為什么抽沙船工作時(shí)間長(zhǎng)會(huì)穿線有振動(dòng)聲音！
1.液體內(nèi)有氣體，仔細(xì)檢查砂泵及進(jìn)水管路各密封面連接螺栓有否松動(dòng)，密封墊是否損壞，泵體及管路系統(tǒng)零件有否損壞。
2.管路支撐不穩(wěn)，水泵底座或地腳螺栓松動(dòng)是造成振動(dòng)常見的原因，必須緊固各處螺栓，避免出現(xiàn)松動(dòng)。
3.砂泵與電機(jī)軸不同心，應(yīng)進(jìn)行調(diào)整，用皮帶轉(zhuǎn)動(dòng)時(shí)，轉(zhuǎn)動(dòng)帶過松或接頭接觸不良，也會(huì)引起振動(dòng)。水泵葉輪不平衡運(yùn)行中葉輪磨損或個(gè)別葉輪流道堵塞易造成振動(dòng)，有時(shí)也因軸彎曲工葉輪不良失去平衡而引起振動(dòng)。

Why pumping sand work a long time will wear line vibration sound!
1 in liquid gas, carefully check the pump and water pipes to connect the sealing surface has loose bolts, gasket is damaged, the pump and piping system has not damaged parts.
2 instability line support, pump base or anchor bolts loosening caused by vibration are common causes, various fastening bolts must be to avoid loosening.
3 pump and motor shaft, should be adjusted, with a belt rotation, rotation belt is too loose or bad connections will cause vibration. Pump impeller imbalance in the impeller wear or individual impeller flow channel blockage is easy to cause vibration, and sometimes also due to the shaft of the impeller caused by poor balance caused by poor vibration.
