響系統(tǒng)能否正常工作的運(yùn)行狀態(tài)變化，將泄漏量隨時(shí)間變化的曲線稱為狀態(tài)曲線，作為液壓泵工作狀態(tài)的評定指標(biāo)，可用以進(jìn)行故障預(yù)報(bào)和維修期的確定。
Shandong cargo lifter pump tester and hydraulic pump drain connection is detected within the discharge volume, hydraulic pump leakage is online with the use of time and change, within a fixed period of time, measured changes in the amount of leakage can be corresponding change in operating status that affect pump system can work properly, the leakage rate varies with time curve is called the state of the curve, as the pump working state assessment indicators can be used to perform fault prediction and determination of the maintenance period.
