出售铸铝循环油泵组件HSAD40R38U4PY

客户在使用螺杆泵的过程中，应当做到以下几点：
1、使用前仔细阅读使用说明，做到心中有数；
2、切勿自行拆卸，如遇特殊情况，应当和厂家联系，由厂家给予指导；
3、使用过程中不可以超高转速运转，螺杆泵在出厂之前已经设定好了转速，由电机带动运转，超高转速运转可能会使螺杆泵磨损，电机破损；
4、对于燃油类介质的螺杆泵，我们都会配备专门的防爆电机，如果客户的使用现场有易燃、易爆的物质，请注意使用安全和人员安全；
5、螺杆泵在长期不间断工作状态下，备件会加速磨损，会导致螺杆泵正常使用寿命缩短；
6、在冬季或者较冷区域，油可能会比较粘稠，使用的时候可以先运行几分钟，然后正常运转螺杆泵；
7、螺杆泵在使用较长的时间后，压力和流量可能会下降，这都是正常情况，这是因为长期使用过程中，螺杆和衬套磨损所致。

泵发热或异常噪声的处理办法：
1、泵内有严重的摩擦
检查原动机与主动螺杆的装配对中性。消除超差。检查螺杆泵衬套及滑动轴承的同轴度和是否有杂质。更换超差零件
以及消除间隙中的杂质或更换磨损零件。
2、机械密封回油孔堵塞
消除回油孔的障碍物
3、介质温度过高
降低温度
4、滑动轴承发生干摩擦
泵内灌满介质，并盘动主动螺杆几圈，使得滑动轴承有介质润滑
