shell of bearings should not exceed 75℃，while the temperature of bearings should not exceed 35℃．

6.1泵運(yùn)轉(zhuǎn)中隨時(shí)注意是否異常振動(dòng)、噪聲。

    During operation，pay attention to whether extraordinary vibration&noise exists all the time．

6.2泵在長(zhǎng)期停止使用時(shí)，應(yīng)擰下底部螺塞，將泵內(nèi)積水排干凈，同時(shí)擰開(kāi)旋液分離器下部螺母，檢查是否有異物堵塞通道，清理干凈，然后裝回螺母擰緊。

    If the pump stops to put into use for a long time，the screw plug at the bosom of the pump body should be unscrewed SO as to drain water．In the meantime，the screw nut at the boRom of the separator should be unscrewed so as to check whether the routeway is jammed or not and make clean，fitting back and tighten after checking．

6．3泵的軸承每三個(gè)月加注一次黃油(3號(hào)鋰基潤(rùn)滑脂)，工作一萬(wàn)小時(shí)后檢查軸承滾珠是否有剝落現(xiàn)象，必要時(shí)應(yīng)予以更換。

    Lubricating grease should be added to the bearing of the pump every three months．The surface of the ball bearings should be examined whether exfoliation occurs after every 10,000 hours．Replace the bearing when necessary．

  6．4葉輪、密封環(huán)、機(jī)械密封每年檢查一次磨損及腐蝕情況，必要時(shí)應(yīng)予以更換。

    Annual interval inspection to impeller,sealing rings and mechanical sealing should be effected and check whether excessive wear and tear or corrosion occurs，replace them when necessary．
