河北升降货梯http://www.rgsjpt.com/液压泵诊断手段可分为便携式简易诊断和在线精密诊断两大类别。河北升降货梯液压泵故障的预兆主要参数是压力降低，流量减少，温度上升，变量速度超时，噪音上升与振动增大，液压泵内泄漏量超标等。检测不同参数时，应根据液压泵所反映出来的实际状况，现场条件和精度要求的差异，选择不同的测量方法和工具，仪器。
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.

河北升降货梯液压泵检测仪器可以较快的从液压泵的外部直接检测出液压泵内部磨损情况，从而有效地防止了液压泵的故障发生，提高了主机的可靠性。 河北升降货梯液压泵检测还可以采用液压测试仪检测液压泵的总效率。液压测试仪是由流量，压力表和温度计所组成，可联接到液压泵的排口，通过调节仪器的各项功能检测出液压泵排口在各级压力下的流量，绘制出液压泵总效率曲线图。
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.

河北升降货梯http://www.rgsjpt.com/液压泵测试仪与液压泵泄油口联接检测液压泵内泄量，液压泵的泄漏量是随在线使用时间而变化的，在固定的周期时间内，测出泄漏量的变化就可相应得知液压泵影响系统能否正常工作的运行状态变化，将泄漏量随时间变化的曲线称为状态曲线，作为液压泵工作状态的评定指标，可用以进行故障预报和维修期的确定。
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.
