升降平臺液壓系統(tǒng)壓力不足啥原因?
1.四川升降平臺液壓泵是都能夠輸出液壓油,若無液壓油輸出則可能是沈陽升降平臺液壓泵的轉(zhuǎn)向不對,應(yīng)調(diào)整電機(jī)相位,若有液壓油輸出,則應(yīng)檢查各回油管,可能是調(diào)定壓力低。Sichuan lifting platform hydraulic pump can output hydraulic oil, without hydraulic oil output may turn right Shenyang lifting platform hydraulic pump, should adjust the motor phase, if the hydraulic oil output, it should check the return pipe, may be adjusted in low pressure.
2.四川升降平臺壓力油從高壓腔向低壓腔泄露,可能是由于安全閥沒關(guān)嚴(yán),也可能是因為活塞桿或活塞處的密封圈損壞。Sichuan lifting platform pressure oil from the high pressure chamber to the low pressure chamber leak, may be due to the safety valve is not closed, it may be because the piston rod or piston seal ring damage.
3.四川升降平臺液壓泵吸油不足,濾油器堵塞,應(yīng)清洗或更換濾油器。Sichuan lifting platform hydraulic pump, oil filter plugging, oil filter should be cleaned or replaced.
4.液壓泵發(fā)熱,油溫過高 液壓泵損壞,應(yīng)更換新的四川升降平臺液壓泵,油液粘度過高,應(yīng)選用合適的粘度,冷卻不足應(yīng)改進(jìn)冷卻系統(tǒng)。High temperature heat pump, hydraulic pump damage, should be replaced with new Sichuan lifting platform hydraulic pump, oil viscosity is too high, we should select appropriate viscosity, insufficient cooling cooling system should be improved.
5.液壓泵轉(zhuǎn)速過低,皮帶打滑,聯(lián)軸節(jié)和原動機(jī)出現(xiàn)故障應(yīng)排除。The hydraulic pump speed is too low, the belt slipping, coupling and motive of failure should be excluded.
6.若四川升降平臺液壓泵輸出流量隨壓力升高而顯著減小,且壓力達(dá)不到規(guī)定值,則是因泵損壞之后間隙增大所致,應(yīng)進(jìn)行修配或更換。If Sichuan lifting platform hydraulic pump output flow with high pressure decreased significantly, and the pressure is not up to the specified value, is due to pump damage after the gap increases due to repair or replacement should be carried out.
7.若四川升降平臺整個系統(tǒng)能建立正常壓力,而某些管路或液壓缸、馬達(dá)中無壓力,可能是管里小孔,節(jié)流閥,換向閥等部位堵塞,應(yīng)逐個檢查壓力和有無油液通過找出原因加以排除。If Sichuan lifting platform of the whole system can establish normal pressure without pressure or some pipeline hydraulic cylinder, motor, may be tube holes, throttle valve, reversing valve and other parts should be checked one by one block, and there is no pressure oil through to find out the reason to be excluded.
