每次检查需要检查现场的通风状况，要保证通风良好。1111
检查流量参数时，如果流量减小或出口压力不足，预示着螺杆和衬套的磨损，应拆修泵，并对磨损零部件予以更换(此建议供参考，拆修的时间和决定权由客户自己把握)
运行时的维护
U型泵轴封为机械密封，密封的润滑冷却由所输送的液体提供，机械密封不必定期维护，如泵的泄露过大，则需要更换机械密封。U型泵的轴承是内装的，润滑由所输送的液体提供，且产生的热量也由所输送的液体带走。
对于间断性操作，高温，高粘度，润滑性较差的介质，泵的实际使用寿命可能会缩短。因此我方建议定期检查泵的运转情况和轴承表面温度，并请在选型时与我厂技术部门咨询，以确定合理的转速。材料组合以及泵的结构形式。
如果啪啪声或隆隆声代替了泵工作时的嗡嗡声，或轴承处的温度急剧升高，这说明轴承出了故障，应尽快更换轴承。
